Transcript WP1: Integration of language resources in eLearning

WP 4: Integration of Language
Technology Tools into ILIAS
Learning Management System
Alexander Killing
Project review, Utrecht, 1 Feb 2007
WP4 Tasks and Goals
• Integration of LT4eL Tools for semi-automated
metadata generation, definitory context extraction and
ontology supported extended data retrieval into a
learning management system. (prototype based on
ILIAS LMS)
• Developing and providing documentation for a
standard-technology-based interface between the
language technology tools and a learning management
system.
• Goal: Simple-as-possible, well-documented and
standards-based interface to foster re-use of the tools
in other learning management systems.
WP4 Dependencies
• WP 1: Collection and preparation of learning
objects.
• WP 2: Delivers keyword and glossary
functionalities to be integrated.
• WP 3: Delivers search and ontology
functionalities to be integrated.
• WP 5: Evaluation and validation.
M12 Deliverables

Web Service Operations, Core
• sendNewLO()
– Send a new learning object (from lms) to the language
technology server.
• getStatus()
– Get current input processing status of a learning object.
• getDomains()
– Get all available domains.
• deleteLO()
– Delete a learning object on the language technology server.
Web Service Operations, KE/DF
• 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.
• sendApprovedDefinitions()
– Send user approved definitions back to language server.
Web Service Operations, OMS
• findOntologyAnnotation()
– Provides ontology fragments for annotation of a learning
object.
• sendApprovedOntologyAnnotation()
– Send user approved ontology annotation back to language
server.
• getConceptNeighbourhood()
– Get concepts and relations of a given concept (e.g. enables
ontology browsing).
• search()
– Ontology extended (multilingual) learning object search.
