Embodiment Construction

[0021] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] The flow process of a search engine dynamic abstract extraction method of the present invention is as follows: figure 1 shown, including the following steps:

[0023] Step s101, acquiring query words input by the user.

[0024] Step s102, intercept candidate abstract paragraphs according to the query words. First, start from the position of the query word in the text and extend to both sides; then according to the forward threshold, the end punctuation set or the end of the previous paragraph, the starting position of the candidate paragraph is obtained, and the position of the query word in the text is extended to When the length of the preceding extension is gr...

Abstract

The invention discloses a method for extracting a dynamic summary of searching engine, the method comprises: acquiring an enquiry word inputted by a user: intercepting a summary candidate paragraph according to the enquiry word; acquiring a paragraph weight value of the candidate paragraph; selecting the candidate paragraph with highest paragraph weight value and preset numbers and combining the selected candidate paragraphs to generate the summary. The invention can intercept the summary candidate paragraph with the user enquiry word as a center, select the candidate paragraph based on the paragraph weight value and combine the selected candidate paragraphs to generate the summary, thereby improving the consistency between the correlativity of the summary and the user enquiry and the correlativity of the original document and the user enquiry.

Description

technical field [0001] The invention relates to the technical field of search engines, in particular to a method for extracting dynamic summaries of search engines. Background technique [0002] In today's rich network of information, in order to quickly and accurately find the required information, search engines have emerged as the times require and have become an important tool for modern networks. Although modern search engines provide more accurate results sorting, there are often some top results that are not what users need. In this case, first, search engines provide services based on full-text indexing technology. As long as the documents contain query Words will be returned, so it is very likely that there are documents that are not relevant to the user's query needs. The second is because the query words may not fully reflect the user's intentions. Therefore, users will judge the value of the link by reading the summary. Then the quality of the abstract directly...
