Search history record also can be user behavior form.Further, such as, a user searches for based on search sequence " Sina ", and opens the Search Results that page link is " http://www.sina.com ".This Search Results can be defined as optimal search result according to the search history record of this user behavior form by browser.
Each user can identify based on the identification information of user, the register account number of such as user.Such as, or each user also can identify based on the identification information of subscriber equipment, subscriber equipment sequence number etc.
Browser at least can by following 2 kinds of modes obtain each search sequence respectively with the corresponding relation of one or more optimal search result:
1) browser from other equipment obtain each search sequence respectively with the corresponding relation of one or more optimal search result.
Wherein, other equipment described include but not limited to the network equipments such as search engine and other subscriber equipmenies such as mobile phone, ipad.
Such as, the determined each search sequence of search history record of the user that it can preserve based on high in the clouds by search engine sends to browser with the corresponding relation of one or more optimal search result respectively, and correspondingly, browser obtains this corresponding relation.
2) browser is based on the search history record of user, in at least one search sequence of this user of local record input each respectively with the corresponding relation of one or more optimal search result, wherein in each Search Results of each optimal search result corresponding to its corresponding search sequence, the Search Results of this user's historical viewings is determined.
At this, browser can analyze the historical search record of user, with the corresponding relation of local record search sequence and optimal search result.Such as, in each Search Results corresponding to search sequence " Sina ", the Search Results of user's historical viewings is " http://www.sina.com.cn/ ", then this Search Results can be confirmed as optimal search result.Further, the corresponding relation of browser local record search sequence " Sina " and optimal search result " http://www.sina.com.cn/ ".
In step s 2, browser obtains the search sequence of this user input.
At this, the present invention can be only the optimal search result that in aforementioned corresponding relation, any one search sequence determines its correspondence.For clearly demonstrating, the search sequence in aforementioned corresponding relation can be called as effective search sequence.
If the search sequence that user inputs belongs to the effective search sequence in aforementioned corresponding relation, then this search sequence of this user input is effective search sequence, and browser directly can obtain the search sequence of this user input.
If the search sequence that user inputs does not belong to the effective search sequence in aforementioned corresponding relation, browser then carries out pre-service to obtain corresponding effective search sequence to the search sequence of user's input, and using search sequence that the search sequence after process inputs as this user.
Wherein, described pre-service includes but not limited to lexicographic tree matching treatment, regular expression verification process etc.
One or more search sequence all can correspond to an effective search sequence, thus forms the lexicographic tree of this effective search sequence.Described lexicographic tree matching treatment specifically comprises determines whether the search sequence that user inputs matches with an effective search sequence, if coupling, effective search sequence that the search sequence that user inputs mates is the search sequence after process, and this effective search sequence can as the search sequence of user's input.
Effective search sequence can to there being one or more checking regular expression.Whether the search sequence that checking regular expression may be used for authentication of users input corresponds to an effective search sequence, if corresponding, the effective search sequence corresponding to search sequence that user inputs is the search sequence after process, and this effective search sequence can as the search sequence of user's input.
Such as, the search sequence of user's initial input is " Division A League Matches of French Football are amassed ", browser can carry out pre-service, using the search sequence inputted as user by the search sequence " Division A League Matches of French Football integration " after process by the mode such as lexicographic tree matching treatment, regular expression verification process to " Division A League Matches of French Football are amassed ".
In step s3, the search sequence that browser inputs according to this user, determines target search result from corresponding optimal search result.
Wherein, described target search result means in optimal search result to be supplied to the Search Results of user.
At this, the search sequence that browser inputs according to user, by inquiring about the corresponding relation of previous searches sequence and optimal search result, determines target search result from the optimal search result corresponding to search sequence.
Wherein, if search sequence only corresponds to an optimal search result, then this unique optimal search result can be confirmed as target search result.
If search sequence corresponds to multiple optimal search result, these optimal search result all can be confirmed as target search result, or wherein part optimal search result can be confirmed as target search result.Such as, browser can the some optimal search result of Stochastic choice as target search result.And for example, preceding for ranking optimal search result can be defined as target search result by browser.
In step s 4 which, browser directly provides described target search result to this user.
At this, providing of target search result should be interpreted broadly, and it both can for be supplied to user by page link, also can for the content page pointed by page link is supplied to user.Those skilled in the art will be understood that, under different application scene, target search result can be provided to user by rights.
