The attribute information of each search key user search in different time sections, attribute information here can be that each retrieval is closed
Retrieval number of the keyword in different time sections, it can such as include for the attribute information of search key " theft "：Nearest one
All user search numbers, a nearest month user search number or user search total degree etc., then add to attribute information
Power computing obtains the weighted value of each search key, specifically can need what is weighted according to determination in configured information dependence information
Weight corresponding to property parameters and the property parameters, configured information here can be configured according to user's request, if user's ratio
, then can be to choose nearly one week user search number and a nearly month user search in dependence information compared with concern retrieval content in the recent period
Property parameters of the number as weighting, are then set corresponding to nearly one week user search number and a nearly month user search number
Weight, if user compare concern user totally retrieve content, can be chosen from the attribute information user search total degree with
The nearly year retrieval number of user, then sets user always to retrieve the weight of nearly 1 year retrieval number of number and user, and then will
Weight corresponding to the property parameters and the property parameters is weighted, and obtains the weighted value of each search key,
Finally prompting keyword of the search key of specified quantity as output is chosen according to the order of weighted value from high to low.
The property parameters that will be weighted in present example in the user search number of different time sections as needs, and then really
Weight corresponding to the user search number of different time sections is scheduled on, further by the user search number and the user search
Weight is weighted corresponding to number, obtains the weighted value of each search key.It should be noted that when above-mentioned different
Between in section weighted value corresponding to user search number be to be set according to configured information, under normal circumstances due to the recent inspection of user
The data of rope number can more reflect the retrieval content that user is concerned about, therefore can be by the retrieval in the distance now nearer period
Weighted value setting is of a relatively high corresponding to number, so as to meet that the retrieval of user is experienced, improves the recall precision of user.
Above-mentioned preset rules are according to retrieval number of each search key in different time sections and then to retrieval
Keyword is screened, and equation below can be used to represent,
Wherein, above-mentioned Y (xa,xm,xw) represent search key weighted value, xaRepresent the use of each search key
Retrieve total degree, x in familymRepresent the nearest month user search number of each search key, xwRepresent each search key most
Nearly one week user search number, QaRepresent the weighted value of user search total degree, QmRepresent a nearest month user search number
Weighted value, QwRepresent the weighted value of nearest one week user search number, SaRepresent that the user search of all search keys is always secondary
Number, SmRepresent the nearest month user search number of all search keys, SwRepresent the nearest one week user of all search keys
Retrieve number.
The weighted value of each search key can be calculated according to above-mentioned formula, weighted value reflection user is concerned about in the recent period
Retrieval content, if weighted value is bigger, illustrate that the frequency that user retrieves in the recent period is higher, comparatively the attention rate of user is got over
Height, therefore, prompting keyword of the search key of specified quantity as output is chosen according to the order of weighted value from high to low,
It more can targetedly prompt user.
For prior art after user is in searching system input search key corresponding ESC, searching system can basis
Search key corresponding to the ESC prompting user ESC, but prior art is only that the ESC is corresponding
Search key be set out to be prompted, do not adjust order from concern angle of the user to the search key,
So that the search key of prompting can not embody Consumer's Experience.The embodiment of the present invention chooses retrieval key by using preset rules
