Embodiment 1

[0062] The present embodiment provides a method for extracting predicate chunks in a Chinese sentence, such as figure 1 shown, including:

[0063] S1. Carry out word segmentation processing to the Chinese sentence, and obtain a word segmentation unit sequence set composed of all word segmentation units in the Chinese sentence;

[0064] S2. Load the concepts corresponding to the word segmentation unit sequence set, and obtain all the concepts of all the word segmentation units in the Chinese sentence;

[0065] S3. Excluding concurrent classes of dynamic concepts;

[0066] S4. Generate different types of candidate predicate blocks according to the combination of the remaining dynamic concepts and other related concepts;

[0067] S5. Selecting a predicate block of the Chinese sentence from the candidate predicate blocks.

[0068] Specifically, in step S1, the Chinese sentence can be segmented according to the forward maximum word segmentation method using the Chinese stop word...

Embodiment 2

[0160] The present embodiment provides a predicate block extraction system in a Chinese sentence, such as Figure 4 As shown, include: word segmentation unit sequence set acquisition unit 1, concept acquisition unit 2, exclusion unit 3, generation unit 4 and selection unit 5, wherein word segmentation unit sequence set acquisition unit 1 is used to carry out word segmentation processing to Chinese sentences, and obtain the described The word segmentation unit sequence set that all word segmentation units in the Chinese sentence form; Concept acquisition unit 2 is used for loading the concept corresponding to the word segmentation unit sequence set, and obtains all concepts of all word segmentation units in the described Chinese sentence; Exclusion unit 3 is used for The concurrent class of dynamic concepts is excluded; Generating unit 4 is used for generating different types of candidate predicate chunks according to the combination between remaining dynamic concepts and other ...

Abstract

The present invention provides a method and system for extracting predicate blocks in Chinese sentences. By performing word segmentation processing on Chinese sentences, a word segmentation unit sequence set composed of all word segmentation units in the Chinese sentence is obtained; loading the word segmentation unit sequence set corresponds to The concepts of all word segmentation units in the Chinese sentence are obtained; the concurrent classes of dynamic concepts are excluded; according to the combination of remaining dynamic concepts and other related concepts, different types of candidate predicate chunks are generated; from the candidate A predicate block of the Chinese sentence is selected from the predicate blocks. Synthesize various language rules to screen and combine all the concepts of all word segmentation units in Chinese sentences, and select the predicate blocks of Chinese sentences accordingly, which can accurately identify and reduce the misjudgment rate.

Description

technical field [0001] The invention relates to Chinese information processing technology, in particular to a method and system for extracting predicate chunks in Chinese sentences. Background technique [0002] Chinese information processing technology has gone through several stages of word-oriented, grammatical structure-oriented, and phrase-oriented. Now, the focus of Chinese information processing technology has turned to semantic analysis. [0003] HNC is the abbreviation of Hierarchical Network of Concepts (Hierarchical Network of Concepts). HNC theory (Hierarchical Network of Concepts) is a theoretical system about natural language understanding and processing. The HNC theory holds that the essence of natural language understanding is the whole process of activation, expansion, concentration, conversion and storage of concept association contexts. The main point of activation operation is the understanding of sentences; the main point of expansion and condensation ...
