1. A computer-implemented method for constructing a single vector representing a semantic abstract in a topological vector space for a semantic content of a document on a computer system, the method comprising:

  • storing a semantic content for the document in computer memory accessible by the computer system;

    identifying a directed set of concepts as a dictionary, the directed set including a maximal element at least one concept, and at least one chain from the maximal element to every concept;

    selecting a subset of the chains to form a basis for the dictionary;

    identifying lexemes/lexeme phrases in the semantic content;

    measuring how concretely each lexemes/lexeme phrase is represented in each chain in the basis and the dictionary;

    constructing state vectors in the topological vector space for the semantic content using the measures of how concretely each lexemes/lexeme phrase is represented in each chain in the dictionary and the basis;

    superpositioning the state vectors to construct the single vector; and

    comparing the single vector with a second semantic abstract for a second document to determined whether the second document is semantically close to the document.
