Embodiment Construction

[0019] The implementation method of using the inverted file method in speech input, machine translation, search engine, etc. will be described below. There are slight differences in the three aspects, but the principle is the same. Comprehend the Chinese phonetic alphabet as the phonetic symbols of Chinese, then other languages ​​can also refer to implementation.

[0020] 1. Establish an S database of reference sentence patterns (including word collocations, phrases, and words, the same below) in a certain language, give the sentence pattern number n, and count the number k of characters contained in the reference sentence patterns and word collocations.

[0021] In voice input, speed and accuracy must be weighed, so the reference sentence pattern should be appropriate. The following is the pattern of the voice input reference sentence pattern database:

[0022] serial number

pinyin string

k

Abstract

This invention relates to reference shape and word technique based on reference shape and word division technique, which comprises the following steps: firstly establishing certain language reference sentence database to give sentence code n for statistical sentence type composed of character number k; then establishing inverse row file composed of characters to list all reference sentences codes n composed of the characters to inverse reference sentences.

Description

technical field [0001] The invention is a word segmentation technology based on reference sentence shapes and word collocations, which can be used in speech input, machine translation, search engines and the like. Background technique [0002] Speech input, machine translation, and search engines all need word segmentation. What attracts more attention is that improving the word segmentation accuracy of pinyin strings has become the key to improving the level of Chinese speech input. The algorithms for automatic word segmentation of Chinese pinyin strings mainly include: maximum matching method (MM), least word frequency selection method (FWF) and word-by-word traversal method. According to different scanning directions, the maximum matching method is divided into forward maximum matching method (FMM) and reverse maximum matching method (BMM). The least word segmentation algorithm is based on the principle of the least number of words obtained after segmentation, which is ...
