Abstract

Large stores of information are often organized in a hierarchical taxonomy to aid a search and retrieval of the information. The hierarchical taxonomy generally consists of related categories of information, called “nodes,” that each may contain information relevant to the search. Each node is addressable according to its path in the hierarchical taxonomy. In information stores where the number of nodes having relevant information is extremely large, such as the Internet, providing a cohesive, intelligent, and organized display of the search results becomes extremely important to the success of a user traversing the store to find relevant information. The invention provides such search results by ranking each node of the taxonomy to determine which nodes are most likely to be relevant to the search request. The invention then creates a conceptually-related “cluster” of nodes by selecting a relevant “seed” node and relevant nodes related to the “seed” node.
