Tomáš Obšívač DTEDI 3/2011 Measuring Social Networks and Services The web is more a social creation than a technical one. The ultimate goal of the Web is to support and improve our web-like existence in the world. – Sir Tim Berners-Lee Big Picture Big Picture | Semantic Web | Social Web | My work  Intl. Information Infrastructure → World Wide Web → Giant Global Graph  Sir Tim Berners-Lee (2007)  http://dig.csail.mit.edu/breadcrumbs/node/215  GGG  ~ Semantic Web • W3C  And Social Web/Network? • Sociological term: Social Media  Methods and technologies to allow machines to understand the meaning of information on the Web.  Questionable feasibility of W3C approach (addresed by microformats)  Common framework that allows data to be shared and reused across applications.  Documents such as HTML page are readable by humans. Data are readable by machines.  Autonomous agents, metadata, relations  smarter than common web browsers or thermostat ;-)  RDF, ontologies, SPARQL, reasoning, …  Where are the people? And social interaction & dynamics? Semantic Web Big Picture | Semantic Web | Social Web | My work  DBpedia  A community effort to extract structured information from Wikipedia.  One of Linked Open Data's datasets  Friend of a Friend  FooF describe persons, their activities and their relations to other people and objects. Real World Examples Big Picture | Semantic Web | Social Web | My work  Media = channel or tool to deliver data ~ interaction.  One-to-one, one-to-many (mass media), many-to-many  User-generated content  Consumer generated media  Prosumer (A. Toffler, 1980, M. McLuhan 1972) • E.g. player generated content (common in RPG)  Value given by not so many to many • Participation inequality (aka 90–9–1 rule), e.g. Wikipedia: 99.8–0.2–0.003 J.
