The present invention is described in further detail below in conjunction with the accompanying drawings.

Fig. 1 is one aspect of the invention for the method flow diagram that is ranked up to resource items.Wherein, according to the present invention Method mainly completed by the collator in computer equipment, the collator include but is not limited to be arranged on computer In equipment and it can realize the device of application module, operating system, the processing controller of the present invention program etc..Wherein, should Computer equipment includes but is not limited to：1) user equipment；2) network equipment.The user equipment include but is not limited to computer, Smart mobile phone, PDA etc.；The network equipment includes but is not limited to single network server, the clothes of multiple webservers composition Device group of being engaged in or the cloud being made up of a large amount of computers or the webserver based on cloud computing (Cloud Computing), wherein, cloud Calculating is one kind of Distributed Calculation, a super virtual computer being made up of the computer collection of a group loose couplings.

In step sl, collator obtains the timeliness related to the list entries according to the list entries from user Information.

Specifically, collator obtains the list entries that other devices or equipment are provided, or, obtain come from user in real time List entries, and obtain according to the list entries age information related to the list entries.Wherein, collator is obtained The mode of the age information related to the list entries includes but is not limited to：

1) collator is inquired about in uprushing keywords database in pre-established user's request according to the list entries, and It regard the Query Result obtained by inquiry as the age information.Wherein, the Query Result includes any one of following：A) it is used for table Show that the keywords database inquiry that can be uprushed in user's request obtains the mark for the keyword that the list entries or the list entries are included Information, for example, " Y ", " 1 " etc.；B) for expression have not been able to user's request uprush keywords database inquiry obtain the list entries Or the identification information of keyword that the list entries is included, for example, " N ", " O " etc..Preferably, in the Query Result also include with It is at least one of lower：A) pass of uprushing in keywords database is uprushed in the user's request that user's request is uprushed obtained by keywords database inquiry Keyword；B) information related to the keyword of uprushing obtained by inquiry, for example, the user's request change of list entries or keyword is strong Degree etc..

2) collator obtains the Aging Characteristic information related to the list entries according to the list entries, using as The age information.Wherein, the Aging Characteristic information includes can be used in related to the list entries and can be used in judging Whether the list entries is the characteristic information with ageing list entries.Preferably, the Aging Characteristic information include but It is not limited to following at least the next item down：

A) the resource items quantity for being retrieved to obtain based on list entries is changed with time information；For example, the resource The quantity information that changes with time includes following information：Wrapped in the resource items for being retrieved to obtain based on the list entries The resource items set up containing 50 resource items set up in preceding 96 to first 120 hours, 48 in preceding 72 to first 96 hours, 127 The individual resource items set up in first 48 hours to first 72 hours, 309 resource items for being set up in preceding 24 to first 48 hours and 1045 resource items for being set up in 24 hours；In another example, retrieved obtained by resource items quantity change with time information The resource information quantity set up in its relative time adjacent segments including the resource information quantity set up in each predetermined amount of time Changing value etc..Preferably, collator passes through the foundation or renewal to the resource items obtained by being retrieved based on list entries Time carries out statistical analysis, is changed with time information to obtain the resource items quantity.

B) number of times that is retrieved for the keyword that list entries and/or list entries are included changes with time information；For example, In each predetermined amount of time or in predetermined point of time, the number of times that is retrieved for the keyword that list entries or list entries are included； In another example, each predetermined amount of time or predetermined point of time are with respect to the list entries or keyword at its time adjacent segments or time point Be retrieved difference of number of times etc..Preferably, the keyword that collator is included based on list entries or list entries is come local Inquired about in storage device, to obtain pre-stored corresponding with list entries or list entries are included keyword be retrieved Number of times changes with time information；Or, collator sends request to other devices or equipment, with obtain with list entries or The corresponding number of times that is retrieved of keyword that list entries is included changes with time information；Or, collator passes through predetermined The number of times that is retrieved of the keyword included in period to list entries or list entries is monitored and counted, to obtain the quilt Retrieval number of times changes with time information.

C) the burst semantic feature information of the list entries obtained based on semantic analysis is carried out to the list entries. Wherein, burst semantic feature information includes burst character keyword and/or burst character semantic structure.For example, burst is semantic special Reference breath includes time-critical words such as " newest, today, this week, nearest, certain year are in such a month, and on such a day ", or including such as " Shake, traffic accident, die, catch fire, cutting people's event, suicide door " etc. accident keyword；In another example, happen suddenly semantic feature structure bag Include the structures such as proper noun+common noun；For another example burst semantic feature information includes " Fukushima earthquake " etc. simultaneously Semantic feature information comprising burst character keyword and burst character semantic structure.Preferably, it is preferable that collator base Inquired about in list entries in local memory device, it is semantic special to obtain pre-stored burst corresponding with list entries Reference ceases；Or, collator sends request to other devices or equipment, semantic special to obtain burst corresponding with list entries Reference ceases；Or, collator carries out semantic analysis to the list entries, to obtain the burst semantic feature letter of the list entries Breath.

