Description

The present invention claims to be submitted to the Chinese Patent Office on November 12, 2007, the application number is 200710170325.4, and the invention is entitled "a method, system and device for providing user information". The priority of the application, the entire contents of which is incorporated herein by reference. Technical field

The present invention relates to the field of communications, and in particular, to a method, system and apparatus for providing user information. Background technique

At present, personalized service has become an important means to improve the quality of service. In other words, when providing services to users, if they can provide personalized services based on the user's background knowledge and preferences, then the user's acceptance of the service. Degree and satisfaction will be greatly improved. Therefore, personalized service is used as a development trend in various fields. The premise of providing personalized service is to provide user information such as background knowledge and preferences, and then match the user information with the service to be provided, so as to provide personalized service for the user. It can be seen that the provided user information directly affects the quality of the personalized service provided.

At present, the user often provides the user information according to the user status, that is, the user has different preferences and settings in different states, so the user information is divided into multiple versions according to the state condition, for example, according to the location. It can be divided into a public place state, an office place state, and a home state, and can be classified into a leisure state or a work state according to the degree of tension. Which version of user information should be used when providing the service, depending on which version of the user information associated with the status condition is true. In these systems, there is a simple correspondence between state conditions and user information. For example, in the prior art state condition and user information association structure diagram shown in FIG. 1, the user information is divided into a plurality of profile subsets, and each profile subset is associated with zero ( By default) or multiple status conditions (condition), the actual user information is saved in the entity model (Entity Model ). As shown in Figure 1, the profile, condition, profile subset, and Entity Model are each composed of one or more parameters, such as the entity identifier in the profile.

( entitylD ) and entity type ( entityType ) parameters; and condition contains the entity identifier ( entitylD ), context type ( contextType ), context value parameter

(ContextValue ), since the state condition shown in Figure 1 can be represented by a relational expression, the state condition also includes the operator ( operator ). When the current state meets a certain state condition, the profile subset to which the state condition is associated is activated, and only this profile subset is valid. Referring to FIG. 1, a flow chart of a method for providing user information according to a user state as shown in FIG. 2 is given, and a method for providing user information is specifically described. The user information storage component in FIG. 2 is configured to activate a subset of user information corresponding to the current state. When the data requester requests the user information, the user information storage component queries the currently activated user information subset (active subprofile) to obtain the requested User information, and returned to the data requester. Specifically, the following steps are included:

Step 201: The user information storage component subscribes the status of the user to the status provider. When the user status changes, step 202 is performed.

Step 202: The status provider notifies the user of the current state of the information storage component user. Step 203: The user information storage component activates the corresponding subset of user information according to the current state.

Step 204: The data request requests the user information from the user information storage unit.

Step 205: The user information storage component queries the currently activated subset of user information. Step 206: The user information storage component queries the requested user information in the currently activated subset of user information.

Step 207: The user information storage unit returns a query result to the data requester.

Currently, the method of providing user information requires that each state corresponds to a version of user information in advance, and the difference between user information corresponding to different states may be very small, for example: for "in the office (office_work), and" in Meeting (at_meeting) "The user information corresponding to the two cases has only a small difference in settings. If multiple versions of user information are created, there will be a large amount of redundant information between versions.

Therefore, the current method of providing user information will result in a large amount of user information redundancy. Summary of the invention

In view of this, embodiments of the present invention provide a method for providing user information, which can reduce user information redundancy.

The present invention will be further described in detail below with reference to the accompanying drawings.

In the embodiment of the present invention, each user state does not correspond to a complete user information, but uses the upper-lower order relationship between the user states to reorganize the user information corresponding to each state, and each state only corresponds to part of the user information, thereby achieving Reduce the purpose of redundant user information. Therefore, the method provided in the embodiment of the present invention is: acquiring a current state of the user; obtaining at least one upper layer state of the current state by a preset state hierarchy relationship, The state hierarchy relationship is a relationship that represents the order of the upper and lower layers between the states; the user information corresponding to the current state and the user information corresponding to the upper layer state are merged, and the merged user information is provided.

In the schematic diagram of the user information organization based on the state hierarchy relationship shown in FIG. 3, the user information has the following three characteristics:

First, all user information is associated with a User Identification (hereinafter referred to as UID), and a unified UID is used to associate all user status and status corresponding user information, that is, all states can be indexed by UID. And user information corresponding to the status.

