SEMANTIC PARSE TREE KERNEL BASED METHOD AND SYSTEM FOR EXTRACTING RELATIONSHIPS BETWEEN SCIENTIFIC CORE ENTITIES INCLUDING TECHNICAL TERMS AND NAMED ENTITIES

摘要

Disclosed are a semantic syntax tree kernel-based processing system and method for automatic extraction of semantic relationships between core technology. The present invention analyzes a phrase, part-of-speech information, and base phrase information on an input sentence, and performs a pruning on the basis of the analyzed phrase, part-of-speech information and base phrase information, and extracts and extracts a relationship of a phrase of an input sentence. By calculating the syntactic similarity, the lexical semantic similarity, and the semantic syntax tree kernel of the syntax of the input sentence by the relation of the syntax of the sentence, the similarity of the syntax of the input sentence can be accurately calculated.;Semantic syntax tree kernel, syntactic similarity, lexical semantic similarity
