Behavioral adaptation is one of the first responses put in play by individuals to buffer environmental variations and to maintain homeostatic equilibrium with their environment. Microhabitat selection is pivotal for maximizing fitness, survival and reproduction, but how individuals process and exploit information acquired from the environment to make future microhabitat choice is yet understudied. In this study, we used outdoor mesocosms in which we introduced Strinati's cave salamanders (Speleomantes strinatii), to assess their behavioral patterns of shelter site fidelity. In each mesocosm three microhabitats were available to the salamanders: the leaf litter, a log and a rock. A total of 22 salamanders were tested over an 8-day period, 11 in autumn and 11 in spring. Salamanders shelter site fidelity was driven by both microhabitat humidity and previous experience obtained in the mesocosm. In our experiment, the time spent in the mesocosm was the main factor influencing shelter site fidelity, suggesting that previous experience and familiarity are important in salamanders' behavioral adaptation. Therefore, cave salamanders are capable of learning from experience when selecting their shelters, a behavior that could also be relevant during migration, colonization of new environments and adaptation to climate change. Highlights: How individuals exploit information gained from experience to select a microhabitat is understudied We found that plethodontid salamanders are capable of exploiting information on their environment to select the most suitable microhabiat [ABSTRACT FROM AUTHOR]

This article studies the epistemic dimension of current struggles over gender and sexual equality issues by analyzing digital media as epistemic systems transferring and producing gender knowledge. The analysis compares the representation and production of gender knowledge in German legacy and counterpublic media discourses on four dimensions related to the article-content level: media's issue focus and their positioning toward gender issues; media's referencing practices through hyperlinks, a unique affordance particular to digital spaces; and finally, the digital information ecologies created through these referencing practices. I conduct a quantitative content analysis and social network analysis of article content and hyperlink references in articles featuring gender issues, published in 16 German digital news outlets of legacy media and feminist, radical right, antifeminist men's rights activist, and Christian fundamentalist counterpublic media between December 2018 and November 2019. The results show that different types of media employ different modes of gender knowledge production. Anti-egalitarian counterpublic media show a rather reactive mode of gender knowledge production, while feminist media's mode of gender knowledge production is more autonomous. The digital information ecologies created through the references display varying levels of integration and fragmentation in relation to the mainstream public sphere, indicative of the underlying epistemic conflicts.

We investigate self-appraisals over time using a cognitive–ecological approach. We assume that ecologically, negative person attributes are more diverse than positive ones, while positive person attributes are more frequent than negative ones. We combine these ecological properties with the cognitive process of similarity- and differences-based social comparisons to predict temporal self-appraisals. The resulting cognitive–ecological model predicts that people should evaluate similarities with themselves over time positively, whereas differences would be evaluated more negatively. However, because positive attributes are reinforced over time relative to negative attributes, we predicted an asymmetry to emerge such that distinct attributes of the past self (past differences) would be most negative. Six experiments (total N = 1,796) and an integrative data analysis confirmed the cognitive–ecological model's predictions for temporal self-appraisals. However, we found no evidence for motivated self-perception across time. We discuss the implications of these findings for temporal self-appraisal theory and other aspects of self and identity.

For tourism crises, social media present a double-edged sword: while disseminating the damage caused by tourism crises, it also has the potential to enhance the destination's visibility and serve as a promotional tool. So, we cannot entirely negate the dissemination of tourism crises but rather proactively utilize its positive aspects to promote the sustainable development of the tourism destination image (TDI). Crisis events caused by management mistakes can be particularly damaging to people's trust in destination management organizations (DMOs), and a crowd crush is a common and highly damaging type of tourism crisis caused by public management mistakes. Thus, the purpose of this study is to summarize the factors that may positively influence TDI in the dissemination of tourism crises such as the Seoul Halloween crowd crush. This study takes the Seoul Halloween crowd crush as an example and constructs a theoretical model based on information ecology theory. The relationships of variables in the model were analyzed through structural equation modeling. The results show that information transparency, subject authority, and social media interactivity positively influence an organic cognitive image. Social connection and social media interactivity positively influence this organic affective image. Finally, this study provides targeted recommendations for DMOs, which is important for the restoration of TDI after crises. [ABSTRACT FROM AUTHOR]