Second, the pre-set hierarchical relationship between the user states, the user information corresponding to each state may be different for each user, as shown in Figure 3, according to the location of the user: At work, at home, in public, etc., and then at the at work state can establish a more specific state: outdoor work (office work) Similarly, in the office work state, a specific state can be established, so that the order relationship between the upper and lower layers can be established, for example, the upper state of the work state is the basic information (user - info), and the lower state is Outside work status and office work status.

Third, the user information corresponding to each state can be regarded as a part of the entire user information, that is, each state only corresponds to part of the information, and thus complete user information needs to be obtained through merging. For example, in FIG. 3, the user information corresponding to the at work state has user information for the communication personalized service of the advertisement, the entertainment content, and the instant message, and the office work status corresponds to the call forwarding and ringing communication personalized service. User information. When the current status is office work, you need to combine the user information corresponding to the user-info state, the at work state, and the office work state.

Figure 4-1 is a schematic flowchart of providing user information in the embodiment of the present invention, which specifically includes the following steps:

Step 410: Obtain a current state of the user.

In this embodiment, the current state can be subscribed to the status provider by using the prior art. State. When the user status changes, the status provider notifies the user information management module to acquire the current status of the changed user.

Step 420: Obtain an upper layer state of the current state by a preset state hierarchy relationship.

In this embodiment, the state hierarchy relationship represents the relationship between the order of the upper and lower layers between states. The state hierarchy relationship preset in this embodiment is given in the form of programming, as shown in Table 1:

<status_relation>

</ default >

<user_info>

</user_info>

<at_work>

<child>outside_work</ child>

<child>office_work</ child>

</at_work>

<outside_work>

</ outside- work>

<office_work>

<child>meetingroom</ child>

</ office_work>

</ status- relation>

Table 1: Status hierarchy

In addition to the state elements in Table 1, the parent (parent) is also introduced. The parent state of the state is the state directly above this state, and the child state is the immediate next state of the state, which is greater than 3⁄4. The parent state of the at work state is the user-info state, and the child state is the office work state and the outside work state, to characterize the order relationship between the upper and lower layers.

In this embodiment, when the user information is provided, in addition to the user information corresponding to the current state, the user information corresponding to the ancestor state needs to be inherited, so that the upper state of the current state needs to be obtained from the state hierarchy according to the current state. In the embodiment, at least one upper layer state of the current state is obtained, and the upper layer state of the current state is searched according to the state hierarchy relationship. The following is specifically described in conjunction with the drawings.

Figure 4-2 shows an example of the process of obtaining a list of all the upper-layer states of the current state and the current state in combination with Table 1. As shown in Figure 4-2, the following steps are specifically included:

Step 421: Find the current state in the state hierarchy, and use the current state as the base state (basic-status).

In this embodiment, the current state is found by a path ( status_ relation/current_ status).

Step 422, the basic state is stored in the status list.

Step 423: Find the parent state of the base state in the state hierarchy relationship.

In this embodiment, the parent state of the underlying state is found by the path ( status_ relation/basic_status/parent).

Step 424: Determine whether the parent state of the basic state is found. If it is found, go to step 425. Otherwise, go to step 426.

In step 425, the parent state of the basic_statage is taken as the basic_statal, and the state is found in the state hierarchy relationship by status_ relation/basic_statage, and the process proceeds to step 422.

Step 426, outputting a list of states consisting of all the base states.

It can be seen from step 421 to step 425 that the output status list contains all the upper layer states of the current state in addition to the current state.

The output status list can be in the form of a queue or a stack. The order of the states in the output status list may be either the order of the current state (or lower layer state) to the upper state (or general state) or the order of the upper state to the current state. It is assumed that the current state obtained in this embodiment is office work, and the upper state thereof includes at work and user-info. Return to Figure 4:

Step 430: Combine the user information corresponding to the current state and the user information corresponding to the upper layer state.

In this embodiment, the method for merging user information includes: according to the order of the upper and lower layers between the states, the user information corresponding to the current state sequentially inherits the user information corresponding to all the upper layer states. In the inheritance of the user information corresponding to the upper layer state, simple re-use can be performed, that is, the user information of the upper layer is completely referred to, and no modification can be made, and the modification can also be made on the basis of inheritance. In this embodiment, in the case of inheritance When the data item in the user information is unique in the current state and the upper layer state, the data item of the user information corresponding to the lowest layer state is used as the data item of the merged user information.