3) collator is first inquired about with being somebody's turn to do according to the list entries in keywords database is uprushed in pre-established user's request The relevant keyword of uprushing of list entries；When inquire it is relevant with the list entries uprush keyword when, Query Result is made For the age information；When fail to inquire it is relevant with the list entries uprush keyword when, collator is according to described defeated Enter sequence to obtain the Aging Characteristic information related to the list entries, the step of using as the age information.Wherein, sort Device obtained according to the list entries mode of the Aging Characteristic information related to the list entries with it is foregoing 2) in sequence Device acquisition Aging Characteristic information mode is same or similar, will not be repeated here.

It should be noted that the above-mentioned examples are merely illustrative of the technical solutions of the present invention, rather than to the limit of the present invention System, it should be appreciated by those skilled in the art that list entries of any basis from user is related to the list entries to obtain The implementation of age information, should be included in the scope of the present invention.

Then, in step s 2, whether collator meets predetermined condition according to age information, whether judges list entries With ageing.Wherein, the predetermined condition includes being based on being confirmed as what is obtained with ageing list entries The condition met required for age information；For example, when timeliness packet is included in keywords database is uprushed in pre-established user's request During Query Result obtained by being inquired about, predetermined condition includes including the identification information such as " Y " or " 1 " in Query Result, works as timeliness When information includes Aging Characteristic information, predetermined condition includes condition met required for Aging Characteristic information etc., it is preferable that be based on The pass that the resource items quantity that list entries is retrieved to obtain is included with growth faster, list entries or the list entries of time Keyword be retrieved number of times with the time growth is faster, the burst semantic feature that includes is stronger in burst semantic feature information, then List entries is judged as that the possibility with ageing list entries is higher by collator.

For example, predetermined condition includes including identification information " Y " or " 1 ", in step sl, collator base in Query Result The age information obtained in list entries includes the Query Result for including identification information " Y "；Then collator is believed according to the timeliness Breath meets predetermined condition, judges that list entries has ageing.

In another example, the resource items quantity that predetermined condition includes setting up in any time period is set up with respect in its previous time period Resource items quantity growth rate more than 50%；In step sl, collator obtain based on list entries retrieved come The resource items quantity of acquisition changes with time information including following information：Retrieved to obtain based on the list entries Set up in resource items comprising 50 resource items set up in preceding 96 to first 120 hours, 48 in preceding 72 to first 96 hours Resource items, 127 set up in first 48 hours to first 72 hours resource items, 309 set up in preceding 24 to first 48 hours Resource items and 1045 resource items set up in 24 hours；Then collator analysis resource items quantity changes with time letter Breath, determines growth of the resource items quantity set up in each period with respect to the resource items quantity set up in its previous time period Rate, and according to the resource items quantity relatively preceding 72 set up in first 48 hours to first 72 hours to the resource set up in first 96 hours The growth rate 62.2% of item quantity is more than the first predetermined growth threshold value 50%, judges that list entries has ageing.

For another example predetermined condition includes following two conditions：I) include crucial comprising burst semantic feature in list entries Word；Ii) number of times that is retrieved of list entries and its keyword included is equal with the growth rate of time in any two period More than 100%；In step sl, collator obtains in list entries " earthquake door " and includes burst character keyword " earthquake ", And obtain the number of times that is retrieved for the keyword " earthquake " that list entries " earthquake door " and list entries are included and change with time Information is as shown in table 1 below：

Table 1

Being retrieved for the keyword " earthquake " that then collator is included to list entries " earthquake door " and list entries is secondary Count the information that changes with time to be analyzed, determine list entries and the number of times that is retrieved of its keyword included in any two In period 100% is respectively less than with the growth rate of time；Then collator judges list entries " earthquake door " without ageing.

It should be noted that the above-mentioned examples are merely illustrative of the technical solutions of the present invention, rather than to the limit of the present invention System, it should be appreciated by those skilled in the art that whether any judge list entries according to whether age information meets predetermined condition With ageing implementation, it should be included in the scope of the present invention.

In step s3, when judging that the list entries has ageing, collator is to based on the list entries The resource items for being retrieved to obtain carry out ageing sequence, and the resource items after sequence are supplied into the user.

Wherein, the resource items that collator is obtained to being retrieved based on the list entries carry out ageing sequence, Include but is not limited in the way of the resource items after by sequence are supplied to user：

1) part money is selected in multiple resource items that collator is obtained by being retrieved based on the list entries Source item, and selected resource items are placed in predetermined sorting position, then non-selected resource items are ranked up；Then, arrange Resource items after sequence are supplied to user by sequence device.Wherein, collator can be according to the foundation or renewal of such as resource items The many factors such as time, the clicking rate of resource items, the quality of the resource items of pre-determining, the matching degree of resource items and list entries come Select foregoing a part of resource items.

For example, predetermined sorting position is front three sorting position, collator is retrieved based on the list entries To obtain multiple resource items, and select in the plurality of resource items setup time be shorter than 24 hours and with the matching degree of list entries More than the resource items of predetermined matching degree threshold value, then, collator in selected resource items further by selecting before clicking rate The resource items of three, and the resource items of the clicking rate front three are placed in front three sequence according to the order of clicking rate from high to low Position；Then, collator is ranked up using prior art to remaining resource items, and by identified front three resource items And other resource items after sequence are supplied to user.

