Companies currently encounter obstacles in networking, integration, and global manufacturing as mobile devices as well as computers increasingly facilitate commercial activities. Accordingly, we propose a new web-based enterprise resource planning (e-ERP) system that can be rapidly migrated from conventional on-site ERP systems. In this paper, by referring to Internet technologies and several key web topics, we explore the evolution of e-Commerce and ERP. We also discuss the applications of the proposed method based on an elastic model–view–controller e-ERP and software-as-a-service delivery. On the basis of information system architecture evaluation and realization results, we discuss the application of web technologies and web engineering models for the effective hosting of a reliable cloud ERP. In addition, on the basis of a review of the literature and related emerging technologies, we comparatively discuss several holistic frameworks of web application development from the technical and business perspectives. As indicated by the implementation results, the proposed approach can be used to effectively host a secure cloud ERP.

Multimedia platforms dealing with movie streaming and video-based short messages have increased the global Internet video traffic substantially in the last couple of years. Over the same period, multimedia on the Web has been standardized in terms of codecs and browserbased JavaScript APIs. However, today the technological challenges concerning the distribution of large video files are mainly tackled by scaling up capacities in cloud data centers, or relying on content delivery networks. Both approaches favor financially strong, large companies, while independent video providers with highly demanded videos are disadvantaged. Peer-to-peer streaming provides an alternative by shifting the data streams to the clients. In this article, we conceptualize different methods to move video delivery from centralized cloud infrastructures to end user devices.We discuss their strengths & weaknesses and present design considerations. To exemplify a particular approach, we showcase the implementation and evaluation of OakStreaming, our system that streams videos peer-to-peer via WebTorrent in HTML5. Particularly, we offer Web video providers a library that has various parameters, for instance to limit the bandwidth available for peer-topeer uploads. The resulting library is available as open source software on GitHub.

In recent years, agile methodologies have been consolidated and extended in organizations that develop software in Web environments. For this reason, the development methodology of these organizations will not only be related to Services, but also to the Web Engineering paradigm. These organizations are heading for incorporating software development methodologies whose paradigm can allow integration, naturally and in the earlier stages of Web applications develop with the services of the organization that described and published in the Services Portfolio. The aim of this study will be to analyze the current state of the art in the process of discovering services in early stages of agile software development with focus on those identified requirements that could be covered with the services included in the Service Portfolio. We have identified 20 relevant papers through conducting a double systematic literature review (SLR). It is concluded that no study has been found that can solve the entire process of discovering candidate services within an organization that cover the requirements of a new application developed with agile methodologies. At the same time, guidelines have been found to formalize the solution to this problem and fill in that gap of knowledge by proposing in a single process, the formalization of a requirement based on agile techniques, which can be managed against a Services Portfolio.

Data-intensive Web applications are usually developed by means of specific Web application frameworks, which provide, among other features, the proper tools to automate redundant tasks, e.g. the implementation of CRUD operations. However, although Model-Driven Web Engineering (MDWE) approaches have defined specific languages and tools to significantly reduce development efforts, the provision of such automation tools has been traditionally neglected. This paper presents AutoCRUD, a WebRatio plug-in automating the generation of CRUD operations in OMG Interacting Flow Modelling Language (IFML). It has been developed as a joint effort by academia and industry to assess its validity in a real scenario.

