Embodiment Construction

[0047] The embodiment of the present invention discloses a method and device for semantic analysis of natural language. The core invention is that when the received natural language corresponds to at least two semantic meanings in the preset database, according to the historical analysis results, determine the The purpose of describing the semantics of natural language is to make the parsed semantics closer to the user's intention.

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Abstract

The invention provides a method and device for a semantic analysis of a natural language. When a received natural language corresponds to at least two lexemes in a preset data base, a lexeme of the natural language is determined according to a history analytic result. In other words, the history analytic result serves as reference, and the lexeme of a current natural language is analyzed. Generally, the use habit of a user has continuity. Therefore, the purpose of current operation of the user can be reflected through the history analytic result. Therefore, when the natural language corresponds to more than one lexeme, instead of only depending on the preset data base to determine the analytic result, the method and device for the semantic analysis of the natural language can deduce the purpose of the user. Therefore, accuracy of the analysis of the natural language can be improved.

Description

technical field [0001] The invention relates to the field of information processing, in particular to a semantic analysis method and device for natural language. Background technique [0002] In order to improve the efficiency of human-computer interaction, voice recognition-based interaction methods or devices (such as voice assistants) are more and more widely used. Usually, after receiving the voice input by the user, the voice assistant converts the voice into text, and then processes the text data. Parse to determine the semantics of the speech. For example, the voice assistant receives the voice "what's the weather in Beijing tomorrow" input by the user, converts it into text data, and then analyzes the text data to determine the semantics of the voice as querying the weather, the time is tomorrow, and the city is Beijing. Furthermore, after determining the semantics of the voice, the voice assistant can call a third-party application interface, for example, call a Ch...
