  1. LT4eL - WP1: Setting the sceneWP leader: UAICUniv. AI. I. Cuza of IasiFaculty of Computer Science Dan Cristea, Corina Forăscu, Dan Tufiş, Ionuţ Pistol, Diana Trandabăţ, Adrian Iftene Contact: dcristea@info.uaic.ro Utrecht Review Meeting, February 1, 2007

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

  3. Partners in WP1 • Utrecht University (UU), The Netherlands • University of Hamburg (UHH), Germany • University of Lisbon (FFCUL), Portugal • Charles University Prague (CUP), Czech Republic • Institute for Parallel Processing, Bulgarian Academy of Sciences (IPP-BAS), Bulgaria • University of Tübingen (UTU), Germany • Institute of Computer Science, Polish Academy of Sciences (ICS-PAS), Poland • Zürich University of Applied Sciences Winterthur (ZHW), Switzerland • University of Malta (UOM), Malta

  5. 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: http://consilr.info.uaic.ro/uploads_lt4el • Username: guestLt4eL • Passwd: elearning Demo version on CD

  6. O1. Collection of language resources and tools (1) • Inventarization and classification of existing tools (http://consilr.info.uaic.ro/uploads_lt4el/tools/all.php?) relevant to: • the integration of language technology resources in eLearning (WP2) • the integration of semantic knowledge (WP3)

  7. O1. Collection of language resources and tools (2) • Inventarization and classification of existing language resources • corpora and frequencies lists:http://consilr.info.uaic.ro/uploads_lt4el/menu/all.php • lexica: http://www.let.uu.nl/lt4el/wiki/index.php/Lexica_Joint_Table

  8. O2. Collection of LOs: the portal Uploads, updates & real-time statistics at http://consilr.info.uaic.ro/uploads_lt4el/ Criteria (→ attributes): • Subdomains relevant for beginners in IST & e-learning → Domain • Multilingualism → Language • Medium sized documents → Numberofwords • IPR~clear → IPR • Uniformity in topics →keywordsselected initially

  9. Collection of LOs: domains 1. Use of computers in education, with sub-domains: 1.1 Teaching academic skills, with sub-domains: 1.1.1 Academic skills 1.1.2 Relevant computer skills for the above tasks (MS Word, Excel, Power Point, LaTex, Web pages, XML) 1.1.3 Basic skills (use of computer for beginners) (chats, e-mail, Intenet) 1.2 e-Learning, e-Marketing 1.3 The I*Teach document (Leonardo project, http://i-teach.fmi.uni-sofia.bg/) 1.4 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, http://www.calimera.org/ )

  10. Collection of LOs: domains coverage

  11. The hierarchy of LOs’ formats

  12. Collection of LOs: annotation layers • Initial documents: doc, pdf, html, txt → Base-XML • Linguistic annotation: tokens, POS, lemma, chunks → WP2 XML format (LT4ELAna.dtd) • Keywords, definitions and ontology links annotations

  13. Level 1 conversions doc pdf latex other doc → html html plain text Base-XML

  14. Level 1 conversions doc → html (UTF-8) • MS Office: Save As html • OpenOffice Writer SXC/ODT: Save As html

  15. Level 1 conversions doc pdf latex other pdf → html html plain text Base-XML

  16. Level 1 conversions: pdf → html (UTF-8) 1. Adobe on-line conversion tool 2. pdfbox (Windows) 3. pdftohtml (Linux) 4. OpenOffice 5. Adobe Acrobat Professional

  17. Level 1 conversions doc pdf latex other html plain text Base-XML convertor Base-XML

  18. Level 1 conversions: html → Base-XML • The UAIC Java converter • keeps all the tags possibly useful (fixed) • produces a log of all the removed tags/data • The CUP html2xml.pl converter • tags kept according to a DTD

  19. Collection of LOs: second level morpho tok pos lemma NP Language specific tools tok-pos-lemma WP2 XML format

  20. Collection of LOs: second level morpho tok pos lemma NP tok-pos-lemma scripts WP2 XML format

  21. Collection of LOs: KW extractor WP2 XML format Level 2 KW extractor Level 3 Man KD XML Auto KD XML

  22. Collection of LOs: KW extractor WP2 XML format Level 2 Level 3 Man KD XML Auto KD XML KW extractor evaluation

  23. Collection of LOs: third level Man KD XML Auto KD XML def extractor Incl. km.xml, dm.xml Incl. akw, adef akw: automatically annotated kws adef: automatically annotated defs kmxml: manually annotated kws dmxml: manually annotated defs

  24. Collection of LOs: third level Man KD XML Auto KD XML def extractor Incl. km.xml, dm.xml Incl. akw, adef akw: automatically annotated kws adef: automatically annotated defs kmxml: manually annotated kws dmxml: manually annotated defs def extractor evaluation

  25. Open issues • Convertors • Tables, figures, page look… • IPRs • Clarify the IPR status • authors & EU + national legislation • Define IPR categories for LOs: • usage (free, restricted, for research...)

  26. WP1 over time Official end of WP1 Beginning of project D1.1 Evaluation December 05 May 06 Now February 06 • Structure & functionalities to the portal • BaseXML convertors • new LOs Initial collection on Portal • Levels 2&3 additions • new tools • grammars • guides, docs • - ontology, TermLex

  27. tok akw txt axml doc pdf latex html other tpl morpho adef pos lemma NP wp2xml sxml Level 1 Level 2 Level 3 Proposal: the hierarchy seen as a processing environment

  28. Conclusions • LOs, resources and tools collected • Initially: portal seen as a repository • Now: portal potentially integrated with the LMS as a processing environment
