Abstract: Instead of using a central site including spidering software to recursively search all linked web pages and generate a search index of the Internet, index cards files are created and stored on each web site to provide meta data in the form of conceptual or non-keyword information about the site, such as demographics and categorization information. The meta data is periodically collected and aggregated on a central server. A central catalog of object references is compiled on the central site from the meta data reported from each web site. The information from the index cards is utilized in constructing the central catalog so that more accurate search results may be generated for search queries applied to the catalog, so that the search results may be ranked in meaningful ways, and so that web sites may be more accurately rated.

Abstract: A data driven discrete parallel processing computing system for searches with a key-ordered list of data objects distributed over a plurality of servers. The invention is a data-driven architecture for distributed segmented databases consisting of lists of objects. The database is divided into segments based on content and distributed over a multiplicity of servers. Updates and queries are data driven and determine the segment and server to which they must be directed avoiding broadcasting. This is effective for systems such as search engines. Each object in the list of data objects must have a key on which the objects can be sorted relative to each other. Each segment is self-contained and doesn't rely on a schema. Multiple simultaneous queries and simultaneous updates and queries on different segments on different servers result in parallel processing on the database taken as a whole.
