1. A computer-implemented method for robust language processing, comprising the steps of:

  • accepting language in text form;

    segmenting the text language into one or more individual instructions, said segmenting being performed in accordance with predefined sets of rules and specific words that indicate at least the beginning or end of an instruction;

    parsing the one or more individual instructions; and

    skipping one or more words in an instruction if a parse cannot be accomplished by said parsing step in a predetermined time or without a parsing failure;

    wherein said parsing step and said skipping step together comprise the steps of;

    first determining whether parsing is presently at any of at least one predetermined keyword;

    if the portion of the instruction being parsed is not at any of the at least one predetermined keyword, then moving parsing ahead one word and repeating said first determining step;

    if the portion of the instruction being parsed is at any of the at least one predetermined keyword, then parsing the instruction and second determining whether the end of the input has been reached; and

    if the end of the input has not been reached, then repeating said first determining step.