Most websites use interactive online forms as the main contact point between users and website owners (e.g. companies, governmental institutions, ect.). Therefore, a proper design of such forms is crucial to allow smooth information exchange. It can be decisive on the success or failure of an online transaction. Users mostly visit a website with an intention that is related to the content of that site (e.g. purchasing an article, gathering information). Hence, they do not visit a website with the intention or goal of filling in a web form. Let us illustrate this with an online shopping example: Once users have chosen the items that they wish to buy, they want to finish their shopping as quickly, easily and safely as possible. But to successfully complete the shopping process users have to provide some personal data such as shipping address or credit card information. In the users perception, an online form may be perceived as a hurdle. There is evidence that unusable web forms lead to customers aborting the transaction prematurely, resulting in loss of profit (Wroblewski, 2008). To prevent such dropouts from the buying process, a revision of the form is necessary. A successful redesign of a suboptimal online form may result in an increased completion rate in the range of 10%-40% (Wroblewski, 2008). For instance, the eBay User Experience and Design Group reported that a redesign of the eBay registration form made a significant contribution to eBay’s business and user success (Herman, 2004). The World Wide Web contains a wide range of different web form design solutions for similar interface aspects and problems. Exemplarily, Figure 1 shows four different ways of implementing and communicating format restrictions to users. It can be seen, that even website developers of major companies choose very different ways to solve the same problems. This raises several important questions: Are these solutions equivalent or are there ways that lead to superior web forms in terms of an enhanced usability? Would it not be advantageous to use similar solutions for similar problems, so that predictability for users can be increased? Are there different solutions that may be used depending on the developer’s intentions? In the last years a growing body of research and guidelines have been published on how to make online forms more usable. They answer to a certain extent the questions mentioned

With the rapid development of network technology and the rapid growth of e-commerce, complex wide-area distributed Web applications are emerging. Many traditional information management and database systems are being migrated to the Internet. The development of Web engineering is increasing gradually, and the proportion in software engineering technology and project development process will be larger and larger. Web engineering is an emerging and rapidly developing discipline. In order to ensure that Web engineering can develop as efficiently as traditional software engineering so as to avoid Web crisis, this paper will illustrate with the development and process examples of Web engineering technology. Combined with the software development and project management process and related results of a Web engineering project example, namely the driver training management information system (JPMIS), this paper proposes some applications based on the Web engineering software development and project management technology. This paper puts forward a concrete implementation method for the application of Web engineering in China’s small and medium-sized software enterprises.

The traditional definition of full stack development refers to a skill set that is required for writing software both for the frontend and backend of a web application or site. In recent years, the scope of full stack development has expanded significantly, though. Today, a full stack software developer is assumed to master various additional areas especially related to cloud infrastructure and deployment, message brokers and data analytics technologies. In addition, the emergence of Internet of Things (IoT) and the rapidly spreading use of AI/ML technologies are introducing additional skill set requirements. In this paper, we discuss the expectations for a modern full stack developer based on our industry observations, and argue that these expectations have significant implications for software and web engineering education.

Web Engineering becomes increasingly hungry for training data, as the application of machine learning (ML) methods in the field intensifies. Human-labeled datasets are particularly indispensable for ML-based validation and design of user interfaces (UIs). The production of such datasets is often outsourced to crowdworkers, who typically have lower motivation and payment compared to in-house staff, so the quality of their work becomes the paramount concern. In our paper, we explore the applicability of the trending fraud detection approach based on fit to power law in crowdsourced web UI labeling. On Amazon Mechanical Turk, 298 crowdworkers labeled over 30,000 UI elements in about 500 university homepage screenshots. We found a significant correlation between workers’ precisions and Kolmogorov-Smirnov statistics-based goodness-of-fit between the frequencies of UI elements in a worker’s output and power law. The obtained R2 = 0.504 was higher than the R2 = 0.432 baseline for the popular time-on-task parameter. Moreover, the distribution of UI elements’ frequencies is much less prone to manipulation by malicious crowdworkers, which is advantageous as a crowdsourced data quality control measure. The findings of our study suggest a certain resemblance between web UIs and natural language texts, in which word frequencies are known to comply with Zipf’s law.

This foreword introduces a summary of themes and papers of the Web2Touch (W2T) 2020–21 Track at the 29th IEEE WETICE Conference held as a virtual Conference, in October 2020.

This track shows how cooperative technologies based on knowledge representation, intelligent tools, and enhanced Web engineering can enhance collaborative work through smart service design and delivery, so it contributes to radically change the role of the semantic Web and applications.

