With reference to Fig. 3 A, find that the method for concept type website may further comprise the steps:
Step S302a uses the concept type document recognition algorithm of invention 1 that collections of web pages is handled to obtain the concept type web pages set; And
Step S304a, the URI that concept type web pages is gathered carries out statistical treatment.
In step 302a; The element of collections of web pages is single web document; Set is identical or approximate identical with the collections of web pages that user search need be inquired about, and is indifferent to the Data Source of collections of web pages, but requires each webpage to keep the unique identification of original URI as webpage.
Wherein, step S304a comprises: add up the concept type web pages URI sum under each website domain name successively, record URI sum surpasses the sum of concept type web pages URI under website domain name (like A.com) and this domain name of a certain predetermined threshold N; To the website that selects; Do further statistics with the URI sum of statistics under subprime directory; If the URI sum under a certain catalogue still exceeds predetermined threshold value N,, and replace the higher level's domain name (A.com) that has write down then with the URI (like A.com/Z/) that writes down this catalogue; Catalogue analysis does not so step by step perhaps have the next stage sub-directory to analyze up to the sub-directory that does not exceed threshold value N.
Find that the non-concept type catalogue in the concept type website is through on the basis of finding the concept type website, the distribution situation of the non-concept type page realizes in the set of continuation concept of analysis type catalogue.With reference to Fig. 3 B, find that the step of the non-concept type catalogue in the concept type website comprises:
Step S302b, the method for utilizing website to mate, the concept type catalogue set that generates among the use step S304a and the URI of the webpage in the collections of web pages mate, and mate successful adding " concept type web pages set *";
Step S304b is in " concept type web pages set *" in, carry out and invent 1 concept type document recognition algorithm, the webpage that is identified as non-concept type document is added non-concept type web pages set; And
Step S306b; URI (A.com/Z) with in the set of concept type catalogue is the basis; The URI that adds up non-concept type web pages set backing wire page or leaf distribution situation at different levels below the concept type catalogue; If the ratio of non-concept type web pages surpasses a certain predetermined threshold K under certain one-level catalogue, then write down this grade catalogue and stop this catalogue is done further analysis.
Fig. 3 C shows the concept type catalogue set of the step generation that utilizes among Fig. 3 B and the non-concept type catalogue set that the step among Fig. 3 B generates, and uses the concept type document analysis algorithm (hereinafter to be referred as method 2) of simplification, analyzes the method for identification concept type web pages.
Step S302c uses the concept type Website Hosting to mate the URI that imports webpage successively.Wherein, if coupling concept type catalogue set failure, then nonrecognition is a concept type web pages; If coupling concept type catalogue is gathered successfully, continue to use non-concept type catalogue set to carry out similar coupling; Gather successfully if mate non-concept type catalogue, then nonrecognition is a concept type web pages; If mate non-concept type catalogue set failure, then this page be identified as the concept type page, and extract notional word.
The instance of step S302c is following:
By the step among Fig. 3 A obtain the set of concept type catalogue XXX: //A.com/Z, XXX: //A.com/Y, XXX: //B.com/W}
By the step among Fig. 3 B obtain the set of non-concept type catalogue XXX: //A.com/Z/M, XXX: //A.com/Y/N/P, XXX: //B.com/W/Q}
Then the step among Fig. 3 C is respectively for the judged result of following URI:
XXX: //the A.com/Z/H/1.html concept type (coupling XXX: //A.com/Z)
XXX: //the non-concept type of A.com/Z/M/2.html (coupling XXX: //A.com/Z and coupling XXX: //A.com/Z/M)
XXX: //the A.com/Y/N/R/3.html concept type (coupling XXX: //A.com/Y)
XXX: //the non-concept type of B.com/4.html
XXX: //the non-concept type of C.com/5.html
In three steps of Fig. 3 A, Fig. 3 B and Fig. 3 C, the step among the step among Fig. 3 A and Fig. 3 B is the distribution situation of coming concept of analysis type website as the basis with 1 the method for inventing.Yet the method that it also can not utilize invention 1 promptly, can replace to other effective concept type document recognition algorithms with " concept type recognizer ".Step among Fig. 3 C is the application that identification concept type website distributes, and the statistics of utilizing the concept type website to distribute is only discerned specific data as concept type web pages.On the basis that concept type website distribution results is analyzed out in advance, recognition efficiency is very high.Because concept type web pages has the intensive characteristics that distribute in the internet; Utilize concept type website DISTRIBUTION RECOGNITION concept type document can effectively remedy the defective of recognizer, though can lose the data of part website, the concept type total number of documents that identifies has the lifting of certain scale; And because the inner concept type DATA DISTRIBUTION of website is intensive; For the user, the confidence level of Search Results also is improved, and effect can be superior to independent concepts type document recognition.
Fig. 4 obtains the method flow diagram of classification concept type website and similar notional word according to the utilization of the embodiment of the invention the 4th embodiment notional word of presorting.
Because the concept type document has concentrated character in some professional websites distribution can utilize some known particular category notional words, the step in Fig. 3 C is mated after analyzing the concept type document and extracting notional word.After mating successfully, write down the concept type catalogue set that this concept type document hits in identifying, as the corresponding concept type catalogue set of this classification notional word.In instance in Fig. 3 C, if XXX: //notional word of A.com/Z/H/1.html extraction and the notional word coupling in the classification first, then record concept type catalogue XXX in the concept type catalogue of classification first correspondence is gathered: //A.com/Z.
With reference to Fig. 4, may further comprise the steps according to the utilization of the embodiment of the invention the 4th embodiment method that notional word obtains classification concept type website and similar notional word of presorting:
Step S402 after the concept type catalogue set that obtains some classification, adds up each concept type catalogue corresponding class information; Under the fully comprehensive situation of the classification concept speech that is used to mate that provides in advance, if the only corresponding a kind of or limited a few kind of certain concept type catalogue perhaps exceeds predetermined threshold Q with the ratio that speech a certain or limited a few kind couplings account for all classificating words that provide in advance of this catalogue coupling; Simultaneously, exceed predetermined threshold P, then can think with notional word sums a certain or limited a few kind couplings; Document under this concept type catalogue; All belong to this corresponding a kind of or limited a few kind, and the notional word that document extracted under this concept type catalogue also belongs to this a kind of or limited a few kind basically; Promptly; Utilize the notional word category distribution under the concept type catalogue, can analyze possible classification concept type catalogue, and further excavate similar notional word.
The present invention utilizes the distribution characteristics of concept type web pages; Filter out some and comprise the seldom website of the concept type page, and make that distribution is comparatively concentrated, a fairly large number of website of the concept type page is selected out as the concept type catalogue than the website that comprises less concept type web pages more easily.Like this, just can not be identified as the concept type page by the page that confidence level is lower through the present invention, thereby can represent better Search Results.