2) part money is selected in multiple resource items that collator is obtained by being retrieved based on the list entries Source item, and processing is weighted to selected resource items, it is ranked up with the result after being handled according to weighting, and will Resource items after sequence are supplied to user.This will be with reference to embodiment illustrated in fig. 2 by way of being ranked up weighting processing In be described in detail, will not be described here.

It should be noted that the above-mentioned examples are merely illustrative of the technical solutions of the present invention, rather than to the limit of the present invention System, it should be appreciated by those skilled in the art that it is any when judging that the list entries has ageing, to based on the input sequence Arrange the resource items for being retrieved to obtain and carry out ageing sequence, the resource items after sequence are supplied to the realization of the user Mode, should be included in the scope of the present invention.

It should be further stated that, when judging that the list entries has ageing, collator or other devices The resource items obtained to being retrieved based on the list entries carry out the sequence processing of prior art, by the money after sequence Source item is supplied to the user；Or, when judging that the list entries has ageing, collator does not perform any behaviour Make.

One of it is preferred that, resource items quantity and the required money showed that collator shows required for Source item sorting position, determines the resource items corresponding to the resource items sorting position that the needs show.For example, user equipment is to search Engine sends the list entries for being inquired about, then the collator in search engine is according to the disposable institute's energy of the user equipment The resource items quantity enough presented is 10, is selected in the resource items obtained based on the list entries, and before determination 10 sorting positions corresponding resource items feed back to user equipment, the resource items offer of preceding 10 so that user equipment will sort To user；Then, asked when user equipment sends page turning to search engine, search engine based on the list entries again by being obtained Selected in the resource items obtained, and determine 11 to 20 corresponding resource items of sequence to feed back to user equipment, so that user The resource items of the sequence 11 to 20 are supplied to user by equipment.

One of it is preferred that, after collator is ranked up to the resource items obtained based on list entries, according to Need to be presented to the resource items sorting position of user, the resource items for carrying out selected section sorting position are supplied to user.For example, user Equipment sends the list entries for being inquired about to search engine, then the collator in search engine is to based on list entries After being ranked up the resource items that obtain, the rule that the resource items after 10 sequences are once provided based on acquiescence, before sequence The resource items of 10 are supplied to user equipment, so that user equipment will sort, the resource items of first 10 are supplied to user；Then, when User equipment search engine sends the request for providing the resource items of page 3, then search engine is according to the corresponding resource items of page 3 21 to 30 resource items, the resource items of the 21st to 30 of sorting are supplied to user equipment, so that user equipment will sort the The resource items of the resource items of 21 to 30 are supplied to user.

As one of preferred scheme of the present invention, uprushed keyword to being contained in pre-established user's request in the present invention At least one keyword of uprushing in storehouse performs following steps S41 (not shown), step S42 (not shown) and step respectively S43 (not shown).

In step S41, collator obtains one or more users to based on currently processed uprush keyword or bag List entries containing the currently processed keyword of uprushing is come the click information of the resource items after the sequence that obtains.Preferably, should Click information is included based on the currently processed list entries uprushed keyword or include the currently processed keyword of uprushing Come the click volume and/or clicking rate of each resource items after the sequence that obtains.

Specifically, collator obtains the click information of other devices offer；Or, collator passed through in the scheduled time Click behavior of the user based on the resource items after foregoing sequence is monitored and counted in section, to obtain click information.

Then, in step S42, collator judges the pass of uprushing according to the click information of gained in abovementioned steps S41 The whether ageing mistake of keyword.

Wherein, collator judge uprush keyword it is whether ageing cross mode include but is not limited to：

1) collator is according to being designated to predetermined sorting position or be chosen to be weighted processing in abovementioned steps S3 Resource items clicking rate or click volume, and combine other resource items clicking rate or click volume between, to obtain judgement evaluation of estimate； And judge whether evaluation of estimate is more than or less than the first preset judgment threshold value according to this, to judge that currently processed keyword of uprushing is No ageing mistake.

For example, the user that collator is obtained in step S41 is to based on keyword of uprushing, " May, CPI " carried out retrieval institute The click volume of 7 resource items obtained is as shown in table 2 below：

Resource items	Click volume
		Resource items A	1230
Resource items B	234
		Resource items C	123
Resource items D	467
		Resource items E	986
Resource items F	209
		Resource items G	78

Table 2

Wherein, resource items A and E are the resource items for being designated to predetermined sorting position, and resource items D is to be chosen to be weighted The resource items of processing, then collator the click volume of resource items A, D and E click volume average value and resource items B, C, F and G is put down The difference 733 of average, which is used as, judges evaluation of estimate, and according to evaluation of estimate is judged more than the first preset judgment threshold value 500, judges current The ageing non-mistake of keyword of uprushing of processing.

