Taxonomies are the backbone of many structured, semantic knowledge resources. Recent works for extracting taxonomic relations from text focused on collect- ing lexical-syntactic patterns to extract the taxonomic relations by matching the pat- terns to text. These approaches, however, often show low coverage due to the lack of contextual analysis across sentences. To address this issue, we propose a novel ap- proach that collectively utilizes contextual information of terms in syntactic struc- tures such that if the set of contexts of a term includes most of contexts of an- other term, a subsumption relation be- tween the two terms is inferred. We ap- ply this method to the task of taxonomy construction from scratch, where we intro- duce another novel graph-based algorithm for taxonomic str...
