Claim Text:
1. A system, comprising: a memory having computer readable computer instructions; and a processor for executing the computer readable instructions to perform a method comprising: accessing a graph comprised of a plurality of nodes and edges, each node representing a topic, and each edge representing a known association between two topics; determining a first probability that, given that an agent has expressed an interest in a single topic represented by a node in the graph, the agent is interested in each of the topics represented by nodes in the graph, the determining comprising: deriving a second probability that, given that the agent has expressed an interest in two or more topics represented by nodes in the graph, the agent is interested in each of the topics represented by nodes in the graph, calculating an estimate probability by combining the first probability and the second probability using a log-likelihood ratios, wherein lack of interest expressed by the agent in each of the topics is represented as subtraction using the log-likelihood ratios.
