The click time relevant with the click of searcher is to import the received time from the click of searcher.According to another embodiment of the invention, relevantly with the click time of searcher can be used At All Other Times.For example, can use searcher in fact will click the time of input client computer.
The information that is stored on the cookie file in the searcher terminal is obtained by Internet search server 104, and wherein 104 visits of Internet search server are stored in the cookie file 102 in the client terminal 101.In the present invention, cookie file 102 can be used to multiple use.This will be described in detail with reference to other embodiment.
The relevant URL information of the search terms of clicking with searcher can obtain by consulting search database, because it is stored in the search database (not shown) relevant with search engine server 104.URL information can be the domain name of the webserver or the information that comprises domain name, catalogue and filename.For example, http://www.naver.com is identical with http://www.naver.com/download, because they are the www.naver.com in view of domain name, but has different URL.In the present invention, use URL and for the purpose of explaining, be illustrated to the embodiment of domain name.Yet the present invention has covered all embodiment, and wherein, if having a different catalogue (because they comprised that domain name, catalogue and filename are whole) although its domain name of URL is identical, URL is considered to different search termses.Should be appreciated that in addition that in the present invention URL information comprises all embodiment according to this instructions.
In addition, except above-mentioned parameter, in spirit of the present invention, other parameter that is used to detect invalid clicks also can be used to detect invalid clicks.
The parameter 302 of mentioned kind is imported into parameter input unit 304.These parameters are stored in again in the log store unit 305.According to the present invention, the example that is stored in the daily record in the log store unit is as shown in Fig. 5,7 and 10.In these accompanying drawings, the daily record that includes only a part of parameter is shown to be used for explanation.Yet, according to another embodiment of the invention, comprise that the daily record of all or part of parameter 302 can be stored in the log store unit 305.
According to one embodiment of present invention, log store unit 305 is stored therein about following at least two daily record: the relevant information of the web browser of the network address under the IP address of searcher terminal, searcher terminal, the search relevant, searcher, the click time relevant with click with search result web page, be stored in the searcher terminal cookie file information and with search terms relevant URL information.According to a preferred embodiment of the present invention, log store unit 305 is stored one therein about following at least one daily record: the relevant information of the web browser of the network address under the IP address of searcher terminal, the searcher terminal, the search relevant, searcher, the click time relevant with click with search result web page, be stored in the searcher terminal cookie file information and with search terms relevant URL information.
Invalid clicks pattern storage unit 306 store therein one with following at least two a pair of relevant invalid clicks model or rule: the relevant information of the web browser of the network address under the IP address of searcher terminal, searcher terminal, the search relevant, searcher, the click time relevant with click with search result web page, be stored in the searcher terminal cookie file information and with search terms relevant URL information.For example, consistent each other rule or model can be stored in the invalid clicks model storage unit 306 in the IP address of searcher terminal and the URL information relevant with the search terms click input in 10 minutes.Similarly, rule that is stored in invalid clicks model storage unit 306 that is used for definite invalid clicks or the like can be stored with the form of file, and this document uses the scheduled instruction according to pre-defined rule.Perhaps, under the situation of above-mentioned rule or model, it can be stored with the form of program so that it is determined is an invalid clicks.
Invalid clicks decision unit 309 determines based on the invalid clicks model of storage in stored log in the log store unit 305 and the invalid clicks model storage unit 306 whether searcher is clicked is invalid clicks.
Invalid clicks is reported keeper 303 report and point hit the preassigned consistent click of unit 308 to internet search engine, and it is disabled to click and determines that unit 309 is definite invalid.According to one embodiment of present invention, invalid clicks report unit 308 reports that to the keeper of internet search engine all are disabled click decision unit 309 and are defined as invalid click.In this case, preassigned is to be disabled to click to determine that unit 309 is defined as all invalid clicks.According to another embodiment of the invention, indicate whether to be stored in each rule or model that stores in the invalid clicks model storage unit 306 to the field of keeper's 303 reports corresponding to the situation of rule or model.In this case, under the situation of rule that must be notified corresponding to keeper 303, invalid clicks report unit 308 reports to keeper 303 with it.
Invalid clicks authentication unit 307 allows keepers 303 to determine unit 309 to be defined as invalid click to change over effective click being disabled to click.Because invalid clicks authentication unit 307 can change over effective click to the click that is decided to be invalid clicks by mistake, so invalid clicks can be determined more accurately.
Fig. 4 is a method flow diagram that detects invalid clicks according to the embodiment of the invention.
