Article Recommendation Based on Citation Relations


With the tremendous amount of research publications, finding relevant articles/papers for researchers to fulfill their information need becomes a significant problem. The major objective of our work is that given a particular paper, how to effectively find a set of relevant papers from an existing citation graph. Existing approaches do not take into account link semantics in the relevance computation and treat links in the citation graph as equally important. In this talk, we first present a model called Local Relation Strength by incorporating citation relations to measure the dependency between cited and citing papers. To capture the relevance strength between any two papers in the whole citation graph, another model called Global Relation Strength (GRS) is next proposed, and is evaluated on a real-world publication data set. The experimental results show that our GRS model has a promising improvement over the baseline techniques.
