## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application is a continuation-in-part application of International Application PCT/CN2013/076486, filed May 30, 2013, and claims foreign priority to application No. 201210178965.0, titled “User Recommendation Method and System in SNS Community”, filed to China Patent Office on Jun. 1, 2012, which are incorporated herein by reference in their entireties.


FIELD OF THE INVENTION
The present invention relates to social networking service fields, and more particularly, to a user recommendation method and system in an SNS community, and a computer storage medium.
BACKGROUND OF THE INVENTION
Social networking service (referred to as “SNS”) is an internet application service to help people establish a social network. An SNS community is a website or a platform that provides the social networking service. People make friends in a SNS community, and immediately share information and knowledge with the others. The SNS goes deeper and deeper in people's life, work and study.
Along with the network technology development, the SNS community has rapidly become a general platform including multiple functions of making friends, expanding relationship circle, showing self, sharing information, gaming and entertaining, etc. According to different particular functions, kinds of the SNS community can be different. For example, some SNS community has blog function and users can create their own-feature space in this SNS community. Other SNS community emphases the function of expanding user relationship circle to provide the users with a making-friend platform. Along with the information technology development and continuous update of network applications, the users' needs change continuously. Therefore, SNS communities having new functions derive from old SNS communities to satisfy the users' needs.
The SNS community generally has a user recommendation function, i.e., other users that a user may be interested in can be recommended to the user. The user recommendation function of the SNS community can help the user to find other users that he/she may be interested in, thereby expanding relationship circle of the user effectively to avoid losing community users. The conventional user recommendation method in the SNS community is to associate the SNS community with the instant messaging. If users are friends in the instant messaging, then the friend in the instant messaging is recommended to the user in the SNS community.
However, the conventional user recommendation method in the SNS community only recommends friends in the instant messaging to the user. This results in a small amount of recommendation users and may miss many persons who the user is more interested in. Therefore, the conventional user recommendation method in the SNS community lowers efficiency of expanding user relationship circle.

DETAILED DESCRIPTION OF THE EMBODIMENTS
As shown in FIG. 1, in an embodiment, a user recommendation method in an SNS community includes the following steps:
Step S102, obtaining an interaction record between a first user and a second user in a first community.
In an embodiment, number of the first community can be more than one and kind of the first community can also be more than one, such as microblog platform, forum community, etc. In step S102, a number of interaction records of the first user and the second user in the SNS community can be obtained.
In an embodiment, interaction operations between users in the first community can be pre-recorded, and the interaction records between the users are saved.
In an embodiment, the interaction operation is any read operation that a user reads relevant information of other user in the community and any write operation that the user applies to the relevant information of the other user in the community.
In an embodiment, the interaction record includes at least one operation record selected from the group consisting of visiting, commenting, replying, giving a like, forwarding, transmitting, and sharing operations, etc.
Step S104, generating an interaction frequency of the first user and the second user according to the interaction record.
In an embodiment, the user applying one read-operation to the relevant information of other user in the community, or applying one write-operation to the relevant information of other user in the community can be recorded as one interaction operation between the users.
Specifically, number of the interaction operation is counted in a specific period of time. The interaction frequency of the first user and the second user is calculated as a ratio of the number of the interaction operation to the specific period of time. In the embodiment, the number of the interaction operation is equal to number of interaction record.
Step S106, calculating familiarity of the first user and the second user according to the interaction frequency.
In an embodiment, the familiarity and the interaction frequency is preset as a direct-proportional relationship. The higher the interaction frequency of the first user and the second user is, the higher the familiarity of the first user and the second user is. After the interaction frequency of the first user and the second user is obtained, the familiarity of the first user and the second user can be increased according to the interaction frequency and the direct-proportional relationship.
Step S108, recommending the second user whose familiarity with the first user exceeds a threshold to the first user in a second community.
In an embodiment, the second user is recommended to the first user as a person who the first user may possibly know.
In an embodiment, a list including second users whose familiarities with the first user exceed the threshold is shown to the first user, allowing the first user to choose a second user that he/she wishes to add a friend, listen in or concern. Further, the second user that the first user chooses is obtained. The chosen second user is added to friends of the first user or added to listening-in or concern subjects of the first user.