Due to the information asymmetry and imperfect supervision system, the problem of information service quality of e-commerce platforms is becoming increasingly prominent. Based on the perspective of information ecology, this paper constructs a three-party evolutionary game model including merchants, e-commerce platforms and governments, and analyzes the dynamic process of the three-party game under bounded rationality, thereby characterizing the behavior and optimal strategies of information service quality control. We carry out numerical simulation using data of the Pinduoduo platform. The results show that the cost of each party, control strength of e-commerce platforms, proportion of margin deducted and other factors are important factors affecting the quality of information service; Only when the sum of the costs of passive management of e-commerce platforms, penalties for merchants, and the additional revenue generated from the active management exceeds the cost of the active management of the e-commerce platforms, it ensures effective control over the quality of information service in a stable market environment. Finally, some suggestions are put forward to optimize the e-commerce information service quality control. [ABSTRACT FROM AUTHOR]

The rapid advancement of digital health technologies offers a unique opportunity to enhance the effectiveness and reach of new media communication. This paper focuses on how digital health concepts can be integrated into new media platforms, characterized by their openness, virtualization, integration, and precision. We examine the types of new media communication and analyze the information ecosystem and ecological factors that influence the dissemination of digital health information. Through an ecological similarity analysis, we compare natural ecosystems with the science and technology communication ecosystems, across system structures, characteristics, and phenomena. To specifically assess the impact of new media in promoting digital health concepts, we developed a system dynamics model for new media communication. This model facilitates the analysis of system foundations, the sensitivity of new media communication influences, and the patterns of change in feature quantities of information technology tools. Our findings indicate that an 80% increase in the perceived usefulness of information can enhance the influence of new media communication by 6%. Conversely, an 80% decrease in information usefulness results in a 4% reduction in its influence compared to normal conditions. The role of the information subject as the main participant in new media is emphasized; their influence on information dissemination is significantly associated with their interests, and they play a more critical role than both the volume of information usefulness and the environmental influence of information. This study underscores the potential of new media as a powerful platform for the widespread adoption and effective communication of digital health initiatives. [ABSTRACT FROM AUTHOR]

Information technology has brought many advantages for communications and new possibilities for knowledge organization, but also many ethical challenges and risks for groups at the social margins such as the LGBTIQ+ communities. Self-identifying nomenclature from social media websites such as Grindr, XVideos, TikTok, and Scruf were gathered; keywords and phrases were extracted and arrayed by frequency distribution and compared across sites. There are obvious site-specific emphases: in XVideos the terms are more sexual, in Scruf they are more identity oriented. The aggregated data show different practices of representation of gay males reflecting their sexual and affective interests, likes, and desires. These findings reflect the act of defining and organizing the knowledge about the identity of the group based on what is desirable both in themselves and in others pertaining to the same. The resulting terms can be grouped into three classes: sexual desires/orientation desire, physical characteristics, and sexual roles or performances. In addition to gender self-denomination terms, there are terms that can represent a person's sexuality, including the description of the romantic or sexual attraction they feel. The snapshots of representation in different social applications studied here show a classification used and shared by the gay male community at present. [ABSTRACT FROM AUTHOR]

To address the risk warning of network public opinion for forest fires under uncertain information， a risk warning evaluation model based on evidential reasoning and intuitionistic fuzziness was established. Firstly， a network public opinion risk evaluation index system of forest fires was identified based on the perspective of the information ecosystem. Secondly， given the uncertainty and incompleteness of the index information in the evaluation process， the number of intuitionistic fuzziness was used to describe multiple index information by fuzzy rules. Then， the weight of the index system was calculated via intuitionistic fuzzy entropy and fuzzy analytic hierarchy process， and evidential reasoning theory was used to complete the integration of index information. Finally， the network public opinion risk level was determined by measuring the distances of intuitionistic fuzziness， and the ranking of network public opinion risks was determined by the utility value method. The practicability and effectiveness of the model were validated through three practical cases， providing new ideas and methods for the risk warning assessment of network public opinion for forest fires.

