A signific~mt component of a user raodel in au infornration-seeking dialogue is tim task-related plazl motivating the information-seeker's queries. A number of researchers have Irmdeled the plan inference process and used these models to design more robust natural language interfaces. However in each case, it has been assumed that the system's context model and the plan under construction by th...

BACKGROUND Somatisation is particularly challenging in multicultural contexts where patients and physicians often differ in terms of their illness-related beliefs and practices and health care expectations. This paper reports on a exploratory study aimed at better understanding how asylum seeker and refugee patients from the former country of Yugoslavia who were identified by their physicians a...

We present a new paradigm for multimedia information access, named the “Holistic” information access paradigm, and its underlying architecture, the 3C (Content, context, and common-background) knowledge integration architecture. The holistic information access approach is context-sensitive, concept-based, and proactive. “Context-sensitive” means that the approach incorporates the characteristic...

The rapid deployment of wireless mesh networks across universities and enterprises, and the pervasiveness of mobile devices equipped with Wi-Fi connectivity, has resulted in a scenario wherein end users have the option to choose from a multitude of access points at any given location. Moreover, with the increasing availability of rich online content, there has been a steady increase in mobile I...

High dimensional data values are processed and optimized with feature selection process. A feature selection algorithm is constructed with the consideration of efficiency and effectiveness factors. The efficiency concerns the time required to find a subset of features. The effectiveness is related to the quality of the subset of features. 3 dimensional data models are constructed with object, a...

This study examined the incidence of suicide and self-harm in asylum seekers in the UK, both those in detention and in the community. The investigation revealed that data recording is seriously flawed or sometimes non-existent. However, the scanty data those were available from Immigration Removal Centres, coroners' records and Prison Ombudsman's reports showed high levels of self-harm and suic...

This paper describes Seeker, a platform for large-scale text analytics, and SemTag, an application written on the platform to perform automated semantic tagging of large corpora. We apply SemTag to a collection of approximately 264 million web pages, and generate approximately 434 million automatically disambiguated semantic tags, published to the web as a label bureau providing metadata regard...

Swarm intelligence algorithms have been succesfully applied to hard optimization problems. Seeker optimization algorithm is one of the latest members of that class of metaheuristics and it has not yet been thorougly researched. Since the early versions of this algorithm were less succesful with multimodal functions, we propose in this paper hybridization of the seeker optimization algorithm wit...

The hide-and-seek game has many interesting aspects for studying cognitive functions in robots and the interactions between mobile robots and humans. Some MOMDP (Mixed Observable Markovian Decision Processes) models and a heuristic-based method are proposed and evaluated as an automated seeker. MOMDPs are used because the hider’s position is not always known (partially observable), and the seek...
