Intro and background
• Ecoterm grew out of the Ecoinformatics
International Cooperative Initiative
http://ecoinfo.eionet.europa.eu
• In 2003, Technical Working Group
realised the need to share terminology
and meaning in support of data sharing
• Realised that this needed to be an
international effort
Charter Statement of Mission
•
•
•
Make environmental terminologies more
interoperable and generally useful
Standards regarding terminology will provide
the integration of meaning and definitions
across heterogeneous data and information
systems allowing users of the data to
understand the similarities and differences
among terms and data.

Ecoinformatics Web site –

I – Geneva, April 2004
II – Berlin, April 2005
III – Rome, May 2006
IV – Vienna, Spring 2007 (planned)
20-30 participants from a variety of
environmental terminology organizations
Participants include terminology developers,
IT professionals, and those interested in
multilingual issues from governments,
intergovernmental organizations (especially
UN agencies), scientific institutions,
corporations and vendors
Technical Activities
• Collecting information about
environmental terminology resources
• Taxonomy of knowledge organization
systems (KOS) and definitions of
relationship types
• Reviewing relevant terminology
standards
• Investigating technologies for
interoperability such as SKOS (Simple
Knowledge Organization Systems)
Technical Activities, contd.
• Intersections with the 11179
enhancements, in particular the XMDR
Project
• Develop use cases, including
scenarios, needed KOSs and
audience(s)
• Terminology web services and the
Semantic Web
Web Services Prototype
• US National Agricultural Library
developed a prototype terminology
web service
• Search in NAL’s Agricultural Thesaurus
(NALT), select a term, transfer it to
GEMET and search using terms in
other languages
• USGS/BIO used SKOS and web
services with GEMET and the
Biocomplexity Thesaurus
Current issues:
Ecoterm III Meeting Topics
•
•
•
•
•
Developing and Maintaining KOS Content
Delivering and Visualizing the KOS
KOS Interoperability
Update on Standards
•
•
SKOS (Simple Knowledge Organization Systems)
Terminology Mark-up Framework
•
•
Environment as a Community of Interest
Discussion of Common Semantic Relations
Working Session
Ecoterm III Outcomes
•
•
•
•
Develop metadata for KOS (FAO and USGS)
Develop a registry of environmental KOSs
with metadata (FAO, USGS, UNEP)
Implement and populate a registry of current
terminology web services (USGS)
Extend the development of SKOS-based
interoperable KOSs by adding additional
systems and integrated search and display
(EEA, USGS and FAO)
Applied knowledge management
technologies in EEA services
(with Antonio de Marinis)
Stefan Jensen, EEA, Copenhagen
Starting points
• Developing GEMET thesaurus since 1996
(ca. 5300 terms in 21 languages, polyhierarchy,
Definitions in 5 languages)
> Indexing metadata (catalogues) for
harmonisation and search purposes
> translation support
• Developing EEA Glossary since 1998
(ca. 1100 terms in EEA languages, EEA website
oriented)
> Indexing EEA websites for navigation purposes
Nowadays challenges
• More in-depth (semantic) linkages of websites
using multiple (multilingual) terminology
resources
• Multiple approaches in maintaining and providing
semantic tools
ALiSS definition and goal
ALiSS is a software agent - more precisly an adaptive
web agent - which makes use of specific ontologies in
order to semantically organise, adapt and relate
information on the web - making one step towards the
Semantic Web.
Goal:
•
The goal is to assist the user in navigating the web. The
user will find the right information at the right time and
context.
•
The webmaster will not have to manually create and
maintain a large number of links and related
information.
ALiSS will take care of this!
