example 1

[0059] In the process of semantic understanding of the text to be parsed "How much taller is Zhang San than Li Si?", the slot dictionary associated with the text to be parsed is first obtained.

[0060] Wherein, the associated slot dictionary may include candidate words belonging to subject, predicate and comp_words parts of speech. Specifically, the candidate words belonging to the subject part of speech are {Zhang San, Li Si, Wang Wu, Zhao Liu}, the candidate words belonging to the predicate part of speech are {weight, height, age}, and the candidate words belonging to the comp_words part of speech are {How big, How small, how tall, how low, how fat, how thin}.

[0061] Based on the associated slot dictionary, determine the target semantic element rule that matches the text to be parsed as [subject] to [subject][predicate][comp_words].

[0062] Use the target semantic element rule to analyze the parsed text, and get the words belonging to the subject part of speech in the t...

Abstract

The embodiment of the invention discloses a semantic processing method and device, electronic equipment and a medium, and relates to the technical field of knowledge maps. According to the specific implementation scheme, a target semantic element rule matched with a to-be-analyzed text is determined, and the to-be-analyzed text is analyzed by adopting the target semantic element rule to obtain a semantic element analysis result; a target structured rule associated with the target semantic element rule is adopted, and a semantic tree is generated according to a semantic element analysis result;and based on the semantic tree, semantic understanding is performed on the to-be-analyzed text. According to the embodiment of the invention, the analysis efficiency and accuracy of complex problemsin the to-be-analyzed text are effectively improved.

Description

technical field [0001] The present application relates to the field of data processing, specifically to the technical field of knowledge graphs, and in particular to a semantic processing method, device, electronic equipment and media. Background technique [0002] Natural language processing studies the effective communication between humans and computers using natural language, correctly understanding the semantic information of natural language, so that people can use their most accustomed language to use computers without spending a lot of time and energy on learning Various computer languages ​​that are not very natural and habitual, so that natural language processing technology can also be used to further understand the mechanism of human language ability and intelligence. [0003] However, it is very difficult to realize accurate understanding of natural language semantics. In the process of understanding natural language semantics, there is a problem of low accuracy...
