Embodiment Construction

[0029] The basic process of the embodiment scheme of the present invention is as figure 1 As shown, the following basic steps are included:

[0030] Step 101: Formulate identification rules for pattern words, named entity words such as person names, place names, and organization names, and corresponding large-grained and small-grained distinguishing information.

[0031] Among them, the identification rules for pattern words include:

[0032] Granularity information is added to the recognition rules, that is, granularity distinction points. Then use a deterministic finite state automaton (Deterministic Finite Automaton, DFA) to express the recognition rules, so that in the process of word segmentation, the finite state automaton can be used to identify pattern words that meet the rules. In this way, at the time of final output, the above-mentioned DFA can be used to divide the pattern words according to the large and small granularity requirements of the user, and the patter...

Abstract

Disclosed is a device and method for large and small particle size segmentation of chinese text, comprising the steps of setting segmentation mode of large and small particle size, treating the chinese text with corresponding segmentation mode in accordance with the input particle size and outputting the segmented chinese text. According to actual needs, the invention can segment text by corresponding particle size and satisfy a requirement of different subsequent treatments of Chinese text.

Description

technical field [0001] The invention relates to the technical field of text information automatic processing, in particular to a method and device for realizing large and small granularity segmentation of Chinese text. Background technique [0002] Since the Chinese text is based on single characters, that is, a piece of Chinese text is composed of single characters, the words that express the meaning of the text do not have explicit separation marks between words like English, so in order to perform semantic analysis on Chinese texts, the first The task of is to add a word boundary marker to each word in the text, so that the formed word string can reflect the original meaning of the sentence. [0003] The existing Chinese word segmentation methods can generally meet the basic requirements of Chinese word segmentation, but Chinese word segmentation is the most basic analysis and processing of text. Based on this processing, there are many other subsequent text processing op...
