Extended User Documentation for the LT4eL Project

LT4eL is a project that offers a set of language technology based services for e-Learning platforms. The acronym stands for Language Technology for e-Learning. Basic services are keyword generation, definition detection and enhanced semantic and multilingual search capabilities. The tools support a more effective metadata annotation of learning objects, authoring of glossaries and better search functionalities in learning management systems.

This document is part two of the deliverable 4.1 as described in the technical annex of the project. This document is an extension to the documentation of the ILIAS learning management system. It addresses all functionalities that have been changed, extended or added due to the developments of the LT4eL project:

  • Learning Object Management / Authoring: Extension of metadata management by adding semi-automatic keyword generation. The related documentation is part of the documentation module "Online Assistance for ILIAS Authors".

  • Glossary Generation: Semi-automatic extraction of glossary terms and definitions from existing learning objects to facilitate the generation of glossaries. The related documentation is part of the documentation module "Online Assistance for ILIAS Authors".

  • Extended Search Engine: The search engine makes use of additional ontology-based and metadata-based (keywords) information. Four different search modes can be combined to search for learning matierial. The related documentation can be found here.

  • Ontology Browsing: The ontology browser allows users to explore the ontology in two presentation modes, hierarchical and alphabetical. They can search for learning objects related to selected topics in multiple languages. The related documentation can be found here.

  • Personal Desktop: Users can create references to learning objects on their personal desktop on the basis of search results. They can rearrange learning objects according to their individual needs. The related documentation can be found here.

All source code of the project is available at https://sourceforge.net/projects/lt4el.
