And/or, search in the network data with each intention class label respectively according to described query string Rope, obtains the information record of each intention classification.Will described query string each intention classification correspondence in the whole network Search engine in scan for, obtain each search engine return the search with each intention class label As a result, thus form the information record of each intention classification.Owing to the classification of search engine each in the whole network is objective Existing, such as mp3.baidu.com is the search engine of music categories, and news.sogou.com is news The search engine of classification, video.baidu.com is that video class is other searches element engine etc., can search from these Index directly obtains correspondence in holding up and is intended to the information record of classification, so the intention classification of the application is network The attribute of the objective reality corresponding to data.

In the embodiment of the present application, described intention classification is mainly used in distinguishing different letters in each information record Breath demand, in a preferred embodiment of the present application, its specifically can include video, picture, information, Resource, comment or rate of exchange classification etc..In reality, those skilled in the art can also according to actual needs, What information record was divided into other is respectively intended to classification, and with the different information requirement of difference, the application is to specifically The sorting technique of information record be not any limitation as.

Step 103, according to distribution being intended to classification each under environmental information corresponding to described query string, to meaning Figure classification is ranked up, and according to the order of the ranking results adjustment information record being intended to classification；Wherein, Under the environmental information that described query string is corresponding, each distribution being intended to classification is had environmental information by according to record User journal is analyzed statistics and obtains.

In practice, can select to use browser log or search engine according to practical application request The user journals such as inquiry log carry out statistical analysis, and such as, search engine typically can arrange inquiry log, And browser client typically can arrange browser log, the application is at existing inquiry log or browser Environmental information is added on the basis of daily record.

In a preferred embodiment of the present application, described user journal includes browser log and/or looks into Ask daily record.Described browser log record has user totem information, browses web-page histories and corresponding environment Information；Described inquiry log record have user totem information, query string and corresponding web page operation history and Environmental information, described web page operation history is the net being user-operably in the information record that query string is corresponding Page record.

P(I_c| T) can be used for representing intention classification I under environmental information T that described query string is corresponding_cDistribution, According to theory of probability and mathematical statistics method, can use following formula that it is derived:

$\begin{array}{c}P\left(I_c|T\right)=\underset{d}{\mathrm{\Σ}}p\left(I_{c}d|T\right)\\ =\underset{d}{\mathrm{\Σ}}\frac{p\left(I_{c}dT\right)}{p\left(T\right)}=\underset{d}{\mathrm{\Σ}}\frac{p\left(I_c|dT\right)p\left(dT\right)}{p\left(T\right)}=\underset{d}{\mathrm{\Σ}}\frac{p\left(I_c\right|dT)p\left(d\right|T)p\left(T\right)}{p\left(T\right)}=\underset{d}{\Σ}p\left(d\right|T)p\left(I_c\right|dT)\end{array}---\left(1\right)$

Wherein,For to joint probability distribution P (I_c| T) carry out the operation of marginalisation.

In a preferred embodiment of the present application, can there is environmental information according to record as follows User journal be analyzed statistics, obtain under the environmental information that described query string is corresponding be intended to classification point Cloth:

Sub-step A1, under the environmental information that described query string is corresponding according to user journal in the whole network Webpage is analyzed statistics, obtains webpage distribution p under the environmental information that described query string is corresponding (d | T)；

When using user journal to add up, can perform under the environmental information that described query string is corresponding The operation of statistics p (d), wherein, the operation using inquiry log to be analyzed adding up p (d) can use Following formula represents:

$p\left(d\right)=\underset{x}{\Σ}p\left(d\right|x)p\left(x\right)---\left(2\right)$

Wherein, x record in inquiry log.

The operation example that use browser log is analyzed adding up p (d) is as follows: add up certain webpage d The number of times occurred in browser log, in some cases, can be with certain webpage d in browser log The number of times of middle appearance divided by all webpages in browser log occur number of times.

Sub-step A2, under the environmental information that described query string is corresponding for certain particular webpage according to user Daily record is analyzed statistics to each intention classification, obtains ad hoc networks under the environmental information that described query string is corresponding The intention categorical distribution p (I of page_c|dT)；

In implementing, can first add up p (I_c):

1, as a example by browser log, such as represent five now with five pillars and be intended to classification I_c, as Really a webpage belongs in some (multiple) intention classification, just increases by 1 on corresponding pillar；From And obtain the numerical value on each pillar, namely each intention classification I_cProbability distribution；

2, inquiry log is used to be analyzed adding up p (I_c) operation can be represented by the formula:

$p\left(I_c\right)=\underset{x}{\Σ}p\left(I_c\right|x)p\left(x\right)---\left(3\right)$

P (I is added up for certain particular webpage under environmental information T that described query string is corresponding_c), then must Arrive p (I_c|dT)。

Sub-step A3, with webpage as statistical sample, net environmental information under corresponding to described query string Under the environmental information that page distribution is corresponding with described query string, the product of the intention categorical distribution of particular webpage enters Row summation, obtains under the environmental information that described query string is corresponding each distribution being intended to classification:

In the case of query string is identical, prior art can represent consistent information record to the whole network user, Without considering the individual demand of user.