In an embodiment, the step S108 can choose a second user that is not a friend of the first user in the second users whose familiarities with the first user exceed the threshold in the second community and recommends the chosen second user to the first user as a person who the first user may possibly know. In the embodiment, a second user that is a friend of the first user is filtered, avoiding repeatedly recommending a friend or a user that the first user has already listened-in or concerned to the first user.
In the user recommendation method in the SNS community, the users in the first community and the second community are registered users.
In an embodiment, the first community and the second community share a user verification information database. User identities of the same user in the first community and in the second community are the same. The user identity of the user in the first community is called a first community user identity of the user. The user identity of the user in the second community is called a second community user identity of the user.
In another embodiment, user identities of the same user in the first community and in the second community are different. The first community and the second community share a user identity corresponding relationship database. The user identity corresponding relationship database stores a corresponding relationship between the first community user identity and the second community user identity of the same user.
In the embodiment, the step S108 includes: obtaining a second community user identity of the first user; finding a first community user identity of the first user according to the second community user identity of the first user and the corresponding relationship; obtaining a first community user identity of the second user corresponding to the first community user identity of the first user and whose familiarity with the first user exceeds the threshold; finding a second community user identity of the second user according to the first community user identity of the second user and the corresponding relationship; showing a list of second users found corresponding to the second community user identity to the first user.
The user recommendation method in the SNS community generates the interaction frequency of the first user and the second user according to the interaction record between the first user and the second user in the first community, calculates familiarity of the first user and the second user according to the interaction frequency of the first user and the second user, and recommends the second user whose familiarity with the first user exceeds the threshold to the first user in the second community. A high familiarity of the first user and the second user indicates that the second user is a person who the first user may possibly know. The method calculates the familiarity between the users in other community, and recommends other users to the user in the current community according to the familiarity, and expands information sources that can be used for determining which users are persons who the user may possibly know, thereby obtaining more persons who the user may possibly know and improving the efficiency of expanding user relationship circle.
In an embodiment, the user recommendation method in the SNS community further includes a step: generating closeness of the first user and the second user according to a user relationship chain in the first community and a user relationship chain in the second community.
Specifically, the user relationship chain in the first community is a relationship chain established between users in the first community and includes a social relationship, such as a friend relationship, a listening-in relationship or a concern relationship, etc. The user relationship chain in the second community is a relationship chain established between users in the second community. Moreover, if the first user and the second user have a social relationship in the first community or in the second community, then the closeness of the first user and the second user is increased. In the embodiment, the step S106 includes: calculating the familiarity of the first user and the second user according to the interaction frequency and the closeness of the first user and the second user.
Specifically, in an embodiment, a weight corresponding to the interaction frequency of the first user and the second user, and a weight corresponding to the closeness of the first user and the second user are preset. The step S106 increases the familiarity of the first user and the second user according to the interaction frequency and the closeness of the first user and the second user and the weights corresponding to the interaction frequency and the familiarity. The higher the interaction frequency and the closeness of the first user and the second user are, the higher the familiarity of the first user and the second user is.
As shown in FIG. 2, in an embodiment, the step of generating the closeness between the users according to the user relationship chain in the first community and the user relationship chain in the second community includes:
Step S202, determining which relationship of the following relationships of the first user and the second user is in the first community according to the user relationship chain in the first community: the second user being a friend of the first user, the second user being a twice friend of the first user, the second user being a user that the first user listens in or concerns.
The second user being the twice friend of the first user means that the second user is a friend of a friend of the first user.
Step S204, determining whether the second user is the twice friend of the first user in the second community according to the user relationship chain in the second community.
Step S206, increasing the closeness of the first user and the second user according to a preset weight, if the second user is the friend of the first user, or the second user is the twice friend of the first user, or the second user is a user that the first user listens in or concerns in the first community, or the second user is the twice friend of the first user in the second community.
