Abstract

Due to the enormous volume of unstructured information available on the Web and inside organization, finding an answer to the knowledge need in a short time is difficult. For this reason, beside Search Engines which don’t consider users individual characteristics, RECOMMENDER SYSTEMS were created which use user’s previous activities and other individual characteristics to help users find needed knowledge. RECOMMENDER SYSTEMS usage is increasing every day. Expert finder systems also by introducing expert people instead of recommending information to users have provided this facility for users to ask their questions form experts. Having relation with experts not only causes information transition, but also with transferring experiences and inception causes knowledge transition. In this paper we used university professors academic resume as expert people profile and then proposed a new EXPERT FINDING model that recommends experts to users query. We used Term Correlation Matrix, VECTOR SPACE MODEL and PageRank algorithm and proposed a new hybrid model which outperforms conventional methods. This model can be used in internet environment, organizations and universities that experts have resume dataset.
