Abstract: 
A method is provided for determining how semistructured information is organized in disparate semistructured resources by providing a wrapper to extract information and to provide structured information (e.g., tuples of an SQL database) to a mapper coupled to a standard relational database engine. In a specific embodiment, a querying agent is provided on top of the mapper. Further according to the invention, structured high-level user queries are processed across the disparate semistructured resources using a plurality of wrappers each dedicated to a particular resource.

Method for searching a queued and ranked constructed catalog of files stored on a network

Abstract: A method of constructing a catalog of files stored on a network comprised of a plurality of interconnected computers each having a plurality of files stored thereon. The method is accomplished by establishing a queue containing at least one address representative of a file stored on one of the interconnected computers, ranking each address in the queue according to the popularity of the file presented by the address, downloading the file corresponding to the address in the queue having the highest ranking, processing the downloaded file to generate certain information about the downloaded file for the catalog, adding to the queue any addresses found in the downloaded file, and determining the popularity of file represented by the addresses in the queue according to how often a file is referenced by a computer other than the computer on which the file is stored.
