  3. 3. Semantic web and the social web <ul><ul><ul><li>Brief introduction </li></ul></ul></ul><ul><ul><ul><ul><li>All materials available at http://del.icio.us/georgiawebgurl/semantic_web_presentation </li></ul></ul></ul></ul><ul><ul><ul><li>Semantic web </li></ul></ul></ul><ul><ul><ul><ul><li>Introduction </li></ul></ul></ul></ul><ul><ul><ul><ul><li>A little terminology </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Examples </li></ul></ul></ul></ul><ul><ul><ul><li>Social media and the semantic web </li></ul></ul></ul><ul><ul><ul><li>Challenges of the semantic web </li></ul></ul></ul>Robin Fay, robinfay.net 2009/10
  4. 4. Semantic web and the social web <ul><ul><li>Social media/social networking/social web </li></ul></ul><ul><ul><ul><li>Focus is on providing a user centered experience </li></ul></ul></ul><ul><ul><ul><li>Content created by users </li></ul></ul></ul><ul><ul><ul><li>Metadata frequently created by users in the form of assigning rights (creative commons such as at flickr), assigning metadata (tags, description) and more. </li></ul></ul></ul><ul><ul><ul><li>read/write web </li></ul></ul></ul><ul><ul><li>Semantic web, aka Web 3.0 </li></ul></ul><ul><ul><ul><li>Focus on data and harvesting </li></ul></ul></ul><ul><ul><ul><li>Machine driven; rules based </li></ul></ul></ul><ul><ul><ul><li>Relies on structure </li></ul></ul></ul><ul><ul><ul><li>Portal/personal web </li></ul></ul></ul><ul><ul><ul><li>Early early stages </li></ul></ul></ul>Robin Fay, robinfay.net October 2009
  5. 6. Semantic web and the social web <ul><li>So: </li></ul><ul><li>Web 1.0 = we used the web as a tool </li></ul><ul><ul><li>primarily html based; few database driven sites; little interactivity </li></ul></ul><ul><li>Web 2.0 = we interacted, enhanced, and controlled our experience </li></ul><ul><ul><li>Many database driven websites, search engines within websites, widgets, highly customizable </li></ul></ul><ul><li>Web 3.0 = we teach it, it learns </li></ul>Robin Fay, robinfay.net 2009/10
  6. 7. Semantic web and the social web <ul><li>The web as we know it (and think of it) links together documents (html, pdf, dynamic documents created from databases, etc.) </li></ul><ul><li>The Semantic web links together data. </li></ul>Robin Fay, robinfay.net 2009/10
  7. 8. Semantic web and the social web <ul><li>At its core, the semantic web comprises: </li></ul><ul><ul><li>a set of design principles, </li></ul></ul><ul><ul><li>collaborative working groups , </li></ul></ul><ul><ul><li>and a variety of enabling technologies. </li></ul></ul><ul><ul><li>Some elements of the semantic web are expressed as prospective future possibilities that are yet to be implemented or realized </li></ul></ul><ul><ul><li>Other elements of the semantic web are expressed in formal specifications </li></ul></ul><ul><ul><li>(wikipedia, 2009) </li></ul></ul>Robin Fay, robinfay.net 2009/10
  8. 9. Semantic web and the social web <ul><li>RDF = Resource Description Framework </li></ul><ul><li>RDFS = Resource Description Framework Schema </li></ul><ul><li>OWL = Web Ontology Language </li></ul><ul><li>URI = Uniform Resource Identifier </li></ul>Robin Fay, robinfay.net 2009/10 Many terms associated with the Semantic Web are used or based upon information architecture, database, and information science fields
  9. 10. Semantic web and the social web <ul><li>RDF = Resource Description Framework </li></ul><ul><ul><li>is a general-purpose language for representing information in the Web (a metadata data model ) </li></ul></ul><ul><ul><li>is a W3C specification </li></ul></ul><ul><ul><li>is a conceptual description </li></ul></ul><ul><ul><li>is based upon making statements about web resources (triplets) </li></ul></ul><ul><ul><li>More or less : XML </li></ul></ul><ul><ul><li>Think sentence structure : </li></ul></ul><ul><ul><ul><li>subject – predicate(verb)-object </li></ul></ul></ul><ul><ul><ul><ul><li>My dog eats dogfood. </li></ul></ul></ul></ul><ul><li> Let’s look at some examples </li></ul>Robin Fay, robinfay.net 2009/10
  10. 11. Semantic web and the social web Robin Fay, robinfay.net October 2009 RDF concept
  11. 12. Semantic web and the social web W3C model Simple RDF concept marked up
  12. 13. Semantic web and the social web <ul><li>So, we have the framework, but how do we apply it? </li></ul><ul><li>RDFS = Resource Description Framework Schema </li></ul><ul><ul><li>A schema is </li></ul></ul><ul><ul><ul><li>outline : a schematic or preliminary plan </li></ul></ul></ul><ul><ul><ul><li>A structure described in a formal language supported by the database management system ; in a relational database [such as MySQL), the schema defines the tables, the fields in each table, and the relationships between fields and tables. </li></ul></ul></ul><ul><ul><ul><li>a description of the structure and rules a document must satisfy for an XML document type </li></ul></ul></ul><ul><ul><ul><li>http://tinyurl.com/yj442vr (define: schema -- google) </li></ul></ul></ul>Robin Fay, robinfay.net 2009/10
