This paper explores the use of Proposi- tional Dynamic Logic (PDL) as a suit- able formal framework for describing Sign Language (SL), the language of deaf people, in the context of natu- ral language processing. SLs are vi- sual, complete, standalone languages which are just as expressive as oral lan- guages. Signs in SL usually correspond to sequences of highly specific body postures interleaved with movements, which make reference to real world ob- jects, characters or situations. Here we propose a formal representation of SL signs, that will help us with the analysis of automatically-collected hand track- ing data from French Sign Language (FSL) video corpora. We further show how such a representation could help us with the design of computer aided SL verification tools, which in turn ...