2) collator is shorter than the resource items of the first scheduled time threshold value according to foundation or renewal time in each resource items Click information, and combine each resource items in set up or renewal time be longer than the second scheduled time threshold value resource items click Information, to obtain judgement evaluation of estimate；And judge whether evaluation of estimate is more than or less than the second preset judgment threshold value according to this, to judge The currently processed whether ageing mistake of keyword of uprushing.

For example, collator by each resource items set up or renewal time be shorter than 3 days resource items click information with Set up or renewal time be longer than 90 days resource items click information ratio as judging evaluation of estimate, and according to judgement evaluation Whether value is more than or less than the second preset judgment threshold value, to judge the currently processed whether ageing mistake of keyword of uprushing.

It should be noted that the above-mentioned examples are merely illustrative of the technical solutions of the present invention, rather than to the limit of the present invention System, it should be appreciated by those skilled in the art that it is any according to click information, judge the whether ageing realization crossed of keyword of uprushing Mode, should be included in the scope of the present invention.

In step S43, when judging the ageing mistake of the keyword of uprushing, collator is uprushed pass in the user's request The keyword of uprushing is deleted in keyword storehouse.

Preferably, when judging the ageing non-mistake of the keyword of uprushing, collator does not perform operation to the keyword of uprushing.

One of preferred scheme as the present embodiment, the step S2 further comprises step S21 (not shown) and step Rapid S22 (not shown).

In the step s 21, whether collator meets predetermined condition according to the Aging Characteristic information, judges the input It is ageing whether sequence has.Wherein, whether collator meets predetermined condition according to Aging Characteristic information to judge to input sequence Whether row there is ageing step to be described in detail in abovementioned steps S2, will not be repeated here.

In step S22, when judging that the list entries has ageing, collator by the list entries and/ Or keyword in the list entries adds the user's request and uprushed in keywords database.Preferably, collator will also be with The list entries corresponding Aging Characteristic information addition user's request is uprushed in keywords database；It is highly preferred that collator is also The information that will be obtained based on Aging Characteristic information, for example, the number of times that is retrieved of resource items quantity or list entries is with the time Growth rate etc., the addition user's request is uprushed in keywords database.

The method according to the invention can be recognized with ageing list entries, and can have timeliness for being based on being somebody's turn to do Property list entries retrieved obtained by resource items carry out ageing sequence, with ageing phase that will likely be with the list entries The resource items sequence of pass shifts to an earlier date, and preferably meets the burst Search Requirement of user.

Fig. 2 is a preferred embodiment of the invention for the method flow diagram that is ranked up to resource items.According to this reality Applying the method for example includes step S1, step S2 and step S3.Wherein, step S3 further comprises ageing sequence step S31.

Step S1 and step S2 are described in detail with reference to the embodiment shown in FIG. 1, and are contained in by reference This, repeats no more.

Then, in step s3, when judging that the list entries has ageing, collator is to based on the input The resource items that sequence is retrieved to obtain carry out ageing sequence, and the resource items after sequence are supplied into the user.This In embodiment, the ageing sequence step S31 in step S3 includes the freshness relevant information according to each resource items, by At least one resource items is wherein selected, and processing is weighted at least one selected resource items, at according to the weighting The step of result after reason is to be ranked up.

Wherein, the freshness relevant information include can be used in determine each resource items foundation or renewal time whether Belong to the relevant information during the timeliness of list entries.Preferably, freshness relevant information includes at least one of following：

1) user's request of the list entries of the foundation of resource items or renewal time and pre-determining is uprushed the time.Wherein, Collator can obtain foundation or the renewal time of each pre-stored resource items, for example, collator or other devices exist While capturing each resource items, foundation or the renewal time of each resource items are stored, for subsequently using；Wherein, the foundation Or renewal time can be foundation or renewal time of each resource items in its network, or collator or other devices grab Take and store or update the time of each resource items.Wherein, before step S31, the user of the list entries of the pre-determining needs The time of uprushing is asked to be determined by collator or other devices according at least one of following factor：A) entered based on list entries Row retrieval changes with time information the resource items quantity that obtains, and the resource items quantity changes with time information in reference The part that Aging Characteristic information is illustrated is described in detail in embodiment illustrated in fig. 1, be will not be repeated here；Collator or its He determines growth intensity of the resource items quantity with the time by changing with time information according to foregoing resource items quantity by device, To determine that user's request is uprushed the time, for example, collator or other devices are by growth intensity of the resource items quantity with the time Once the start time point more than the second predetermined period for increasing threshold value is uprushed the time as user's request；B) list entries And/or the number of times that is retrieved of keyword that includes of list entries changes with time information, the change of the number of times with the time that be retrieved Change information the part that Aging Characteristic information is illustrated is described in detail with reference to the embodiment shown in FIG. 1, no longer go to live in the household of one's in-laws on getting married herein State；Collator or other devices determine to be retrieved by changing with time information according to the foregoing number of times that is retrieved number of times with The growth intensity of time, to determine that user's request is uprushed the time.

