Patent Images
1. An interactive method for finding items in a database, said method comprising the steps of:
- generating a list of N items according to a procedure based upon a probability distribution over the items in the database;
displaying said list of N items to a user;
capturing a user response to the displayed items through an interactive user-interface, wherein said response expresses a relation between the displayed items and an item being searched for;
recomputing the probability distribution over items in the database according to the user response; and
repeating the above steps until the item being searched for is one of the N items displayed.

Abstract
A queryless, multimedia database search method incorporating a Bayesian inference engine that refines its answer with each user response. The set of user responses includes of a series of displays and user actions, and is defined by a relatively simple user interface.

21. An interactive method for measuring the effectiveness of a database search, said method comprising the steps of:
-
generating a target object for which to be searched; displaying said target object and a set of candidate objects to a user; measuring the search effectiveness by evaluating one or more metrics of difficulty user has in finding the target; and repeating the above steps while averaging the measures of difficulty.