Patient-centric digital infrastructure can potentially enhance the efficiency of healthcare systems. However, even in developed nations, evidence suggests low adoption rates for such infrastructure and lack of support from clinicians is considered as one of the most critical hindering factors. In this study, we examine physicians' perceptions of the proposed large-scale information technology initiative in India that aims to transform the health sector and provide universal health coverage to all residents of India. We employed the information ecology lens to understand the broader changes in the healthcare system that could result from the initiative. We use focus group discussion and in-depth interviews to comprehend the perceptions of doctors about the initiative. Drawing upon Foucault's conceptualization of power, we find that physicians, the key stakeholders in this initiative, are skeptical about the changes in the locus of power in the new ecosystem. Specifically, they perceive that knowledge power has shifted from a historical "expert knowledge power" to power related to "data management." The physicians believe that changes are expected to manifest through monitoring, controlling, and managing the data rather than providing knowledge-based services. We present recommendations to engage physicians' perspectives in implementing large-scale patient-centric digital infrastructure. [ABSTRACT FROM AUTHOR]

[Purpose/Significance] Information ecology, as a kind of overall scenario of user information interaction behavior, reveals the basic logic of information flow among information elements in a particular environment. The study of information ecology in traditional information environment has been relatively mature. With the arrival of the metaverse, its characteristics of virtualization, immersion and decentralization have transformed user information interaction behavior, which in turn has brought about changes of the ecological interaction mechanism. We need to analyze the ecological mechanism of information interaction in the metaverse environment, in order to provide reference for relevant information theory research and promote the birth of metaverse informatics. [Method/Process] This paper stands on the information ecology perspective, takes the four ecological elements of information people, information, information environment and information technology as the entry point, and divides the information interaction ecology under the metaverse environment into three layers of architecture: information interaction, information data and information technology. Among them, the information interaction layer contains information users and information environment. Unlike the information ecological chain, each information user in the information interaction ecology under the metaverse environment is an integration of information producer, transmitter and consumer. Unlike the linear information flow in the information ecological chain, the information flow in the metaverse will show a wave-like diffusion. The information data layer provides the information resources in the information interaction ecology, and in this layer, we discuss the process from production to management of information resources under the metaverse environment. The information technology layer is the implementation path and basic support of the whole information interaction ecology, and in this layer we introduce several information technologies commonly used in the metaverse information interaction ecology. Through the above three-layer architecture, we have discussed the ecological composition of information interaction, information interaction logic, and information movement process as a whole to constitute the user information ecological mechanism under the metaverse enviornment. [Results/Conclusions] This paper constructs an ecological mechanism of user information interaction in the metaverse with a hierarchical architecture from the physical environment to the interaction scene, and provides strategies for the development of this mechanism from the perspectives of user, resource, technology, and governance. Taking the metaverse as the theoretical background, this study re-examines and expands the traditional information ecology theory, with the aim to provide a boost to the development of metaverse informatics. It is worth stating that the ecological mechanism of metaverse information interaction proposed in this paper is a theoretical prediction based on existing research, and the empirical conditions are insufficient.

With the proliferation of activity-tracking devices and other smart tools, more users leverage these personal informatics technologies to track their physical and fitness-related activities. The research on the benefits (and limitations) of these devices tends to focus on the use of a single tool, leaving out the interactions among multiple technologies, and how these interactions influence the way users perceive their affordances. Building from an ecological perspective, I extend this research by providing insight into the competitive and complementary relationships among activity tracking devices and other fitness-related and personal informatics technologies within the device ecology of technologies around the user. The affordances of these devices are therefore not enacted in isolation but are relational to understanding of other technological options and differing personal preferences and goals of the user.

With the rapid development of the Internet and the normalization of COVID- 19 epidemic prevention and control, Online health communities (OHCs) have gradually become one of the important ways for people to obtain health information, and users have to go through a series of information processing when facing the massive amount of data. Understanding the factors influencing user information processing is necessary to promote users’ health literacy, health knowledge popularization and health behavior shaping. Based on the Heuristic-Systematic Model (HSM), Information Ecology Theory, Privacy Trade-Off and Self-Efficacy Theory,we constructed a model of factors influencing user information processing in online health communities. We found that information quality and emotional support had indirect effects on heuristic and systematic information processing, and these effects were mediated by privacy concerns and self-efficacy. In our research model, systematic information processing was most positively influenced directly by self-efficacy. Privacy concerns had a direct negative correlation with both dual information processing pathways. Therefore, OHCs managers should develop relevant regulations to ensure the information quality in OHCs and improve privacy protection services to promote user information processing by improving users’ self-efficacy and reducing their privacy concerns. Providing a user-friendly and interactive environment for users is also recommended to create more emotional support, thus facilitating more systematic information processing. [ABSTRACT FROM AUTHOR]

Social information use is well documented across the animal kingdom, but how it influences ecological and evolutionary processes is only just beginning to be investigated. Here we evaluate how social transmission may influence species interactions and potentially change or create novel selection pressures by focusing on predator–prey interactions, one of the best studied examples of species coevolution. There is extensive research into how prey can use social information to avoid predators, but little synthesis of how social transmission among predators can influence the outcome of different stages of predation. Here we review evidence that predators use social information during 1) encounter, 2) detection, 3) identification, 4) approach, 5) subjugation and 6) consumption. We use this predation sequence framework to evaluate the implications of social information use on current theoretical predictions about predator–prey dynamics, and find that social transmission has the potential to alter selection pressures for prey defences at each predation stage. This suggests that considering social interactions can help answer open questions about species coevolution, and also predict how populations and communities respond to rapid human‐induced changes in the environment.

