An Expertise Recommender Using Web Mining

Purnima Chandrasekaran, Anupam Joshi, Michelle Shu Yang, and Ramya Ramakrishnan, University of Maryland, Baltimore County, USA

In this paper we explore techniques to mine web pages of scientists to extract information regarding their expertise, build expertise chains and referral webs, and semi automatically combine this information with directory information services to create a recommender system (Resnick and Varian 1997) that permits query by expertise. We experimented with some existing techniques that have been reported in research literature in recent past (including our own prior work), and adapted them as needed. We developed software tools to capture and use this information.
