A kind of method that content source is carried out classification of the embodiment of the invention as shown in Figure 4, concrete steps are as follows:

S401: search server received content Login.

Search server receives the login request message of various content source, this login request message content log-on message.Content registration information can comprise whether essential information, content source type, details, searching interface information, search result information, content pass through the one or more of manual sorting etc.Wherein searching interface information is necessary, and other are option.Essential information comprises the title of content source, affiliated tissue, description, associated person information; The description of content source is the simple description to content source.The associated person information of content source can be information such as name of contact person, telephone number, E-mail address; Details comprise the ground domain information of content source and the search performance information of content source, and wherein domain information can be served the region that can cover for this content source; Region such as the search content source, a restaurant in Shenzhen is China/Guangdong/Shenzhen.Searching interface information can be the searching interface that Gong the search server of content source calls, and comprises inquiry URL, query argument, supporting language, inputting character code etc.Search result information can be the form of Search Results, as the RSS/ATOM form.The content source pay imformation can comprise charge method and pricing information, and charge method is divided into pre-payment, pay-per-click or free again; Pricing information is the price of every content.

S402: search server carries out classification to the content source that receives.

Behind the log-on message in search server received content source, according to log-on message and manual intervention or preset rule content source is set a rank, as carrying out classification to content according to whether paying, perhaps whether content source has cooperation agreement that content is carried out classification with search server, and perhaps whether content source carries out classification or the like through artificial treatment to content.

For example search server can be four ranks that are redefined for of content source: one-level content source, secondary content source, three grades of content source, level Four content source.As following table 1:

Classification logotype	The content source rank	Describe
			??1	The one-level content source	The content source that search server is trusted fully
??2	The secondary content source	With search server the content source of cooperation agreement is arranged
			??3	Three grades of content source	Content source through the search server authentication
??4	The level Four content source	Common content source

Table 1

For the content source of search server to user's charge, or the free content source of mobile operator, as the content source that search servers such as CRBT, mobile phone newspaper content source are trusted fully, search server can divide it into the one-level content source; For being ready the data of content source are shared fully to search server, perhaps be signed with the cooperation agreement content source with search server, search server can divide it into the secondary content source; For the content source of content through manual sorting, after the search server authentication, search server can be set at three grades of content source to it; For common content source, search server can be set at the level Four content source to its rank, and search server is stored in the content source classification results in the content source information storehouse.For the higher content source of rank, under equal conditions, the priority scheduling of search server will be obtained.

Be an example of setting the registration content source level below, suppose the log-on message such as the following table 2 of content source:

Table 2

After search server receives above-mentioned log-on message, according to table 2 as can be known: this content source is a location finding engine, and its charge method is free, and the content of content source is through manual sorting.According to above-mentioned explanation to the content source classification, search server can be set at three grades of content source to it.

A kind of method that the user is carried out classification of the embodiment of the invention as shown in Figure 5, concrete steps are as follows:

S501: search server receives registration request from user message, and described login request message comprises user's registration information; User's registration information can comprise information such as user ID and optional information.Optional information can be the user profile of obtaining from the third party, for example can be for comprising the information such as mobile operator under the user mobile phone number, and user ID can be user's phone number.

S502: according to user's registration information, search server sends user ID to third-party server, and wherein the third party can be the mobile operator under the user.

S503: search server receives the user profile that third-party server returns.

Third-party server is according to the user ID that is received, and user profile is obtained in inquiry, and returns to search server.Wherein user profile can comprise every user's average income (Average Revenue Per User, ARPU) value, cell-phone number type, in the net time, to information such as the paying of search service, user integral, ARPU be in the time period operator from the resulting profit of each user.The cell-phone number type is the type of service of the mobile operator under the cell-phone numbers such as Global Link, walk in the Divine Land, M-ZONE, TD pioneer's card.To the paying information of search service be the user whether to the search service defrayment, search server can be carried out free to user search, also can carry out charge to user search.Mobile operator then can charge to the user for search server, can subscribe to search service and defrayment at the mobile operator place such as the user; For the paying customer, can obtain the search server better service, have only the paying customer just can search such as some information.Integration when user integral can represent that the user searches for also can be represented integration of user account or the like.