The use of digital platforms in social movements has given the Internet a central role in analyzing activism over the last decade. However, social networks' potential for social change has to be analyzed critically and take complex economic and political contexts where actors remain unequally powerful into consideration. Through a combined methodology, this article explores the tensions of free culture communities in Spain when using proprietary digital platforms. These communities include 1651 platforms, of which 1162 are proprietary, and 489 are free. They describe a complex ecology in which they use proprietary platforms or free alternatives depending on their ultimate goals. The logic of technological corporations is notably imposed when communities aim to communicate with outsiders as commercial social networks attract a significantly greater number of users.

Insinuation used in Internet journalistic announcements is the method of gaining activity on the website, which is implemented by the broadcaster in order to increase figures and obtain economic benefits. On the other hand, it is a socially harmful phenomenon – the person at whom the insinuation is addressed is put at risk of losing a positive image. Moreover, the viewer is exposed to contact with a disinformative message. The paper presents a method, deriving from communicative grammar, which makes it possible to demonstrate whether a given Internet journalistic announcement is based on insinuation.

The concept of the information and communication nature of the COVID-19 virus is presented, based on the results of research conducted by the author in the field of social communication. Some provisions of the author's theory of information viruses and their ability to influence the human body and large masses of the population are considered. It is proposed to consider the mechanism of the influence of coronavirus on the population as intersystem communication of the resonant field type. [ABSTRACT FROM AUTHOR]

The article is devoted to the ecology of cognitive-educational space of the digital age. The author points out that the need to obtain information from the outside world is one of the biological needs of man. The information environment is becoming the main habitat of modern man, spreading to all areas, including the educational one. The author wonders how digital educational technologies influence the formation of critical thinking, mental performance, the ability to be at ease with a lot of information and choose the right one from it? The author comes to the conclusion emphasizing that providing new opportunities for mastering knowledge, information society technologies often have a negative impact on the formation of consciousness and thinking of the younger generation and at the same time the impact of digital technology can lead to a change in the «cognitive portrait» of mankind, stimulating the development of emotional intelligence.

At present, the data service environment of university library has not been deeply analyzed, which leads to the problems of low utilization rate of base station and high failure rate of access users. Therefore, this paper puts forward the research on the optimization of university library's data service environment based on information ecology. Based on the perspective of information ecology, this paper analyzes the data service environment of university library, and establishes the optimization model of library data service environment. The model is used to integrate the data information of university library service environment to form the "content interaction" environment mode, and complete the optimization of university library data service environment. Based on this, a simulation experiment is designed to determine the number of limited resource blocks, power factor, bandwidth, minimum network rate, load standard deviation and the proportion of total load in the network. By comparing the utilization rate, user accommodation rate and access user failure rate of the library data service environment under different methods, the experimental results show that group A has 51 fewer base stations than before, and the access blocking rate is reduced by 8.5%; the op-timized library data service environment has higher base station utilization rate and user accommodation rate, and the success rate of access users has been significantly improved.

New social environments are emerging as spaces and places where work and life at home are no longer separate. Digital spaces and physical places have become intertwined: the 1st space is home, the 2nd is work, the 3rd is informal meeting places, while the 4th space represents different combinations of the previous ones. This paper describes the need for value-based designs of the 4th space through a transdisciplinary approach. We argue for a need to understand human interactions in physical and digital spaces from a user-centered perspective, meaning to understand user needs and preferences of digital content in physical and virtual spaces. Moreover, we point out the need to address identity, ethical, and legal requirements of these types of spaces. Finally, we address the need to connect emerging technologies such as AI, and design approaches such a gamification, with cognitive, structural, economic, social and technological challenges and opportunities of the 4th space.

