The Tetherless World Constellation introduces a groundbreaking Semantic eScience Framework (SESF) aimed at revolutionizing data integration and collaboration across diverse scientific disciplines. Originating from a 2004 virtual observatory project, this framework provides a toolkit for configurable, open-source semantic technologies. It fosters participation and collaboration among scientists by enabling seamless integration of various data sources, improving access control, and supporting complex queries. Join the community to be part of this transformative initiative and explore robust applications for environmental and marine science.

Transcription de la présentation

  1. The Semantic eScience Framework AGU FM10 IN22A-02 Deborah McGuinness and Peter Fox (RPI) pfox@cs.rpi.edu Tetherless World Constellation and the SESF team: Patrick West, Eric Rozell, Stephan Zednik, Cynthia Chang and Jim Hendler

  2. Introduction • The origins of this effort • Why a framework and not a system? • Moving from core semantics to framework semantics – integration and configuration • The design and development method • Open source ontologies and software! • A role for participation Tetherless World Constellation

  3. Origins • In 2004 we started a virtual observatory project based on semantic technologies • 2004 – OWL was a W3 recommendation!! • Use case driven – in solar and solar-terrestrial physics with an emphasis on instrument-based measurements and real data pipelines • We needed implementations – and we achieved that, also needed integration and provenance • We pushed semantics into applications that were already built on advanced cyberinfrastructure Tetherless World Constellation

  4. Prior to 2005, we built systems • Rough definitions • Systems have very well-define entry and exit points. A user tends to know when they are using one. Options for extensions are limited and usually require engineering • Frameworks have many entry and use points. A user often does not know when they are using one. Extension points are part of the design Tetherless World Constellation

  5. Lineage • Virtual observatories – semantic data frameworks, ontologies, reasoning, etc. • Semantic data integration • Semantic provenance • All very successful, but did not want to keep building more of these… • Lead to: need for a configurable framework … so that others could build theirs, easily… toolkit form Tetherless World Constellation

  6. Framework overview Tetherless World Constellation

  7. Core and Framework Semantics - Multi-tiered interoperability used by

  8. Semantics - Modern informatics enables a new scale-free** framework approach • Use cases • Stakeholders • Distributed authority • Access control • Ontologies • Maintaining Identity

  9. Real use cases: e.g.marine habitat - change Rock Several disciplines; biology, geology, chemistry, oceanography Several applications; science, fishing, habitat change, climate and environmental change, data integration Complex relations, questions Use case: What is the temperature and salinity of the water and are these marine specimens usual or part of an ecosystem change? Scallop, shell fragment Scallop, number, density Flora or fauna? Scallop, size, shape, color, place What is this? Dirt/ mud; one person’s noise is another person’s signal Src: WHOI and the HabCam group

  10. Modular semantics and applications – S2S see Rozell - IN23A-1349 Widget: a user interface element that visualizes results of S2S queries and facilitates user input (i.e., parameter selection) Query: a GET or POST service with parameters defined as S2S parameters Service: an OpenSearch- described resource that supports S2S queries Parameter: an input to S2S queries for requesting specific results

  11. Application integration! • Rozell et al. IN23A-1349

  12. Core and framework semantics

  13. Provenance aware faceted search Tetherless World Constellation

  14. Open Source • http://escience.rpi.edu/ontology/ • http://escience.rpi.edu/application/ - {null} • http://escience.rpi.edu/tool/ - {null} • SVN http://scm.escience.rpi.edu/svn • Application ontology approach (see Rozell et al.) provides the ability for user contributions to the framework (e.g. widgets) Tetherless World Constellation

  15. Participation • Current test-beds • VSTO reimplementation and HELIO • BCO-DMO (biological and chemical oceanography) • Ecosystem assessment • Want to join? • Community-based project collaboration site – you can request a login • Use case, requirements and framework use workshop in 2011 Tetherless World Constellation

  16. Summary • Ontology modularization efforts are well underway • Expansion of application integration via ontology-driven mediation • Non-specialist/ application use case implementation and vocabulary mediaiton • First phase of configuration capability coming by summer 2011 • Many opportunities to participate Tetherless World Constellation
