Linguistic characterization of sign language expressions for an automatic conversion from natural language sentences

자연언어 문장의 자동 변환을 위한 수화 표현의 언어학적 특성 분석

The linguistic characteristics of a sign language provide an important clue for an automatic construction of its expression from a given natural language sentence. For such characterization, we focus on the identification of elided constituents, the mapping of property-changing information into spatio-temporal dimension, and the need for rearranging the order of component information for enhanced quality of delivery. We use our characterization to implement a system that converts sentences in Korean into corresponding expressions in the Korean Sign Language.
