Text indexing for web enabled database applications is supported particularly well by open source RDBMS's. The TSearch functionality in Postgres provides stem-based searching out of the box, and is integral to many of the apps developed at Authentrics.
Authentrics staff have 12 patents pending related to their work for GraphWise, LLC to develop a tabular data search engine. Our research in this area is now focused on enterprise applications of these techniques, rather than the broader internet arena.
Another patent pending by Authentrics staff involves the correlation of graphs allowing users to search based on the shape and axis information of a selected graph.
While not our specialty, Authentrics is versed in the techniques needed to place sites higher in search engine results. There is a lot of misinformation in this area, and Authentrics is able to separate the wheat from the chaff to sift out the effective actions that need to be taken to raise a site's probability of being near the top of search engine results hits.
