Abstract

ChemgaPedia is a multimedia, webbased eLearning service platform that currently contains about 18.000 pages organized in 1.700 chapters covering the complete bachelor studies in chemistry and related topics of chemistry, pharmacy, and life sciences. The eLearning encyclopedia contains some 25.000 media objects and the eLearning platform provides services such as virtual and remote labs for experiments. With up to 350.000 users per month the platform is the most frequently used scientific educational service in the German spoken Internet. In this demo we show the benefit of mapping the static eLearning contents of ChemgaPedia to a Linked Data representation for Semantic Chemistry which allows for generating dynamic eLearning paths tailored to the semantic profiles of the users.

Highlights

Drug maker says data volume is doubling every 15 months and “we don’t know how to filter it”
Collection of 1.700 multimedia eLearning lessons in the subject of Chemistry and related sciences Some 18.000 interactive content pages with approx. 25.000 media elements 4 Million users during last 12 months, Homogenous target group students, teachers, trainers Localization: Currently German spoken areas Open platform concept without registration Teaching paths are coded with the content by the initial authors XMLbased Guided bulletin board www.chemgapedia.de
Align our ontology with ChEBI and PubChem schemata from Biio2RDF Enrich ChemgaPedia content with chemical identifiers and classifications Improved search functionality Enhance ChemgaPedia content with related contentfrom DBPedia (Germany) Based on the Open Semantic Framework Core part is StructWSF The GUI is implemented with DRUPAL (Open Source CMS) and the con Struct component Faceted Search functionality