Fig. 2 illustrates method flow diagram in accordance with a preferred embodiment of the present invention, and it specifically illustrates and a kind ofly provides the process of target search result for user.Particularly, in step S1 ', browser obtain each search sequence respectively with the corresponding relation of one or more optimal search result, wherein at least partly search sequence determined by the search history record of a user at least partly in each self-corresponding optimal search result; In step S2 ', browser obtains the search sequence of this user input; In step S3 ', the weight of each optimal search result corresponding to the search sequence that browser inputs based on this user, determines target search result; In step S4 ', browser directly provides target search result to this user.
Wherein, step S1 ', the step S2 ' of Fig. 2, step S4 ' and the corresponding step step S1 in Fig. 1, step S2, step S4 are same or similar, therefore do not repeat them here, and are contained in this by way of reference.Below mainly will specifically describe step S3 '.
In step S3 ', the weight of each optimal search result corresponding to the search sequence that browser inputs based on this user, determines target search result.
At this, in the corresponding relation of search sequence and optimal search result, part optimal search result has a weight separately.
Wherein, weight is for representing the preferred rank of optimal search result.Typically, the weight of an optimal search result is higher, and this optimal search result is more better than other optimal search result.
The weight of optimal search result can be determined based on any one mode following:
1) weight of optimal search result is determined the number of visits of corresponding optimal search result based on user.
At this, browser such as directly can determine the weight of optimal search result according to the number of visits of user to corresponding optimal search result.
Such as, user is 5 times to the number of visits of an optimal search result, then the weight of this optimal search result is 5.
2) weight of optimal search result is determined the nearest browsing time of corresponding optimal search result based on user.
At this, browser such as can determine the weight of optimal search result based on the corresponding relation of user to the nearest browsing time of corresponding optimal search result and the weight of optimal search result.
Such as, user is today nearest browsing time to an optimal search result, then the weight of this optimal search result is 10.User was yesterday nearest browsing time to an optimal search result, then the weight of this optimal search result is 9.User was the day before yesterday nearest browsing time to an optimal search result, then the weight of this optimal search result is 8.By that analogy.
3) weight of optimal search result is browsed duration to determine to corresponding optimal search result based on user.
At this, browser such as can determine the weight of optimal search result based on the corresponding relation browsing the weight of duration and optimal search result of user to corresponding optimal search result.
Such as, user browses duration more than 10 minutes to an optimal search result, then the weight of this optimal search result is 10.The browse duration of user to an optimal search result is 9 to 10 minutes, then the weight of this optimal search result is 9.The browse duration of user to an optimal search result is 8 to 9 minutes, then the weight of this optimal search result is 8.By that analogy.
4) weight of optimal search result is determined based on the combination of any in aforementioned 3 weight parameter two or whole three.
At this, each weight parameter aforementioned can be assigned with a corresponding weight coefficient.Browser can according to preceding sections or all weight parameter and corresponding weight coefficient calculate weighted sum, this weighted sum to be defined as the weight of optimal search result.
Such as, browser can determine the weight of optimal search result based on following formula 1:
Resultweight=viewcount × R viewcount+ recenttime × R recenttime+ viewtime × R viewtimeformula 1
Wherein, viewcount represents the number of visits of user to optimal search result, R viewcountrepresent the weight coefficient of number of visits; Recenttime represents the nearest browsing time of user to optimal search result, R recenttimerepresent the weight coefficient of nearest browsing time; What viewtime represented user's optimal search result browses duration, R viewtimerepresent the weight coefficient browsing duration; Resultweight represents the weight of optimal search result.
Those skilled in the art will be understood that; aforementionedly determine that the mode of the weight of optimal search result is only citing; and should not be regarded as any limitation of the invention; any existing alternate manner or the mode of the weight of determination optimal search result that may occur from now on are as being applicable to the present invention; also within scope should being included in, and this is contained at this with way of reference.
Each search sequence that browser obtains and the corresponding relation of optimal search result further can as shown in the following Table 2:
Table 2
At this, the mode of the weight determination target search result of each optimal search result corresponding to the search sequence that browser inputs based on this user includes but not limited to following 2 kinds:
1) if the weight of at least one exceedes its respective weights threshold value in each optimal search result corresponding to search sequence of user's input, corresponding optimal search result is defined as target search result by browser.
Wherein, weight threshold can be the unified numerical value of an overall situation.Or weight threshold also can carry out different configurations according to the weight parameter of different determination weights.
