Recommendation-based browsing assistance for corporate knowledge portals

ABSTRACT

The management of knowledge, i.e. knowing what is known and the ability to exploit it is a burning issue for most organizations. Though knowledge management has a strong social perspective, information technology supports knowledge management strategies by providing tools that store codified knowledge and allow its retrieval. The value of knowledge management derives from the wide use of the stored knowledge, its annotation and refinement as well as its application in business practices. We support this issue of information browsing and retrieval by adapting and applying recommendation technology to reduce access barriers towards corporate knowledge portals. For this purpose we exploit domain heuristics to improve collaborative filtering techniques in order to cope with the problem of low numbers of users the knowledge portals have.
