Environmental Terminology Environmental Terminology System and Services (ETSS)System and Services (ETSS)
June 2007
EPA’s System of RegistriesEPA’s System of Registries
• A series of registries that help manage key business objects
• Most are authority files:– Chemicals and substances– Facilities– XML Schema/Tags
• Newly added Environmental Terminology System and Services (ETSS) will address topical terminology
Why Terminology? Why Terminology?
• So that we know what we mean
– Key business terms and acronyms
• So we can find stuff
– Indexing, cataloging, keyword management
• Others are counting on us
– Emergency response
– Other Federal Gov’t
– International efforts Gary Larson – The Far Side
EPA’s History of TerminologyEPA’s History of Terminology
• EPA Terminology Reference System (www.epa.gov/trs)– Searchable repository– Over 250 distinct vocabularies; over 11,000 terms
• Environmental regulations and laws• EPA Program glossaries and term lists• GEneral Multilingual Environmental Thesaurus (GEMET)
– Significant limitations• Limited search capability• Lacks web services• Lacks editing functionality• Doesn’t support multilingual capability• Insufficient for concept management
What Is the ETSS?What Is the ETSS?• Search & Discovery Portal – a tool to find, use,
and download terminology• Terminology Management – a repository of
important terms with user interfaces for creation, storage, maintenance, harmonization, and distribution of various types of terminology
• Automated Services – Web interfaces and services to allow exchanges of terminologies with Agency and partner systems
• Collaborative Stewardship – a framework for the development of vocabulary-specific workflows and processes
Key ETSS CustomersKey ETSS Customers• Human Customers
– EPA vocabulary developers like the Web Taxonomy Project– Policy makers defining terms in regulations– System developers selecting XML tags and defining data
elements– Program managers and researchers seeking to develop and
use terms and glossaries– Non-EPA vocabulary developers interested in environmental
terms– Anyone needing to understand environmental terminology– Stakeholders, partners and the public
• System Customers– Search engines – to expand searches or provide the basis for
taxonomies or folders– Enterprise content management – source of value domains
and controlled vocabularies– Other systems that use pick lists or taxonomies

Current StatusCurrent StatusWhere We’re At• Dow Jones’ Synaptica KMS software selected• Editorial system in production• Over 250 vocabularies and 11,000 terms migrated• New Web Taxonomy created and maintained• Supporting development of EPA Quality Glossary • Training sessions held for editors Next Steps• Develop public end-user interface• Establish governance and workflow• Integrate with SOR and other systems• Develop strategy for moving toward a concept-based system

What is Concept Management?What is Concept Management?• Organizing terms around core concepts in a business, domain or
enterprise
• Goals:*– Articulate clear and concise meanings of business domain
concepts– Achieve a shared understanding of the concepts among relevant
stakeholders, and– Guard the stability of a concept’s meaning during system
development• Major activities:*
– Scoping the environment of discourse– Concept specification, integration and enforcement

A Practical and Theoretical Perspective” 2003.

Concept Management Concept Management and the Semantic Weband the Semantic Web
The Semantic Web is an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation.
It is all about:
• Managing concepts• More explicit meaning• Structure and standards• Tools and infrastructure
Where do we want to go?Where do we want to go?• ETSS supports the ability to connect multiple
vocabularies:– Put an umbrella concept system over all the
vocabularies to which the individual terms can be linked
– Increase the links between terms, including across vocabularies
– Create richer relationships between terms– Continue to add definitions– Develop tools for comparing terms and
definitions
