Problems solved by technology

At present, there are many methods for evaluating the relevance of web pages, and most of them focus on factors that can reflect customer needs or intentions in a certain aspect, such as the matching degree of search terms or sentences, and the relationship between web page links. However, only using such retrieval processing methods The obtained web pages often contain many complicated factors, and it is difficult to accurately provide search resources that are closely connected with the actual needs of customers
Therefore, there is no relatively complete and mature evaluation method that can fully reflect the value of web pages.

Embodiment Construction

[0051] The present invention will be further described below in conjunction with the accompanying drawings.

[0052] like figure 1 , the Rank synthesizer 1 is a preset mathematical model. An example of a specific Rank synthesis algorithm is given below.

[0053] Equivalence relationship: Because the basic factors are too different, we normalize it; through a large number of statistical and human sociological characteristics, we determine:

[0054] Factor 1 Value = Factor 2 Value = . . . = Factor 6 Value.

[0055] That is to say, they are considered to have equivalent effects on Rank under a certain value.

[0056] Rank=(∑ user reading factor equivalence + ∑ similar content quantity factor equivalence + ∑ web page association / recommendation value equivalence) * author value factor value * website value factor value * occurrence time factor

[0057] Example: The graph of the time decay function f(x)=1-e^(-1 / x) is as attached image 3 shown.

[0058] Among them, the newer t...

Abstract

The invention provides a value evaluation method for network resource, by which the value measurement of webpage resources to a searching user can be effectively evaluated, thus web resources which are high-quality and really meet the user's intention are priorly provided for the user, the user browse and lookup time is reduced, and the searching efficiency is improved. Furthermore, the invention discloses a method for applying the value evaluation method for network resource to network search engine. According to the value evaluation method, when the network is searched, searched network resources are provided with more accurate weights by which worthless or little-value network resources can be removed, and resources more relevant to a user's real intention can be provided for the user priorly.

Description

technical field [0001] The present invention relates to information retrieval technology, in particular to a method for searching and summarizing by using a specific index of related targets——PeopleRank and its application in the field of search engines. Background technique [0002] At present, search engines generally input one or a group of keywords or text fragments through the user, and after retrieval processing, a considerable number of web pages containing the keyword or text fragment or closely related to it are returned to the user for users to browse and check. required information. [0003] However, the number of webpages on the Internet is extremely huge, and it is still growing at an unprecedented rate. If the traditional search processing mode is still followed, that is, search engine operators simply analyze and process the astonishing amount of webpage resources they have collected. Classify and reserve, then the number of relevant web pages searched accord...
