There is a rapidly growing need to evaluate sensor network functionality and performance in the context of the larger environment of infrastructure and applications in which the sensor network is organically embedded. This need, which is motivated by complex applications related to national security operations, leads to a paradigm fundamentally different from that of traditional data networks. ...

Health care information systems are becoming more and more computerized. A huge amount of health related information needs to be stored and analysed, and with the aid of computer systems this can be done faster and more efficiently. The Agent Oriented paradigm provides an alternative way of developing medical based systems. This article presents an initial exploration of the analysis and design...

With the increasing use of entities in serving people’s daily information needs, recognizing synonyms—different ways people refer to the same entity—has become a crucial task for many entity–leveraging applications. Previous works often take a “literal” view of the entity, i.e., its string name. In this work, we propose adopting a “structured” view of each entity by considering not only its str...

Distributed information retrieval comes into play when a user wants to get information from di erent sources in parallel. One of the challenges of this topic is the Collection Fusion problem: The distinct result lists of the underlying information retrieval systems (IR) have to be fused to give a global relevance-ranked result list according to the user's information need. In this paper several...

User studies focusing upon real-life music information needs, uses and seeking behaviours are still very scarce in the music information retrieval (MIR) and music digital library (MDL) fields. We are conducting a multigroup survey in an attempt to acquire information that can help eradicate false assumptions in designing MIR systems. Our goal is to provide an empirical basis for MIR/MDL system ...

Although Wikipedia has emerged as a powerful collaborative Encyclopedia on the Web, it is only partially multilingual as most of the content is in English and a small number of other languages. In real-life scenarios, nonEnglish users in general and ESL/EFL 1 users in particular, have a need to search for relevant English Wikipedia articles as no relevant articles are available in their languag...

The aim of this paper is to illustrate, by way of a few case studies, the value of model-based task analysis in interaction and design specification of Web mashups. Task analysis is recognized as one fundamental way to focus on the specific user needs and to improve the general understanding of how users may interact with a user interface to accomplish a given goal when using an interactive sys...

Recently, a new data mining methodology, Domain Driven Data Mining (DM), has been developed. On top of data-centered pattern mining, DM generally targets the actionable knowledge discovery under domainspecific circumstances. It strongly appreciates the involvement of domain intelligence in the whole process of data mining, and consequently leads to the deliverables that can satisfy business use...

Medical errors are common, costly and often preventable. Work in understanding the proximal causes of medical errors demonstrates that systems failures predispose to adverse clinical events. Most of these systems failures are due to lack of appropriate information at the appropriate time during the course of clinical care. Problems with clinical communication are common proximal causes of medic...
