Abstract: A method and device for extracting relationship circle of members in SNS network is disclosed. The method includes: (a) selecting target people in the SNS network; (b) analyzing relationship chains of the target people, and extracting a relationship circle of the target people from the relationship chains according to feature filtering conditions. The device includes a target people selection module for selecting the target people in the SNS network; a relationship circle extracting module for analyzing the relationship chains and extracting the relationship circle from the relationship chains according to the feature filtering conditions. Applying the method and device can provide persons who can meet the designated features and their relationship in the SNS network; using the relationship circle of the target people can find out valuable relationship chain information, enable accurate search and transmission of information, and facilitate promotion and cooperation of business activities.

Abstract: A method and system for transmitting information based on social network is provided in the present invention, in order to solve the problem that information transmission within users of a social network may cost high resources. The method includes: calculating information transmission capacity of an obtained user identity according to user information corresponding to the obtained user identity; storing user identities of which transmission capacities are greater than a predetermined threshold into an initial seed user queue; and transmitting information to be sent to a client of which the user identity is stored in the initial seed user queue. Since information to be sent is targeted transmitted to users in a social network having relative high transmission capacities, the cost of information transmission within the users will be reduced.

Abstract: Embodiments of the invention provide a method and device for extracting a characteristic relation circle from a network, which relate to compute technologies. The method includes: obtaining user information; specifying characteristics of a characteristic relation circle to be extracted; determining a user set, in which user information of users in the user set matches with specified characteristics, and extracting the determined user set as the characteristic relation circle. The device includes an obtaining module and an extracting module. In the technical solution provided by embodiments of the invention, after extracting a characteristic relation circle from a socialized network, relation chain information of the socialized network may be effectively utilized, and the objectives of effective propagation and accurate searching of information may be achieved.