4 In this embodiment, the xml document carries the user information, and each state corresponds to a document, and the document name is the state of the user. In this embodiment, the at-work.xml, office-work.xml, and basic-user-info.xml documents may be included, and the documents carry user information and basic user information corresponding to the user at the work, office work status. For all users, there is a unified user profile schema. When the user is in a certain state, the corresponding user profile = the profile of the upper layer and the profile specific to the layer, where o+ indicates the merge. Therefore, when merging the user information corresponding to each state in the status list, it may be necessary to merge multiple xml documents with the same shema from the lower layer to the upper layer, for example, the terminal user with the UID of 000001, when the user is in the office work state, the user corresponds The user profile is: Office work.xmlo+ at work.xml o+Basic— user— info. xml„

The following is specifically described by taking the same xml document merged in two modes (shema) as an example, where two documents are a first document and a second document, respectively, and the first document is a user information document corresponding to a sub-state of the second document. . On the basis of the first document, the elements in the second document user information are merged into the first document, as shown in the example flow diagram of the merged user information document shown in FIG. 4-3, which specifically includes the following steps:

Step 431: Access the second document in a deep traversal manner, and find the first element in the second document. Step 432, traversing the first document in depth, whether the element can be found in the same path in the first document, if it can be found, step 433 is performed; otherwise, step 434 is performed.

In step 433, it is determined whether the element is unique. If the element is unique, the value of the element in the first document is discarded, and the value of the element in the second document is discarded. Step 435 is performed directly. If the element indicates that the element can have different values, go to step 434.

In this embodiment, whether the user information element is unique or not is determined by the restriction of the XML language. When the user data schema does not set maxOccurs or minOccurs for the element, the default element has a unique '1'.

Assume that in this embodiment, the user alias (username_alias) in the user information is different in Basic-user-info.xml and in Office-work.xml.

In Basic-user-info.xml there are:

<username_alias>Bob Albert</username_alias>

In Office.work.xml there are:

<username_alias>Bob</username_alias>

User aliases are unique and conflict when merging username-alias. In this embodiment, the user's lowest level state, that is, the most detailed state is taken as the standard, so when the merge is performed, the username alias in Office work.xml is taken as the merged element, and Basic_user_info.xml is used. Username - alias is discarded.

Step 434, if there is a path where the element is located in the first document, the element and its value are added under the path, otherwise the path of the element and its value are added in the first document.

Step 435: Determine whether the element is the last element in the second document. If not, execute step 436; if yes, execute step 437.

Step 436, accessing the second document in a depth traversal manner, finding the next element of the current element as the current element, and proceeding to step 432.

Step 437, the merge process ends.

Step 440: Provide user information obtained by combining.

It can be seen from the foregoing embodiment that the embodiment of the present invention uses the state hierarchy model to organize user information, and each state only corresponds to part of the user information, and uses the inherited method to reuse. Layer state information reduces a large amount of data redundancy.

When the state is newly added, since each state only corresponds to part of the user information, the workload of organizing the user information can be reduced.

When a data item or element in the user information is falsified, since the user information is inherited in this embodiment, only the lowermost state of the user is taken as the standard, and thus the data modification in each state is not required. It needs to be modified in a state that covers the lowest level that you want to be modified.

Of course, this embodiment can also assume that the number of layers is set in advance, and according to the state hierarchy relationship given in Table 1, the upper layer state of the current state is sequentially searched. At this time, the number of upper layer states obtained is equal to the number of layers set in advance. For example, if the number of layers set is 1 layer, when the current state is office work, the upper state obtained is at work. Then, when the user information is merged in step 430, only the user information corresponding to the office work state and the user information corresponding to the at work state are merged.

FIG. 5 is a schematic structural diagram of a system for providing user information according to an embodiment of the present invention. Referring to Figure 5, the system includes:

The user information storage module 510 stores partial user information corresponding to each state; the user information management module 520 acquires the current state of the user; and obtains the upper state of the current state by the upper and lower hierarchical relationship between the states of the state hierarchy relationship preset; User information corresponding to the current state stored by the user information storage module and user information corresponding to the upper layer state;

The state obtaining unit 522 includes: The first search subunit 525 searches for all upper layer states of the current state according to the state hierarchy relationship when the number of layers is not set in advance;

The second search subunit 526, when setting the number of layers in advance, sequentially searches for the upper layer state of the current state according to the state hierarchy relationship, and the number of the upper layer states is equal to the number of layers.

