SEMANTIC SYNTAX TREE KERNEL-BASED PROCESSING SYSTEM AND METHOD FOR AUTOMATICALLY EXTRACTING SEMANTIC CORRELATIONS BETWEEN SCIENTIFIC AND TECHNOLOGICAL CORE ENTITIES

摘要

Disclosed are a semantic syntax tree kernel-based processing system and method for automatically extracting semantic correlations between scientific and technological core entities. According to the present invention, the syntax, part-of-speech information, and base-noun phrase information on input sentences are analyzed; branching is performed on the basis of the analyzed syntax, part-of-speech information, and base-noun phrase information to extract syntax relations between the input sentences; and the syntactic similarity, lexical semantic similarity, and a semantic syntax tree kernel of the syntaxes of the input sentences are calculated using the extracted syntax relations of the sentences to extract syntactic similarities from the input sentences, in order to accurately calculate the similarity of two sentences.
