The Sign Language Dataset Compendium


POLYTROPON Parallel Corpus

The POLYTROPON Parallel Corpus is a corpus of Greek Sign Language and Greek. The corpus consists of 3600 sentences performed by a single signer in three repetitions each. The POLYTROPON corpus was constructed at the Athena Research Center at the Institute for Language and Speech Processing (ILSP) under the lead of Eleni Efthimiou.

Basis for the POLYTROPON Parallel Corpus is the POLYTROPON Lexicon. For each sign entry in the lexicon a GSL example of use was recorded and translated to Modern Greek. The annotation provides information for the grammar levels of lexicon, morphology, syntax and semantics.

Recordings were made with one HD and one kinect camera capturing the front view of the signer. The recording took place in a studio with uni-coloured background.
