Related term, it will be understood that the embodiment of the present invention is not any limitation as the particularly relevant word of news primary keyword.
Additionally, it is appreciated that vocabulary is same or similar or related to news primary keyword in the current input content
The alternative embodiment that the current input content matches with news primary keyword is intended only as, in fact, those skilled in the art
Can also be according to practical application request, other situations for being matched using the current input content and news primary keyword, for example,
The analysis result of the current input content and news primary keyword match etc..
It is related between current input content and news in order to accurately constrain in a kind of alternative embodiment of the present invention
Property, above-mentioned current input content meets preset news correlated condition, can include：The current input content and the main key of news
Word matches, and the current input content meets preset news statement pattern.Wherein, which can use
In constraining, news is corresponding to talk about sentence.Wherein, which can be according to multiple users or active user
History input behavior data obtain.In a kind of application example of the present invention, it is assumed that the embodiment of the present invention is from a large number of users
It user is excavated in history input behavior data talks about the pattern of news and be：" news for listening XXX ", " you know XXX ",
And assume that the embodiment of the present invention has excavated news primary keyword " Ah method dog " from the history input behavior data of multiple users,
In this way, once " you listened the news of Ah method dog for active user or the input of its peer user", then in corresponding current input
Hold not only comprising news keyword " Ah method dog ", but also meet preset news statement pattern " news for listening XXX ", therefore think this
Current input content meets preset news statement pattern.It is appreciated that those skilled in the art can be according to practical application need
It asks using required preset news statement pattern, the embodiment of the present invention is not subject to for specific preset news statement pattern
Limitation.
In the embodiment of the present invention, it is new that one or more can be excavated from the history input behavior data of multiple users
Hear primary keyword；Wherein, the plurality of user can be all or part of user in the whole network user, and input method APP can lead to
Cross the history input behavior data that client collects each user.Also, for the timeliness for ensureing news primary keyword, the history
Input behavior data can be the data of a preset time period, the initial time of the preset time period and the difference of current time
Can be less than time threshold, for example, the time threshold can be 2 it is small when, 12 it is small when, 24 it is small when, 48 it is small when or 72 it is small when
Deng it is possible thereby to ensure the timeliness of news primary keyword.Certainly, for the ease of analysis, more than the time threshold starting when
Between (for example, the history input behavior data before 100 days) also in protection scope of the present invention, the embodiment of the present invention is defeated for history
Enter the corresponding preset time period of behavioral data not to be any limitation as.
In a kind of alternative embodiment of the present invention, news primary keyword can be excavated as follows：To multiple use
The vocabulary attribute of each vocabulary is analyzed in the history input behavior data at family；Word is chosen from the history input behavior data
The attribute that converges meets the vocabulary of preset attribute condition, as news primary keyword.Optionally, above-mentioned vocabulary attribute includes：Word frequency and
At least one of number of users.Wherein, word frequency namely the occurrence number of certain vocabulary, optionally, the word frequency can be total word frequency,
Or the word frequency in chronomere (such as one day)；Number of users namely certain vocabulary were inputted by how many user, similarly, the use
Amount amount can be total number of users, or the number of users in chronomere (such as one day).
In another alternative embodiment of the present invention, above-mentioned preset attribute condition can specifically include：
Increment rate of the word frequency in the first preset time period is more than first threshold；And/or
Increment rate of the number of users in the second preset time period is more than second threshold.
Wherein, increment rate of the word frequency in the first preset time period is more than that first threshold can correspond to the feelings that word frequency explodes
Shape.For example, certain vocabulary was at past 100 days, daily input quantity only has 50000 or so, and the input quantity of today explodes suddenly, becomes
100000, then it is related with this word namely may have occurred relevant new with the vocabulary to illustrate centainly to have occurred any thing
It hears.
Increment rate of the word frequency in the first preset time period is more than that first threshold can correspond to the situation that word frequency is stepped up.
