Embodiment Construction

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0033] Structured information is information managed by databases that we usually come into contact with, including records of production, business, transactions, and customer information. Unstructured information, the technical term is content, which covers a wider range of information and can be divided into: operational content: such as contracts, invoices, letters and procurement records; departmental content: such as document processing, electronic forms, briefing files and emails ; Web content: information in formats such as HTML and XML; multimedia content: such as sound, video, graphics, etc.

[0034] Massive information appearing on the Internet can be roughly divided into three type...

Abstract

This application discloses a method, device, and system for extracting associations of Chinese entities. According to the relationship properties of relational words in Chinese texts, the target implementing entity and target receiving entity related to the relational words in the text are extracted, and then according to the relationship The target implementing entity and the target receiving entity corresponding to the word and the relational word generate the Chinese entity association relationship corresponding to the relational word in the text. The technical solution provided by the embodiment of the present application divides the unstructured Chinese text into different words and sentences according to different relational properties, and further reduces the location range of the target implementing entity and target receiving entity of each relational word, so as to improve the search efficiency. Accuracy and search speed, reduce the amount of calculation. In addition, the technical solution in the embodiment of the present application also uses division rules on the Chinese grammatical level to largely filter out some redundant erroneous relative words and erroneous entities, improving the accuracy of extracting relative words and entities .

Description

technical field [0001] The present application relates to the technical field of natural language processing, in particular to a method, device and system for extracting associations of Chinese entities. Background technique [0002] With the rapid development of the Internet and the rapid improvement of the economic level, if you want to take the lead when formulating corporate strategies, you must have a keen sense of smell, grasp more relevant information, and grasp as much as possible between enterprises and enterprises. The relationship between enterprises and individuals can assist decision makers to make the most reasonable plan. [0003] Existing enterprise association identification technologies generally rely more on standardized and structured collected data. However, this method has great limitations, such as slow update of text information sources, high delay, etc., and the structuring of data will take more time to screen and organize information, and it may n...
