LT4eL - WP1: Setting the scene WP leader: UAIC Univ. AI. I. Cuza of Iasi Faculty of Computer Science Dan Cristea, Corina Forăscu, Dan Tufiş, Ionuţ Pistol, Diana Trandabăţ, Adrian Iftene Contact: Utrecht Review Meeting, February 1, 2007

Objectives 1.inventarization and classification of existing tools necessary for the development of the relevant functionalities (i.e. key word extractor, glossary candidate detector); 2.collection and normalization of the learning material related to the use of the computer in education (Humanities, Social Sciences); 3.investigation of IPR issues; 4.adoption of relevant standards for linguistic annotation of learning objects; 5.dissemination of the results through a Web portal

The Portal A working space: –Repository for resources, tools, deliverables –Exchange information among participants –Statistics Hosted by UAIC: –January 2007: 1.15 Gb (without realTimeStat, searchForm, upload/updateForm) Address: –Username: guestLt4eL –Passwd: elearning Demo version on CDCD

O1. Collection of language resources and tools (1) Inventarization and classification of existing tools ( relevant to: –the integration of language technology resources in eLearning (WP2) –the integration of semantic knowledge (WP3)

O1. Collection of language resources and tools (2) Inventarization and classification of existing language resources –corpora and frequencies lists: –lexica:

O2. Collection of LOs: the portal Uploads, updates & real-time statistics at Criteria (→ attributes): -Subdomains relevant for beginners in IST & e-learning → Domain -Multilingualism → Language -Medium sized documents → Number of words -IPR~clear → IPR -Uniformity in topics → keywords selected initially

Collection of LOs: domains 1. Use of computers in education, with sub-domains: 1.1 Teaching academic skills, with sub-domains: Academic skills Relevant computer skills for the above tasks (MS Word, Excel, Power Point, LaTex, Web pages, XML) Basic skills (use of computer for beginners) (chats, , Intenet) 1.2 e-Learning, e-Marketing 1.3 The I*Teach document (Leonardo project, Impact of use of computers in society 1.5 Studies about use of computers in schools / high schools 1.6 Impact of e-Learning on education 2. Calimera documents (parallel corpus developped in the Calimera FP5 project, )

Collection of LOs: domains coverage

The hierarchy of LOs’ formats
