Abstract:
The recommender system uses stored representations of relations between users. Access to an item by one or more first users in the storage system is recorded.. When the recommender system detects a request for a rating of the item from a second user, the recommender system selects at least one of the first users that occurs in a stored relation with the second user. A query message that refers to the second user is then automatically transmitted to enter a rating for the item to a user address associated with the selected first users. Preferably at least one first user is selected for which it has been recorded that it has accessed the item but for which it has not yet given a rating. Preferably, the rating from the first user is passed to the second user via the recommender system, which records the rating for further use. The selection of the first user may be based on recorded data that measures correlation between ratings from the first and second user.
Abstract:
Automatic generation of questions and evaluation answers about a media item is provided for a system such as a video on demand system. A virtually unlimited number of questions can be generated without the need for subjective information. Questions about a media item are generated by selecting a media segment of the media item. At least part of the media item within the selected media segment is shown to a user. The user is asked to indicate a position within the media item where the user thinks that the segment is located. The indicated position is compared to the actual position of the segment to evaluate the answer.
Abstract:
A PVR (A) includes an output (70) wherein a TV channel selected for viewing is output, and a storage device (20) that selectively stores a channel indicator (24) therein. A user interface (60) provides means for selectively loading the storage device (20) with a desired channel indicator (24), and means for selecting a TV channel to be sent to the output (70). A buffer (82) is also included. The buffer (82) automatically records the TV channel output for viewing if the storage device (20) has no channel indicator (20) stored therein, and automatically records that TV channel indicated by the channel indicator (24) when one is stored in the storage device (20) even when the TV channel output for viewing is selected to be different from the TV channel indicated by the channel indicator (24).
Abstract:
The present invention relates to a recommender system and method comprising a first extractor (S200) for applying a first feature extraction algorithm to extract first features characterizing a content of a data input (e.g. webpage) processed by a first application (e.g. Internet browser) running on the system, and a second extractor (S100) for applying a second feature extraction algorithm to extract second features characterizing a content of a database of a second application (e.g. personal TV or movie access) running on the system. Additionally, a comparator (S300) is provided for comparing the first and second features to identify matching items used for the recommendation.
Abstract:
The present invention relates to a method of operating an apparatus for displaying content items on a display, a corresponding computer program for operating an apparatus and to an apparatus (100) for displaying content items on a display (410) that is arranged for being coupled to the apparatus (100). In particular, the present invention relates to an apparatus (100) that is configured to display a plurality of content items in a two-dimensional grid (300) in dependence of a respective relatedness between a selected content item (A) and one of the content items to be displayed. The selected content item is positioned at a center of the display (410) and the related content items are displayed such that associated relatedness values decrease both in left, right, up and down direction with respect to the center position. The invention furthermore relates to a user terminal (400) that comprises such apparatus.
Abstract:
The present invention relates to an apparatus, a method and a computer program product for automatically inserting advertisements into a media stream, wherein subscription information which specifies categories of advertisements to be scheduled for insertion is stored and a category of a target advertisement is determined. Based on the result of the determination those advertisements of a stored list of scheduled advertisements, which according to their subscription information are subscribed to the determined category, are triggered and subjected to a predetermined modification processing selected based on the result of the determination.
Abstract:
The present invention relates to an apparatus, a method and a computer program product for controlling a recommender system, wherein a bias is applied to the output of a recommender in order to favour newly added services and content sources. The bias may decay in time and/or with the number of ratings given to content coming from the new service.
Abstract:
The invention relates to an electronic device and a method for automatic generation of a sorted list of items related to a seed-item. The electronic device comprises a relatedness determinator that is configured to compare said seed item with a plurality of further items and to thus determine a relatedness value for each further item with respect to said seed item. The device device further comprises a clustering engine that is configured to cluster the further items by determining a relative relatedness between (among) the further items. Thus, each further item is assigned to one cluster. The device further comprises a list generator that is configured to generate a sorted result list by sorting the further items according to both, their relatedness value and their belonging (or membership) to a cluster in that once an item is added to the sorted list, the relatedness value depending ranking of the further items in that cluster is at least momentary lowered so as to promote adding items of further clusters thus achieving a higher momentary relatedness value depending ranking to the top of the sorted list.
Abstract:
The present invention relates to an apparatus (100), a video system, a method and a corresponding computer program and a computer readable medium for managing a personal channel (210) of a user (200). The apparatus (100) is configured to identify a personal channel data piece that specifies a content item that the user (200) of the personal channel might not like anymore. The apparatus (100) then suggests (142) to the user (200) to delete the corresponding identified personal channel data piece and thus assists the user (200) in keeping a clear personal channel (210).
