WITH THE PROLIFERATION OF EPORTFOLIOS and their organizational uses in higher education, it is important for educators and other relevant stakeholders to understand the student perspective. The way students view and use ePortfolios are revealing elements to aid educators in the successful integration of ePortfolio systems. This research describes the development of the Electronic Portfolio Stud...

This paper describes a demonstration of the Discovery Hub exploratory search system. The demonstration focuses on the exploration of topics through several perspectives.

In trying to understand Exploratory Search, the community has focused on users who are working towards an information need, but who are unclear of their goal, technology, or domain of information. Our recent research, however, suggests that this definition misses perhaps the most exploratory search scenario of all scenarios where the goal is not information-oriented.

As information becomes more ubiquitous and the demands that searchers have on search systems grow, there is a need to support search behaviors beyond simple lookup. Information seeking is the process or activity of attempting to obtain information in both human and technological contexts.

In multiclass semi-supervised learning (SSL), it is sometimes the case that the number of classes present in the data is not known, and hence no labeled examples are provided for some classes. In this paper we present variants of well-known semi-supervised multiclass learning methods that are robust when the data contains an unknown number of classes. In particular, we present an “exploratory” ...

We also need instruments to explore the student-supervisor relationship. The present study investigated postgraduate research students’ and resear...
