Abstract: A node of a communication network determines a hash-based sketch. The sketch may for example correspond to a Count-Min (CM) sketch. The sketch summarizes a number of occurrence of an event for a group of UEs. Further, the node receives information representing the number of occurrence of the event for said group of UEs from one or more further nodes of the communication network, e.g., in a further hash-based sketch. The node updates the sketch with the information received from the further and provides the updated sketch to the further nodes.

Abstract: Methods and systems are disclosed for anonymizing a dataset that correlates a set of entities with respective attributes. The method comprises determine clusters of similar entities. Determining the clusters comprises (1) partitioning the entities into a first group with similar attributes to one another and a complement group of entities with similar attributes to one another and (2) recursively repeating the partitioning on the groups until every group meets one or more criteria. The partitioning a group comprises choosing a reference entity from the group, determining a symmetric set of attributes based on the reference entity attributes and on an average of the group's attributes, and assigning each entity to the first or second group depending on whether its attributes are more similar to those of the reference user or to those of the symmetric set.

Thereby, the second data user is enabled to estimate and use the second observation report depending on its reliability as indicated by the rating information.

Abstract: Method performed by a network node of a serving cell. The method is for configuring a user equipment served by the serving cell with a set of values of an offset parameter for triggering handover towards a neighbor cell. The network node and the user equipment operate in a cellular network. The network node configures the user equipment with the set of values of the offset parameter, depending on an uplink-downlink traffic ratio of the user equipment. The user equipment receives from the network node the set of values of the offset parameter for triggering handover towards the neighbor cell. The user equipment uses the received set of values of the offset parameter to expand or shrink the coverage area of the one of the serving cell and the neighbor cell that is the smaller cell, depending on the uplink-downlink traffic ratio distribution of the user equipment.

Abstract: A method and a server (300) for handling database queries directed to a semantic database (302) with stored information according to a preset ontology structure and annotated as element identifiers comprising triplets with a subject, a predicate and an object. In the server (300), a data analyser (300a) collects statistics from the database and defines semantic rules from the information in the database. When a database query is received with a first set of sub-queries, a query optimiser (300c) rewrites the query as a second set of sub-queries in the triplet format based on any of the ontology structure, the collected statistics and the defined rules. A Reduction Rate RR is also calculated for the sub-queries relating to the number of distinct subjects and objects appearing in the database with the predicates of the sub-queries. The sub-queries of the second set are finally provided as a modified query in an order according to decreasing Reduction Rates for execution in that order when searching the database.

Abstract: The invention provides an improved recommender system that includes a client device or service provider server, a trusted function handler module and a recommender module. The recommender system functions to protect the privacy of user rating information maintained by the node (i.e., client device/server) by having the node transform the user rating information using a specific function selected by the function handler and then provide the transformed user rating information to the recommender module. In this way, privacy of the user rating information is maintained because the original user rating information will be unknown to a recommender module.

Abstract: A method and arrangement for creation of a customized recommendation of items in a user device (200) in communication with a recommendation system (202). The recommendation system obtains (2:2a) ratings of items for a public recommendation based on public user data (202a) and obtains (2:2b) attribute-related weight information for said items with item-specific weight values for a plurality of attributes pertaining to user characteristics. The ratings of items in the public recommendation and the weight information are sent (2:3) to the user device which then modifies (2:4, 2:4a) the public recommendation into a customized recommendation by selecting attributes valid for a current user based on said private user data, and applying the weight values of the selected attributes only to the received ratings of items. The non-valid attributes are thus disregarded. Thereby, new item ratings are obtained which have been adapted to the characteristics of this particular user.

Abstract: A user device (110) is connected to a web server (120) via a network (130). An owner (140) communicates with the web server and has a communication channel (141) to the user device. The owner initiates an URI assignment request to the user device and obtains the device credentials via the communication channel (141). The owner provides the credentials to the web server via a communication channel (121). The web server sends the credentials to the user device which compares the credentials with its memory (110a) and replies with the URI status. The web server sends the URI assignment to the user device which accepts and confirms back to the web server which sends a locking message to the user device. The owner can revoke the URI using a password that is verified by the user device, which deletes the URI. An advantage is that the owner can acquire the URI without being the owner of domain.