S504: search server is set a rank according to user's registration information with from the user's information that the third party obtains.

In embodiments of the present invention, search server can be set at three ranks to the user: one-level user, secondary user, three grades of users, and as shown in table 3.

Classification logotype	Class of subscriber	Describe
			??11	One-level user	VIP user
??12	Secondary user	Advanced level user
			??13	Three grades of users	Domestic consumer

Table 3

Search server carries out classification according to user's registration information and the user profile that obtains from the third party to the user.The rule of classification can be varied, can set rank to the user according to manual intervention or preset rule.For example if the user pays to search service, then search server is set at the one-level user to this type of VIP user; Belong to the special mobile phone type if user's ARPU value reaches a predefined numerical value or reaches certain numerical value or user mobile phone number in the net time, such as Global Link, then search server is drawn this type of advanced level user and is set secondary user; For not satisfying above-mentioned condition, to incorporate into be three grades of users.Search server is stored in user's classification results in the user information database.

For the high more user of rank, the search service of high-quality more will be obtained.Such as some content source, have only to certain other user of level and just can use.

What other user of level can use what rank content source for, search server can be provided with multiple strategy.For example, for three grades of users, default setting can use three grades of content source and level Four content source; For secondary user, default setting can use secondary, three grades and level Four content source; One-level user's default setting can use the content source of all rank.

The method of a kind of search of the embodiment of the invention as shown in Figure 6, search server is selected the operable content source of this searching request according to user class, and searches in the content source of selecting.Concrete steps are as follows:

S601: search server receives the searching request that the user submits to.

Can carry search condition and additional information in the searching request that the user submits to.Search condition can be the search key or the search expression formula of user's input.Additional information can be for additional search restrictive condition, as parameters such as " secondary user's experience ", " one-level user experiences ".The searching request that the user submits to can be passed through third-party network, for example passes through the network of mobile operator, and the third party submits to search server in the lump to user ID and searching request.

S602: after search server receives searching request, obtain user's rank, select the spendable content source of searching request;

At first, search server extracts user ID and additional information from searching request, and obtains out user's rank according to user ID and additional information.

If do not contain additional information in the searching request, search server is then selected user's rank according to user ID.If do not get access to user ID, search server then obtains user's rank according to additional information, and for example: additional information is " secondary user's experience ", and then user's rank is a secondary, and for this search, the described rank of obtaining is exactly user's a rank.If when containing additional information and user ID in the searching request, then obtain user's rank according to the combination of user ID and additional information.Obtain the user class of user ID correspondence and the user class of additional information correspondence, select the higher level of above-mentioned two user classs else to be user class.For example: additional information is " secondary user's experience ", and the user class of user ID correspondence is three grades, and then for this search, user's rank is a secondary.When additional information was " secondary user's experience ", the user class of user ID correspondence was an one-level, and then for this search, user's rank is an one-level.

Secondly, obtain the scope of the spendable content source of user according to user class.

If by classification, then search server selects the user can use the level range of content source according to user's rank to content source in search server.For example, if user's rank is three grades, then the content source scope that can use of user is level Four and three grades of content source.

If user's rank is a secondary, then the content source scope that can use of user is level Four, three grades and secondary content source.

If user's rank is an one-level, then the content source scope that can use of user is the content source of all rank.

For example search server extracts user ID from searching request, and does not have additional information in the searching request, and obtaining the user according to user ID is three grades of users.Then described user can use level Four and three grades of content source.And therefrom select best content source.

Table 4 is an example form of content source rank management.

The level Four content	Three grades of contents	The secondary content	The one-level content
				Content source 41	Content source 31	Content source 21	Content source 11
Content source 42	Content source 32	Content source 22	Content source 12

The level Four content	Three grades of contents	The secondary content	The one-level content
				??.....	??.....	??......	??......

Table 4

As shown in table 4, the operable content source of this user is content source 41, content source 42, content source 31, content source 32, and wherein 41,42,31,32 etc. is the content source identification information.