For example, the word frequency of some vocabulary is incremented by by day in the first preset time period, day before yesterday 4w increased to 5w yesterdays, and became 6w etc. today,
It is considered that the vocabulary may be related to news.
Increment rate of the number of users in the second preset time period is more than that second threshold can correspond to the use for inputting certain vocabulary
The situation that amount amount explodes.For example, the original daily number of users of certain vocabulary is 5000, now daily number of users becomes suddenly
For 10000, then it is also assumed that the vocabulary may be related to news.
Increment rate of the above-mentioned word frequency in the first preset time period can be expressed as：Two days adjacent (one day after with the previous day)
Word frequency difference and the word frequency of the previous day ratio, increment rate of the above-mentioned number of users in the second preset time period can represent
For：The number of users difference of two days adjacent (one day after with the previous day) and the ratio of the number of users of the previous day, it will be understood that this
Field technology personnel can be according to practical application request, using rational first threshold and second threshold, the embodiment of the present invention pair
It is without restriction in specific first threshold and second threshold.
Additionally, it is appreciated that above-mentioned preset attribute condition is intended only as the alternative embodiment of the present invention, in fact, ability
Field technique personnel can also be according to practical application request, using other preset attribute conditions, as word frequency or number of users are more than
Corresponding threshold value etc., the embodiment of the present invention are not any limitation as specific preset attribute condition.
In practical applications, noise may be included in the numerous news primary keywords excavated, that is, some vocabulary can
It can be erroneously identified as news primary keyword, but actually itself and one news of non-corresponding.For above-mentioned noise problem, in this hair
In a kind of bright alternative embodiment, can also noise filtering be carried out to the news primary keyword by pseudo-linear filter mode.
Wherein, above-mentioned pseudo-linear filter mode can carry out news search using the news primary keyword as search term, and according to phase
The first news search result answered verifies whether the news primary keyword is noise.
The present invention another alternative embodiment in, it is described by pseudo-linear filter mode to the news primary keyword
The step of carrying out noise filtering, can specifically include：It searches for obtain corresponding first news according to the news primary keyword and search
Hitch fruit；The corresponding associative key of the news primary keyword is excavated from first news search result；According to described in
Associative key is searched for obtain corresponding second news search result；It is searched according to the news primary keyword in second news
Appearance information in hitch fruit judges whether the news primary keyword is noise, if so, filtering out the main key of the news
Word.It is alternatively possible to N number of first news search result for coming front is chosen, in the news of N number of first news search result
Appearance is segmented, and counts the word frequency of each vocabulary, therefrom chooses the highest M vocabulary of word frequency, as associative key, then will
The M associative key is scanned for as search term, to obtain corresponding second news search result, wherein, M, N are certainly
So number.Appearance information of the news primary keyword in the second news search result can include：Occurrence number, reverse document-frequency
Deng can then occur information according to this and judge whether the news primary keyword is noise.Corresponding judgment mode can there are many,
If for example, ratio of news primary keyword occurrence number and the number of the second news search result in the second news search result
More than the 3rd threshold value, it may be considered that the news primary keyword is not noise, therefore it can be retained, otherwise, can be somebody's turn to do
News primary keyword is noise.
It is appreciated that above-mentioned pseudo-linear filter mode of crossing is to the mode of news primary keyword progress noise filtering
As alternative embodiment, in fact, the mode of other noise filterings may be employed in those skilled in the art, for example, manual examination and verification
Mode or user's ballot mode etc., the embodiment of the present invention to the news primary keyword for carrying out noise filtering
Concrete mode be not any limitation as.
It should be noted that those skilled in the art can be determined according to time application demand first threshold, second threshold,
The concrete numerical value of 3rd threshold value, for example, first threshold, second threshold, the tool of the 3rd threshold value can be determined by way of experiment
Body numerical value, the embodiment of the present invention is for the concrete numerical value and its method of determination of the threshold values such as first threshold, second threshold, the 3rd threshold value
It is not any limitation as.
In the embodiment of the present invention, optionally, the step of the above-mentioned acquisition news primary keyword corresponding targeted news,
