The Information System PYLES is a management system for on-line lessons, designed to support accesible asynchronous e-learning, addressing learning needs of students with various communication capabilities and needs at the Technological Educational Institute of Athens (TEI-A). It, thus, exploits both uptodate assistive technology software and content in various forms. This platform has been used as the basis for the development of an active repository of multimodal educational resources, also incorporating a terminology lexicon for the Greek Sign Language (GSL) and a general purpose dictionary of GSL. The platform provides advanced customization options according to user needs but also a collaborative environment for the support of teaching and learning processes. The information system ( ) is built on the open code platform ‘Open eClass’ (, a free e-learning platform that it actually enriches with tools and functionalities which allow extended accessibility regarding both the environment and the educational content. Regarding customization to serve GSL signers’ needs, the platform incorporates: - Selected lesson presentations in GSL on the basis of deaf students’ preferences regarding the curriculum offers - An on line dictionary of general purpose lemma list - An on line terminology glossary - Administrative form related information in GSL Following the Open eClass patern, three basic user roles are supported: (i) student, (ii) instructor, and (iii) administrator. However, the platform also supports special intermediary roles such as “administrator assistant”, “user administrator”, “group leader” and “visitor”. These roles serve among other functionalities, the options available for lexical material enrichment through crowd sourcing. The GSL terminology environment allows for the creation of different glossaries directly by their users, where GSL signers are invited to upload their suggestions for various terms under specific quality control conditions. Authorized users may enter new terminology items including the term definition and various supporting multimedia material (icons, video, text etc), while they can modify or completely delete entries. Furthermore, they can validate terms suggested by non authorized users to make them visible to the whole user community. Terminology enrichment actions incorporate: 1. New lemma or new sense entry 2. Modification of a lemma or a sense3. Validation of a proposed lemma sense 4. Communication or hiding of a lemma sense or a lemma description 5. Linking of a lemma with a lemma in a different language (Greek and/or English)
