  • METHODS OF EVALUATING SEMANTIC DIFFERENCES, METHODS OF IDENTIFYING RELATED SETS OF ITEMS IN SEMANTIC SPACES, AND SYSTEMS AND COMPUTER PROGRAM PRODUCTS FOR IMPLEMENTING THE SAME
    Publication number: 20160012123
    Abstract: One aspect of the invention provides a method of evaluating semantic differences between a first item in a first semantic space and a second item in a second semantic space. Thee method includes: calculating a first ordered list of N nearest neighbors of the first item within the first semantic space; calculating a second ordered list of N nearest neighbors of the second item within the second semantic space; and computing a plurality of similarity measures between the first n nearest neighbors of the first item and the first n nearest neighbors of the second item, wherein n and N are positive integers and 1?n?N.
    Type: Application

  • METHODS AND COMPUTER-PROGRAM PRODUCTS FOR TEACHING A TOPIC TO A USER
    Publication number: 20130029308
    Abstract: Aspects of the invention provide methods and computer-program products for teaching a topic to a user. One aspect of the invention provides a method for teaching a topic to a user. The method includes: administering one or more question to assess the user's knowledge of the topic; displaying a first interactive pedagogical agent and a second interactive pedagogical agent; and facilitating a trialog between the user, the first interactive pedagogical agent, and the second interactive pedagogical agent.
