Embodiment Construction

[0072] 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.

[0073] Such as figure 2 As shown, it is a flowchart of a method for realizing text semantic fault-tolerant understanding in an embodiment of the present invention, including the following steps:

[0074] Step 201, obtain the text string to be parsed.

[0075] Step 202: Decode the text string based on a pre-built fault-tolerant directed graph grammar network to obtain a decoding path.

[0076] Different from the traditional precise directed graph grammar network, in the embodiment of the present invention, the text string is decoded based on the fault-tolerant directed graph grammar network. The fault-tolerant directed graph-grammar network includes not only precise paths without fault-tolerant special marks, ...

Abstract

The invention discloses a method and system for realizing text semantics fault-tolerant understanding. The method comprises the following steps: acquiring text character strings to be resolved; decoding the text character strings based on a pre-constructed fault-tolerant directed graph grammar network to obtain decoding paths; if the decoding paths are accurately-matched paths, acquiring semantics information corresponding to the decoding paths, wherein the accurately-matched paths indicate that the matching paths do not include fault-tolerant special marks defined in the fault-tolerant directed graph grammar network; otherwise, performing fuzzy processing on each decoding path based on a preset fuzzy dictionary to obtain an optimal decoding path; and acquiring semantics information corresponding to the optimal decoding path. Through adoption of the method and system, fault-tolerant deep natural language understanding of sentences, phrases and the like can be realized, and the robustness and accuracy of a natural language understanding system are improved.

Description

technical field [0001] The invention relates to the technical field of natural language processing, in particular to a method and system for realizing fault-tolerant understanding of text semantics. Background technique [0002] The development of artificial intelligence technology has a long history, and natural language understanding technology, one of the most important directions in the field of artificial intelligence, has always been a research hotspot. It can be said that it has always been a dream of human beings to allow machines to understand natural language. Especially with the advent of the mobile Internet era, human beings have entered the era of big data. Efficiently analyzing and obtaining valuable information from massive data is an inevitable trend of future technological development. [0003] Traditional semantic understanding is mainly suitable for semantic analysis of accurate text strings, especially natural language understanding based on grammatical r...
