Abstract:
1. A method performed by at least one electronic device having a processor and a memory for generating a term-association vector space comprising a set of term vectors and at least one document vector, said method comprising: receiving a plurality of documents in electronic form; extracting terms from said plurality of documents; saving each of said terms in said memory; forming a first set of enumerations by enumerating term connections between each pair of said terms in said plurality of documents; saving said first set of enumerations in a first matrix in which the terms represent both the rows and columns, and in which each cell contains a number representing the enumeration, from the first set of enumerations, of connections within the plurality of documents between the term represented by its row, and the term represented by its column; saving the rows of said first matrix as a collection of term vectors defining a vector space; forming a second set of enumerations by enumerating, for each pair of said terms in said plurality of documents, the term connections between said each pair of terms within a single document of the plurality of documents; saving said second set of enumerations in a second matrix having the same number of rows and columns as the first matrix, and in which each cell contains a number representing the enumeration, from the second set of enumerations of connections within the single document between the term represented by its row, and the term represented by its column; and adding the rows of said second matrix together to produce a document vector representing the single document within said vector space.