Specifically, in each resource items that collator is obtained by being retrieved based on list entries selection set up or more The new time is later than user's request and uprushed the resource items of time, and is weighted processing to selected resource items, with according to should add Result after power processing is ranked up.

For example, the user's request of pre-determining is uprushed, the time is May 12, then collator based on list entries by by being carried out Retrieve the resource items for being later than May 12 come selection setup time in each resource items for obtaining, and according to predetermined weighted value come Processing is weighted to each selected resource items, is ranked up with the result after being handled according to the weighting.

2) resource items included in the history retrieval record of the list entries.

Specifically, to be not included in this defeated for selection in the resource items that collator is obtained by being retrieved based on list entries Enter the resource items in the history retrieval record of sequence, and processing is weighted to selected resource items, at according to the weighting Result after reason is ranked up.Because selected resource items are not included in the history of data sequence retrieval record, Thus, it is believed that the setup time of selected resource items is later than the final updating time of history retrieval record, therefore based on history Retrieval record carrys out the foundation of the resource items of selection or during renewal time should be at the timeliness of list entries.

It should be noted that the above-mentioned examples are merely illustrative of the technical solutions of the present invention, rather than to the limit of the present invention System, it should be appreciated by those skilled in the art that the freshness relevant information of each resource items described in any basis, by wherein select to Few resource items, and processing is weighted at least one selected resource items, with the processing after being handled according to the weighting As a result come the implementation being ranked up, it should be included in the scope of the present invention.

It should be further stated that, collator can first be selected to need the resource items of all weighting processing and is weighted Processing, then again to it is all entered weighting processing and without weighting processing resource items be ranked up；Or, collator The resource items for needing to weight processing are often obtained, i.e., the resource items are weighted with processing, and resource items insertion has been arranged In sequence resource items.

One of preferred scheme as the present embodiment, the method for the present embodiment also includes step S5 and step S6, foregoing Weighting process step in step S31 further comprises according to weighted value, to the selected resource for needing to be weighted processing The step of item is weighted processing.

In the step S5 performed upon step s 2, collator is determined defeated according to the age information obtained in step S1 Enter the user's request change intensity of sequence.

Specifically, collator determines that the mode of the user's request change intensity of list entries includes but is not limited to：

1) when age information includes during collator uprushes keywords database in user's request the Query Result obtained by inquiry, And during user's request change intensity of the Query Result comprising the keyword of uprushing obtained by inquiry, collator is according to Query Result In the user's request change intensity of keyword of uprushing determine the user's request change intensity of list entries.

For example, list entries is " how about it for Fukushima earthquake ", in step sl, in the Query Result that collator is obtained It it is 3 grades comprising the corresponding user's request change intensity of keyword of uprushing " Fukushima earthquake ", then collator will directly uprush key The corresponding user's request change intensity of word " Fukushima earthquake " becomes as the user's request of list entries " how about it for Fukushima earthquake " Change intensity.

In another example, list entries is " Fukushima earthquake nuclear power station ", in step sl, in the Query Result that collator is obtained It is 4.76 comprising the corresponding user's request change intensity of keyword of uprushing " Fukushima earthquake ", keyword of uprushing " nuclear power station " is corresponding User's request change intensity is 2.35, then the collator corresponding user's request change intensity sum 7.11 of keyword that will uprush is made For the user's request change intensity of list entries " Fukushima earthquake nuclear power station ".

2) when age information includes Aging Characteristic information, then collator determines to input sequence according to Aging Characteristic information The user's request change intensity of row.

For example, Aging Characteristic information includes the change of the resource items quantity being retrieved to obtain based on list entries with the time Change information, then collator is according to the machine learning mould such as the SVMs of pre-determining, Bayesian model, maximum entropy model Type determines the user's request change intensity of list entries.Wherein, can by a large amount of will have determined that user's request change intensity with And obtained the change with time list entries of information of resource items quantity machine learning model is trained, to be used for Determine the machine learning model of user's request change intensity.

In another example, in step sl, collator is based on the Aging Characteristic packet that list entries " Fukushima earthquake " is obtained Include following two：1) burst character keyword " earthquake " and burst character semantic structure " proper noun+common noun " are included Burst semantic feature information；2) number of times that is retrieved of list entries " Fukushima earthquake " changes with time information, change letter Breath is as shown in table 3 below：

Time point	Be retrieved number of times
		11 points of March 11 day	324
12 points of March 11 day	235
		13 points of March 11 day	375
14 points of March 11 day	2045
		15 points of March 11 day	15247
16 points of March 11 day	16874

For example, predetermined sorting position is front three sorting position, collator is retrieved based on the list entries To obtain multiple resource items, timeliness collator 3 selected in the plurality of resource items setup time be shorter than 24 hours and with input The matching degree of sequence is more than the resource items of predetermined matching degree threshold value, and then, timeliness collator 3 is further by selected resource The resource items of clicking rate front three are selected in, and by the resource items of the clicking rate front three according to clicking rate from high to low suitable Sequence is placed in front three sorting position；Then, timeliness collator 3 is ranked up using prior art to remaining resource items；Connect , other resource items after identified front three resource items and sequence are supplied to user by collator.

