Description

Instant messaging friend recommendation method and device

technical field

The invention relates to the technical field of instant messaging, in particular to a method and device for recommending friends in instant messaging.

Background technique

Instant Messaging (IM) is a network-based communication service, and generally focuses on realizing instant messaging on the network. Instant messaging tools refer to software that realizes network instant messaging services. In a narrow sense, they can also be considered as instant messaging client software. The development of instant messaging tools has been accepted by most netizens, whether it is in daily leisure and entertainment, or in daily work, it has been widely used and has become one of the indispensable tools in the daily life of Internet users. . Therefore, IM users put forward higher requirements on the ease of use, stability and security of instant messaging tools.

IM users can add other IM users who need to be contacted to the friend (or contact) list, know the online/offline status of friends through instant messaging status presentation technology, and initiate real-time dialogues with them at any time, thus achieving instant information. purpose of communication. In order to facilitate IM users to operate contacts, instant messaging tools usually provide friend management functions, including adding, categorizing, and deleting friends.

Under the traditional implementation mode, there are usually two ways to search and discover friends. One is that the IM user realizes the discovery of friends by checking the online IM user list provided by the server of the instant messaging system; Ways, such as friend notices, information disclosed on occasions such as the web, etc., obtain identity information such as instant messaging digital IDs or nicknames of other IM users, and then input the identity information into the server for retrieval, so as to realize the discovery of friends. After discovering, you can directly send a request to be added as a friend to the other party, and the party receiving the request can choose to accept or reject the request.

In the above-mentioned traditional implementation manners, the IM user actively discovers the IM users who may become his friends, and then adds them. In order to expand the way for IM users to find friends, an instant communication tool has also appeared in the prior art to implement friend recommendation for IM users. When an IM user finds a recommended IM user, he can also check the materials of the recommended IM user. If the recommendation is accepted, a request to be added as a friend can also be sent to the recommended IM user. When recommending friends in the prior art, the recommendation is mainly based on the number of common friends between the current IM user and another IM user. For example, there are 10 mutual friends between IM user A and IM user B, and the number of common friends is relatively large, then IM user A plus IM user B can be recommended as friends, or IM user B plus IM user A can be recommended as friends.

However, in practical applications, when recommending friends based on the number of common friends, invalid recommendations often occur. The so-called invalid recommendation refers to a recommendation made to an IM user, but rejected by the IM user, or ignored by the IM user. . Obviously, too many invalid recommendations will not only waste system resources, but also cause IM users to receive too much useless information, which will interfere with the normal use of instant messaging tools by IM users.

Therefore, a technical problem that urgently needs to be solved by those skilled in the art is: how to improve the effectiveness of recommendation when recommending friends.

Description of drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the accompanying drawings required in the embodiments. Obviously, the accompanying drawings in the following description are only some of the present invention. Embodiments, for those of ordinary skill in the art, other drawings can also be obtained based on these drawings without any creative effort.

Fig. 1 is the flowchart of the method provided by the embodiment of the present invention;

Fig. 2 is a schematic diagram of a device provided by an embodiment of the present invention.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

Referring to Fig. 1, the method for recommending a friend provided by an embodiment of the present invention includes the following steps:

S101: Obtain mutual friends of the first IM user and the second IM user;

In the embodiment of the present invention, in order to determine whether to recommend friends between IM user A and IM user B, it is first necessary to extract common friends between the two, and then make further judgments. Wherein, the mutual friend between so-called IM user A and IM user B refers to not only the friend of IM user A, but also the friend of IM user B; IM user B's friend list (the IM user's friend list will be saved on the server side of the instant messaging tool), compare the two friend lists, and both appear in the IM user A's friend list and appear in the IM user B's The IM users in the friend list are mutual friends of the IM user A and the IM user B. In practical applications, there may be multiple mutual friends between two IM users. In this case, all of them may be extracted and used as a basis for judgment respectively.

S102: Obtain first intimacy information between the first IM user and the mutual friend, and second intimacy information between the second IM user and the mutual friend;

In the embodiment of the present invention, in order to recommend a friend to an IM user, the mutual friend between the two IM users can be obtained, and then the intimacy information between the two IM users and the common IM user can be obtained, if If the intimacy between the two IM users and the common friend is high, it proves that the potential intimacy between the two IM users is also high, therefore, friend recommendation can be made between the two IM users . For example, assume that IM user A and IM user B are not currently friends, but the instant messaging tool finds that IM user A and IM user B have a common friend C, and the intimacy between IM user A and IM user C is very high, The intimacy between IM user B and IM user C is also high, which can prove that IM user A and IM user B probably also know each other, or have the same or similar hobbies in certain fields, have common topics, etc. , therefore, the potential intimacy between the two will be relatively high. If a friend recommendation is made between IM user A and IM user B, the probability of accepting the recommendation will be relatively high, thereby reducing the probability of invalid recommendation.

