Initially, a plurality of polysemic symbol sequences are input through a keyboard segmented into a plurality of semantic, syntactic, or pragmatic segments including agent, action and patient segments, for example. One polysemic symbol sequence, including a plurality of polysemic symbols, is input from each of the three segments of the keyboard. A symbol parsing device, in a symbol parsing layer, then parses each of the plurality of symbols in each polysemic symbol sequence to access a previously stored word, morpheme, or phrase. The word, morpheme, or phrase is accessed which corresponds to the polysemic symbol sequence and further corresponds to one of the designated agent, action or patient segments. Each accessed word, morpheme, or phrase further accesses corresponding and previously stored grammatical and semantic information. An intelligent word parsing layer then receives and subsequently applies each of the plurality of words, morphemes, or phrases to a predetermined hierarchy of rules based upon the grammatical and semantic information corresponding to each of the plurality of words, morphemes, or phrases. The intelligent word parsing device in the word parsing layer subsequently parses the received plurality of accessed words, morphemes, or phrases into a syntactically or pragmatically correct output sentence or other word message.Other References
