In this paper, we examine the use of knowledge query technology as applied to conversation bots in the instant messaging environment. Hence, we designed an artificial intelligent conversation robot or bots called Artificial Intelligence Natural language Identity (hereafter, AINI) to mimic human conversation. Our goal is to introduce a Domain Matrix Knowledge Model and an Automated Knowledge Extraction Agent (AKEA) to create AINI's knowledge bases, and in turn provide intelligent query mechanisms. We report an evaluation on the collection and analysis of a corpus containing over 3280 utterances in a series of real instant messages exchanged between the AINI conversation bot and 65 online ''buddies''. About 1721 utterances were produced by AINI, 88.03% were from open-domain knowledge, 2.15% from domain-specific knowledge base and 9.82% were inappropriate and amusing responses. These results show that domain knowledge plays significant roles in conversations between two or more human users and in human-machine conversation.

Universities teach project management to information technology (IT) students. The project management principles that students previously have learned often are put into practice in a project course that is intended to give final-year students the experience of applying their knowledge to real or simulated projects. This article reports on research that investigated the use and usefulness of project management in student IT projects. The results show that there was a wide range in the application of project management practices, with students being more likely to produce the initial documentation associated with some of the project management knowledge areas than to make use of it throughout the project to monitor the project’s progress. The results also showed that the number of project management guidelines applied in student projects was not linked to IT project success. However, there was a strong relationship between project management plan quality and obtaining a good software product.

College and university environments offer one of the best opportunities for the adoption of smart card technology. This study explores the possibility of developing smart card as a university application and investigates whether it will help to reduce the university business administration procedures as well as increase their service efficiency. This involved investigating the response of two groups (experienced and non-experienced) towards the adoption or the intention to embrace the technology of a university smart card. Studying the experiences gained by Nanyang Technological University (NTU, Singapore) students using smart card application in their university may provide an insightful picture for a university that is considering adopting such a technological innovation.Results show that compatibility pre-adoption construct is the key element that plays the most influential factor in motivating local students for adoption. This suggests that to ensure adoption, it is important to guarantee that the university smart cards are socially acceptable among the university students (fit well with the students' norm and environment). Another implication of this study is that Murdoch University (MU, Australia) students would most probably be willing to accept the adoption of a university smart card given that the results show MU students' response of (probability= 168/200) and NTU students' response of 100% (probability= 50/50) acceptance toward using their university smart card. The results also show a significant culture difference between MU students and NTU students, indicating that smart card manufacturer should take note of the ranking of user preference when designing a university smart card in order to optimize the adoption process.

Universities teach project management to information technology (IT) students. The project management principles that students have previously learned are often put into practice in a project course, intended to give final year students the experience of applying their knowledge to real or simulated projects. This paper reports on research that investigated the use of, and usefulness of, project management in student IT projects. The results show that there was a wide range in the application of project management practices, with students being more likely to produce the initial documentation associated with some of the project management knowledge areas than to make use of it throughout the project to monitor the project’s progress. The results also showed that the number of project management guidelines applied in student projects was not linked with IT project success. However, there was a strong relationship between project management plan quality and obtaining a good software product.

In this paper, we proposed a new framework to incorporate an intelligent agent software robot into a crisis communication portal (CCNet) in order to send alert news to subscribed users via email and other mobile services such as Short Message Service (SMS), Multimedia Messaging Service (MMS) and General Packet Radio Services (GPRS). The content on the mobile services can be delivered either through mobile phone or Personal Digital Assistance (PDA). This research has shown that with our proposed framework, the embodied conversation agents system can handle questions intelligently with our multilayer architecture. At the same time, the extended framework can take care of delivery content through a more humanoid interface on mobile devices., {"references":["L. Palen, M. Salzman, and E.

