Sign Language TranslationSystem ( TeST ) - Morpheme Converting Rules for Korean PredicatesSeok

There are two kinds of sign languages used in Korea. One is Korean Sign Language , which has the identical rules with that of Korean grammar, the other is Korean Natural Sign Language(KnSL), which is actually used by deaf person. KnSL diiers from Korean Language in morpheme characteristics. Therefore, morpheme translation rules must be de-ned rst for translation between these two. So, in this paper, we deene and implement morpheme translation rules for our TeST system (Korean Text-to-Sign Language Translation system). We successfully translated about 98KnSL with the rules proposed in this paper, and we also found the fact that special translation rules are necessary in many postpo-sitions and endings. Therefore, we propose some translation rules which are adopted to Korean conjugation and we also propose KnSL morpheme creation network by using morpheme translation rules.
