Abstract: For controlling synchronization between a multimedia flow and a related social network thread, a device able to capture the multimedia flow and the social network thread selects (S1) a time interval, determines (S2) a list of multimedia keywords associated with the multimedia flow and determines (S3) a list of social keywords associated with the social network thread, each multimedia keyword and each social keyword being associated with a timestamp.

Abstract: For an association of a social network message written by a user in a social device (SD) with a related multimedia flow received by a broadcast receiver device (BRD), a correlation device (CD) detects the presence of the broadcast receiver device (BRD) receiving a multimedia flow in the same location as the social device (SD), extracts social keywords (SK) from a social message written by the user, requests the broadcast receiver device (BRD) for metadata about the received multimedia flow and extracting multimedia keywords (MK) from the metadata of the multimedia flow, provides a correlation coefficient (CoC) as a result of a probabilistic measure between the multimedia keywords (MK) and the social keywords (SK), and retrieves an identifier (OH) of a social network thread associated with the multimedia flow. If the correlation coefficient (CoC) is greater than a first predefined threshold, the retrieved identifier is added to the text of the social message.

Abstract: In one example embodiment, the learning content management system includes a processor configured to determine a local level of understanding for a learning object based on a plurality of received inputs. The local level of understanding indicates a collective understanding level of the learning object by a plurality of users. Each of the plurality of received inputs indicates a level of understanding of the learning object by one of the plurality of users. The processor is further configured to determine a global level of understanding based on the determined local level of understanding.

Abstract: A user preference profile apparatus comprises a receiver (301) which receives preference indications from a plurality of devices (101-105) which have different device characteristics. The received preference indications are implicit preference indications reflecting user actions for content items. A relation processor (305) provides device dependent relations for devices where each device dependent relation defines a calculation of a device content item preference as a function of at least one preference indicator from the corresponding device. A preference processor (303) generates a device content item preference for content items and devices in response to received preference indications for the content items and devices and the corresponding device dependent relation. A user profile processor (307) then modifies a user preference profile in response to the content item preferences.

Abstract: An alert management apparatus (100) comprises a presentation item data store (107) providing first description data associated with a plurality of presentation items, such as audio clips. The alert management apparatus (100) further comprises an alert data store (103) storing second description data associated with an alert, such as an alert for a content item. An association processor (109) is coupled to the presentation item data store (107) and the alert data store (103) and is arranged to select a presentation item of the plurality of presentation items for the alert in response to the first description data and the second description data. For example, a presentation item matching the genre, artist and or title of a content item of the alert may be selected. A presentation processor (111) then presents the selected presentation item to a user when the alert is activated. The invention may allow an automatic customisation of alert notifications.

Abstract: The invention relates to personalizing an application such as a content search and retrieval application. An ontology store (301) provides a multi-user ontology for a plurality of users. The multi-user ontology can be a standardised ontology. A user preference processor (303) provides a user preference profile for a first user and a concept processor (305) generates at least one additional concept for the multi-user ontology in response to the user preference profile. The additional concept is a predecessor concept for a group of concepts that have preferences in the user preference profile which meet a first criterion, such as a requirement that the concepts have sufficiently high preference values. An ontology processor (307) then generates a personalized ontology for the first user by adding the at least one additional concept to the multi-user ontology. An application processor (309) then proceeds to adapt the application for the first user in response to the personalised ontology.

Abstract: The invention relates to generation of a user profile for applications and/or services such as e.g. recommendation of content items. Initially, a first user profile is generated at a first user device for a first user. The first user device furthermore stores user contacts for the first user with the user contacts being associated with a social network of the first user. A set of user devices associated with a set of user contacts of the stored user contacts is then determined and at least part of the first user profile is transmitted to this set of user devices. At least one user device generates user profile feedback which is transmitted back to the first user device. The first user device then modifies the first user profile in response to the received user profile feedback. The invention may allow a fast generation of an initial user profile with improved accuracy.

Abstract: An access unit (107) detects a service access (201) suitable for group operation and in response transmits (203) a group formation request to a plurality of applications. The applications decide whether to join the group (205) and the access unit (107) receives a group join indication from the applications deciding to join (207). Each group join indication comprises application constraint data in response to which the access unit (107) determines group constraint data (209) indicative of the constraints of the group of applications. The access unit (107) then accesses (211) a service using the group constraint data. The access unit subsequently receives service data (213) which is forwarded (215) to the individual applications. The invention may provide group based services based on services and/or applications designed for single users.

Abstract: A user device comprises an access interface (109) for accessing a web service by exchanging information with the web service over the Internet (105). An application processor (107) executes a user application accessing the web service through the access interface (109) and the Internet (105). The application processor (107) is connected to an ontology processor (111) which determines an ontology associated with at least some of the information exchanged with the web service. For example, the ontology may relate to a data structure of data objects communicated between the application processor (107) and the web service. The user device (101) further comprises a preference detector (113) which determines a user preference indication in response to the ontology and the exchanged information. The preference detector (113) is connected to a preference processor (115) which determines a user preference in response to the user preference indication.