Page identifier corresponding to the search result web page that produces is acquired (step 403).When producing search result web page, just produce a page identifier.Page identifier is an identifier that is used to discern search result web page.Therefore, if identical searcher then all distributes a new page identifier by repeatedly import identical search in the search window of Internet search server 104 at every turn.Similarly, if ＂ reload (reloading) ＂ in the web browser of searcher click display of search results webpage, then Internet search server 104 distributes a new page identifier to search result web page, because the searching request grouping is sent to Internet search server 104 from client terminal 101.It is possible that different page identifiers is assigned at first sight identical search result web page.Yet if new searching request is received from client terminal 101, search result web page is produced at that time again.Thereby the search result web page that is different from previous search result web page can be provided.
In step 404, Internet search server 104 receives a click that is included in the search terms in the search result web page from searcher.Be received if click, then Internet search server 104 hyperlink that allows to be used for search terms connects Internet search server 104, allow Internet search server 104 to carry out necessary processing, allow the website of client terminal visit then corresponding to this search terms.For example, at http://www.naver.com/abc/*http: //www.invalidclick.com/ is prepared as under the situation corresponding to the search terms hyperlink of ＂ http//www.invalidclick.com/ ＂, if searcher is clicked this search terms, then search is allowed to be called with visit the search server of http://www.naver.com.Search server allows client terminal to visit http://www.invalidclick.com according to the URL that is positioned at the hyperlink rear side.
In step 406, if other in page identifier and site identifier and the scheduled time slot clicked relevant page identifier and site identifier unanimity, the equipment that then is used to detect invalid clicks determines that click is invalid.
Fig. 5 has shown the journal file according to the example of the embodiment of the invention.The embodiment of Fig. 4 will illustrate with reference to figure 5.
According to the present invention, whenever the click that receives a search terms from the user, page identifier 509 and site identifier 510 just are stored in the journal file 500.Reference numeral 501 to 508 is pointed out the daily record of stored each click input.
Cheating device access the Internet search server 104 is to ask a search.Internet search server 104 produces search result web page and produces a page identifier ＂ nCe249sisnO ＂ corresponding to search result web page.The cheating device is constantly clicked a specific search terms that is included in the search result web page.Even in case the specific search term in the search result web page that is produced is constantly clicked, page identifier can not produced again yet.Thereby page identifier has kept identical value.
Thereby in the click input journal in scheduled time slot, daily record 501, daily record 502 and the daily record 504 of determining to have identical page identifier and identical site identifier are invalid clicks.According to one embodiment of present invention, determine that in the consistent daily record is an invalid clicks, then remaining daily record is an invalid clicks.
The cheating device can upgrade search result web page by the ＂ reload ＂ that clicks in the web browser.In this case, page identifier is reallocated and is daily record 505 about the daily record of page identifier.Thereafter, the cheating device is clicked the situation of identical search term corresponding to daily record 506.
Therefore,, click identical search terms (under the situation of daily record 506) then if the cheating device is clicked ＂ reloads ＂ according to this embodiment, then it not to be determined be an invalid clicks.Similarly, be used for determining that ＂ reload ＂ is that the method for the situation of invalid clicks will be illustrated at the following example with reference to figure 6.
Fig. 6 a and 6b are method flow diagrams that detects invalid clicks according to the embodiment of the invention.
The equipment that is used for definite invalid clicks determines whether the session cookie file is stored in the client terminal 101 (step 603) of request search.Step 603 is processed to obtain a Session ID to step 611.
If determine that the session cookie file is not stored in the client terminal 101, be used for then determining that the equipment of invalid clicks produces a new Session ID (step 604).In step 605, comprise that the session cookie file of Session ID is stored in the client terminal 101.Also be stored in the session cookie file update time of Session ID.Be stored in update time in the session cookie file (step 609).
Be stored in step 602 in the client terminal 101 if determine the session cookie file, the equipment that then is used for determining invalid clicks determines to comprise that final updating time of Session ID of session cookie file is whether in scheduled time slot (step 606).
As the definite result in the step 606, if the final updating time that is included in the Session ID in the session cookie file in scheduled time slot, is used for then determining that the equipment of invalid clicks extracts a Session ID (step 607) that is included in the session cookie file.
As the definite result in the step 606,, be used for then determining that the equipment of invalid clicks produces a new Session ID (step 608) if comprise the final updating time that does not have the Session ID in the session cookie file not in scheduled time slot.The Session ID that is included in the session cookie file upgrades (step 610) with the Session ID of creating again.Be stored in the session cookie file (step 611) update time of Session ID.
If Session ID and site identifier and click relevant Session ID and site identifier unanimity with other in scheduled time slot, the equipment that then is used to detect invalid clicks determines that this click is invalid clicks (step 614).
Fig. 7 has shown the journal file according to the example of the embodiment of the invention.
In this embodiment, whenever the click that receives a search terms from the user, the update time 711 of click time 710, Session ID, Session ID 712 and site identifier 713 are stored in the journal file 700.Reference numeral 701 to 708 is pointed out to click the input stored log corresponding to each.
