Evaluation of keyphrase extraction algorithm and tiling process for a document/resource recommender within e-learning environments

The research presented in this paper is an examination of the applicability of IUI techniques in an online e-learning environment. In particular we make use of user modeling techniques, information retrieval and extraction mechanisms and collaborative filtering methods. The domains of e-learning, web-based training and instruction and intelligent tutoring systems provide a challenging environment due to the large and diverse user population it entails. The overall system concentrates on utilizing a user modeling system to filter results as part of a collaborative document recommendation system. The goal of such a system is to actively seek out and recommend documents that will either encourage the users to expand their knowledge of a given topic or reinforce the knowledge which they already have. The system aims to recommend these documents in a non-intrusive manner with minimal user inconvenience, and attempts to do so by utilizing the Key Extraction Algorithm and automatically extracting queries, searching the web and filtering the search results. Users are encouraged to provide feedback about the resources and links they have viewed.