2) one is selected in multiple resource items that timeliness collator 3 is obtained by being retrieved based on the list entries Divide resource items, and processing be weighted to selected resource items, be ranked up with the result after being handled according to weighting, And the resource items after sequence are supplied to user.This will be real shown in reference picture 2 by way of being ranked up weighting processing Apply in example and be described in detail, be will not be described here.

One of it is preferred that, timeliness collator 3 is according to the required resource items quantity showed and required exhibition Existing resource items sorting position, determines the resource items corresponding to the resource items sorting position that the needs show.For example, user equipment The list entries for being inquired about is sent to search engine, then the timeliness collator 3 in search engine is set according to the user The standby disposable resource items quantity that can be presented is 10, is selected in the resource items obtained based on the list entries Select, and determine the corresponding resource items of preceding 10 sorting positions to feed back to user equipment, so that user equipment will sort first 10 Resource items be supplied to user；Then, when user equipment to search engine send page turning request, timeliness collator 3 again by Selected in the resource items obtained based on the list entries, and determine 11 to 20 corresponding resource items of sequence to feed back to User equipment, so that the resource items of the sequence 11 to 20 are supplied to user by user equipment.

One of it is preferred that, after the resource items that 3 pairs of timeliness collator is obtained based on list entries are ranked up, The resource items sorting position of user is presented to as needed, and the resource items for carrying out selected section sorting position are supplied to user.For example, User equipment sends the list entries for being inquired about to search engine, then the timeliness collator 3 in search engine is to base After the resource items obtained in list entries are ranked up, the rule that the resource items after 10 sequences are once provided based on acquiescence Then, the resource items of preceding 10 of sorting are supplied to user equipment, so that the resource items of first 10 of sequence are supplied to by user equipment User；Then, the requests of the resource items of page 3 is provided when user equipment search engine is sent, then timeliness collator 3 is according to the The corresponding resource items of page 3 are 21 to 30 resource items, and the sequence resource items of the 21st to 30 are supplied into user equipment, so that To the sort resource items of resource items of the 21st to 30 of user equipment are supplied to user.

One of preferred scheme as the present invention, also includes updating device (not shown) according to the collator of the present invention, Click information acquisition device (not shown), the second judgment means (not shown) and deletion dress that the updating device is included according to it (not shown) is put, to perform behaviour respectively to being contained in the user's request at least one keyword of uprushing in keywords database of uprushing Make.

Click information acquisition device obtains one or more users to based on the currently processed keyword or comprising this of uprushing The list entries of currently processed keyword of uprushing is come the click information of the resource items after the sequence that obtains.Preferably, the click Information includes being uprushed keyword or list entries comprising the currently processed keyword of uprushing based on currently processed and being obtained The click volume and/or clicking rate of each resource items after the sequence obtained.

Specifically, click information acquisition device obtains the click information of other devices offer；Or, click information obtains dress Put by the way that click behavior of the user based on the resource items after foregoing sequence is monitored and counted within a predetermined period of time, to obtain Obtain click information.

Then, the second judgment means according in abovementioned steps S41 gained click information, judge this uprush keyword whether Ageing mistake.

Wherein, the second judgment means judge uprush keyword it is whether ageing cross mode include but is not limited to：

1) the second judgment means are specified to predetermined sorting position according to by timeliness collator 3 or select to be weighted place The clicking rate or click volume of the resource items of reason, and combine other resource items clicking rate or click volume between, come obtain judge evaluate Value；And judge whether evaluation of estimate is more than or less than the first preset judgment threshold value according to this, to judge currently processed key of uprushing The whether ageing mistake of word.

For example, click information acquisition device obtain user to based on keyword of uprushing " May CPI " retrieved obtained by The click volume of 7 resource items is as shown in table 5 below：

Table 5

Wherein, resource items A and E are the resource items for being designated to predetermined sorting position, and resource items D is to be chosen to be weighted The resource items of processing, then the second judgment means are by resource items A, D and E click volume average value and resource items B, C, F and G click The difference 733 of amount average value is as judging evaluation of estimate, and according to judging evaluation of estimate more than the first preset judgment threshold value 500, judgement The ageing non-mistake of currently processed keyword of uprushing.

2) the second judgment means are shorter than the money of the first scheduled time threshold value according to foundation or renewal time in each resource items The click information of source item, and combine and set up in each resource items or renewal time is longer than the resource items of second scheduled time threshold value Click information, to obtain judgement evaluation of estimate；And judge whether evaluation of estimate is more than or less than the second preset judgment threshold value according to this, come Judge the currently processed whether ageing mistake of keyword of uprushing.

For example, the click that foundation or renewal time in each resource items are shorter than the resource items of 3 days by the second judgment means is believed Breath with set up or renewal time be longer than 90 days resource items click information ratio as judging evaluation of estimate, and according to the judgement Whether whether evaluation of estimate is more than or less than the second preset judgment threshold value, ageing come the keyword of uprushing that judges currently processed Cross.

