Analysis of finger movements description sentences in sign language dictionary

摘要

This paper reports the analysis of finger movements description in sign language dictionary and its consequent application. By using IBUKI system which is our natural language analysis system, we analyzed those sentences morphologically and then syntactically. We could transform them into a standard form with 6 (or 11) arguments. On the bases of this standard form, we could define singleton of movement by which a whole movement can be constructed with their time sequential combination, simultaneous combination or modifying combination. Next we define a similarity distance between movements. With these we built an electronic sign language dictionary which enables a search with pieces of movements and can shows similar sign words in view point of movements.