This study is a preliminary case study examining the use of a free Web Development learning platform in order to en-deepen and facilitate further knowledge in App Development beginners. The use of CodeTrip.gr was examined with regard to perceived learning outcomes and effect on the need for cognition from the viewpoint of undergraduate non-major students with basic Web Engineering and programming skills. A didactic intervention including CodeTrip was conducted with a randomized sample of 18 undergraduate students, who were asked during the tool introduction and after doing the course, using qualitative analysis and validated items from technology and media effects research. The results are promising and support the idea that the user interface of the tool adds to the learning of the students since they show higher need for cognition scores and better self-evaluation after its use. Generalization of results is limited due to the small sample size. Future work includes the validation of the questionnaire with a bigger sample.

In this paper, we propose an architecturally novel approach to implementing purpose-based access control in practice. Different from previous proposals, our approach resides on the application instead of the data(base) layer. This allows for significantly better integration with established architectures and practices of real-world application engineering and to achieve database independence. To validate practical applicability, we provide two exemplary implementations and briefly assess the introduced overhead in matters of achievable throughputs. Results significantly depend on data and query type but basically suggest bearable overheads for realistic applications even though possible performance optimizations have not been implemented in our proofs-of-concept yet. Our approach thus proposes significantly better practical feasibility than previous ones and exhibits reasonable overheads. It therefore paves the way for purpose-based access control to be actually adopted in practice.

This paper documents a systematic approach (RAMLFlask) to extending Web application frameworks (Flask) to include support for interface-description languages (IDLs such as RAML) and code generation.

For last 15 years universities around the world are continuously developing effective curricula for Web Engineering in order to create good opportunities for graduates to cope up with IT-Software industries. From this study we will show the gap between the skill requirements of IT-Software industries and universities’ web course curricula. Also, we will provide a balanced and structured web course curriculum for any universities. Nowadays, there is a rapid development in web-based applications everywhere but most of our students are late bloomer in programming. So, to ease their difficulties in web sector we need a balanced web curriculum and effective teaching method. By this curriculum one can achieve an overall idea and a minimum view of web engineering which can be beneficial for them in further Web development. Students get a little knowledge in their university on Web Engineering because of the vastness of the contents and the small duration of semester. Our two-semester web course curricula will help them to overcome this problem. Two-semester web course curricula have a huge impact on achieving the minimum required skill in web development field in IT-Software industries. It will help to obtain most of the area of web related content also it will increase problem solving skill and versatile knowledge of web engineering in undergraduate life.

A robust technique for generating web navigation logs could be fundamental for applications not yet released, since developers could evaluate their applications as if they were used by real clients. This could allow to test and improve the applications faster and with lower costs, especially with respect to the usability and interaction aspects. In this paper we propose the application of deep learning techniques, like recurrent neural networks (RNN) and generative adversarial neural networks (GAN), aimed at generating high-quality weblogs, which can be used for automated testing and improvement of Web sites even before their release.

Software systems that are embedded in autonomous Cyber-Physical Systems (CPSs) usually have a large life-cycle, both during its development and in maintenance. This software evolves during its life-cycle in order to incorporate new requirements, bug fixes, and to deal with hardware obsolescence. The current process for developing and maintaining this software is very fragmented, which makes developing new software versions and deploying them in the CPSs extremely expensive. In other domains, such as web engineering, the phases of development and operation are tightly connected, making it possible to easily perform software updates of the system, and to obtain operational data that can be analyzed by engineers at development time. However, in spite of the rise of new communication technologies (e.g., 5G) providing an opportunity to acquire Design-Operation Continuum Engineering methods in the context of CPSs, there are still many complex issues that need to be addressed, such as the ones related with hardware-software co-design. Therefore, the process of Design-Operation Continuum Engineering for CPSs requires substantial changes with respect to the current fragmented software development process. In this paper, we build a taxonomy for Design-Operation Continuum Engineering of CPSs based on case studies from two different industrial domains involving CPSs (elevation and railway). This taxonomy is later used to elicit requirements from these two case studies in order to present a blueprint on adopting Design-Operation Continuum Engineering in any organization developing CPSs.

