REPRESENTATION, ANALYSIS, AND EXTRACTION OF KNOWLEDGE FROM UNSTRUCTURED NATURAL LANGUAGE TEXTS

摘要

This article overviews means of description logics for representing knowledge contained in natural language texts and a classification of description logics by constructors of concepts and roles. It also considers basic conceptions of temporal description logics. An approach to the construction of systems for analyzing natural language texts based on problems of parts-of-speech tagging, dependency parsing, and coreference resolution is described. Examples of using natural language knowledge bases to solve applied problems are given, in particular, those of checking the integrity of a text and revealing contradictions.
