Towards Automatic Sign Language Annotation for the ELAN Tool

A new interface to the ELAN annotation software that can handle automatically generated annotations by a sign language recognition and translation framework is described. For evaluation and benchmarking of automatic sign language recognition, large corpora with rich annotation are needed. Such databases have generally only small vocabularies and are created for linguistic purposes, because the annotation process of sign language videos is time consuming and requires expert knowledge of bilingual speakers (signers). The proposed framework provides easy access to the output of an automatic sign language recognition and translation framework. Furthermore, new annotations and metadata information can be added and imported into the ELAN annotation software. Preliminary results show that the performance of a statistical machine translation improves using automatically generated annotations.