Cheating device access the Internet search server 104 is to ask a searching request.Internet search server 104 produces a search result web page.Internet search server 104 receives a click that is included in the search terms that included in the search result web page.
The cheating device is clicked identical search terms in identical result of page searching.Internet search server 104 determines whether the session cookie file is stored in the client terminal 101.Because the session cookie file of above-mentioned generation has been stored in the client terminal 101,104 visits of Internet search server are stored in the session cookie file in the client terminal 101.The session cookie file is stored the final updating time of a Session ID and Session ID therein.In this embodiment, Session ID ＂ xigw9492 ＂ and update time ＂ 10:50:14 ＂ be stored in the session cookie file.
Thereby, determine that daily record 702 is invalid clicks, because it has Session ID and the site identifier identical with daily record 701.
According to this embodiment, the cheating device is clicked the situation of identical search terms after scheduled time slot, because a Session ID is produced, be an invalid clicks so it is determined.
Similarly, determine to determine that based on invalid clicks such situation may be an invalid clicks according to another embodiment of the invention, promptly make click in the scheduled time slot that begins in the last click time from identical search term.This will be illustrated simply.
Be received from searcher if click, determine then whether the session cookie file is stored in the terminal.Be stored in the terminal if determine the session cookie file, then determine from click time of the search terms of searcher whether in the scheduled time slot that begins from the last click time relevant with Session ID.
The interior Session ID of session cookie file is acquired and the time of click at last upgraded with the click time of search terms if the click time of determining search terms in scheduled time slot, then is included in.
If the click time of determining search terms, then new Session ID is produced with renewal was included in Session ID in the session cookie file not in scheduled time slot.In addition, the time of click at last upgraded with the click time of search terms.
For example in Fig. 7, come from existence under the situation of a plurality of clicks of identical search term of same client machine terminal, if determine from last click over and done with 5 seconds situation be effective, it is effectively that then relevant with daily record 704 click is determined, because made " 10:50:31 " behind 13 seconds of its last click time ＂ 10:50:18 ＂ formerly.
According to a preferred embodiment of the invention, time reference decides according to the testing goal of invalid clicks.
Fig. 8 is a method flow diagram that produces Session ID according to the embodiment of the invention.
Session ID must be distributed uniquely so that it can distinguish and must be difficult to be copied or forge with other Session ID.Under the situation that Session ID is only distributed uniquely, there is a possibility, in fact the device of promptly practising fraud may produce a Session ID and then Session ID is stored among the session cookie, perhaps may increase click volume wrongly with a program, this program is driven constantly to be clicked search terms and changes Session ID simultaneously.
Be used for to be used to and produce one subsequently with the page identifier that is illustrated, site identifier, terminal identifier or the like according to the method that this embodiment produces Session ID.
Fig. 9 is a method flow diagram that detects invalid clicks according to the embodiment of the invention.
In step 904, if relevant client computer IP address and site customers machine IP address unanimity are clicked with site identifier and interior other of scheduled time slot in client computer IP address, the equipment that then is used for the search invalid click determines that this click is invalid.
Figure 10 has shown the journal file according to the example of the embodiment of the invention.
In this embodiment, whenever the click that receives a search terms from the user, click time 1010, client computer IP address 1011 and site identifier 1012 just are stored in the journal file 1000.Reference numeral 1001 to 1009 is specified institute's stored log of clicking input corresponding to each.
If identical client terminal is constantly clicked identical search terms, be repeated in scheduled time slot if then click, it is very high then should to click invalid possibility.Yet, so often situation, promptly the user of same client machine terminal clicks identical search terms after the long duration.In other words, have a trend, promptly the user often visits its very interested website.If the user constantly visits a website at short notice, then be difficult to it is regarded as a common click.Thereby it is an invalid clicks that this situation is determined.For example, if time standard is 5 minutes, it is invalid clicks that daily record 1002, daily record 1004 and the daily record 1005 that then has client computer IP address identical with daily record 1001 and an identical site identifier is determined.Determine that in about 20 minutes the click relevant with clicked daily record 1009 is effective click.
If determine invalid clicks, there is the careful point of some needs so based on client computer IP address.Use in the situation of acting server or IP gateway at client terminal, have a danger, even the cheating device is clicked the search terms identical with other client terminal, it also may be confirmed as an invalid clicks.Therefore, preferably, this embodiment is with an embodiment combined structure that uses other parameter such as Session ID.
On the contrary, have such a case, the client computer IP address of promptly clicking the client terminal of identical search term is different, and their network address is identical.This is corresponding to such a case, and promptly the several people constantly attempts coming inequitable click one place or clicking identical search terms with a program, and changes their source IP address simultaneously.In this case, if to click the network address of the client terminal of identical search term be identical and other situation (for example, in the catalogue under search terms, click volume is greater than the situation of average click volume) be satisfied, then this can be determined be an invalid clicks.
