Abstract
The invention is a method for textual searching of text-based databases including databases of compiled internet content, scientific literature, abstracts for books and articles, newspapers, journals, and the like. Specifically, the algorithm supports searches using full-text or webpage as query and keyword searches allowing multiple entries and an information-content based ranking system (Shannon Information score) that uses p-values to represent the likelihood that a hit is due to random matches. Additionally, users can specify the parameters that determine hits and their ranking with scoring based on phrase matches and sentence similarities.

36. A search engine for searching a digitized database and identifying and ranking relevant hits, the search engine comprising:
an algorithm for analyzing the database, wherein the algorithm compares a query with the database to identify a hit, and ranks the hit in comparison to other hits in the same database, wherein the hit is ranked by numerical value of a score, the score selected from the group consisting of a cumulative score of shared words between the query and the hit;
a cumulative score of shared phrases between the query and the hit;
a percent identity of Infotoms shared between the query and the hit, and a cumulative score of shared Infotoms.- View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64)
