  1. WP 4: Integration of Language Technology Tools into ILIAS Learning Management System Alexander Killing Review Meeting, Zürich, 25 January 2008

  2. WP4 Tasks and Goals • Integration of LT4eL Tools developed by WP2 and WP3 into ILIAS LMS prototype. (D 4.1) • Develope and provide documentation for a standard-technology-based interface between the LT4eL Tools and any LMS. (D 4.1) • Goal: Simple-as-possible, well-documented and portable interface to foster re-use of the tools in other learning management systems.

  3. Integration Timeline M21: First Version of Deliverables M24: Second Version of Deliverables Bugfix Branch for M24 Version M30: Last Version of Deliverables Main Branch: New Development for M30 Version Dec 2006 May 2007 Sep 2007 Dec 2007 May 2008 Integration 1st Cycle Integration 2nd Cycle Testing & Bugfixing & Improvements Testing & Fixing Validation 1st CyclePre-Trials Validation2nd Cycle Validation3rd Cycle

  4. Issues / Bug Tracking • Bug Tracker is publicly accessible at Sourceforge.net • More than 150 reports (120 solved) • Major Improvements have been made concerning: • General Stability / Performance, especially of Semantic Search (Concurrent Users) • Usability of Glossary Candidate Detector in ILIAS (Navigation from LOs to glossaries) • Problems with specific Learning Objects (Annotation) • Translations of User Interface in Partner Languages

  5. Setup Language Technology Server(Tomcat Based) Learning ManagementSystem Use functionalitiesthroughSOAP ILIAS (Prototype) Application Logic Webservices SOAP LOs SOAP Key WordExtractor • Use Case Scenarios • Upload Learning Object (LO) • Find Keyword Candidates for LO • Find Definitions for LO • Search for LO(Ontology Support) • Browse Ontology Uses System GlossaryCand. Detector LanguageModel OntologyManager OntologyLexicons SemanticSearch Third PartyTools

  6. General Web Service Operations • sendNewLO() • Send a new learning object (from lms) to the language technology server. • getStatus() • Get current input processing status of a learning object. • deleteLO() • Delete a learning object on the language technology server.

  7. KWE/GCD Web Service Operations • findKeywordCandidates() • Generate list of keywords for a learning object. • sendApprovedKeywords() • Send user approved keywords back to language server. • findDefinitionCandidates() • Generate list of definitions for a learning object.

  8. Search and Ontology Web Service Operations • search() • Ontology extended (multilingual) learning object search. • getConceptNeighbourhood() • Get concepts and relations of a given concept (e.g. enables ontology browsing).
