Abstract:
1. A method for conducting information retrieval in a distributed network of nodes, the method comprising: receiving, by a computing device, a current message; differentiating, by the computing device, the current message between a query message and a reply message, and if the current message is a reply message, associating, by the computing device, said reply message with a node address originating said reply message and storing data representative of said associating, said data including the node address originating the reply message and a topic of a query that resulted in the reply message; when said current message is a query, determining, by the computing device, a similarity factor from data representative of the current message to data representative of the prior received queries and ranking each known node with respect to the current message based on said similarity factor; forwarding, by the computing device, said current message to only nodes of the distributed network having a predetermined statistical probability of having a reply relevant to said query based on the similarity factor; and receiving, by the computing device, a reply from at least one of the nodes of the distributed network having a predetermined statistical probability of having a reply relevant to said query based on the similarity factor.
