Foundations Of Ontology-Based Mas Methodologies, Ghassan Beydoun, Numi Tran, Graham Low, Brian Henderson-Sellers

Associate Professor Ghassan Beydoun

Support for software extensibility, interoperability and reuse are critical concerns for long term commercial viability of any MAS and they underpin the eventual adoption of agent technology by industry. Existing AOSE methodologies lack adequate support for these concerns. We argue in this paper that a methodology that uses ontologies as a central modelling artifact, beyond the analysis phase, is better equipped to address those concerns.

We observe that the influence of ontologies in Knowledge-based Systems (KBS) methodologies extended well beyond the initial analysis phase, leading to domain-independent KBS methodologies in the ’90s. We reflect on those lessons and on the …

Identity-Based On-Line/Off-Line Signcryption, Dongdong Sun, Xinyi Huang, Yi Mu, Willy Susilo

Professor Willy Susilo

We present an identity-based on-line/off-line signcryption scheme, where most of computations are carried out when the message is not available(i.e., off-line stage) and the on-line part of our scheme does not require any exponent computations and therefore is very efficient. It combines the functionalities of signature and encryption and is provably secure in the random oracle model. We also show that our scheme is indistinguishable against adaptive chosen-ciphertext attacks (IND-IDSC-CCA2) and is existentially unforgeable against adaptive chosen-message attacks (EF-IDSC-ACMA).

Development Of A Web-Based Student Enquiry System: Integration Of Ontology And Cbr, Sim K. Lau, Seung Hwan Kang

Dr Sim Kim Lau

This paper discusses the development o f a web-based student enquiry system using techniques in case-based reasoning combined with advances in ontology. The system functions as an online enquiry front-desk to allow prospective students to fin d out if they are eligible for admission to a post-graduate course in an Australian University. Ontology is applied in the system to ensure explicit specifications of concept and definition of terminology can be achieved in the web-based system. The system applies case-based reasoning technique to handle the query.

Usability Testing Of Public Health Web-Based Information Systems, Sumayya Banna, Kholoud Alkayid, Helen M. Hasan, Joseph A. Meloche

Sumayya a Banna

While the Internet provides many opportunities for increased levels of care and access to information services in the area of public health, many web designers are not yet taking full advantage of its potential. This study looks at Intensive Care and Palliative Care, as important instances where health informatics could improve public web-based services, in meeting the particular information needs of family members of critically and chronically ill patients. This study is significant in adopting an approach to the usability testing of websites based on concepts from Activity Theory. This takes a realistic and practical approach, which identifies the purpose …

Dimension-Based Versus Relation-Based Brand Name Design: A Test Of Different Psycholinguistic Theories, Tobias Langner, Franz-Rudolf Esch, John R. Rossiter

John Rossiter

Conveying distinctive and coherent brand associations is a key concern of modem brand management. Brands with a concise, consumer-relevant, and unique brand image are preferred by consumers. This study considers the contribution brand names can provide to building customer based brand equity. Recent cognitive theories of conceptual combination fonn the theoretical basis for analyzing consumer reactions toward brand names. Following these theories, three techniques to integrate brand name and product are developed. Reaction time measurements and association tests show that the techniques presented are an effective and efficient means to convey a brand's image.

Articulating Knowledge Work: The Contributions Of Activity Theory And Task-Based Knowledge Management, Henry Linger, Frada Burstein, Helen M. Hasan

Helen Hasan

This chapter addresses issues of knowledge work in organisations with a concern that mainstream knowledge management (KM) has fallen short of expectations. The real nature of knowledge work remains hidden, and thus inaccessible, to those who are trying to improve organisational outcomes through KM practices. The authors have conducted independent research within a new discourse on knowledge work in the context of modem complex organisations, the results of which are converging to a common understanding of this critical phenomenon. Their two theoretical frameworks, one task-based and one activity-based, are described here as eminently suited to this research. Two sets of …
