Abstract

The invention provides a semantic analysis method and device based on sentence rewriting. The method includes rewriting an original sentence to obtain multiple fresh sentences; analyzing the logical expression for generating each fresh sentence through a semantic analysis device; computing grades of logical expressions through a joint model, and selecting the logical expression of the largest grade. According to the method, the sentences can be reanalyzed by sentence writing, semantic analysis can be further performed through the logical expressions matching with natural language sentences, and the accuracy and the robustness are improved.

Description

technical field [0001] The invention relates to the technical field of semantic analysis, in particular to a semantic analysis method and device based on sentence rewriting. Background technique [0002] In recent years, the construction of intelligent information services, such as dialogue robots, question-answering robots, college entrance examination robots, service industry robots, etc., has become a common hotspot in both industry and academia. Intelligent information services require robots to be able to understand human language, including questions and instructions raised by humans. Therefore, how to parse natural language sentences into machine-executable formal representations is the key to realizing intelligent information services, also known as semantic analysis. [0003] Existing semantic analyzers form the final logical expression according to vocabulary and grammar, where vocabulary is a predicate that maps natural language words to ontology; grammar is resp...
