An approach to the recommendation of scientific articles according to their degree of specificity

This article presents a method for recommending scientific articles taking into consideration their degree of generality or specificity. This approach is based on the idea that less expert people in a specific topic prefer to read more general articles to be introduced into it, while people with more expertise prefer to read more specific articles. Compared to other recommendation techniques that focus on the analysis of user pro files, our proposal is purely based on content analysis. We present two methods for recommending articles, based on Topic Modelling. The first one is based on the divergence of topics given in the documents, while the second uses the similarities that exist between these topics. By using the proposed methods it was possible to determine the degree of specificity of an article, and the results obtained with them overcame those produced by an information retrieval traditional system.
