Problems solved by technology

Conventional retrieval methods include information index retrieval and semantic information retrieval. Among them, information index retrieval is based on inverted index, keyword matching, etc., and the results obtained are inaccurate; semantic information retrieval is more accurate, but its data processing capacity, Retrieval is slow

Embodiment Construction

[0042] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0043] like figure 1 As shown, a judgment document information retrieval method, the method includes:

[0044] S100: Obtain the information to be retrieved, and perform semantic-based word splitting on the information to be retrieved.

[0045] Semantic-based word splitting refers to splitting the information to be retrieved into independent words based on the meaning of words. The information to be retrieved can be a part of a judgment document, such as a certain paragraph, a certain sentence, and the judgment result; the information to be retrieved can also be a key par...

Abstract

The invention relates to the technical field of big data, is applied to data retrieval industry, and provides a judgment document information retrieval method and device, computer equipment and a storage medium. According to the whole scheme, a Hash value mode is adopted to compress the to-be-retrieved information and the data in the judgment document database; first-stage positioning is performedaccording to the hash value, a target judgment document set to be selected is searched, the target judgment document is searched in the target judgment document set by adopting a similarity matchingmode in the second stage, the data processing amount is remarkably reduced by adopting a Hash value compression mode, and the high efficiency and accuracy of retrieval are ensured by adopting a Hash value compression and similarity matching mode.

Description

technical field [0001] The present application relates to the technical field of retrieval, in particular to a judgment document information retrieval method, device, computer equipment and storage medium. Background technique [0002] With the development of science and technology, a large amount of data is pouring into people's lives, how to retrieve the required data from the massive data has become a difficult problem. [0003] Take the judgment documents as an example. As time goes by, the accumulated judgment documents are a massive amount of data. How to retrieve the current required information from this massive data is bothering users. Conventional retrieval methods include information index retrieval and semantic information retrieval. Among them, information index retrieval is based on inverted index, keyword matching, etc., and the results obtained are inaccurate; semantic information retrieval is more accurate, but its data processing capacity, Retrieval is slo...
