Integrating MultiWordNet with Italian Sign Language lexical resources
No full textA novel Italian Sign Language MultiWordNet (LMWN), which integrates the MultiWordNet (MWN) lexical database with the Italian Sign Language (LIS), is presented in this paper. The approach relies on LIS lexical resources which support and help to search for Italian lemmas in the database and display corresponding LIS signs. The lexical frequency analysis of the lexicon and some newly created signs approved by expert LIS signers are also discussed. The larger MWN database helps to enrich the variety and comprehensiveness of the lexicon. We also describe the approach which links the Italian lemmas and LIS signs to extract and display bilingual information from the collected lexicon and the semantic relationships of LIS Signs with MWN. The users can view the meanings of almost one fourth of the lemmas of MWN in LI
Language Resources for Computer Assisted Translation from Italian to Italian Sign Language of Deaf People
No full textA Virtual Character based Italian Sign Language Dictionary
No full textThis paper presents a novel Italian to Italian Sign Language Dictionary that displays word translation by means of a virtual character. The Dictionary is linked to MultiWordNet, a lexical and semantic database which includes several languages. The objective is to use it as a learning tool for Deaf people to enhance the learning of written language
A Multilanguage Database for Supporting Sign Language Translation and Synthesis
No full textThe design of a language database is an important task within projects targeting sign language research. In this paper is presented a database structure that supports both linguistic information and visualisation oriented data to assist a final publication of services for deaf people. The database has been designed within the Automatic Translation into sign LAnguageS (ATLAS) project that takes aim at getting the automatic translation from written Italian to Italian Sign Language (LIS). The final step of the overall process is the enrichment of the original video with a superimposed virtual character realised by 3D animated computer graphics. The top element within the database is the A_Product defined as the main primitive element managed by the ATLAS platform under which all the other data, from input sources to the final publication modalities and attributes lay. The A_Product includes the reference to the original content and all the intermediate elaborations results towards the final publication comprehensive of the virtual character animations. Among the others, the most important transformation is the automatic translation from a written Italian text to the intermediate
language AEWLIS (ATLAS Extended Written LIS), formalized within the ATLAS project
A Systematic Approach for Evaluating Satellite Communications Systems
Get PDFThe aerospace environment imposes straight opera- tive conditions so every electronic system usually needs to be validated for these. The same way, communica- tion systems need to be evaluated before their intro- duction in aerospace applications. In the paper we present a new methodology for the evaluation of com- munication systems in space applications. The meth- odology aims, by abstraction, at identifying all the critical aspects for the evaluation and at defining a standard and reusable framework in order to be appli- cable to any Communication Systems. The methodol- ogy has been applied for the evaluation of three Data Bus for satellite communications: 1553, 1-Wire and Profibus DP RS 485 based systems have been analyzed and evaluate
A Web Based Platform for Sign Language Corpus Creation
No full textThis paper presents the design and implementation issues of a tool for the annotation of sign language based on speech recognition. It is at his first version of stable development and it was designed within the Automatic Translation into Sign Languages (ATLAS) project. The tool can be used to gather data from the language for corpus creation and stores information in a Multilanguage Multimedia Archive. The objective is to create a corpus of Italian Sign Language for supporting an automatic translation system that visualizes signs by means of a virtual character. The tool allows the user to search for media content related to signs and stores metadata about the translation and annotation processe
