Information extraction method and related equipment

Abstract

The embodiment of the invention discloses an information extraction method and related equipment. The method comprises the steps: firstly carrying out the word segmentation of a retrieval request whenthe retrieval request inputted by a user is detected, and obtaining a plurality of segmented words; determining a dictionary index of a dictionary to which each segmented word in the plurality of segmented words belongs, and determining an recognition extraction rule quoting the dictionary according to the dictionary index; determining a rule template corresponding to the retrieval request according to the recognition extraction rule; and finally, extracting slot position information in the retrieval request according to the rule template. Wherein both the recognition and extraction rule andthe rule template can be visually configured through a Web end management tool, so that by adopting the embodiment of the invention, the development cost of a search engine can be saved, and the iterative updating efficiency of a product is improved.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to an information extraction method and related equipment. Background technique [0002] With the development of the Internet age, users can search for any desired information through search engines. In order to improve the user's search experience and allow users to obtain target information as quickly and accurately as possible, in the prior art, on the one hand, a search method based on a traditional search engine is adopted. The main idea is to index the service capabilities in the form of text first, then recall and sort the words in the text in combination with the existing information recognition and extraction capabilities of the search engine, and then search the users according to the results of the retrieval recall. Request (Query) to extract slot information. On the other hand, the method of customized development based on service category is ado...

AI Technical Summary

Problems solved by technology

However, in the process of adapting to the identification and extraction of new service intentions, whether it is based on traditional search engines or customized development will consume high development costs, any new service requires developers to intervene to carry out corresponding development and testing , the iteration cycle is long and consumes a lot of manpower