The user information management module 520 also includes:

The determining unit 524 is configured to determine whether the current state of the merged user is consistent with the current state of the obtained user when the current state of the user is obtained according to the request for receiving the user information, and the judgment result indicates the current state and the acquired state of the merged user. When the current state of the user is inconsistent, the trigger state obtaining unit 522 regains the upper state of the current state. When the judgment result indicates that the current state of the merged user is consistent with the current state of the acquired user, the user information providing module 530 is triggered to directly provide The merging unit 523 merges the obtained user information.

As shown in the above embodiment, the user information management module 520 of the embodiment of the present invention merges the user information stored in the user information storage module 510 according to the obtained current state and the upper state of the current state, and then maps the user information to the user information providing module 530. When the data requester requests the user information, the latest user information can be obtained directly from the user information providing module 530, so that the user information can be quickly provided.

FIG. 6 is a schematic structural diagram of an apparatus for providing user information according to an embodiment of the present invention. Referring to Figure 6, the device includes:

The current state obtaining unit 621 acquires the current state of the user.

The state obtaining unit 622 is configured to obtain an upper layer state of the current state by a preset state hierarchy relationship.

Specifically, the state obtaining unit 622 includes:

The first search sub-unit 625 is configured to find all upper-layer states of the current state according to the state hierarchy relationship when the number of layers is not set in advance;

a second lookup subunit 626, when the layer number is preset, according to the state hierarchy The relationship sequentially searches for an upper layer state of the current state, and the number of the upper layer states is equal to the number of layers.

Depending on the manner of data access, the timing of providing the merged user information is also different. In this embodiment, the merged user information is triggered by the state change, that is, when the state changes, the merged user information is obtained. Upon receiving the user information request of the data requester, the merged user information is directly provided to the data requester. FIG. 7 is a schematic flowchart of a method for providing user information in a mode of triggering merged user information data access by state change. As shown in FIG. 7, the method includes the following steps:

Step 701: The user information management module subscribes the status of the user to the status provider. When the user status changes, step 702 is performed.

Step 702: The status provider notifies the user of the current status of the information management module user. Step 703: The user information management module finds an upper layer state in the state hierarchy relationship according to the current state of the user.

Step 704: The user information management module merges the current state stored by the user information storage module and the user information corresponding to the upper layer state into the user information providing module.

Step 705: The data request sends a user information request to the user information providing module. When an application requires user information, the data requester can directly provide the user information required by the module request to the user information.

Step 706: The user information providing module returns user information to the data requester.

The user information providing module responds according to the request of the application, and the process ends.

In this embodiment, the merged user information may be triggered by the application request, that is, when the user information request of the data requester is received, the combined user information is obtained and provided to the data requester. Before the user information is provided to the data requester, it can be judged again whether the current state has changed. FIG. 8 is a schematic flowchart of a method for providing user information by using a user information request to trigger a merged user information data access method. In the flow shown in FIG. 8, a step of determining whether the current state changes again is performed, and the specific steps are:

Step 801: The data request direction user information providing module sends a user information request. In this embodiment, the parameters requested by the data requester include the UID of the user and the service parameter. Step 802: The user information providing module triggers the user information management module to perform user information combining processing.

Step 803: The user information management module requests the status provider for the current status of the user. Step 804: The user information management module acquires a current state.

In step 805, it is detected whether the current state is consistent with the saved last requested state. If the state has not changed, step 806 is performed; otherwise, step 807 is performed.

Step 806: The state is consistent with the state at the time of the last request, and the user information providing module is notified to use the existing user information.

After step 806 is performed, step 808 is directly executed.

Step 807: The state changes with respect to the last request, and the upper layer state of the current state is re-obtained by the state hierarchy relationship, and the user data corresponding to the current state and the upper layer state in the user information storage module is merged into the user information providing module.

Step 808: The user information providing module returns the user information to the data requester.

The above is only the preferred embodiment of the present invention and is not intended to limit the scope of the present invention. Any modifications, equivalents, improvements, etc. made within the spirit and scope of the invention are intended to be included within the scope of the invention.
