20090033633 | USER INTERFACE FOR A CONTEXT-AWARE LEISURE-ACTIVITY RECOMMENDATION SYSTEM - One embodiment of the present invention provides a system that provides a user interface for a context-aware recommendation system which can be operated with one hand. The user interface includes a touch-screen display and a list of recommendations presented on the touch-screen display. The user interface further includes a plurality of graphic elements presented on the touch-screen display which allow a user to configure preferences associated with the activities. A layout of the leisure activities and the graphic elements allows the user to hold the touch-screen display and perform operations on the leisure activities and/or the graphic elements with one hand. | 02-05-2009 |
20090077000 | METHOD AND SYSTEM TO PREDICT AND RECOMMEND FUTURE GOAL-ORIENTED ACTIVITY - One embodiment of the present invention provides a method for recommending activities to a user. During operation, the system determines an activity-type distribution based on the user's personal profile and/or population prior information, thereby facilitating prediction of future activities for the user. The system further searches for and receives one or more activities based on the activity-type distribution. The system then scores each received activity and recommends a number of activities to be performed by the user in the future and a number of corresponding venues, based on the activity-type distribution and the weight distribution. | 03-19-2009 |
20090187467 | LINGUISTIC EXTRACTION OF TEMPORAL AND LOCATION INFORMATION FOR A RECOMMENDER SYSTEM - One embodiment of the present invention provides a system that recommends activities. During operation, the system receives a piece of content obtained from text or converted to text from speech. The system then analyzes the received content to identify any activity type, indication of willingness to participate in any type of activities, and at least one piece of temporal information, which can be implicitly and/or explicitly stated in the content, and/or one piece of location information associated with the activity type. The system further recommends one or more activities, venues, and/or services that afford or support activities for a user based on the information extracted from the content. | 07-23-2009 |
20090210793 | METHOD AND SYSTEM FOR TRAVERSING DIGITAL RECORDS WITH MULTIPLE DIMENSIONAL ATTRIBUTES - A system facilitates traversing digital records with dimensional attributes. The system stores a number of digital records. The system further associates a respective digital record with a number of attributes, wherein a respective attribute can be specified in a number of levels of abstraction. The system allows a user to control a presentation of the stored digital records based on their attributes. The user can set one or more criteria for the attributes of the digital records to be presented by: specifying the value of at least one fixed attribute of the digital records to be presented, changing at least one non-fixed attribute of the digital records to be presented, and/or specifying a level of abstraction for the fixed and/or non-fixed attribute of the digital records to be presented. The system then presents a set of digital records to the user based on the attribute criteria set by the user. | 08-20-2009 |
20090215536 | LOCATION-AWARE MIXED-REALITY GAMING PLATFORM - One embodiment of the present invention provides a system that facilitates location-aware, mixed-reality gaming platform. During operation, the system determines a layout of a user's surrounding. The system further detects the user's location and/or nearby objects. Next, the system associates virtual content to the determined layout and associates a set of game rules with the virtual content. Subsequently, the system produces a visual and/or audio representation of a game based on the game rules and virtual content to the user, thereby allowing the user to play a game that corresponds to his surrounding and location. | 08-27-2009 |
20100138416 | CONTEXT AND ACTIVITY-DRIVEN CONTENT DELIVERY AND INTERACTION - One embodiment of the present invention provides a computing device that delivers personally-defined context-based content to a user. This computing device receives a set of contextual information with respect to the user, and processes the contextual information to determine a context which is associated with an activity being performed by the user. The computing device then determines whether either or both the context and a current activity of the user satisfy a trigger condition which has been previously defined by the user. If so, the computing device selects content from a content database, based on the context, to present to the user, and presents the selected content. | 06-03-2010 |
20110302169 | IDENTIFYING ACTIVITIES USING A HYBRID USER-ACTIVITY MODEL - In a user-activity identification technique, a user's actions are monitored while the user is using a computer. While these user actions are associated with user activities, the user activities are initially unspecified, so the tracked user actions constitute unsupervised data. Then, the tracked user actions are aggregated into subsets (for example, using clustering analysis), and user-activity classifications for the subsets (such as activity labels) are provided by the user, so the subsets constitute supervised data. Subsequently, when additional user actions (which are associated with one or more initially unspecified current user activities) are tracked, they can be associated with one or more of the classified subsets. For example, information about the additional user actions can be mapped in real time (or near real time) to one or more of the subsets using a supervised learning technique. In this way, the one or more current user activities can be identified. | 12-08-2011 |
20140100952 | METHOD AND APPARATUS FOR OPTIMIZING MESSAGE DELIVERY IN RECOMMENDER SYSTEMS - One embodiment of the present invention provides a system for optimizing the performance of a recommendation engine by generating an optimal recommendation time window. During operation, the system receives user click-through behavior on past recommendations and current user information, such as demographics and location. The system also receives information on one or more offers. The system determines the appropriate user-group for each user, and appropriate offer-group for each offer. The system then generates an optimal time period for a given recommendation for a given user and offer, wherein the optimal recommendation time window is the period when the offer is most likely to be accepted. | 04-10-2014 |
20140200960 | SYSTEM AND METHODS FOR OPTIMIZING RECRUITMENT - One embodiment of the present invention provides a system for recruiting individuals with a desired socio-demographic distribution. During operation, the system receives the desired socio-demographic distribution, obtains a seed sample comprising a plurality of participants, calculates a socio-demographic distribution associated with the seed sample, calculates an incentive provided to a user for recruiting an individual with a desired socio-demographic attribute, and presents the incentive to the user, thereby motivating the user to recruit the individual with the desired socio-demographic attribute. | 07-17-2014 |
20140344709 | RULE-BASED MESSAGING AND DIALOG ENGINE - One embodiment of the present invention provides a system for generating a message. During operation, the system receives user interaction event data. The user interaction event data describes explicit or implicit interactions of a user with a web application and/or mobile application. Next, the system modifies a graph describing the user's current context associated with the user based on an analysis of the user interaction event data, as interpreted by the system learning from previous processing of user interaction event data. The context graph includes information about the user's state, behavior, and interests, and some or all portions of the context graph may be shared between users. The system determines a set of rules associated with a group of users that includes the user, and then applies the determined set of rules to any context graph associated with the user to generate the message. | 11-20-2014 |
