SEMANTIC CIS: COMMUNITY INFORMATION SERVICES ON SEMANTIC WEB PLATFORM

  1. 1. SEMANTIC CIS: COMMUNITY INFORMATION SERVICES ON SEMANTIC WEB PLATFORM Barnali Roy Choudhury JRF, The Dept. Of Library & Information science The University of Burdwan
  2. 2. Semantic Web? “The Semantic Web is the extension of the World Wide Web that enables people to share content beyond the boundaries of applications and websites.” http://semanticweb.org/wiki/Main_Page
  3. 3. Tim Berners-Lee "a web of data that can be processed directly and indirectly by machines."
  4. 4. Semantic Web The vision of the Semantic Web is to extend principles of the Web from documents to data.
  5. 5. Purpose To enhance the evolution of the current Web by enabling users to find, share, and combine information more easily.The semantic web is a innovative way to disseminate information by which information can be readily interpreted by machines, so machines can perform more of the tedious work involved in finding, combining, and acting upon information on the web.
  6. 6. Informations are look like.... WWW2002 The eleventh international world wide web conference Sheraton waikiki hotel Honolulu, hawaii, USA 7-11 may 2002 1 location 5 days learn interact Registered participants coming from australia, canada, chile denmark, france, germany, ghana, hong kong, india, ireland, italy, japan, malta, new zealand, the netherlands, norway, singapore, switzerland, the united kingdom, the united states, vietnam, zaire Register now On the 7th May Honolulu will provide the backdrop of the eleventh international world wide web conference. This prestigious event … Speakers confirmed Tim berners-lee Tim is the well known inventor of the Web, … Ian Foster Ian is the pioneer of the Grid, the next generation internet …

  8. 8. Problems with HTML The World Wide Web is based mainly on documents written in Hypertext Markup Language (HTML), Is used for coding a body of text interspersed with multimedia objects such as images and interactive forms. Metadata tags provide a method by which computers can categorise the content of web pages.
  9. 9. Solution with Semantic Web The term "Semantic Web" is depends on some formats and technologies that promote it. The collection, structuring and recovery of linked data are promoted by technologies (are specified as W3C standards) that facilitate a formal description of concepts, terms, and relationships within a particular knowledge domain.
  10. 10. Solution with Semantic Web These technologies include: * Resource Description Framework (RDF), * RDF Schema (RDFS) is a framework for vocabulary * Simple Knowledge Organization System (SKOS) * SPARQL, an RDF query language * Notation3 (N3), designed with human-readability in mind * N-Triples, a format for storing and transmitting data * Turtle (Terse RDF Triple Language) * Web Ontology Language (OWL), a family of knowledge representation languages
  11. 11. COMMUNITY INFORMATION SERVICES “Services which assist individuals and groups with daily problem-solving and with participation in the domestics' process. The services concentrate on the needs of those who do not have ready access to other sources of assistance and on the most important problems that people have to face problems to do with their homes, their jobs and their rights.”
  12. 12. COMMUNITY INFORMATION SERVICES Survival Information such as that related to health, housing, income, legal protection, economic opportunities, political rights etc. Citizen action information, needed for effective participation as individual or as members of a group in the social, political, legal and economic process. Local information i.e., basic information concerning courses, educational facilities, government agencies, local organizations,fractional groups, health professionals etc. Including a calendar of local events.
  13. 13. BASIC CRITERIAS FOR SEMANTIC CIS Database(s); • Framwork; Cataloguing Rules; Vocabulary with Domain Specific IPSV(Integrated Public Sector Vocabulary); and • Ontology
  14. 14. ONTOLOGY? The term borrowed form Philosophy. A branch of philosophy that deals with the nature and the organisation of reality Science of Being (Aristotle, Metaphysics, IV, 1) Tries to answer the questions: What characterizes being? Eventually, what is being?
  15. 15. What is ONTOLOGY? “An ontology is a formal representation of a set of concepts within a domain and the relationships between those concepts. It is used to reason about the properties of that domain.”
  16. 16. Why? To share common understanding of the structure of descriptive information • among people • among software agent • between people and software To enable reuse of domain knowledge • to introduce standards to allow interoperability • to avoid repeated work
  17. 17. COVERAGE • • • • “Ontology” covers a range of things Controlled vocabularies – e.g. MeSH Linguistic structures – e.g. WordNet Hierarchies (with bells and whistles) – e.g. Gene Ontology • Frame representations – e.g. FMA • Description logic formalisms – Snomed-CT, GALEN, OWL-DL based ontologies • Philosophically inspired e.g. Ontoclean and SUMO
  18. 18. ONTOLOGY Three ‘flavours’ OWL-Lite –simple but limited OWL-DL – complex but deliverable (real soon now) OWL-Full – fully expressive but serious logical/computational problems
