Method and apparatus for extracting and structuring domain terms

摘要

A method of automatically categorizing terms extracted from a text corpus is comprised of identifying lexical atoms in a text corpus as terms. The identified terms are extracted based on a relation that exists between the terms. A weight is assigned to each relation. A graphical representation of the relationships among terms is constructed by using terms as vertices and relations as weighted links between the vertices. A vertex score is calculated for each of the vertices of the graph. Each term is categorized based on its vertex score. The graphical representation may be revised based on its structure and/or the calculated vertex scores. Because of the rules governing abstracts, this abstract should not be used to construe the claims.
