Extraction of Semantic Relationships from Academic Papers using Syntactic Patterns

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, we propose a method to extract semantic relations from concepts and citation in the descriptions of related work. Specifically, we examined (i) topic-paper relations between research topics and reference papers and (ii) method-purpose relations between research topics. We 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.
