How Google is using Linked Data Today and Vision For Tomorrow Thomas Steiner, Raphael Troncyand Michael Hausenblas Future Internet Assembly December 2010 Presented by: Dinesh Monteiro
Rich Snippets • Introduced by Google on May 12, 2009 • Display structured data in search results • Supports formats such as RDFa, Microformats and Microdata
Rich Snippets - Example <div xmlns:v="http://rdf.data-vocabulary.org/#" typeof="v:Event"> <a href="http://www.example.com/events/poisel_offenback.hmtl" rel="v:url" property="v:summary">Philipp Poisel in Offenbach</a> <span property="v:description">See Philipp Poisel in Offenbach</span> When: <span property="v:startDate" content="2011-01-16T19:00-01:00"> Jan 16, 7:00PM</span> <span property="v:endDate" content="2011-01-16T21:00-01:00"> 9:00PM</span> Where: <span rel="v:location"> <span typeof="v:Organization"> <span property="v:name">Capitol</span>,
Semantic Markup – Pitfalls • Incorrect labeling • Date as part of event description • Inclusion of unrelated words • “written by John Doe” • General confusion with what part of document to be marked up at all
Rich Snippets – A Vision for tomorrow • Query => “philipppoiselkonzerte” • Assume ticket sites have implemented Tickets Ontology foo:ticket a tio:TicketPlaceholder ; rdfs:label"Tickets for Philipp Poisel"@en ; tio:accessTo<http://data.events.example.org/123> . foo:ExampleTicketVendorgr:offersfoo:offer. foo:offer a gr:Offering ; gr:name"Tickets for Philipp Poisel in Bremen"@en ; gr:description"PhilippPoisel in Bremen"@en ; gr:includesfoo:ticket ; gr:hasBusinessFunctiongr:Sell ; gr:hasPriceSpecification [a gr:UnitPriceSpecification ; gr:hasCurrency"EUR"@en ; gr:hasCurrencyValue"24.10"^^xsd:float ; gr:validThrough"2010-11-11T23:59"^^xsd:dateTime].
Rich Snippets – A Vision for tomorrow • Bring the social experience into play • “Facebook experience” right into search experience • Decision based on friends decision
Multimedia Semantics • Provide richer video search results • http://example.org/video.webm?t=428,434#xywh=150,60,50,70&xywh=240,50,50,70
Triple-centric Networking • Thought experiment derived from Content-centric Networking • Contains Interest and Data packets
