DefIE

About

DefIE is an approach to large-scale Information Extraction (IE) based on a syntactic-semantic analysis of textual definitions. Given a large corpus of definitions DefIE leverages syntactic dependencies to reduce data sparsity, then disambiguates the arguments and content words of the relation strings, and finally exploits the resulting information to organize the acquired relations hierarchically. The output is a high-quality knowledge base consisting of several million automatically acquired semantic relations.
