A machine translation system from Arabic sign language to Arabic

摘要

Arabic sign language (ArSL) is one of the sign languages that is used in Arab countries. This language has structure and grammar that differ from spoken Arabic. Available ArSL recognition systems perform direct mapping between the recognized sign in the ArSL sentence and its corresponding Arabic word. This results in persevering the structure and grammar of the ArSL sentence. ArSL translation involves converting the recognized ArSL sentence into Arabic sentence that meets the structure and grammar of Arabic. We propose in this work a rule-based machine translation system between ArSL and Arabic. The proposed system performs morphological and syntactic analysis to translate the ArSL sentence lexically and syntactically into Arabic. To evaluate this work, we perform manual and automatic evaluation using a corpus on the health domain. The obtained results show that our translation system provides an accurate translation for more than 80% of the translated sentences.
