Embodiment Construction

[0059] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0060] Such as figure 1 Shown is the flowchart of the text semantic understanding method of the embodiment of the present invention, comprising the following steps:

[0061] Step 101, constructing a directed graph grammar network based on the main network-subnet model in advance.

[0062] Different from a large and complex directed graph-grammar network constructed based on grammar rules, in the embodiment of the present invention, the directed graph-grammar network is divided into a main network and a sub-network, that is, the directed graph-grammar network includes A main network and one or more sub-networks, each path of the main network corresponds to a text character or a sub-network identifier. Moreover,...

Abstract

The invention discloses a text semantic comprehension method and system. The method comprises the following steps: constructing a directed graph grammar network based on a main network-sub network mode in advance, wherein the directed graph grammar network comprises a main network and one or more sub networks, and each path of the directed graph grammar network corresponds to a text character or a sub network identifier; acquiring a text to be analyzed; decoding the text based on the directed graph grammar network to obtain a decoded path; acquiring relevant semantics of the decoded path to be taken as the semantic comprehension result. According to the text semantic comprehension method and system, the complexity of the directed graph grammar network can be effectively reduced, the decoding efficiency can be effectively improved, and the memory consumption can be reduced.

Description

technical field [0001] The invention relates to the technical field of natural language processing, in particular to a text semantic understanding method and system. Background technique [0002] As one of the most important directions in the field of artificial intelligence, natural language understanding technology has always been a research hotspot for researchers in related fields. Especially in recent years, with the rapid development of mobile Internet technology and the increasing degree of informatization, the information on the network has also increased exponentially, and human beings have entered the era of big data. People are increasingly eager to allow machines to understand natural language, so as to efficiently analyze and obtain valuable information from massive amounts of data. [0003] The traditional semantic understanding system mainly uses grammar to define several sentence input sets. When the input text is in these sets, the understanding is successf...
