  1. Semantic Web and S2S Patrick West Tetherless World Constellation Rensselaer Polytechnic Institute

  2. Overview • What is the Semantic Web? • Why do we care about it? • How does it relate to Science Research? • Faceted Browsing • How can S2S help?

  3. The Semantic Web What do you think it is?

  4. The Semantic Web • Semantic Web is a group of methods and technologies to allow machines to understand the meaning - or "semantics" - of information on the World Wide Web.[1] • [1] http://en.wikipedia.org/wiki/Semantic_Web#cite_note-w3c_faq-0 • A web of data that can be processed directly and indirectly by machines. – Tim Berners-Lee

  5. Expressivity

  6. Ontology • An ontology defines a common vocabulary for researchers who need to share information in a domain. It includes machine-interpretable definitions of basic concepts in the domain and relations among them. Subject – Predicate – Object Triple

  7. Why an Ontology • Why would someone want to develop an ontology? Some of the reasons are: • To share common understanding of the structure of information among people or software agents • To enable reuse of domain knowledge • To make domain assumptions explicit • To separate domain knowledge from the operational knowledge • To analyze domain knowledge

  8. Components of an Ontology • Triples • Open World • Everything is a First-Class Citizen • Don’t need a single ontology to rule them all

  9. Faceted Browsing • Faceted browsing, also called faceted navigation or faceted search, is a technique for accessing information organized according to a faceted classification system, allowing users to explore a collection of information by applying multiple filters.

  10. BCO-DMO

  11. VSTO

  12. How can S2S help • S2S is a user interface framework that leverages the machine-readable semantics of data, services, and user interface components. • http://tw.rpi.edu/web/project/sesf/workinggroups/s2s/

  13. How can S2S help • Server side provides access to the data via web services. • Server side provides access to configured widgets • Predefined • Home grown • Client side uses the web services to populate each of the facets, which are built using the widgets.

  14. Conclusion • S2S is very configurable • S2S is very modular • S2S helps with the discovery of data within a repository • S2S uses standard web protocols (HTML, CSS, Jquery, JSON, JavaScript, Opensearch, ontologies)

  15. Questions • Contact: Patrick West, westp@rpi.edu • Resources • http://tw.rpi.edu/web/project/sesf/workinggroups/s2s/ • http://tw.rpi.edu/web/TWC-101/References • http://bit.ly/12MvzwD - Ontologies Come of Age

  16. Semantic Web Methodology