When judging the ageing mistake of the keyword of uprushing, delete device and deleted in keywords database is uprushed in the user's request The keyword of uprushing.

One of preferred scheme as the present embodiment, the first judgment means 2 further comprise sub- judgment means (not shown) And adding set (not shown).

Whether sub- judgment means meet predetermined condition according to the Aging Characteristic information, judge whether the list entries has Effective property.Wherein, whether sub- judgment means meet predetermined condition according to Aging Characteristic information to judge whether list entries has The mode of effective property is with whether the first judgment means 2 meet predetermined condition to judge list entries according to Aging Characteristic information It is no to have ageing mode same or similar, it will not be repeated here.

When judging that the list entries has ageing, adding set is by the list entries and/or the input sequence The keyword addition user's request in row is uprushed in keywords database.Preferably, adding set will also be corresponding with list entries Aging Characteristic information add the user's request and uprush in keywords database；It is highly preferred that adding set will also be special based on timeliness The information that reference ceases to obtain, for example, the number of times that is retrieved of resource items quantity or list entries is added with growth rate of time etc. The user's request is uprushed in keywords database.

It can be recognized with ageing list entries according to the collator of the present invention, and can be for being had based on this Ageing list entries retrieved obtained by resource items carry out ageing sequence, with timeliness that will likely be with the list entries Property related resource items sequence shift to an earlier date, preferably meet the burst Search Requirement of user.

Fig. 4 is a preferred embodiment of the invention for the collator structural representation that is ranked up to resource items. Age information acquisition device 1, the first judgment means 2 and timeliness collator 3 are included according to the method for the present embodiment.Wherein, Timeliness collator 3 further comprises sub- collator 31.

The judgment means 2 of age information acquisition device 1 and first are described in detail with reference to the embodiment shown in FIG. 2, and It is incorporated herein, repeats no more by reference.

When judging that the list entries has ageing, 3 pairs of timeliness collator is examined based on the list entries Rope carries out ageing sequence come the resource items obtained, and the resource items after sequence are supplied into the user.In the present embodiment, when Sub- collator 31 in effect collator 3 performs the operation of the ageing sequence, and specifically, sub- collator 31 is according to institute The freshness relevant information of each resource items is stated, by wherein selecting at least one resource items, and at least one selected money Source item is weighted processing, with according to the weighting handle after result to be ranked up the step of.

1) user's request of the list entries of the foundation of resource items or renewal time and pre-determining is uprushed the time.Wherein, Collator can obtain foundation or the renewal time of each pre-stored resource items, for example, collator or other devices exist While capturing each resource items, foundation or the renewal time of each resource items are stored, for subsequently using；Wherein, the foundation Or renewal time can be foundation or renewal time of each resource items in its network, or collator or other devices grab Take and store or update the time of each resource items.Wherein, before sub- collator 31 performs operation, the input of the pre-determining The user's request time of uprushing of sequence can be determined by collator or other devices according at least one of following factor：A) base The resource items quantity for being retrieved to obtain in list entries changes with time information, and the resource items quantity changes with time The part that Aging Characteristic information is illustrated is described in detail with reference to the embodiment shown in FIG. 3 for information, will not be repeated here； Collator or other devices determine resource items quantity at any time by changing with time information according to foregoing resource items quantity Between growth intensity, to determine that user's request is uprushed the time, for example, collator or other devices by resource items quantity with the time The start time point of the growth intensity period for increasing threshold value predetermined more than second for the first time uprushed the time as user's request； B) number of times that is retrieved for the keyword that list entries and/or list entries are included changes with time information, the number of times that is retrieved The part that Aging Characteristic information is illustrated is described in detail with reference to the embodiment shown in FIG. 3 for the information that changes with time, It will not be repeated here；Collator or other devices determine quilt by changing with time information according to the foregoing number of times that is retrieved Growth intensity of the number of times with the time is retrieved, to determine that user's request is uprushed the time.

Specifically, select to set up in each resource items that sub- collator 31 is obtained by being retrieved based on list entries Or renewal time is later than user's request and uprushed the resource items of time, and processing is weighted to selected resource items, with basis Result after weighting processing is ranked up.

For example, the user's request of pre-determining is uprushed, the time is May 12, then sub- collator 31 is by by based on list entries Setup time is selected to be later than the resource items on May 12 in each resource items for being retrieved to obtain, and according to predetermined weighting Value to each selected resource items is weighted processing, is ranked up with the result after being handled according to the weighting.

2) resource items included in the history retrieval record of the list entries.

Specifically, select to be not included in the resource items that sub- collator 31 is obtained by being retrieved based on list entries Resource items in the history retrieval record of the list entries, and processing is weighted to selected resource items, it should be added with basis Result after power processing is ranked up.Because the history that selected resource items are not included in data sequence retrieves record In, thus, it is believed that the setup time of selected resource items is later than the final updating time of history retrieval record, therefore it is based on going through History retrieval record carrys out the foundation of the resource items of selection or during renewal time should be at the timeliness of list entries.

