last year of the project, and we reported them in the domestic and international symposiums.1. Collection of sign utterances : we videotaped the utterances of the two deaf and one CODA,2. Data description and development of description tool : we developed special tool for description of sign utterances which we submit a patent. Using the tool we described the signers' intuition through the discussion. We verified the hypothesized description method with them.3. Data analysis and dictionary : we proposed the sign utterance description system, sIGNDEX V.2 which follows the sign description system, sIGNDEX V.1.4. Expansion of the computer dictionary of sign language : we described the Non-manuals signals (NMS) of JSL which mark the syntactic phenomena and the dictionary contained sign sentence usages. It contributed to the sign database which works as a base for sign recognition and sign machine translation.
