Semantic Enrichment…
• Text analysis tools that identifies pertinent
information
• Combs through documents and extracts
concepts
• To enrich the documents we use ‘skill
cartridges’ which contain taxonomies and
specific business rules.

Example taxonomy

« disabled students »
« disabled students »

Integration
Web services and connectors have been developed to facilitate the
integration of the taxonomy and semantic tools with the different OECD
applications
Luxid (Temis) and Sharepoint 2010 integration tested and the principle
validated
Luxid (Temis) and OpenText Content Server (OECD.Records)
integration tested and in production