Search server is selected more excellent content source according to the search condition of user class and searching request for this user search this time, for example the user is three grades of users, the search condition of searching request is song A, and then search server is selected three grades of content source relevant with song A with level Four for this user search this time.The method in concrete chosen content source has multiple.Search server can select wherein a kind of method to select more excellent spendable content source.The embodiment of the invention is enumerated four kinds of methods.Be respectively:

Method 1: utilize first index to select to use the method for content source;

After the various content source that search server is integrated, can set up first index for these content source.The method for building up of unit's index has multiple, but does not have unified algorithm and method.During concrete enforcement, no argument index with what algorithm makes up, and all is in order to calculate the Qu Peidu of searching request and content source finally.Described district degree of joining is meant the similarity of the Query Result of search engine for given inquiry (also being search condition), and its similarity size can be similar to the relevant useful degree size with search engine of the described given inquiry of reflection.In general, for given inquiry, Qu Peidu is high more, and then the Query Result of search engine is correct more.Being one below utilizes first index to carry out the example of the selection of content source.

Table 5

Wherein, content source delegation represent content source.Term one row representative search search condition.Overall situation inverse file frequency weight gidf is the total number of files and the ratio that contains the number of files of search condition q in the content source; Suppose that di is the similarity weights of term keyi in the file d of content source D, the normalization weights of keyi in file d are di/|d| so; Wherein, | d| is the mould of the similarity weights of term keyi in All Files, | d|=sqrt (d1*d1+d2*d2+...+dn*dn); Maximum and mean value in the All Files that maximum normalization weights and average normalization weights are respectively content source D in the normalization weights of key_i.For given search condition q=(q1, q2 ..., qk) be query vector, then the Qu Peidu of q in content source

$R=\underset{1\≤i\≤k}{\max }\frac{\{q_i*{\mathrm{gidf}}_i*{\mathrm{mnw}}_i+\underset{j=1,j\≠i}{\overset{k}{\mathrm{\Σ}}}{q}_j*{\mathrm{gidf}}_j*{\mathrm{anw}}_j\}}{\left|q\right|}---\left(5.1\right)$

Search server is according to the search condition in the searching request.Suppose that search search condition keyword cuts behind the speech to { Key1, Key2} get query vector q={1 in this example, 1} looks like for after keyword cut speech, and two speech weights are the same.According to data in the table 5 and formula 5.1, the Qu Peidu of search condition in content source 41, content source 42, content source 31, content source 32 is respectively:

R41=0.2828; R42=2.8991; R31=0.2263; R32=3.0052; Obviously, the Qu Peidu of content source 42, content source 32 is much larger than the Qu Peidu of content source 41, content source 31, and then chosen content source 42 and content source 32 are as spendable content source.

Method 2: utilize first index and content source rank to select to use the method for content source

For by the content source of classification, in order to make high level content source can preferentially obtain scheduling, for each other content source of level, can on degree of joining basis, the district of first index, add a harmonic coefficient, the concrete value of this harmonic coefficient is value rule of thumb, is the example of a harmonic coefficient below.

The content source rank	The level Four content source	Three grades of content source	The secondary content source	The one-level content source
					Harmonic coefficient	??0.2	??0.3	??0.4	??0.5

Quote the result of the Qu Peidu that adopts first index calculation content source, after the influence of consideration content source rank, the Qu Peidu of described search search condition in content source 41, content source 42, content source 31, content source 32 is respectively:

R41＝0.2828+0.2＝0.4828；R42＝2.899+0.2＝3.099；R31＝0.2263+0.3＝0.5263；R32＝3.0052+0.3＝3.3052；

Obviously, the Qu Peidu of content source 42, content source 32 is much larger than the Qu Peidu of content source 41, content source 31, and then chosen content source 42 and content source 32 are spendable content source.

Method three: the present invention is another kind of to select spendable content source method can also utilize first index and user satisfaction feedback information to plant in conjunction with selecting, and will introduce in another embodiment of the present invention.