During the revolution of webs, several modern web applications appeared. After developing electronic devices, Ubiquitous web applications (UWA) becomes an important part of web applications. UWAs are a new type of web applications which are accessed in various contexts, meaning through different devices, by users with various interests, at any time from any place around the globe. The problem is UWA features made challenge during the process development of web engineering methods. Interaction Flow Modeling Language (IFML) is the recent modeling language has many concepts for developing interactions in web applications compared with other web engineering methods. In this paper, we present the role of IFML method to develop UWA features through analyzing IFML and designing a case study. The result of this paper becomes a guide for developers and increase the usability of IFML.

Web Engineering has ended up being one of the focal regimens disciplines for building Web-arranged applications. This paper proposes to reposition Web working to be dynamically unequivocal what precisely the Web is, by which we mean an interface advancement, yet an information structure, into which Web-arranged applications must be embedded. Progressively standard Web applications normally are just UIs to data storage facilities, while the years prior have shown that well-arranged Web-arranged applications can begin with no data, and get all their motivating force from being open and pulling in customers on a gigantic scale.

This article describes how cloud computing utilizes the benefits of web engineering and its applications by improving the performance and reducing the load on cloud providers. As the cloud is one of the emerging technology in the field of computing, it is used to provide various services to the user through the internet. One of the major concerns in cloud computing is accessibility of cloud. For estimating the availability of cloud, various load balancing algorithms are deployed in data centers of the cloud environment. Load balancing is a technique that distributes a signal load across various computers for optimizing resource usage, reducing response time, etc. There are different load balancing algorithms, for performing the load distribution across various centers. This article analyses different load balancing algorithms and develop a new algorithm for efficient load balancing. The proposed load balancing algorithm utilizes the concepts of web engineering to prioritize the request of end user using parsing technique, which will assign the resources to the end users based on the priority set by the data centers.

Website development is becoming a growing concern for all organizations in this world. However the process and lifecycle involved in their development is still uncertain. The Web based system development usually involves more heterogeneous stakeholders as compared to traditional software’s development construction. The process models used for the development of websites stands borrowed from the traditional software development approaches. The process of website development involves several fields of web engineering and multimedia applications which require altogether a different skill set and development processes. The growth of web based system has been exponential. An estimated size of public web and deep web has reached to 40 billion pages and where the pages are assembled on the fly in response to the user requests touches between 400 and 750 billion pages, respectively. The web based system size is continuously expanding like the universe after the big bang. Many researchers and practitioners have noted the rapid growth of internet for commercial purposes since its birth in 1990’s. The web presence allows small companies to compete comparatively at par with large enterprises which increases keenness for every organization to develop a website. An increase in the amount of web development work, forces the designers/webmasters working in different website development houses to carry out work in a well planned and systematic manner. The concerned organizations and different web development houses must, however follow specific methodologies/standards/guidelines recommended by various organizations for advancement in present web development process models. The adoption of traditional methodologies of web development leads to the production of poorly designed web applications which show variable performance across different browsing platforms and have high probability failure rate. This propagates in the lack of confidence during web development and ultimately moves towards Web-Crisis. In order to avoid Web-Crises, there is a desperate need of designing and developing the newer process models that are especially concerned with website development. As such there is a need of disciplined approach towards the development of web-based systems. Researches also suggest that there is a non uniform approach in web based systems development. The authors suggest that a specialized model for web development needs to be designed and developed to satisfy the dynamic categories of the stakeholders present worldwide. This paper discussed about the various traditional software and web development models popularly used in developing web applications and their suitability and effectiveness is compared which leads to the development of a successful web based applications. Various reasons which differentiate the traditional software development from web system development have also been worked out. The presences of specific features recommended in proposed framework are also tested by available methodologies. Finally, an initial framework is proposed which caters to the need of specific web development process model.