Such as, as shown in table 2, the weight (weight is " 6 ") of the optimal search result " http://www.sohu.com/ " corresponding to search sequence " Sohu " exceedes its respective weights threshold value (weight threshold is such as " 3 "), and this optimal search result can be defined as target search result by browser.
2) optimal search result the highest for weight is defined as target search result by browser.
Such as, as shown in table 2, the weight of two optimal search result corresponding to search sequence " listing flow process " is respectively 8,4, and optimal search result " http://www.zhihu.com/question/19629831 " the highest for weight can be defined as target search result by browser.
Those skilled in the art will be understood that; determine that the mode of target search result is only citing for aforementioned 2 kinds; and should not be regarded as any limitation of the invention; any existing alternate manner or may occur from now on sets the goal the mode of Search Results really as being applicable to the present invention; also within scope should being included in, and this is contained at this with way of reference.
In table 2, more than one of the optimal search result corresponding to part searches sequence.Those skilled in the art will be understood that the corresponding relation of this search sequence and optimal search result is only citing.According to a preferred embodiment of the present invention, search sequence also only can correspond to an optimal search result that weight is the highest.Correspondingly, this optimal search result directly can be defined as target search result by browser, if or the weight of the highest optimal search result of the weight corresponding to search sequence of user's input exceedes its respective weights threshold value, this optimal search result is defined as target search result by browser.
In addition, if weight exceedes more than one of the optimal search result of its respective weights threshold value, or more than one of the optimal search result that weight is the highest, these optimal search result all can be defined as target search result by browser.Or browser can also the weight of optimal search result corresponding to search sequence, and in conjunction with the different priorities corresponding to weight parameter, determines target search result.
Such as, as shown in table 2, the weight of two optimal search result that search sequence " Sina " is corresponding is 7, but, the weight of optimal search result " http://www.sina.com.cn/ " is determined the number of visits of this optimal search result based on user, and the weight of optimal search result " http://www.weibo.com/ " is determined the duration of browsing of this optimal search result based on user.If the priority of the weight determined according to the number of visits of optimal search result is higher than the priority browsing the weight that duration is determined according to optimal search result, optimal search result " http://www.sina.com.cn/ " can be defined as target search result by browser.
Preferably, at least one default search result is also comprised at least one each self-corresponding optimal search result of institute in each search sequence.If the weight of each optimal search result corresponding to search sequence of user's input does not all exceed its respective weights threshold value, browser selects this default search result to be target search result.
At this, default search result at least can be determined based on following 2 kinds of modes:
1) searching record of default search result Corpus--based Method user is determined.
At this, default search result can the searching record of Corpus--based Method a large number of users be determined.Such as, after a large number of users searches for a search sequence and acquisition comprises the page of multiple Search Results, by page browsing total degree (page access amount that user browses in these Search Results, i.e. PageView, referred to as PV) maximum Search Results can be confirmed as default search result.And for example, after a large number of users searches for a search sequence and acquisition comprises the page of multiple Search Results, total degree (independent user sessions is browsed by the user that user browses in these Search Results, i.e. Unique Visitor, referred to as UV) maximum Search Results can be confirmed as default search result.Wherein, those skilled in the art will be understood that the Search Results that page browsing total degree is maximum is identical with the Search Results possibility that user browses total degree maximum, also may be different.For Search Results, its number of page views is different with the statistical of user's number of visits.Such as, a user browses a Search Results 5 times, and when adding up, the number of page views of this Search Results increases by 5 times, and user's number of visits of this Search Results only increases by 1 time.
2) default search result is determined based on page quality.
At this, page quality can whether complete based on content of pages, whether the page attractive in appearance, the page to user whether friendly, page source whether authority's specialty etc. because usually determining.The Search Results that page quality is the highest can be confirmed as default search result.
At this, each search sequence that browser obtains and the corresponding relation of optimal search result further can as shown in the following Table 3:
Table 3
As shown in table 3, default search the possibility of result is identical with other optimal search result, also may be different.
Such as, if the weight of each optimal search result corresponding to search sequence of user's input does not all exceed its respective weights threshold value, browser selects default search result to be target search result.
As shown in table 3, the weight (weight is " 1 ") of the optimal search result corresponding to search sequence " Division A League Matches of French Football integration " does not exceed the weight threshold (weight threshold is such as " 3 ") of its correspondence, and browser can select default search result " http://soccer.hupu.com/table/France.html " to be target search result.
Preferably, in step S1 ', browser can from other equipment to obtain at least one search sequence each respectively with the corresponding relation of one or more default search result.
