Problems solved by technology

[0003] No matter whether the processing method of these comments is obtained through simple statistical analysis or through manual reading, scientific results cannot be obtained.
The statistical analysis of the former can only obtain the frequency of occurrence of related words, and such a single method cannot obtain the original meaning of the original comment
The latter will consume huge manpower and material resources, and the feasibility of this method will decrease exponentially with the increase of online comment text

Abstract

The invention provides a knowledge base construction method based on short text comments, belongs to the field of natural language processing, and aims at providing related world knowledge for short text analysis so as to overcome the defects of existing short text analysis. High combination of short text analysis statistics and analysis with grammatical rules is achieved. By constructing a knowledge base of the related comments, relevant characteristic words, characteristic word matching, evaluation words and grading, and degree adverbs and grading in the related comment field are obtained. By constructing the knowledge base of the related comments, in short text analysis, the comment knowledge database can be used for conducting public opinion analysis, emotion analysis and information extraction, and accuracy and efficiency of related work are improved.

Description

technical field [0001] The invention belongs to the field of natural language processing, and more specifically relates to a method for constructing a relevant knowledge base for short text reviews. Background technique [0002] Currently, various online forums, shopping websites, and review websites are flooded with a large amount of review information. These comments contain a large number of colloquial and grammatical errors. These colloquial and grammatical errors bring a lot of confusion and errors to text analysis. [0003] No matter whether the processing method of these comment analysis is obtained through simple statistical analysis, or through manual reading, scientific results cannot be obtained. The former statistical analysis can only obtain the frequency of occurrence of related words, and such a single method cannot obtain the original meaning of the original comment. The latter will consume huge manpower and material resources, and the feasibility of this ...
