Information technology for Ukrainian Sign Language translation based on ontologies

Lozynska O., Davydov M.

ECONTECHMOD : An International Quarterly Journal on Economics of Technology and Modelling Processes

2015

Vol. 4, No 2

13--18

The article discusses an information technology for Ukrainian Sign Language translation based on ontologies. The components of the technology that are based on grammatically augmented ontology are described. New methods and tools for Ukrainian Sign Language translation were developed. These tools can be used for the development of a machine translation system from spoken to sign language and vice versa to facilitate communication between deaf people and those who do not speak sign language. The experiments for Ukrainian Sign Language translation were conducted. The increase of the percentage of correctly parsed sentences shows the feasibility of using the information technology for Ukrainian Sign Language translation.

Spoken and sign language processing using grammatically augmented ontology

Davydov M., Lozynska O.

Applied Computer Science

2015

Vol. 11, no 2

29--42

The mathematical model of grammatically augmented ontology was introduced to address this issue. This model was used for grammatical analysis of Ukrainian sentences. Domain specific language named GAODL for description of grammatically augmented ontology was developed. The grammar of the language was defined by means of Xtext extension for Eclipse. The developed language was used as an auxiliary part of the information technology for bidirectional Ukrainian sign language translation.