The extreme “pollution” of the global information space has a negative impact on the social well-being of the population for media space is a kind of social space covered by the media. It is necessary to create an effective system of legal protection and social guarantees so that any citizen can receive minimal social protection and be protected from the negative impact of the adverse ecology of the mass media. Not everyone who is experiencing intense exposure to the media is aware of its negative effects including “fatigue syndrome”. To prevent it, D. Lewis proposes the following algorithm: use all information technologies of business and everyday communication; improve the methods of studying and processing data; set the right priorities for their analysis and use [26]. All media and actors that interact with them must master information culture, for which it is necessary to train specialists in the field of media ecology who are aware of the influence of media and social technologies on people’s feelings, thoughts, values and behavior. So far, experts on media ecology do not have a sufficient theoretical basis for conducting sociological research and identifying how the media forces the audience to structure what it sees, hears and feels in a certain way. Today’s media (especially electronic) can have a violent and undesirable effect - this is not only a psychological but also a philosophical, social and cultural problem that affects both children and adults. “Information anarchy” leads not only to moderate negative consequences but in some cases to “information ecocide” - destruction of traditional information and the media. Countering the contamination of the information environment should include the following steps: development of requirements for the content creation; monitoring of the collection, storage, processing and destruction of information; development of criteria for assessing the use of information. It is necessary to introduce a single rating system for information products, which will allow users to evaluate the quality of information sources according to the following criteria: purity of information; work on creating content; source coverage; quality (completeness) of information; sources of specific data sets; social-demographic characteristics of potential users.

The research is devoted to issues of the ecosystem of encyclopedic knowledge. The fact is that a reference information is now increasingly used as means of media manipulation in level of public consciousness (for political, ideological, and economic reasons). This is well traced on the example of online encyclopedias with free access to editing of posted information such as Wikipedia. This article is based on the description of the online analytical report on encyclopedias in Europe written by experts of the European Parliament.

The present study aims to represent the infoecology of bioinformatics, with an emphasis on the topic of relationships between studies in order to provide a scientific framework for infoecological investigations in this field. It was conducted using the co-occurrence analysis of the topic keywords of studies available on the Web of Science (WoS) Database from Clarivate Analytics and using the social network analysis. The infoecology of the studies' topic relationships indicated that the topics of the studies were inter-related as information elements, also known as infocenoses, in the form of seven basic clusters in the infotope of the WoS. According to the centrality indexes, topics such as proteomics, microarray, MicroRNA, genomics, gene expression, computational biology, database, and data mining had the largest topic relationships. Moreover, as emerging information elements, LNCRNA, big data, differentially expressed genes, Osteosarcoma, next-generation sequencing, protein-RNA-SEQ, protein interaction network, high-throughput sequencing metagenomics, and ITRAQ were found to create new topic relationships.

Diverted by the virality of social media and the powerful visibility of contemporary global protest, social movement research started to loose sight of the invisible and silent aspects of mobilization and underlying collective identities. Looking at a Balinese protest movement against land reclamation whose anti-capitalist and performative character remind of recent transnational protest, this article refocuses on collective identity and examines the local adoption of global protest. It analyses the evolving actor landscape and the negotiation processes between different cultures, ecologies, generations, media and networking strategies that prominently shape the Bali movement. The article conceptualizes the movement as an emerging information ecology and tracks its entanglements with local identity, national power politics and global activism through a culture and transmedia approach. It thus analyses the loud and the silent side of the protest and the movement's decision-making strategies that involve human and non-human agency, an aspect that is largely missing in current social movement debates. Going beyond simplified notions of strong leadership or leaderless networks, it tracks the difficult balancing acts between openness and closedness, between an ideally consensual and inclusive movement and the necessity to make strategic decisions in a specific local, national and transnational setting.

COVID-19 has shone a bright light on a number of failings and weaknesses in how current economic models handle information and knowledge. Some of these are familiar issues that have long been understood but not acted upon effectively – for example, the danger that current systems of intellectual property and patent protection are actually inimical to delivering a cost-effective vaccine available to all, whereas treating knowledge as a commons and a public good is much more likely to deliver efficient outcomes for the entire global population. But COVID-19 has also demonstrated that traditional models of knowledge production and dissemination are failing us; scientific knowledge is becoming weaponized and hyper-partisan, and confidence in this knowledge is falling. We believe that the challenges that COVID-19 has exposed in the information economy and ecology will be of increasing applicability across the whole spectrum of sustainability; sustainability scholars and policymakers need to understand and grasp them now if we are to avoid contagion into other sectors due to the preventable errors that have marred the global response to COVID-19.

