Integrating concept and citation networks on a specific research subject can help researchers focus their own work or use methods described in prior works. In this paper, the authors propose a method to extract semantic relations from concepts and citation in the descriptions of related work. Specifically, they examined topic-paper relations between research topics and reference papers and method-purpose relations between research topics. They also defined 15 lexico-syntactic patterns for the relation extraction. Results of experiments using a manually annotated dataset of 15 papers demonstrated the effectiveness of using the proposed lexico-syntactic patterns.
