1. Measurement Semantics: “MEASEM”
Semantics WG report
Measurement Semantics: “MEASEM”
D1 AHM, Park City, UT May 15, 2014
Presenters: Mark Schildhauer & Xixi Luo

2. Participants Mark Schildhauer Xixi Luo Line Pouchard
Deborah L. McGuinness (remote)
Margaret O’Brien (remote)

3. Ontology Design Patterns (ODPs) for Observations and Measurements
All W3C OWL: OBOÉ (ecology), EQ/PATO (genomics), O&M (OGC, ISO 19156)

4. Focus of D1 Semantics in Phase II
Semantics of Measurements:
...binding raw data values to concepts drawn from ontologies
...often through metadata
...using W3C standards for annotation--
PROV, OA
...to facilitate resource discovery and interpretation through enhanced precision and recall of searches

5. Tools for Semantic Annotation of Measurements
Semanteco
annotation of CSV’s
OBOÉ design pattern
D1 Phase I product, and other ongoing work at RPI...
GITHUB, Web interface available

6. Tools for Semantic Annotation of Measurements
annotating EML-described data objects
OBOÉ design pattern
D1 Phase I product, and ongoing work of NCEAS, LTER, others

7. PHASE II: MEASEM, PROV, and MsTMIP*
Focus on semantic clarification of MsTMIP data:
Measurements as expressed in Model Outputs and Observational Data
Clarify definitions and inter-relationships among Measurements
Develop Ontologies with relevant Concepts
Annotate MsTMIP data products to Ontologies (tools needed!)
Develop UI’s enabling enhanced Precision and Recall in searches
Expect enhanced interpretation of variables by Broader Community
PROV and MEASEM WG both using W3C Semantic approaches
Shared technology infrastructure, tools, and syntaxes (onts, annotations)
* MsTMIP== Multi-scale Synthesis and Terrestrial Model Intercomparison Project

8. MEASEM, PROV, and MsTMIP

10. MEASEM and MsTMIP

11. MEASEM and MsTMIP
Possibly also develop semantic “Taxonomy of Models”?

12. Phase II MEASEM participants
Deborah L. McGuinness, Mark Schildhauer (co-leads)
Postdoc (Xixi Luo)
Matthew Jones (CCIT link)
1~2 software engineers (Ben Leinfelder, CCIT, +?)
Margaret O'Brien
two grad student interns
Additional members? (Pouchard, BFO rep, ESIP rep?)
close interactions: PROV WG and MsTMIP Use Case
