The present invention proposes a method and system for extracting public opinion information based on matrix calculation. The method includes: grabbing website information on the Internet, and establishing an information source matrix, wherein the information source matrix includes information base type information, information base information, and site information. Eight parts: information, sub-site information, information source statistics information, information base authority information, basic attribute information, and article field information; establish a word segmentation matrix and a rule matrix, and obtain the information source matrix, the word segmentation matrix, and the rule matrix respectively The weight and candidate level of the user input the user keyword, select the industry to which the user keyword belongs through the word segmentation matrix, and calculate the comprehensive score according to the weight and the candidate level to complete the public opinion analysis. The present invention does not need to establish an emotional thesaurus, captures data in multiple dimensions in real time, establishes an information source matrix, a word segmentation matrix, and a rule matrix. The three matrices are associated to achieve a dynamic balance, and the words queried by users can be accurately searched, with an accuracy rate of over 95%.
