    Multi-Agent Systems may be classified as containing No Direct Interactions, Simple Interactions or Complex, Conditional Interactions between agents. This paper argues and illustrates that models with simple interactions, even though possibly less fascinating for the Multi-agent system theorists than complex interaction models are, deserve more attention in the Multi-agent system community. Simple interaction models may contain social learning and reciprocal relationships. Maybe most importantly, Simple interaction models enable cross-scale connections by linking local to global actors in their local and global ‘life worlds'.

    eHealth services but also general Health services emphasize patient record management. Unfortunately the information in these records is not used to provide quicker, personalized eHealth services and appropriate treatment. Especially in a low infrastructure context where Health service providers are often overwhelmed by large numbers leads to degradation in service delivery. Domain specific service discovery with personalization aims at providing user-centric services. This is very important in a low infrastructure context where demands on the health services range over various aspects that reflect the massive variation in social economic development synonymous with developing countries. The focus of this paper is a framework for eHealth service discovery in low infrastructure context. To do this, we categorize the context of users and augment it with user specific profile. Our framework provides ontology based, context-aware semantic and personalized services.

International Journal of Education and Development using Information and Communication Technology (IJEDICT), 2010, Vol. 6, Issue 4, pp.83-101.

    The adoption and use of ICT to enhance and facilitate Knowledge Management (KM) has brought to focus the urgent need to come out with new methods, tools and techniques in the development of KM systems frameworks, knowledge processes and knowledge technologies to promote effective management of knowledge for improved service deliveries in higher education. To succeed in KM, higher education institutions must endeavor to effectively link KM initiatives and processes with their ever-changing needs to advance their goals. Addressing these challenges call for a new conceptual framework and expanded research agenda to ensure success in the utilization of ICT in KM. Using the synergies from Stankosky's (2005) KM pillar for enterprise learning together with the task/technology fit theory (Goodhue and Thompson, 1995) to form the basis for defining our approach, this paper proposes a conceptual framework for using ICT to enhance KM in higher education. In addition, the paper identifies several research issues to bridge the gap that currently exists between the requirements of theory building and testing to address the different emerging challenges in using ICT to enhance KM in higher education.

    We have investigated the search behaviour of the library searcher using the log data from The European Library (TEL). We were especially interested in how this behaviour compares to the search behaviour of ad-hoc searchers, represented by log data in the MSN search engine. At first sight, the two data sets mainly differ in the topics of the queries entered and their multi-lingual vs. mono-lingual content.

    When studying user behaviour, session information is very important: how does the user navigate through the engine's interface? We visualized the TEL users' interactions with the system by creating a transition network for the users' intra-session actions. In general, we think that research into user behaviour on the basis of search engine logs can be very informative for the evaluation of search engine interfaces.

    Personalization of services based on user preferences and user context facilitates service discovery. Several researches have been conducted on service personalization, however, little has been done to allow non-literate users to query services based on their educational level, their linguistic, cognitive, physiological and psychological abilities. In developing countries users have diversified culture, language and traditional values. As a result it is valuable to design the services on the basis of user literacy level, user preference and user context.

  3. Pscheidt, M. and Weide, Th.P. van der, Sustainability of collaborative information system development projects - a North-South case study. IDIA2010

    There are attempts of developing countries to move from a predominant consumer-orientation to become more active producers of software and information systems (IS), thereby reaching a better, more self-determined position to solve local problems. To achieve success of IS development projects, sustainability plays a critical role. This paper examines the concept of sustainability and its common underlying characteristics, and then derives key principles of sustainability in a case study of a North-South IS development project. Collaborative IS development is characterized by several levels of interconnections and issues of ownership and control. IS development projects run through several phases and have to keep up with changing requirements of the implementing organization, hence external consultancy by donor projects typically covers only limited phases of the IS life cycle. Nevertheless, projects can facilitate sustainable outcomes by a focus on utility, capabilities and embedding.

  4. Zlotnikova, I.Y. and Weide, Th.P. van der, An Approach to Modeling ICT Educational Policies in African Countries. IDIA2010

    Based on the research of sub-Saharan African countries, this paper proposes a model for ICT educational policies. In this model, the authors identify parameters (political, socio-economic, demographic, geographic, cultural etc.) that contribute to the success or failure of ICT educational policies, making a distinction between components and parameters. Then Formal Concept Analysis is applied to identify special stable combinations of components and parameters. These stable combinations are proposed as a managerial framework to apply the proposed model in practice. Currently the model has a qualitative, descriptive character. An initial rough setting of the quantitative parameters is taken to get an impression of the potential of the proposed model.

