About the Zerx patented search algorithms

    The USPTO has granted Zerx, LLC patent coverage for all of the following technologies invented by Zerx:

      Related sites - Zerx has patented the algorithms for determining website relationships through the use of link analysis (correlation of links). Additionally, our patented algorithms also analyze links to determine the strength of those relationships between websites.

      Search ranking using a relationship database - Zerx uses this relationship database to rank search results by scoring each result's relationship to the other search results. Sites having the strongest relationship to the other search results will get ranked higher. Sites which have no relationship to the search results will get ranked lowest.  This allows the search to use objective relevancy when ranking websites.

      Search refinement using a relationship database - Zerx allows refining search results based upon the relationship to a specific search result. This refinement can be: listing all related sites to a given web site; a cross section of results given by the intersection of search results and a web page relationship; or by a cross section of results given by the intersection of common sites related to two or more web pages.  This allows for custom category building based on relationships and keywords.

      Additionally, we use our patented algorithms to provide the following features:

      Concept searching - Zerx allows the user to perform a conceptual search of our database by including sites that don't contain the search terms, but are highly related to the search results.  This feature can perform two different effects: (1) Pulling in contrasting websites to the search query. (2) Pulling in strongly related sites to the search query which fail to meet the search criteria.

      Clustering results - Our patented databases allow Zerx to present clusters of relationships within the results.  This allows for viewing closely related areas of the web containing a search term.

      Reranking results based on relevant clusters - Zerx allows the user to select the relevancy of clusters in the results in order to rerank the results by ranking relationships to sites in user selected clusters higher.