Web engineering is a systematic approach to develop web applications, and numerous web engineering methods have been proposed. These methods were extended through defining new models by using different mechanisms to capture the web application concepts. Due to the complexity rising of web applications, the web engineering methods cannot provide web solutions anymore. Even though Interaction Flow Modeling Language (IFML) is recently proposed as a new method for developing web applications, it has limitations. Therefore these methods need to be improved. In this paper, we present the ability of IFML extensibility to support new concerns from web applications. Moreover, we extend IFML through UML mechanisms to support new concerns from the context to the user interface. The new IFML solves the lack of context web application through defining a new model and becomes a new direction to develop concerns modern web applications.

The maturation of the Web platform has given rise to sophisticated and demanding Web applications such as interactive 3D visualization, audio and video software, and games. With that, efficiency and security of code on the Web has become more important than ever. Yet JavaScript as the only built-in language of the Web is not well-equipped to meet these requirements, especially as a compilation target. Engineers from the four major browser vendors have risen to the challenge and collaboratively designed a portable low-level bytecode called WebAssembly. It offers compact representation, efficient validation and compilation, and safe low to no-overhead execution. Rather than committing to a specific programming model, WebAssembly is an abstraction over modern hardware, making it language-, hardware-, and platform-independent, with use cases beyond just the Web. WebAssembly has been designed with a formal semantics from the start. We describe the motivation, design and formal semantics of WebAssembly and provide some preliminary experience with implementations.

Rapidly increasing information on the Internet and the World Wide Web can lead to information overload. Search engines become important tools to help WWW users to discover information. Exponential increases in published research papers, academic search engines become indispensable tools to search for papers in their expertise and related fields. In order to improve the quality of search, an academic search engines’ capability should be enhanced. This paper proposes a search engine for personalized rankings. In order to evaluate the performance of personalized rankings, thirty-five graduate students from the Department of Web Engineering and Mobile Application Development at Dhurakij Pundit University are participants in the research experiment. Participants are asked to use a prototype of an academic search engine to find and bookmark any research papers according to their interests, which would guarantee that each participants’ list of interesting research papers could be recorded. Normalized Discounted Cumulative Gain (NDCG) is used as a metric to determine the performance of the personalized rankings. The experiments suggest that the personalized rankings outperform the original search rankings. Hence, the proposed academic search engine with personalized ranking benefits research paper discovery.

Programming-illiterate users face barriers exploiting end-user programming tools.We offer a user-centric approach to support testing and validation in an end-user software engineering cycle.This approach allow end users to build error-free SOA-based software.Thus, end users can create applications to support their routine work on their own.The presented approach elicit the best practices and principles of the current SOTA. This paper addresses one of the major web end-user software engineering (WEUSE) challenges, namely, how to verify and validate software products built using a life cycle enacted by end-user programmers. Few end-user development support tools implement an engineering life cycle adapted to the needs of end users. End users do not have the programming knowledge, training or experience to perform development tasks requiring creativity. Elsewhere we published a life cycle adapted to this challenge. With the support of a wizard, end-user programmers follow this life cycle and develop rich internet applications (RIA) to meet specific end-user requirements. However, end-user programmers regard verification and validation activities as being secondary or unnecessary for opportunistic programming tasks. Hence, although the solutions that they develop may satisfy specific requirements, it is impossible to guarantee the quality or the reusability of this software either for this user or for other developments by future end-user programmers. The challenge, then, is to find means of adopting a verification and validation workflow and adding verification and validation activities to the existing WEUSE life cycle. This should not involve users having to make substantial changes to the type of work that they do or to their priorities. In this paper, we set out a verification and validation life cycle supported by a wizard that walks the user through test case-based component, integration and acceptance testing. This wizard is well-aligned with WEUSE's characteristic informality, ambiguity and opportunisticity. Users applying this verification and validation process manage to find bugs and errors that they would otherwise be unable to identify. They also receive instructions for error correction. This assures that their composite applications are of better quality and can be reliably reused. We also report a user study in which users develop web software with and without a wizard to drive verification and validation. The aim of this user study is to confirm the applicability and effectiveness of our wizard in the verification and validation of a RIA.

