In this paper we explore the potential of combining the principle of polyrepresentation with document clustering. Our idea is discussed and evaluated for polyrepresentation of information needs as wells as for document-based polyrepresentation where bibliographic information is used as representation. The main idea is to present the user with the highly ranked polyrepresentative clusters to sup...

The purpose of the present study was to explore, in greater detail, lack of time as a barrier for faculty interested in pursuing education scholarship. METHODS In 2004, as part of a cros...

A new design method for frontier contexts is given a classroom assessment. The method adds the formal consideration of the design context to traditional customer needs assessment. Testing under both controlled and classroom conditions shows the new method is extremely effective, easy to use and well received by students. Implementation at three US schools has shown positive results signifying b...

State-of-the-art Question Answering (QA) systems are very sensitive to variations in the phrasing of an information need. Finding the preferred language for such a need is a valuable task. We investigate that claim by adopting a simple MTbased paraphrasing technique and evaluating QA system performance on paraphrased questions. We found a potential increase of 35% in MRR with respect to the ori...

In the field of personalized systems big role is granted to the adaptive elearning environments. The task of these systems is very important and complicated. With their participation the learner gains exactly the knowledge he needs most, and the system adapts to user needs, expectations and his individual features. In this kind of systems information about learner is saved in the learner model ...

Human–information interaction (HII) for simple information and for complex information is different because people’s goals and information needs differ between the two cases. With complex information, comprehension comes from understanding the relationships and interactions within the information and factors outside of a design team’s control. Yet, a design team must consider all these within a...
