Building a Recommender System for Publications using Vector Space Model and Python:In recent years, it has become very common that we have access to large number of publications on similar or related topics. Recommendation systems for publications are needed to locate appropriate published articles from a large number of publications on the same topic or on similar topics. In this talk, I will describe a recommender system framework for PubMed articles. PubMed is a free search engine that primarily accesses the MEDLINE database of references and abstracts on life-sciences and biomedical topics. The proposed recommender system produces two types of recommendations – i) content-based recommendation and (ii) recommendations based on similarities with other users’ search profiles. The first type of recommendation, viz., content-based recommendation, can efficiently search for material that is similar in context or topic to the input publication. The second mechanism generates recommendations using the search history of users whose search profiles match the current user. The content-based recommendation system uses a Vector Space model in ranking PubMed articles based on the similarity of content items. To implement the second recommendation mechanism, we use python libraries and frameworks. For the second method, we find the profile similarity of users, and recommend additional publications based on the history of the most similar user. In the talk I will present the background and motivation for these recommendation systems, and discuss the implementations of this PubMed recommendation system with example.
