Transcript

  • 1. Linked Open Data Presented for the Penn Humanities Forum by Corey A Harper 2013-04-11 Tools and techniques for putting Metadata, Context, & Narrative On the Web @chrpr–[Slideshare]
  • 2. 2014-04-11 Harper - Penn Humanities Forum - LODLAM 2 The Web Becomes Semantic ● Originally: ● Metadata about “Web” things (documents) ● Eventually: ● Metadata about all sorts of things ● And about relationships between things ● TBL’s original vision (Weaving the Web – 1999) ● Then: Focus on Machine Reasoning ● Scientific American Article ● Now: Focus on things & links ● Reasoning & Inferencing less central
  • 3. 2014-04-11 Harper - Penn Humanities Forum - LODLAM 3 Semantic Web Terminology ● Resource: Any “thing” ● Class: Abstraction of a type of thing ● Individual: An instance of a class ● Property: An attribute of an individual ●Statement/Triple: ● A Resource (subject) ● A Property (predicate / verb) ● A Value (object) - Nodes ● Graph: Visual Representation of statements ● Ontology/Vocabulary: A domain specific collection of classes and properties
  • 4. 2014-04-11 Harper - Penn Humanities Forum - LODLAM 4
  • 5. 2014-04-11 Harper - Penn Humanities Forum - LODLAM 5 Linked Open Data ● Use URIs as names for things ● Use HTTP URIs so that people can look up those names. ● When someone looks up a URI, provide useful information. ● Include links to other URIs. so that they can discover more things. http://www.w3.org/DesignIssues/LinkedData.html
  • 6. 2014-04-11 Harper - Penn Humanities Forum - LODLAM 6 Linked Data ● Metadata as a Graph ● Typed “things”, named by URIs ● The relationships between those things, also built on URIs ● Ease of integration *across* data sources – “merging graphs”

  • 9. 2014-04-11 Harper - Penn Humanities Forum - LODLAM 9 DBpedia Structured Wikipedia Data ● Partial basis in data entry conventions ● InfoBox’s, and InfoBox Templates ● Metadata Entry Format ● Partial source of Ontology ● Class Structure ● Vocabulary Design
  • 10. 2014-04-11 Harper - Penn Humanities Forum - LODLAM 10 DBpedia ● 3.4 Million “things” described ● Ontology based on “infoboxes” ● 1.5 million things classified ● http://wiki.dbpedia.org/Ontology ● Approx. 50,000 “Properties” ● Approx. 1,200 defined in ontology

  • 25. 2014-04-11 Harper - Penn Humanities Forum - LODLAM 25 Annotations ● The Pundit (thepund.it) ● Hypothesis: Peer Review for the Web (hypthos.is) ● Open Annotation Collaboration ● Distributed bibliographic control environment ● Focus on identification over description “In short, by treating values as non-literal resources and assigning URIs to them we give ourselves (and others) the hooks on which to hang further descriptions.” - Andy Powell