  13. 14. Semantic web and the social web <ul><li>Popular choices for schemas include </li></ul><ul><ul><li>Creative Commons: embeds RDF into mp3s </li></ul></ul><ul><ul><li>FOAF (Friend of Friend) : address books, contact lists, etc. </li></ul></ul><ul><ul><li>MusicBrainz: music CD information </li></ul></ul><ul><ul><li>DC (Dublin Core): multi-format, cross domain </li></ul></ul><ul><ul><li>RDF Site Summary: anything with a RSS </li></ul></ul><ul><ul><li>Schemas are sometimes called vocabularies </li></ul></ul><ul><ul><li>There are many, many schemas…. </li></ul></ul>A couple of examples Robin Fay, robinfay.net 2009/10
  14. 15. Semantic web and the social web Robin Fay, robinfay.net October 2009 FOAF
  15. 16. Semantic web and the social web … okay so that doesn’t sound so bad …. But it can get even more defined… Robin Fay, robinfay.net 2009/10 Very Simple Dublin Core in RDF We can combine FOAF + DC
  16. 17. Semantic web and the social web <ul><li>OWL = Web Ontology Language </li></ul><ul><ul><li>invented to link ontologies which are classification systems </li></ul></ul><ul><ul><li>Attempts to define objects and their relationships </li></ul></ul><ul><ul><li>Different “flavors” </li></ul></ul><ul><ul><li>“ interpreted as a set of &quot;individuals&quot; and a set of &quot;property assertions&quot; which relate these individuals to each other” (wikipedia 2009) </li></ul></ul><ul><ul><li>Not a requirement </li></ul></ul>Robin Fay, robinfay.net October 2009
  17. 18. Semantic web and the social web Robin Fay, robinfay.net 2009/10
  18. 19. Semantic web and the social web It all fits together, though…. Being that this is data driven, we can query, using SPARQL, a standard query language. It all fits together except….
  19. 20. Semantic web and the social web <ul><li>Who is going to create all of this new data? </li></ul>Robin Fay, robinfay.net 2009/10 <ul><li>Libraries, museums, and other resources already have huge record sets of structured data for their resources. </li></ul><ul><li>Many social networking sites </li></ul><ul><li>(del.icio.us, flickr, etc.) create metadata. </li></ul>
  20. 21. Semantic web and the social web <ul><li>The social web is collaborative and a mix of human and machine derived data </li></ul><ul><li>For example, tags are assigned by humans, yet data about those tags is assigned by machines </li></ul>Robin Fay, robinfay.net October 2009 diagram source: http://web2.wsj2.com/
  21. 22. Semantic web and the social web <ul><li>Drupal (opensource content management system) is adding semantic web features ; Wordpress has a SIOC plugin </li></ul><ul><li>Dpbedia is project combining wikipedia and RDF </li></ul><ul><li>SIOC (Semantically –linked Online Communities) is the semantic web model for social media websites ; attempts to connect forums, blogs, & more </li></ul><ul><li>..but can this happen? Really? </li></ul>Robin Fay, robinfay.net October 2009
  22. 23. Semantic web and the social web <ul><li>The social web/social media/social networking is about people. Its focus has been less on standards, controlled vocabularies, RULES…. After all, here comes everybody… </li></ul><ul><li>..but that is not exactly true. In order for blog posts to display sequentially, in order for discussions to be threaded, there must be an underlying order – a structure -- rules. </li></ul>Robin Fay, robinfay.net 2009/10
  23. 24. Semantic web and the social web <ul><li>Much of the technology (databases, servers, etc.) already exists – at least for the initial stages of the semantic web. </li></ul><ul><li>A great deal of the criticism of the semantic web hinges on either artificial intelligence OR on human inability – in other words, the computers can’t learn and we won’t code correctly for the computers, either. </li></ul>Robin Fay, robinfay.net 2009/10
  24. 25. Semantic web and the social web <ul><li>In order for the semantic web to reach its potential: </li></ul><ul><li>We need smarter computers. </li></ul>Robin Fay, robinfay.net 2009/10 <ul><li>We need better web standards. </li></ul><ul><li>We need a better behind-the-scenes structure (RDF). </li></ul><ul><li>We need more built in metadata generation tools on social networking sites. </li></ul><ul><li>We’ll need better search engines </li></ul>
  25. 26. Semantic web and the social web <ul><li>Let’s look at a few semantic search engines </li></ul><ul><ul><li>http://hakia.com/ </li></ul></ul><ul><ul><li>http://www.exalead.com/search/ </li></ul></ul><ul><ul><li>http://www.yr-bcn.es/demos/microsearch/ </li></ul></ul>Robin Fay, robinfay.net October 2009
  26. 27. Semantic web and the social web <ul><li>Questions? Thoughts? </li></ul><ul><li>Many many links @ </li></ul><ul><li>http://del.icio.us/georgiawebgurl/semantic_web </li></ul><ul><li>Presentation also at slideshare.net/robinfay/ </li></ul>Robin Fay, robinfay.net October 2009