Complex engineering applications demand powerful computing resources. An object based distributed system is suitable for such applications due to the inherent parallelism nature in the object based computing model. As the model is based on message passing, which in turns relies on location transparent object names, an efficient name translation system is therefore required to map the object names to the corresponding physical addresses dynamically. In this paper, we propose a heuristic distributed search algorithm, the hierarchy random walker (HRW), to take advantage of the locality of object communications thereby increasing the overall system performance. Analysis of the simulation results from a number of benchmark programs have demonstrated that the benefits of the proposed algorithm are in terms of flexibility and efficient to locate the most used objects. The approach will be applied to intelligent techniques for engineering problems.

In times of crisis, an effective communication mechanism is paramount in providing accurate and timely information to the community. In this paper we study the use of an intelligent embodied conversational agent (ECA) as the front end interface with the public for a Crisis Communication Network Portal (CCNet). The proposed system, CCNet, is an integration of the intelligent conversation agent, AINI, and an Automated Knowledge Extraction Agent (AKEA). AKEA retrieves first hand information from relevant sources such as government departments and news channels. In this paper, we compare the interaction of AINI against two popular search engines, two question answering systems and two conversational systems.

This paper presents a novel framework for modeling embodied conversational agent for crisis communication focusing on the H5N1 pandemic crisis. Our system aims to cope with the most challenging issue on the maintenance of an engaging while convincing conversation. What primarily distinguishes our system from other conversational agent systems is that the human-computer conversation takes place within the context of H5N1 pandemic crisis. A Crisis Communication Network, called CCNet, is established based on a novel algorithm incorporating natural language query and embodied conversation agent simultaneously. Another significant contribution of our work is the development of a Automated Knowledge Extraction Agent (AKEA) to capitalize on the tremendous amount of data that is now available online to support our experiments. What makes our system differs from typical conversational agents is the attempt to move away from strictly task-oriented dialogue.

In this paper, we examine the readability of the human-machine conversation transcripts in the instant messaging environment based on the Gunning-fog index. The study is based on an embodied conversational agent (ECA) called artificial intelligent natural-language identity (AINI) which was designed to mimic human conversation. The ECA is also expected to supply answers with a sense of humour. We report on the collection and analysis of a corpus containing over 3,280 utterances in a series of real instant messages exchanged between AINI with 65 online "buddies".

In 2002, the Thai government has endorsed an information technology policy framework entitled "Thailand Vision towards a Knowledge-Based Economy (IT 2010)". The policy emphasises the roles of information technology for the enablement and facilitation of economic and social development. One of the objectives is to develop the ability of small and medium enterprises (SMEs) to compete in the world market. Although there are successful cases, majority of the companies among the Thai SMEs sector are still in an early stage of utilising e-commerce technologies to reap benefits from new opportunities. Therefore, there is a need to understand, to extract and to acquire knowledge about the adoption and use of the e-commerce technologies by SMEs in Thailand. Technology acceptance model (TAM) has been applied to many studies on the adoption and use of innovation and technologies. This proposed study intends to use a modified TAM named TECTAM (Thai E-commerce Technology Acceptance Model), as a research tool and model to study e-commerce acceptance among the Thailand's SMEs sector. The predominant dimensions of this study are based on TAM perceived usefulness (PU) and perceived ease of use (PEOU). In terms of PU, the near-term and long-term usefulness are considered. On the other hand, the PEOU will be concerned with the social influence processes and the cognitive instrumental processes. In addition, this study will investigate how to increase the benefits from the relationship between TAM and other approaches. Finally, the study aims to apply the use of TECTAM model in terms of e-commerce technologies acceptance and how they could be used While the project is in a preliminary stage, the paper will detail the proposed methodology and approach of this project.

This paper reports the development and running of the first Games Development and Programming unit at Murdoch University, Western Australia. Unlike other Games courses which have been repackaged or re-modeled from existing multimedia courses, the proposed course and units are focused on meeting the needs of the industry and high level of academic standard. As such, great demands have been placed on the students. The unit objectives, structure and examples of assignments from the first batch of students are described in this paper. Experience has shown that the students were able to perform well with positive encouragement. Ability to work in a team also proved to be an important factor. This has shown to be related to the standard of the students’ work and it is also an essential attribute expected by the industry.
