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

  • Integration Plan(Part of WP2/WP3 reports)


M24 Deliverables

  • Prototype of ILIAS learning management system with integrated language technology tools

  • Webservice Interface Documentation

  • Integration Guidelines

Results of Integration Planning Meeting

  • 12 starting operations for web service interface

    • Derived from WP2 / WP3 Use Cases

  • User Interface Prototypes

  • Incremental Document Handling

    • Starting with LT4eL-Ana XML Documents

    • (X)HTML / Text Documents (Single File)

    • (X)HTML / Text Documents (Multiple Files)

    • Other formtats: PDF, SCORM, Word?, ...


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.
