Combining Formal Concept Analysis and semantic information for building ontological structures from texts : an exploratory study

Proceedings of the Eighth International Conference on Language Resources and Evaluation (LREC 2012)

Abstract

This work studies conceptual structures based on the Formal Concept Analysis method. We build these structures based on lexico-semantic information extracted from texts, among which we highlight the semantic roles. In our research, we propose ways to include semantic roles in concepts produced by this formal method. We analyze the contribution of semantic roles and verb classes in the composition of these concepts through structural measures. In these studies, we use the Penn Treebank Sample and SemLink 1.1 corpora, both in English.
