1. A user-interactive computer-aided English text categorization method that supports the use of quantified conditions and implemented on a computer having a computer user interface for prompting and receiving user selections and inputs, said method comprising the steps of:

  • accepting input as English language text, formatting the text for subsequent processing, and assigning identifications (IDs) to sets of the input English language text;

    establishing the characteristics of a complete set of text as the basis for the quantifiable conditions, the characteristics including co-occurring terms, pair-wise syntactic similarity coefficients (SCs), combinations of parts of speech;

    constructing interactively with prompted operator input classification ectypes (CEs) as text-edited rules and tables to specify the quantified conditions for representation of a category within a classification structure, said CEs being of two forms, word form and integer form CEs, said word form CEs being based on a list of designated words from the input English language text, said integer form CEs being of two types, ID-based and SC-based, ID-based CEs supporting logical operations as a basis for categorizing statements and SC-based CEs using the pair-wise SCs between statements; and

    applying constructed CEs to prepare lists of candidates for each category.
