1. A computer-readable medium containing program instructions for deducing meaning from a natural language input, said program instructions performing steps comprising:

  • (a) receiving an ordered string of separate word objects of a selected language, where each of said word objects includes at least one alphanumeric character and is delimited from an adjacent word object, said ordered string having a length equal to the number of said word objects and having a natural language meaning;

    (b) selecting a word window length that is initially at least two and that is no greater than said length of said ordered string;

    (c) successively moving said word window along said ordered string, and removing a substring of word objects that fall within said word window from said ordered string when said substring has a recognized meaning, until all substrings of said ordered string that fit within said window have been analyzed; and

    (d) adjusting said word window length and repeating step (c) until only an unrecognized residual of word objects of said ordered string remains.
