20110125767 | System and Methods for Updating User Profiles and Providing Selected Documents to Users - The present invention provides an improved recommender system. In some embodiments, the recommender system automatically builds a user profile for a user based solely on the action or actions the user takes with respect to certain documents and the contents of the documents. That is, the profile is based on implicit ratings. In addition to maintaining a user profile for each user, each document in a set of documents will have its own document profile, which is also referred to as a document vector. Advantageously, in some embodiments, the user profile will consist of the same attributes as the document vectors. This advantageous feature enables the recommender system to compare users and documents in order to generate recommendations. | 05-26-2011 |
20110179043 | Double Weighted Correlation Scheme - A method is provided for determining a correlation between a reference user and another user on the basis of two sets of ratings, where each rating is associated with a respective user. In response to a trigger,user ratings associated with the reference user and user ratings associated with the other user are collected, and all co-rated items of these two sets are correlated in the basis of an adjusted cosine correlation function which is weighted by a first and a second weighting function. The correlation is then stored and may be repeated for a plurality of users. The stored correlations may be used e.g. for ranking purposes. | 07-21-2011 |

20120203660 | CO-OCCURRENCE SERENDIPITY RECOMMENDER - Methods, devices, and computer-readable media described herein may provide a recommender system that may increase the serendipity associated with a recommendation. The recommender system omits obvious co-occurred items, rare items, and limits a number of co-occurred items associated with an item table. Local and global weighting values may be calculated to derive a co-occurrence weight. The co-occurrence weight may be compared to maximum and minimum threshold co-occurrence values to omit obvious and rare co-occurred items. | 08-09-2012 |
20120246736 | SYSTEM AND METHODS FOR PROTECTING THE PRIVACY OF USER INFORMATION IN A RECOMMENDATION SYSTEM - 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. | 09-27-2012 |
20130046761 | Method and Apparatus for Social Tagging of Media Files - Media tagging is significantly improved by fusing subjective, user-specific tags with collaborative, community based tags. Users share multimedia metadata tags in a network of users, to improve automatic tag generation for personal multimedia collections without compromising media privacy. In one method, a combined set of annotation tags is suggested to a user, for use in annotating a given media file. The combined set includes a first set drawn from a private, user-specific repository, and a second set drawn from a public, shared repository. In each case, determining which tags are suggested involves computing similarities between an attribute vector associated with the media file being tagged and attribute vectors associated with the tags. An attribute vector is a set of values representing given types of contextual metadata. The similarity determinations may be weighted according to user-specific and shared weights, and these weightings can be adapted to reflect user and community preferences. | 02-21-2013 |
20130066872 | Method and Apparatus for Organizing Images - A method and apparatus are defined for organizing a plurality of digital photos. The method comprises the steps of identifying a group of digital photos, receiving a number defining how many clusters to be formed from the group, receiving profile information to be used for clustering the digital photos into the number of clusters, clustering the group of digital photos according to the profile information, and identifying representative digital photo(s) of the clusters from the clustered digital photos based on the profile information. | 03-14-2013 |

20130268664 | Method and Network Node for Providing Dynamic Subscriber Profiling Information - In the embodiments of the present invention, a network node in an operator network is introduced. The network node is an analysis component configured to analyze the subscriber behavior based on the internet traffic data within the network. The network node is configured to provide a dynamic profile of the subscribers based on the current and past internet traffic. The dynamic profile may be used by other applications in the operator network or third parties. For example, a content provider can take a decision on what content to provide to a certain subscriber, based on dynamic subscriber profile information of this certain subscriber received from the network node according to the embodiments of the present invention. Another example is that an operator can use the dynamic subscriber profile when selecting commercial offers to his own subscribers e.g. when a subscriber has a new music mobile when visiting music sites. | 10-10-2013 |