Among them, when obtaining the intimacy information between two IM users, there may be multiple implementation manners. For example, in one of the implementation manners, the interaction between two IM users can be counted, and the intimacy information between the two IM users can be obtained according to the statistical results. Wherein, the so-called interaction situation may refer to a situation in which two IM users establish a conversation through an instant messaging tool (such as chatting through an instant messaging tool), and may also include a situation in which they comment on or reply to information published by the other party, and may also include The case of accessing the other party's personal space, and so on. If there are many or frequent interactions between two IM users, it proves that the intimacy between the two IM users will be relatively high.

In specific implementation, when two IM users become friends with each other for the first time, an initial value can be assigned to the intimacy information between the two; The value of the intimacy information between the two. For example, the intimacy information can be represented by an intimacy level. When two IM users become friends for the first time, an initial value can be given to the intimacy level, and then when the number of interactions reaches a preset condition, the intimacy between the two can be increased. degree level. During specific implementation, the initial value and preset conditions can be flexibly set according to actual needs. For example, in one implementation mode, it can be performed as follows: when IM user A and IM user B become friends for the first time, the initial intimacy level is given as n =1; when the level of intimacy is n, under this level, the number of interactions between IM user A and IM user B reaches 100*5 ^n-1 , and the level of intimacy increases to n+1. For example: when the intimacy between IM user A and IM user B is n=1, and the cumulative number of interactions reaches 100, it will be upgraded to level 2; the cumulative number of interactions at level 2 reaches 500 (the total number of interactions is 600) , upgraded to level 3, and so on.

Of course, in practical applications, the intimacy information between two IM users can also be established based on other information, such as the number of common friends between two IM users, if the number of common friends between two IM users is more , the higher the intimacy between two IM users, and so on. Alternatively, multiple bases for judging the intimacy can also be combined to finally comprehensively determine the intimacy between two IM users, which will not be repeated here. In addition, the intimacy between two IM users is not a fixed value, but may change as the number of interactions between IM users changes. Therefore, the process of recommending friends according to the above method can also be Is a dynamic process, e.g. attempts can be made every so often, etc.

S102: If both the first intimacy information and the second intimacy information meet a preset condition, send recommendation information to add the other party as a friend to the first IM user and/or the second IM user.

As mentioned above, if the intimacy between IM user A and its friend IM user C is relatively high, and at the same time, IM user C is also a friend of IM user B, and the intimacy between IM user B and its friend IM user C is relatively high, then it can be A recommendation is made between IM user A and IM user B to add the other party as a friend. Wherein, when recommending between IM user A and IM user B, the recommendation message may be pushed to IM user A, or to IM user B, or may be pushed to both IM users at the same time. While displaying the recommendation message, the basis for this recommendation can also be displayed to the IM user. For example, when recommending a recommendation message with IM user B as a friend to IM user A, the following information can be displayed to the IM user at the same time: "I am close to you Friend C with a high degree of intimacy is also a friend of the IM user, and your friend C has a relatively high degree of intimacy with the IM user." Of course, the specific description method may not be limited to this. In short, when an IM user receives a recommendation message from a friend and makes a judgment based on the basis of the recommendation, the probability of accepting the recommendation will be relatively high, which improves the effectiveness of the recommendation.

In practical applications, if there are multiple mutual friends between two IM users, the intimacy information between the two IM users and each mutual friend can be obtained respectively, and then the average value is taken as the two Intimacy information between IM users and their mutual friends. For example, assuming that IM user A and IM user B have two mutual friends, namely IM user C and IM user D, the intimacy information a1 between IM user A and IM user C can be obtained first, and the IM user The intimacy information a2 between A and IM user D, and then take the average value of a1 and a2 to get the first intimacy information between IM user A and the mutual friends between them; The intimacy information b1 between user B and IM user C, the intimacy information b2 between IM user B and IM user D, and then take the average value of b1 and b2 to get the common The second intimacy information between friends, and then respectively judge whether the first intimacy information and the second intimacy information meet the preset conditions. Of course, for the above-mentioned situation where two IM users have multiple mutual friends, when obtaining the first intimacy information and the second intimacy information respectively, the intimacy information between the IM user and each common friend can also be obtained. The maximum value of , etc., are not limited here.

In a word, in the embodiment of the present invention, before two IM users are recommended to add a friend, the common friend of the two can be obtained first, and the intimacy information between the two IM users and the common friend can be obtained respectively, If the intimacy information between the two IM users and the mutual friend reaches the preset condition, it proves that the potential intimacy of the two IM users is relatively high, therefore, it is possible to add In this way, the effectiveness of adding friend recommendations can be improved.