For the problems referred to above, in a preferred embodiment of the present application, considering current context information On the basis of, it is also possible to according to active user for the interest corresponding letter to each intention classification being intended to classification Breath record is ranked up；Correspondingly, described method can also include:

Identify the user totem information of the active user that described query string is corresponding；

According to active user's each distribution being intended to classification under the environmental information that described query string is corresponding, to meaning Figure classification is ranked up, and adjusts the order of each information record according to the ranking results being intended to classification, wherein, Active user's each distribution being intended to classification under the environmental information that described query string is corresponding has ring according to record The user journal of environment information and user totem information is analyzed statistics and obtains.

Excluding the factor of environmental information, different user is intended to classification to difference different interest, such as, User A grows tender of variety show, and every day all can watch the form of video with search engine and/or browser Obtain the variety show wanted, and user B grows tender of star's picture, habitually to search for and/or clear The form of video of looking at obtains the star's picture wanted.

This preferred embodiment method of theory of probability and mathematical statistics studies user for being intended to classification The regularity of interest, here, each distribution being intended to classification under the environmental information that comprehensive described query string is corresponding Regularity, finally, this preferred embodiment statistics is user in environmental information corresponding to described query string Under the distribution of each intention classification.

There is different interest owing to different user is intended to classification to difference, and have environmental information according to record Being analyzed statistics with the user journal of user totem information, the active user obtained is at described query string pair Under the environmental information answered, each distribution being intended to classification is ranked up, it is possible to by institute interested for active user Before stating intention classification coming, therefore, the application enables to information record and is closer to reflect user The personalized real information demand of interest-degree.

P(I_c| T, u) can be used for representing that active user is respectively intended under the environmental information that described query string is corresponding The distribution of classification, its available following formula is weight averaged statistics and obtains:

P(I_c|T,u)∝λP(T|I_c)P(I_c)+(1-λ)P(T|I_c,u)P(I_c|u) (4)

Wherein, u represents ID (userid), owing to all can record user's mark in every user journal Know, so, just can obtain all access records of each u, and then, the access record for u is added up P (Ic) i.e. can get P (I_c| u), P (I_c| u) can reflect that refer to user u is respectively intended to categorical distribution；λ For random factor.

For specific intended classification I_cPerform p (T) statistical operation i.e. can get p (T | I_c), p (T) Can calculate by equation below:

$p\left(T\right)=\underset{d}{\Σ}p\left(dT\right)---\left(5\right)$

Wherein, p (dT)=p (T | d) p (d) (6)

Wherein, the sum that the numerical value that the available webpage d of p (T | d) falls under environmental information occurs with webpage d Ratio calculation obtains；For specific user u and specific intended classification I_cPerform the statistical operation of p (T) I.e. can get P (T | I_c,u)；Random factor λ is for representing that all users are at environment corresponding to described query string The distribution being intended to classification under information is intended to class with active user under the environmental information that described query string is corresponding Other distribution, can determine the numerical value of λ according to the actual requirements.

For example, it is possible to by manually marking the log information of user in T, marked content is for being intended to Classification, adjusts λ so as to get best is intended to describe λ value corresponding during accuracy rate, and wherein, T is permissible It it is the same T time section in many days user journals.

Specifically, manually it is labelled with the model answer being intended to classification ranking results, adjusts λ=0.1,0.2 ..., 0.9}, utilize the result that formula (4) the right is calculated under different λ, contrast standard Answer and the intention classification ranking results of formula clearing, can count formula under specific λ calculated Accuracy rate, λ value corresponding when accuracy rate is the highest is exactly the λ value finally determined.Wherein it is possible to utilize NDCG (normalization accumulation discount taken, Normalized Discounted Cumulative Gain), NDCG is a kind of to search engine or the tolerance of relative program effectiveness, its calculate before the phase of k bar result The computing formula of closing property score is:

$NDCG\left(k\right)=G_{\max ,i}^{-1}\left(k\right){\mathrm{\Σ}}_{j:{\mathrm{\π}}_i\left(j\right)\≤k}\frac{2^{y_{i,j}}-1}{{\log }_2(1+{\mathrm{\π}}_i(j\left)\right)}$

I is expressed as i & lt search；J is expressed as j-th strip result；y_i,jIt is expressed as the relevant of j-th strip result Property mark score, 5 grades of systems；π_iJ () is expressed as this result position in the ranking.

And for example, it is also possible to the directly numerical value of setting λ, 0.6,0.8 etc., the application concrete number to λ Value is not any limitation as.
