    1. 1. 1<br />Semantic Web<br />By <br />Ramesh<br />
    2. 2. Proper Flight with good reputation<br />A trip to China!!! Wow<br />Intermediate Airline<br />Lowest Fare<br />Luxurious<br />Intermediate<br />Cheap<br />2<br />
    3. 3. Initial Phase<br />Chinese????<br />3<br />
    4. 4. Intermediate Phase<br />Languages<br />Specialized site<br />Social travel site<br />Images<br />4<br />
    5. 5. Final Phase<br />Searched<br />Merged<br />Sorted<br />5<br />
    6. 6. Is this what the site offers???<br />Data Base<br />6<br />
    7. 7. Web Of Data<br />Standard approach<br />Analogous approach<br />Publish Data<br />A.Com<br />****<br />not be forced to make targeted<br />developments<br />Pen Drive<br />Searching<br />some.Com<br />****<br />Pen Drive<br />7<br />
    8. 8. Web Of Data<br />DB1<br />DB2<br />DB3<br />8<br />
    9. 9. So semantic Web is..<br />Collection of Technologies<br />To Realize <br />“Web Of Data”<br />9<br />
    10. 10. Semantic Web<br />Web 2.0<br />Are they same????<br />Its all about people and communication<br />It is focuses on machines<br />10<br />Standard and Technologies<br />Collaboration and Sharing<br />
    11. 11. Semantic Web<br />World Wide Web<br />Are they Different????<br />WWW<br />Adds new data and metadata to existing Web documents<br />Extension of Web documents to data<br />Semantic Web<br />Extension<br />11<br />
    12. 12. So what it aims at???<br />In short aims at……….<br />The goal of the semantic web is to be “a web talking to machines”<br />I know What you mean……<br />Providing meaningful information<br /> Supplying the web with<br />formalized knowledge in addition to its actual informal content<br />Designing a framework for interoperability<br />accessible by computers.<br />12<br />
    13. 13. Requirements <br />Realization of a semantic web will require several layers of developments<br />Interoperability<br />Client Devices<br />Applications<br />Resources<br />Languages<br />Infrastructure<br />13<br />
    14. 14. Approaches to Semantic Web<br />2<br />BUSINESS & PROFESSIONAL<br />Electronic commerce<br />Bioinformatics<br />Knowledge <br />Biological data<br />WWW<br />Semantic Web<br />PERSONAL<br />Personalization<br />Gathering and filtering relevant information<br />14<br />
    15. 15. RDF<br />Building Blocks of Semantic Web<br />Semantic Web<br />Ontology<br />Knowledge Representation<br />Languages <br />Andinferences<br />15<br />
    16. 16. Resource Description Framework<br />RDF???<br />RDF???<br />METADATA<br />Describes<br />Developed under the guidance of the World Wide Web Consortium<br />Allow developers to build search engines that rely on the metadata<br />Developed by<br />Developed by<br />Providing interoperability among applications that exchange machine-understandable information on the Web<br />site&apos;s sitemap<br />dates of updates<br />Developed for<br />Developed for<br />16<br />
    17. 17. RDF provides a model for describing resources<br />RDF Data Model<br />RDF Description<br />Property Type3<br />Property Type2<br />Resource<br /> 2<br />Resource<br /> 3<br />Resource<br />Property Type4<br />Property Type1<br />“Atomic Value”<br />“Atomic Value”<br />17<br />
    18. 18. An example<br />Consider this statements<br />&quot;The author of Document 1 is David“<br />“David is the author of Document 1&quot;<br />Property-Type<br />Document1<br />Author<br />“David”<br />Value<br />Resource<br />18<br />
    19. 19. One step further<br />Document1<br />Author_001<br />Author<br />Email id<br />Company<br />Name<br /><br />Some ltd<br />David<br />19<br />
    20. 20. Ontologies<br />An ontology is a formal conceptualization of a domain that is usable by a computer<br />involves an explicit description of <br />domain structure<br />terms used to describe the domain<br />20<br />Allows applications to agree on the terms when communicating<br />
    21. 21. Ontology <br />lifecycle<br />Conceptual Refinement<br />Initial Design<br />Evaluation<br />Requirement analysis<br />Evolution<br />Ontology<br /><ul><li>Formal evaluation
    22. 22. Agreement between ontologies
    23. 23. Semi-automatic mechanism
    24. 24. Deployment
    25. 25. Maintenance
    26. 26. Management
    27. 27. Creating Domain
    28. 28. Analyzing the resources
    29. 29. Competency </li></ul> questions,<br /><ul><li>Creating Reusable Domain
    30. 30. Lack of tools
    31. 31. Key issue- Specificity and reusability</li></ul>21<br />
    32. 32. Languages and inferences<br />“languages are necessary for expressing the content of the<br />semantic web”<br />Inference Engines<br />Languages<br />Standardizing syntax<br />Precise Semantics<br />22<br />
    33. 33. Major Challenges in Languages<br />Different modeling styles<br />Logic<br />Objects<br />Constraints from AI<br />View-Queries<br />Identity <br />Non-ambiguous names-URI<br />Identifying objects of same domain<br />Modularity<br />Re-use of resources<br />Extracting of section on ontology<br />23<br />
    34. 34. 0<br />24<br />Knowledge Representation<br />Automated reasoning<br />DB1<br />sets of inference rules <br />Structured collections <br />of information<br />
    35. 35. 25<br />Two section will be benefited when semantic web evolves<br />A for????????<br />
    36. 36. 26<br />Thank you<br />