The interface is an environment that in the past 50 years has been the subject of research by media ecologists. The main problems faced by researchers are the following: how to build comprehensive and deep relationships and connections between the physical environment, information resources, and the media. One solution is to introduce more interactive elements on media sites to visualize scenes and improve the quality of content. The article is devoted to the models of building an interactive interface using new technologies, considering the trends in the development of information ecology.

The invention of the printing press reduced higher education’s learning-resource scarcity. Access to learning increased, and this democratization of education indirectly contributed to the idea of political democracy in the western world. As part of these political changes, equilibrium was sought between the supply of expertise needed to promote prosperity and the demand for such expertise. This equilibrium has been elusive as the world economy shifts to a reliance on intellectual capital. To complicate matters, we now live in a world of staggering information abundance. How do we mange such boundless information? One answer may lie in viewing the social character of information (how information is used) as fundamental in setting information management agendas. This article presents a holistic approach to information management as one strategy to create effective management of information that starts with the individual and ends with collective knowledge and wisdom.

Based on the theory of information ecology, this paper conducts a quantitative analysis on the research literature of e-commerce ecosystem in China, and clarifies the research hotspots and development trends, so as to provide reference for subsequent studies. With the key words related literatures collected by CNKI as the data source, and the software CiteSpaceIV is used to draw a visual knowledge map, the distribution of e-commerce ecosystem research papers in China is statistically analyzed by econometric analysis method, and literature research is summarized and evaluated. The research results show that previous studies mainly focus on the concept of e-commerce ecosystem, and there are relatively few research results on the construction and evolution mechanism of e-commerce ecosystem, so the depth and breadth of research should be expanded. Applying the concept of e-commerce ecosystem to solve the problems in cross-border e-commerce will be the future research trend. [ABSTRACT FROM AUTHOR]

• An automatic bot recognition website based on the Chinese context is established. • Explore the impact of social bots on public opinion from the information ecosystem. • Social bots play an important moderating role in the information ecosystem. • Establish a link between social bots, information, and environment characteristics. Social bots exacerbate emotional chaos and network disorder during sudden public opinion outbreaks. Drawing on information ecology theory, we analyze how social bots as information person characteristics influence information characteristics represented by topic tendency and sentiment spreading and environmental characteristics represented by information diffusion and network influence, and further discuss the conditional role played by social bots in public opinion dynamics. By comparing different machine learning models, the study selects the XGBoost model with the highest accuracy to identify the type of social bots with specific automation features in the Chinese context. Meanwhile, based on the representative public health emergency, the study uses a large-scale social media dataset (N = 328539) to explore how social bots affect multi-dimensional public opinion dynamics in the information ecosystem. It was found that the information published by social bots and human users has an entirely different dissemination mechanism, and social bots have a significant impact on topic tendency, sentiment spreading, information diffusion, and network influence in cyberspace. Moreover, social bots also play an important moderating role in the information diffusion and network influence of affective information. Relevant findings provide a practical reference for the recognition and prevention of social bots, and help emergency management departments to stabilize public sentiments by intervening in the behavior of social bots, weakening the influence of negative public opinion, and promoting the management of public opinions in emergencies and the maintenance of network order.

Purpose: Information ecology refers to the effect of environment on information elements and reaction among information elements in the context and environment which has been used as reactions of subject categories in this research. Therefore, in identifying information ecology, we studied the reaction of subject categories of Knowledge and Information Science with other subjects such as information and communication technology (ICT) in 2001-2011 different journals of knowledge and information science. Methodology: This was a quantitative content analysis regarding the identification of subject categories of 2510 papers in 9 journals of knowledge and information science indexed in ISC (Islamic Science Citation database). The data collection tool was the schedule of classifying subject categories of KIS confirmed by Delphi Panel in two stages. Findings: The results showed that all subject categories of KIS have reactions with other subject categories and the reaction of subject categories with information and communication technology (ICT) had more share. In contrast, the reaction of other subject categories in different of science have taken less share. The results of comparing reaction of subject categories ICT separated by journals show the reaction of subject categories with ICT in journals of library and information science of Astan Ghods Razavi, the Iranian Journal of Information Processing & Management, Journal of Academic Librarianship and Information Research, and Research on Information Science & Public Libraries and Informology in the second period (2006-2011) was higher than that in the first period (2001-2005).
