specific example

[0077] see Figure 8 , the following is a specific example: including the following steps:

[0078] a) Obtain news articles published in the last month related to specific fields from the Internet as document corpus and store them in the document library; the articles can be obtained from the Internet or other media. Considering the timeliness, it is preferred to obtain it from the Internet. The 1 month here is an example, and you only need to extract time-sensitive articles as needed.

[0079] b) Construct a syntactic pattern in the form of (S, W, N), where S represents the domain tag word, W represents the pattern tag word, and N represents the set of all nouns after the pattern tag word. Schema identifiers include two categories, namely, synonymous schema identifiers and sub-concept schema identifiers:

[0080] 1. Synonymous pattern identifiers (including but not limited to): that is, also called, abbreviated, aliased, or, commonly known

[0081] 2. Sub-concept identifi...

Abstract

The invention provides a document and label word semantic association method and a device thereof.The method comprises the following steps that S100, documents are obtained and serve as a document corpus, wherein the documents belong to the field relevant to label words and have timeliness; S200, a syntactic pattern is constructed, syntactic pattern matching is conducted on the document corpus, and results according with the syntactic pattern are merged to serve as a candidate mention relevant word set C; S300, the candidate mention relevant word set C is filtered through a trained Word2vec pattern, and a mention relevant word set V is obtained; S400, according to mention relevant words and the label words, relevancy degrees of multiple documents and the label words are calculated, and a relevancy degree database of the label words and the documents is constructed.The document and label word semantic association method dynamically constructs semantic association on the basis of the real-time document corpora and does not depend on a synonym base which is static and high in maintenance cost.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for semantically associating documents and tag words. Background technique [0002] Today's Internet generates massive amounts of news information every day, and the ability of individuals to read and understand news information is limited. However, Internet users need to know what events have happened and what events have been discussed on the Internet. For example, financial industry analysts and investors need to consult a large number of Information to understand the current hot events in the industry, in order to know what news related to the hot events. [0003] At present, the more common method of establishing domain tags and document associations is through keyword matching, that is, if the specific tag word appears in the document, the document is considered to be related to the tag. and extract it as a pending document. The problem is that the r...
