An intelligent retrieval method and device based on symbol recognition

Abstract

The invention discloses an intelligent retrieval method and an intelligent retrieval device based on symbol recognition. The method comprises the following steps of: A) inputting a search term on a material search network platform; B) analyzing the influence of symbols in the search words on semantics; C) judging whether the symbol is reserved or not, and if yes, executing the step D); Otherwise,executing the step F); D) the material searching network platform adopts different word segmentation strategies to perform word segmentation on the searching word according to the contents before andafter the symbol to obtain a corresponding word segmentation result; E) the material searching network platform performs searching in a retrieval library by using the word segmentation result obtainedthrough analysis, returns a searching result which most accords with expectation to a user, and executes a step G); And F) removing the symbols and executing the step D), and G) ending. The intelligent retrieval method and device based on symbol recognition have the following beneficial effects that an accurate search result can be obtained.

Description

technical field [0001] The invention relates to the field of search engines, in particular to an intelligent retrieval method and device based on symbol recognition. Background technique [0002] Traditional search engines will filter some symbols in the search terms. In general, the filtering process will not affect the search results. However, in the plastics industry, some product names, categories, and manufacturer names contain some symbols. If Filtering according to general search engines will result in inaccurate search results. Therefore, the traditional search engine's symbolic processing of search words during the search process will lead to inaccurate results. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an intelligent search method and device based on symbol recognition that can obtain accurate search results in view of the above-mentioned defects of the prior art. [0004] The technical solution...
