Abstract:
1. A method for enabling the purchase of an item based on topically indexing an Internet-based document collection that is initially unconnected with a body of textual reference material, comprising: processing said body of textual reference material to derive keywords for each topic of a plurality of topics, assigning a weight to each keyword in a text portion of the body of textual reference material; associating a keyword with a corresponding text portion if the weight of said keyword in said corresponding text portion is equal to or greater than a weight of said keyword in the text portions other than the corresponding text portion, or is equal to or greater than a predetermined threshold value; forming first keyword-weight pairs of said associated keywords; applying the associated keywords to at least one Internet-based document from said initially unconnected Internet-based document collection and forming second keyword-weight pairs associated with said at least one Internet-based document; forming a numeric score between the first and second keyword-weight pairs; based on said score, associating said at least one Internet-based document from said initially unconnected Internet-based document collection and said single topic from said plurality of topics; and enabling a purchase of an item in an on-line transaction based, in part, on the at least one associated Internet-based document.