It should be further stated that, sub- collator 31 can first select to need resource items and the progress of all weighting processing Weighting handle, then again to it is all entered weighting processing and without weighting processing resource items be ranked up；Or, sub- row Sequence device 31 often obtains the resource items for needing to weight processing, i.e., the resource items are weighted with processing, and by the resource items Insertion is in sequencing resources.

One of preferred scheme as the present embodiment, the collator of the present embodiment also includes strength determination unit and added Weights determining device, foregoing sub- collator 31 further comprises that the weighting processing unit for performing weighting processing operation (is schemed not Show), the weighting processing unit needs the resource items for being weighted processing to be weighted processing according to weighted value to selected Step.

The age information that strength determination unit is obtained according to age information acquisition device 1, determining the user of list entries needs Seek change intensity.

Specifically, strength determination unit determines that the mode of the user's request change intensity of list entries includes but is not limited to：

1) when age information includes during collator uprushes keywords database in user's request the Query Result obtained by inquiry, And during user's request change intensity of the Query Result comprising the keyword of uprushing obtained by inquiry, strength determination unit is according to inquiry As a result the user's request change intensity of the keyword of uprushing in determines the user's request change intensity of list entries.

For example, list entries is " how about it for Fukushima earthquake ", wrapped in the Query Result that age information acquisition device 1 is obtained The corresponding user's request change intensity of " Fukushima earthquake " containing keyword of uprushing is 3 grades, then strength determination unit will directly uprush pass The corresponding user's request change intensity of keyword " Fukushima earthquake " as list entries " how about it for Fukushima earthquake " user's request Change intensity.

In another example, list entries is bag in " Fukushima earthquake nuclear power station ", the Query Result that age information acquisition device 1 is obtained The corresponding user's request change intensity of " Fukushima earthquake " containing keyword of uprushing is 4.76, the corresponding use of keyword of uprushing " nuclear power station " Family changes in demand intensity is 2.35, then strength determination unit will uprush the corresponding user's request change intensity sum 7.11 of keyword It is used as the user's request change intensity of list entries " Fukushima earthquake nuclear power station ".

2) when age information includes Aging Characteristic information, then strength determination unit determines defeated according to Aging Characteristic information Enter the user's request change intensity of sequence.

For example, Aging Characteristic information includes the change of the resource items quantity being retrieved to obtain based on list entries with the time Change information, then strength determination unit is according to engineerings such as the SVMs of pre-determining, Bayesian model, maximum entropy models Model is practised to determine the user's request change intensity of list entries.Wherein, can be by having determined that user's request change is strong by a large amount of Degree and the change with time list entries of information of resource items quantity is obtained machine learning model has been trained, to obtain Machine learning model for determining user's request change intensity.

In another example, the Aging Characteristic information that age information acquisition device 1 is based on list entries " Fukushima earthquake " acquisition includes Two below：1) comprising burst character keyword " earthquake " and burst character semantic structure " proper noun+common noun " Happen suddenly semantic feature information；2) number of times that is retrieved of list entries " Fukushima earthquake " changes with time information, the change information It is as shown in table 6 below：

Table 6

Then strength determination unit calculates the number of times difference that is retrieved at two neighboring time point one by one, and obtain maximum difference= 15247-2045=13202, then, strength determination unit obtain the maximum difference relative maximum be retrieved the ratio of number of times= 13202/17896=73.77%, then, strength determination unit determine that 73.77% belongs to preset range 70-80%, and obtain pre- The corresponding user's request change intensities of scope 70-80% are determined for the second level.Also, strength determination unit is according to as the semantic spy of burst When reference breath includes burst character keyword and burst character semantic structure simultaneously, the burst semantic feature information is corresponding etc. Level adjustment mode is raises the pre-defined rule of one-level, it is determined that including burst character keyword " earthquake " and burst character semanteme knot The corresponding level adjustment rule of burst semantic feature information of structure " proper noun+common noun " is up-regulation one-level.Then intensity is true Determine device according to the level adjustment rule determined based on burst semantic feature information to adjust based on the number of times that is retrieved with the time Change information is come the grade obtained, and the user's request change intensity for finally determining list entries " Fukushima earthquake " is the first order.

Then, weighted value determining device determines weighted value according to the user's request change intensity.

Then, timeliness collator 3 is performed in operation, the present embodiment, is contained in the weighting processing in sub- collator 31 The weighted value that device is determined according to weighting determining device, needs the resource items for being weighted processing to be weighted place to selected The step of reason.

Preferably, weighting processing unit also includes son weighting processing unit, and sub- weighting processing unit determines dress according to weighting The weighted value of determination is put, and combines the foundation of each resource items or renewal time in selected resource items, to selected money The step of source item is weighted processing.

For example, the weighted value that weighting determining device is obtained is 2.3, and need to be weighted when setting up of the resource items of processing Between be 13 points of May 24 day, then son weighting processing unit according to the setup time and current time 20 points of time spacing on May 24 Less than predetermined time interval 1 day, weighted value is raised 0.1, with the weighted value 2.4 after being adjusted, and according to adjustment after Weighted value 2.4, to be weighted processing to the resource items.
