Harmonising data definitions CEH Analytical Services Thesaurus (CAST) No specified vocabulary!
Making definitions open access CEH Analytical Services Thesaurus (CAST) Created to Simple Knowledge Organization System (SKOS) W3C standard Designed to describe whole process Top concepts: determinands machine descriptions measurement units methods filtration preservation
Resource oriented discovery CEH Analytical Services Thesaurus (CAST) SKOS allows links to externally hosted vocabularies e.g. ChEBI adds further value to datasets tagged using CAST, as they can be integrated with datasets tagged using concepts from linked vocabularies
Enabling complex environmental queries Web as a research data resource
Issues & challenges Researchers can ask complex questions across diverse data sources using LOD How to incentivise data providers to document & tag data => buy-in (e.g. DOIs)! Tools to automate the process, tagging at source/time of creation (e.g. LIMS) Automating the creation of semantic information for legacy data using diverse information sources (e.g. text mining of past reports and science papers)