In an embodiment, a weight corresponding to a relationship of the first user and the second user is preset. Preferably, rank of weights corresponding to the following relationships is set from high to low: the second user being a friend of the first user in the first community, the second user being a user that the first user listens in or concerns in the first community, the second user being a twice friend of the first user in the second community, the second user being a twice friend of the first user in the first community. The closeness of the relationship of the first user and the second user in the above rank descends and the weight corresponding to the relationship also descends, thereby obtaining a more accurate closeness of the first user and the second user.
The user recommendation method in the SNS community generates closeness between the users according to the user relationship chain of the current community and the user relationship chain of other community, calculates familiarity between the users according to the interaction frequency between the users and the closeness of the users, recommends a person who the user may possibly know to the user in the current community according to the familiarity between the users. The method calculates the familiarity between the users according to multi-aspect information of the current community and the other community and can more accurately obtain an actual familiarity between the users, thereby improving the accuracy of recommending a person who the user may possibly know to the user.
In an embodiment, the user recommendation method in the SNS community further includes a step: calculating similarity of the first user and the second user according to personal data of the first user and the second user in the first community and personal data of the first user and the second user in the second community.
Specifically, if the personal data of the first user are the same as or similar to the personal data of the second user in the first community, or the personal data of the first user are the same as or similar to the personal data of the second user in the second community, then the similarity of the first user and the second user is increased accordingly.
Specifically, in an embodiment, the personal data include hometown, education history, work history, current residence, etc. If the hometown, the education history, the work history, and the current residence of the first user are the same as or similar to the hometown, the education history, the work history, and the current residence of the second user in the first community or in the second community, then the similarity of the first user and the second user can be increased according to a preset weight.
In the embodiment, the step S106 includes: calculating the familiarity of the first user and the second user according to the interaction frequency, the closeness and the similarity of the first user and the second user.
Specifically, in an embodiment, weights corresponding to the interaction frequency, the closeness and the similarity of the first user and the second user are preset respectively. The familiarity of the first user and the second user is increased according to the interaction frequency, the closeness, the similarity and the weights corresponding to the interaction frequency, the closeness and the similarity. The higher the interaction frequency, the closeness and the similarity of the first user and the second user are, the higher the familiarity of the first user and the second user is.
The user recommendation method in the SNS community calculates similarity between the users according to the personal data of the users in the current community and other community, calculates the familiarity between the users according to the interaction frequency, the closeness and the similarity between the users, and recommends a person who the user may possibly know to the user in the current community according to the familiarity between the users. The method calculates the familiarity between the users according to multi-aspect information of the current community and other community and can more accurately obtain an actual familiarity between the users, thereby improving the accuracy of recommending a person who the user may possibly know to the user.

In an embodiment, the user applying one read-operation to the relevant information of the other user in the community, or applying one write-operation to the relevant information of the other user in the community can be recorded as one interaction operation between the users.
Specifically, the interaction frequency generating module 304 counts number of the interaction operation in a specific period of time and calculates the interaction frequency of the first user and the second user as a ratio of the number of the interaction operation to the specific period of time.
The familiarity calculating module 306 is configured to calculate the familiarity of the first user and the second user according to the interaction frequency.
In an embodiment, the familiarity and the interaction frequency are preset as a direct-proportional relationship. The higher the interaction frequency of the first user and the second user is, the higher the familiarity of the first user and the second user is. The familiarity calculating module 306 increases the familiarity of the first user and the second user according to the interaction frequency and the direct-proportional relationship.
The recommending module 308 is configured to recommend the second user whose familiarity with the first user exceeds the threshold to the first user in the second community.

Further, the recommending module 308 can obtain the second user that the first user chooses and adds the chosen second user to a friend of the first user or adds to listening-in or concern subjects of the first user.
In an embodiment, the recommending module 308 can choose a second user that is not a friend of the first user in the second users whose familiarities with the first user exceed the threshold in the second community and recommend the chosen second user to the first user as a person who the first user may possibly know. In the embodiment, the second user that is a friend of the first user is filtered, avoiding repeatedly recommending a friend or a user that the first user has already listened-in or concerned to the first user.
In the user recommendation system in the SNS community, the users in the first community and the second community are registered users.
In an embodiment, the first community and the second community share a user verification information database. User identities of the same user in the first community and in the second community are the same. The user identity of the user in the first community is called a first community user identity of the user.
