Step 205, the first paraphrase of idle data item is shown to user by display interface.
After the paraphrase update that would sit idle for data item, in order to which user is made to confirm the more new state of idle data item, it can would sit idle for
The first paraphrase after data item update, is shown on display interface, with the update status of the idle data item of display directly perceived.
Illustrate above-described embodiment in order to clearer, for step 202, an embodiment of the present invention provides two kinds according to each
The use information of data item, the method that idle data item is identified from data item.Fig. 3 is one kind provided in an embodiment of the present invention
According to the use information of each data item, the method flow schematic diagram of idle data item is identified from data item.
As shown in figure 3, this method includes：
Step 301, according to the use information of the candidate data item of previous period, the first data in present period are obtained
.
Wherein, the previous period is the period formed from default first moment to current time, and present period is default
Period for being formed at the second moment to current time, wherein, at the time of the second moment was after the first moment.It is as it can be seen that previous
Period includes present period.
In the present embodiment, using all data item reached the standard grade within the previous period as candidate data item.Need what is illustrated
It is, it, can be using data item all in the previous period as candidate data if the previous period is first initial period
.
As a kind of possible realization method, according to the frequency of use of each candidate data item in the previous period, obtain
The first data item in present period.
Specifically, according to the use information of each candidate data item in the previous period, such as usage time counts previous
The access times of each candidate data item in period.Then, the access times of each candidate data item are added, and will add up
The number of obtain afterwards and value divided by candidate data item obtains the average use time of all candidate data items of previous period
Number.Afterwards, the average access times of the access times of each candidate data item and all candidate data items are made into ratio, obtained every
First frequency of use of a data item.
Further by the first frequency of use of each candidate data item compared with default threshold value, if first uses frequency
Rate illustrates that within the previous period candidate data item frequency of use than relatively low, is more likely to leave unused without departing from default threshold value
Data item, therefore be the first data in present period without departing from the candidate data item of default threshold value by the first frequency of use
.
Step 302, according to the generated time of the first data item in present period, to all first numbers in present period
It is screened according to item, obtains the candidate data item in present period.
Since the generated time of data item is closer to current time, that is, data item reach the standard grade it is more late, then when previous
The frequency of use of data item is lower in section.Therefore, according to the frequency of use of the candidate data item in the previous period, what is filtered out works as
In the first data item of preceding period, there may be the data item reached the standard grade soon.
In order to improve the recognition accuracy to data item of leaving unused, in the present embodiment, according to the first data in present period
The generated time of item, all first data item in present period are screened, obtain the candidate data item in present period.
As a kind of possible realization method, the first number that frequency of use is high in present period can be screened out according to frequency of use
According to item.Specifically, according to the usage time for the first data item for burying point probe record, each first data item is counted when current
Access times in section, and the average access times of all first data item are calculated, further made according to the first data item
With number and the average access times of all first data item, second use frequency of first data item in present period is calculated
Rate.
Afterwards, by the second frequency of use of the first data item compared with default threshold value, if the second frequency of use
Without departing from default threshold value, illustrate that the second data item frequency of use is relatively low, then using the first data item as the time in present period
Select data item.All second frequency of use are selected in the first data item as a result, without departing from the first data item of default threshold value
As the second data item in present period.
In order to screen out the first later data item of reaching the standard grade, a moment is chosen after the second moment as the 3rd moment, from
3rd moment value is to the period that current time is formed as the 3rd period, and to screen out, generated time is later but frequency of use is higher
Data item.
Specifically, according to the generated time of the first data item, in the first data item out of present period, generation is selected
Time is in the first data item of the second period as the 3rd data item.Then, count each 3rd data item at second
Access times in section, and calculate the average access times of all 3rd data item.Afterwards, each 3rd data item is made
With the average access times of number and all 3rd data item, the 3rd frequency of use of the 3rd data item is calculated.Further will
3rd frequency of use selects threeth data of the 3rd frequency of use without departing from default threshold value compared with default threshold value
Item is as the 4th data item in present period.
Finally, the 4th data item in the second data item in present period and present period is subjected to duplicate removal processing, i.e.,
By the second data item in current slot compared with the 4th data item in current slot, if there is identical
Two data item then delete a data item for avoiding the occurrence of repetition, after duplicate removal is handled, it is possible to obtain the time of present period
Select data item.
In the present embodiment, according to the generated time of the first data item, later data item of reaching the standard grade is screened out, it is not busy to improve identification
Put the accuracy rate of data item.
Step 303, if present period is objective time interval, using the candidate data item in present period as idle data
.
The goal period can be configured as needed, such as either one month or half three months.
It is understood that if present period is not objective time interval, using the candidate data item of present period as before
The candidate data item of one period, and the use information for re-executing the candidate data item according to the previous period is returned, it obtains
The first data item and subsequent step in present period, until present period is objective time interval.
By taking the data item of certain product as an example, all data item in nearest 3 years are chosen, frequency is used according to each data item
Rate and default threshold value choose first data item of nearest 2 years.
Then, according to the generated time of the first data item, all first data item in nearest 2 years is screened, are had
Body step can be found in above-described embodiment, obtain the candidate data item of nearest 2 years.
Further, according to the candidate data item of nearest 2 years, first data item of nearest 1 year is obtained, according to the above method,
Obtain the candidate data item of nearest 1 year.
Further according to the candidate data item of nearest 1 year, the first data item of nearest half a year is obtained, according to the above method, is obtained
The candidate data item of nearest half a year.
It repeats the above steps, gets the candidate data item of nearest 1 month, since nearest 1 month is objective time interval, then will
The candidate data item of nearest 1 month is as idle data item.
Above-mentioned frequency of use and generated time for according to data item, the method for identifying idle data item, as one kind
The usage time interval according to data item is described below in realization method optionally, the method for obtaining idle data item.
Specifically, according to bury point probe record data item use information, such as usage time, count from the first moment to
The access times of each data item in the present period at current time obtain the average access times of all data item.Then, root
According to the average access times of all data item and the access times of each data item, each data item is calculated in present period
Frequency of use.
Afterwards, the size of the frequency of use of more each data item and default threshold value, by frequency of use without departing from default
Threshold value data item as candidate data item.
In order to improve the accuracy rate of the idle data item of identification, extracted from candidate data item using the longer candidate in interval
Data item is as idle data item.Specifically, use when last time of the candidate data item in present period uses is obtained
Time calculates usage time when last time uses to the time interval at current time, will be between time interval and preset time
Every being compared.If time interval is more than prefixed time interval, illustrate that candidate data item is not used by for a long time, it can be by candidate
Data item is as idle data item.Thus, it is possible to all idle data item are selected from candidate data item.
Above-mentioned is two kinds of use informations according to each data item provided in an embodiment of the present invention, identifies idle data item
Method.
