Embodiment 1

[0017] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] like figure 1 As shown, a search engine evaluation method includes the following steps:

[0019] Step 101. Calculate the current domain ontology according to the domain ontology graph used to represent the weight and weight relationship between the current keyword and other keywords and the web page ontology graph used to represent the weight and weight relationship between the current keyword and other keywords in the current web page The web page relevance of a certain keyword in the current web page.

[0020] The method can be as follows: construct a domain ontology graph according to the selected keywords, the domain ontology graph includes the weight relationship between the current keyword and other keywords in the current domain; search the keyword through a search engine, and select the returned Construct a webpage ontology gra...

Embodiment 2

[0026] For ease of understanding, the following will combine the attached Figure 2-3 The specific implementation manners of the embodiments of the present invention are further described.

[0027] like figure 2 As shown, a search engine evaluation method includes the following steps:

[0028] Step 201, capturing keywords. Capture keywords from professional directory websites, such as Wikipedia, Baidu Encyclopedia, and ODP, and classify the captured keywords according to fields to form a keyword thesaurus, such as music, sports, etc. Generally speaking, using the captured keywords in professional directory websites to build domain-related inquiry word thesaurus can improve the accuracy of web page relevance evaluation, thereby improving the accuracy of the system.

[0029] Step 202, select keywords, and construct a domain ontology graph according to the selected keywords.

[0030] First select a keyword, establish a keyword set according to the field type of the current k...

Abstract

The invention discloses an evaluating method for a search engine, comprising the steps that the webpage relevance of a certain keyword of the current field body in the current webpage is computed according to a field body graph used for indicating the weights and the weight relationship of the current keyword and other keywords, and a webpage graph used for indicating the weights and the weight relationship of the current keyword and other keywords in the current webpage; the summation of webpage relevance of webpages returned by the search engine according to the current keyword is computed, and the grade of the current search engine in the field involving the current keyword is obtained. By adopting the evaluating method for the search engine, the search engine can be evaluated in a concise, accurate and quick manner.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a search engine evaluation method. Background technique [0002] The rapid development and widespread popularization of the Internet have made it easy for people to obtain information from the Internet, but the explosive growth of network information has greatly increased the difficulty for people to obtain valuable information accurately and quickly. Since the corpus size, index freshness and corpus repetition of each search engine are different, the results returned by the search engines relative to the same keyword are quite different. [0003] When users need to search for keywords in a certain field and expect to find the information they need accurately, they need to compare the advantages and disadvantages of various search engines in the current field to choose the most suitable search engine for information acquisition. [0004] In the prior art, when eval...
