Abstract

The invention provides a decision search engine implementation method based on a finite state automaton, which comprises the following steps: S1, obtaining related documents through a search engine according to problems searched by a user to form a document set; s2, extracting sentiment phrases in the document set based on the document sentiment phrase mode of the dictionary; s3, establishing an emotional automaton based on a dictionary; s4, calculating the sentiment intensity of the document sentiment phrase mode based on the sentiment automaton, and obtaining the sentiment intensity analysisresult of each document; and S5, obtaining an auxiliary decision result of the problem searched by the user based on the document emotion intensity analysis result. According to the technical scheme,data analysis and processing can be carried out on the retrieval result while the retrieval result related to the user is provided, and the evaluation result or the emotion state of a certain entityand the quantitative analysis of the emotion intensity degree are provided for the user, so that the user is assisted in making a decision on the searched problem.

Description

technical field [0001] The invention relates to the technical field of search engines, in particular to a method for implementing a decision-making search engine based on a finite state automaton. Background technique [0002] Realize search engine optimization technology based on decision tree classification algorithm (CN201710046903) Determine the core keywords according to the business of the enterprise, search for the data items corresponding to the keywords, the processing speed is faster, it has good use value, and can quickly improve the keyword ranking, so as to achieve the ideal website optimization goals. [0003] Information recommendation method and device, search engine system (CN201811347764) receives search keywords input by users, determines recommended media associated with the search keywords, and recommended information associated with the recommended media; the recommended media is non-advertising Subject media; displaying the recommended media as search...