This research paper proposes experimental support to secure round trip engineering and use of security performance flexibility trusted operating systems for the designing of secure web applications. In this research paper, to address security concerns, we suggest use of trusted operating systems as a platform to run these web applications. For improving the performance of these web applications, we observe that all security checks in a trusted operating system are not necessary. As per our suggestion, various unnecessary security checks can be skipped by administrator, so that system performance of these web applications can improve. These unnecessary security checks, system calls and operations can be easily identified at the time of requirements elicitation. For example, as we know, the popular web servers deal with public information. The majority of this information is publicly readable and available to all users, but these users should not be able to alter this data. This research paper aims to support the efficiency of object-oriented class-based programming and object-oriented modeling in secure software development. The round trip engineering for the development of complex web applications, helps developers in code restructuring, identify probable bugs or deficiencies for probable improvements and helps from the analysis phase to the maintenance phase.

In the last few years, many security researchers proposed to endow the web platform with more rigorous foundations, thus allowing for a precise reasoning on web security issues. Given the complexity of the Web, however, research efforts in the area are scattered around many different topics and problems, and it is not easy to understand the import of formal methods on web security so far. In this survey we collect, classify and review existing proposals in the area of formal methods for web security, spanning many different topics: JavaScript security, browser security, web application security, and web protocol analysis. Based on the existing literature, we discuss recommendations for researchers working in the area to ensure their proposals have the right ingredients to be amenable for a large scale adoption.

Rapid web technology improvements in the last few years have powered software developers to quickly write responsive mobile-friendly applications. The innovative web frameworks and libraries make it easy to have same software code base for desktop and mobile devices. Single-page applications offer a more-native-app-like experience to the user. This also means a web application can easily be converted to a native mobile application if desired. This allows software products to be evolved continuously at a much faster pace with features added on daily basis. The software companies who can adopt these technologies will most likely see the benefit in the long run as they can offer new and modified products faster than their competitors. In this paper, we review some of the state-of-the-art web technologies, third-party libraries, and frameworks for quick interactive web development. Finally, we present a simple interactive browser-based, mobile friendly web application which was developed using one of the latest web development framework.

With the advancement in computing hardware and cloud services, many applications, imagined in the past and rejected as complicated or unfeasible, are becoming achievable. Artificial intelligence was able via new computing architecture to overcome big time consuming and insufficient data storage which permitted rapid models development and real-time applications. In this paper, we show via a challenging application how artificial intelligence can change the way we interact with our devices. Particularly, the paper attempts to develop an emotion-based search engine. In this sense, the user emotional features are used to select best Internet search results or to adapt them to user emotion. In this case, many scenarios are possible such as preventing bad influence of the search results on the user emotion. The idea presented in this solution can be adapted to other applications and brings new research challenges.

Agile methods have proved their applicability and efficiency in software development. Advantages of using agile methods include short development life-cycle times; multidisciplinary development teams; continuous evolution, immediacy, and reduced cost of change. Although some universities started including these methods in their curriculum, courses on practical practices for Agile methods at the undergraduate and graduate levels are still few. In this paper, an investigation is conducted to evaluate the impact of teaching practical agile methods in web engineering course on the learning outcomes of the software engineering students. This case study started by conducting a real-life business simulation inside a computer lab. Then, a questionnaire was prepared and disseminated in order to obtain the feedback on the students' perception on this teaching method. Afterward, the questionnaire results were analyzed and assessments for students were done to find out the impact of this educational technique on students' performance.

The chapter places the co-design method for WIS development from Chapter 11 into the context of web engineering. The chapter first discusses the conformity of the method with general software engineering quality frameworks such as SPICE and CMMI. It then continues with the investigation of architecture- and pattern-driven development, and finally illustrates them by taking a glance at the CottbusNet WIS and the underlying design and development decisions. This is rounded up by a discussion of WIS development dimensions.