  5. Koopmans, F.T.W. and Weide, Th.P. van der, Broader perception for local community identification. International Conference on Knowledge Discovery and Information Retrieval, KDIR2010, Portugal

    A local community identification algorithm can identify the network community of a given start node without knowledge of the entire network. Such algorithms only consider nodes within or directly adjacent to the local community. Therefor a local algorithm is more effective than an algorithm that partitions the entire network when only a small portion of a large network is of interest or when it is difficult to obtain information about the network (such as the world wide web). However, local algorithms cannot deliver the same quality as their global counterparts that use the entire network. We propose an improvement to local community identification algorithms that will decrease the gap between relevant network knowledge of global and local methods. Benchmarks on synthetic networks show our approach increases the quality of locally identified communities in general and a decrease of the dependency on specific source nodes.

    Search engine queries are often very short and usually lack explicit semantic structure or indication of intent. Recog- nizing intent is receiving increased attention since it enables a search engine to trigger a dedicated answer and presen- tation module. This way search engines increasingly move from a document ranking system to an answer facility. In this study we investigate whether it is possible to infer a hidden wh-request from a subset of all two- and three-word queries, based on the syntactic form of the queries. By ana- lyzing dependency relations between the terms in the queries we gain insight in the structure of queries that are likely to have a wh-question as underlying intent. The goal of recon- structing a question from a keyword query is to be able to provide the user with an answer to that question, instead of only returning a list of documents.

    The increasing ability to access Internet via mobile devices means that learning objects can be deployed and utilized on those devices. Increasing research attention has been accorded to the design and development of reusable learning objects for tethered and mobile based learning management systems. Little research has been undertaken in regard to pedagogical models geared towards effective deployment and utilization of mLearning objects in different contexts and particularly of developing countries. This paper uses the Design Research approach to develop a UML based model for instantiating applications for deploying and utilizing learning objects on multi-generation order mobile phones in developing countries of Africa.

  8. Li, R. and Weide, Th.P. van der, Language Models for XML Element Retrieval. INEX 2009

    In this paper we describe our participation in the INEX 2009 ad-hoc track. We participated in all four retrieval tasks (thorough, focused, relevant-in-context, best-in-context) and report initial findings based on a single set of measure for all tasks. In this first participation, we test two ideas: (1) evaluate the performance of standard IR engines used in full document retrieval and XML element retrieval; (2) investigate if document structure can lead to more accurate and focused retrieval result. We find: 1) the full document retrieval outperforms the XML element retrieval using language model based on Dirichlet priors; 2) the element relevance score itself can be used to remove overlapping element results effectively.

    An important aspect of human sociality is our ability to under- stand the actions of others as being goal-directed. Recently, the now classic rational approach to explaining this ability has been given a formal incarnation in the Bayesian Inverse Plan- ning (BIP) model of Baker, Saxe, and Tenenbaum (2009). The BIP model enjoys considerable empirical support when tested on 'toy domains'. Yet, like many Bayesian models of cogni- tion, it faces the charge of computational intractability: i.e., the computations that the model postulates may be too resource demanding for the model to be scalable to domains of real- world complexity. In this paper, we investigate ways in which the BIP model can possibly parry the charge. We will show that there are specific conditions under which the computations postulated by the model are tractable, despite the model being rational and Bayesian.

  10. Li, R. and Weide, Th.P. van der, Deriving Implicit User Feedback from Partial URLs for Effective Web Page Retrieval. RIAO 2010

    User click-throughs provide a search context for understanding the user need of complex information. This paper re-examines the effectiveness of this approach when based on partial clicked data using the language modeling framework. We expand the original query by topical terms derived from clicked Web pages and enhance early precision via a more compact document representation. Since our URLs of Web pages are stripped, we first reconstruct them at different levels based on different collections. Our experimental results on the GOV2 test collection and AOL query log show improvement by 31.7% and 28.3% significantly in statMAP for two sources of reconstruction and 153 ad-hoc queries. Our model also outperforms pseudo relevance feedback.

  4. Omona, W. and Weide, Th.P. van der and Lubega, J.T., Grounded Theory Approach and Knowledge Management Research: Applicability, Limitations and Ways Forward.

    Knowledge management (KM) is currently an emerging discipline in higher education, and its effective implementation is becoming a precondition for success in an increasingly globalized knowledge economy. Because it is interdisciplinary in nature, carrying out a research in KM requires deciding on appropriate research strategies that should be used to enable objectives of a study to be undertaken to be achieved. Based on review and analysis of available literatures, this paper looks at the paradigms in KM research and examines in details the applicability and limitations of grounded theory approach in carrying out KM research. Using the explanation that KM research is a human activity system which requires both soft and hard systems methodologies to achieve study goals, a research methodological strategy is proposed for carrying out a study to develop a framework for KM using ICT in higher education in Uganda as part of an on-going study. As well as contributing theoretically to the literatures on KM by providing insights into the applicability and limitations of grounded theory approach in KM research, this paper further seek to propose a methodological strategy that can be applied in carrying out related studies.
