20130138663 | System or Apparatus for Finding Influential Users - Embodiments of the invention disclose a method, identifier and a computer program product for identifying influential users among a group of users associated with a communication network. The disclosed method includes selecting two or more ranking models from a plurality of ranking models such that each ranking model provides scores to the users in the group based on a usage data of the users, calculating a weighing factor for each of the selected ranking models, generating an aggregate score for each user using the weighing factor and the score provided by each one of the selected model such that based on the aggregate score, the influential users among the group of users are identified. | 05-30-2013 |
20150039539 | Method and Apparatus For Propagating User Preference Information in a Communications Network - A method for propagating user preference information in a communications network, in which the user preference information may be available for a subset of users within the network. The method comprises generating individual user attribute vectors, based on user historical data and estimating user preference information. The method further comprises defining a community structure for the network and generating a stacked representation for users, the representation comprising the user attribute vector augmented with an aggregated vector of estimated user preferences of members of the user's community. The method further comprises learning a function relating the stacked representation to user preference, using the subset of users, and applying the learned function to users outside the subset. | 02-05-2015 |
20150188783 | METHOD AND APPARATUS FOR DETECTING COMMUNITIES IN A NETWORK - A method for detecting communities in a network comprises the steps of defining an internal scoring function (IS) for a community, wherein the internal scoring function quantifies an internal quality of the community, and defining an external scoring function (ES) for a community, wherein the external scoring function quantifies an external quality of the community. A community scoring function (IE) for a community is determined, wherein the community scoring function comprises a product of the internal scoring function and the external scoring function. A network scoring function is determined, wherein the network scoring function is based on the community scoring functions of communities in the network. The network scoring function is used by a maximization algorithm, for example a greedy maximization algorithm, for detecting a community in a network. | 07-02-2015 |
20150234831 | FEDERATED DATABASE SYSTEM - Query handling devices in a federated database system and related methods and computer program products for handling queries in the federated database system are disclosed. The query handling device receives database queries directed towards a group of databases from several applications and filters the queries based on common query rules such as common query syntax, investigates the queries that have passed the filtering, and sends the investigated queries to the databases. The investigation includes prioritising between at least some queries according to a query prioritisation scheme. The prioritised queries are sent according to the query prioritisation scheme. | 08-20-2015 |
20150236910 | USER CATEGORIZATION IN COMMUNICATIONS NETWORKS - There is provided categorization of users in a communications network. Information is acquired from a plurality of information sources in a communications network. The information is associated with a plurality of users of the communications network and represented by a multi-relation network representation. The multi-relation network representation comprises a plurality of node types and relationship types. At least one categorization criterion is acquired. A categorization routine is repeatedly to performed to determine a relation between the users. The users are categorized according to the determined relation. | 08-20-2015 |
20150263925 | METHOD AND APPARATUS FOR RANKING USERS WITHIN A NETWORK - A method for ranking users within a network is disclosed. The method includes the steps of generating a ranking measure for each of a plurality of users within the network, monitoring network performance of the plurality of users, and identifying occurrence of conflict between ranking measure and network performance of a user. The method further includes the steps of resolving the conflict by reference to an authority and using information from the resolved conflict to inform subsequent generation of ranking measures. Also disclosed are a computer program product for carrying out a method of ranking users within a network and an apparatus configured to rank users within a network. | 09-17-2015 |
20150301981 | PRE-BUFFERING OF CONTENT DATA ITEMS TO BE RENDERED AT A MOBILE TERMINAL - The present invention relates to methods and devices for pre-buffering one or more content data items to be rendered at a mobile terminal. In a first aspect of the present invention, a mobile terminal ( | 10-22-2015 |
20150339361 | EXPOSING DATA TO QUERY GENERATING APPLICATIONS USING USAGE PROFILES - A query handling arrangement is disclosed for a federated database system. The database system includes data storing applications configured to store data in corresponding databases. The query handling arrangement includes a query handling device that receives a database query from a query generating application concerning the obtaining of data from the databases, obtains usage profiles regarding allowed use of the data in the databases provided by a usage profile announcing device, investigates the usage profiles, obtains data from the databases according to the obtained usage profiles, and responds to the query with the obtained data. | 11-26-2015 |