Method four: the present invention is another kind of to select spendable content source method can also utilize first index, content source rank and three kinds of combinations of user satisfaction feedback information to select, and will introduce in another embodiment of the present invention.

S603: search server according to select content source search for.

Search server sends described searching request search condition to the content source of selecting for after the user selects spendable content source.If when to have spendable content source be a plurality of, search server sent to each content source to search condition respectively.Content source is searched for according to search condition, and Search Results is returned search server after receiving the search condition of search server transmission.For example, detailed process is:

Is the searching interface of content source: http://www.example.com/search? q={searchTerms};

Suppose that the search condition that extracts is " song A " from searching request, is the http request that search server is submitted to content source: http://www.example.com/search? q=song A; Content source will be returned the relevant search result of " song A ".

S604: the Search Results that search server received content source is returned.

S605: search server sends Search Results to the user.

In the another embodiment of the present invention, the user does not carry out the user to search server and registers classification, and content source is registered classification according to the embodiment as Fig. 4 correspondence.The searching request that the user submits to can be passed through third-party network, for example: can be through the network of mobile operator; The third party submits to search server in the lump to user profile and searching request.After search server received user profile and searching request, user profile can comprise ARPU value, cell-phone number type, in the net time, to information such as the paying of search service, user integral.Search server is selected spendable content source according to user profile, and the mode in concrete chosen content source and the embodiment of Fig. 6 correspondence are the same.Search server is searched for according to the content source of selecting; Search server receives the Search Results return and Search Results is sent to the user.

In embodiments of the present invention, after the user proposed searching request, search server was selected operable other scope of content source level of user according to user's rank, and selects spendable content source in this rank content source scope.Search server sends searching request to these spendable content source, and receives the Search Results that returns.Search server is to same search condition, and the rank difference according to the user can search different Search Results, and the searching requirement that this has just realized user individual has ensured user's experience.

In another embodiment of the present invention, content source is not carried out classification, but each content source all can only be by the user of certain several rank use, search server is selected the scope of the operable content source of this user class by user class.For example: content source A can only be used by the one-level user, content source B can only be used by secondary and one-level user, and content source C can only be used by three grades, secondary and one-level user, and user a is a secondary user, when at this moment the user searches for, can only chosen content source B and content source C search for.

The another kind of searching method of the embodiment of the invention as shown in Figure 7.The difference of the embodiment corresponding with Fig. 6: search server is not to select the spendable content source of this user according to user class, but according to the additional information in the searching request select this this search for spendable content source.Specifically comprise:

S701: search server receives the searching request that the user submits to.

Behind the log-on message in search server received content source,, content source is set a rank according to log-on message.Its process is specially:

If pay imformation then is set at levels of payment to content source for paying in the log-on message of content source.If pay imformation is free in the log-on message of content source, then content source is set at free rank.

Search server is preserved the paying or the free information of content source, as table 6:

Content source	Pay/free
		Content source 001	Pay
Content source 002	Freely
		Content source 003	Pay
??............	??............

Table 6

The user submits to searching request to arrive search server.Carry search condition and additional information in the searching request that the user submits to.Additional information can be for additional search restrictive condition, as parameters such as " reception charged content ", " receiving only charged content ".The user receives only free content under the implied terms; If additional information is " a reception charged content ", the expression user is ready to receive free and pay content; If additional information be " receiving only charged content ", represent that the user only is ready to receive pay content.

The user submits searching request to, can pass through third-party network, and wherein the third party can be mobile operator.The third party submits to search server in the lump to user's number information and searching request.

S702: search server receives user's searching request, and according to searching request, for the user selects spendable content source;

After search server receives user's searching request, from searching request, extract additional information, according to the search additional information, obtain the operable content source of user, for example: if do not contain additional information in the searching request, perhaps additional information is " acquiescence ", and then for this search, the user is only to use free content source.If the additional information that contains in the searching request is " reception charged content ", then for this search, the user can use and pay and free content source.If the additional information that contains in the searching request is " receiving only charged content ", then for this search, the user is only to use the content source of paying.
