Topological and featureful annotation of SignWriting
Some examples

Corpus

The VisSE Corpus is a publicly available collection of instances of Spanish SignWriting.

  • 982 logograms (transcriptions of signs)
  • 6060 graphemes (each of the symbols: hands, faces, movements…)
  • Manually annotated

Quevedo

Quevedo is an open source library and application for annotating and automatically processing corpora of graphical languages.

VISSE APP

The representation encoded in the annotation, and the data we have collected in the corpus, allows us to build an automatic recognition of SignWriting pipeline using deep learning.

This recognition is used in a web application that explains (in Spanish) the meaning of SignWriting transcriptions.
