5 Stars Of Open Linked Data ϯ Star Rating Activity ★ make your stuff available on the web (whatever format) ★★ make it available as structured data (e.g. excel instead of image scan of a table) ★★★ Use non-proprietary formats (e.g. CSV instead of Excel) ★★★★ use URLs to identify things, so that people can point at your stuff ★★★★★ link your data to other people’s data to provide context ϯ

General Process

Financial - Landscape

Financial Model (Ontology)

Linking Financial Resources (Data Level)

RDFization of Form10-Q Financial Facts

Faceted Results.. -"type Company“ restricts results to those given the type (loosely, category) Company in the data" -"Industry Internet" which further restricts the previous sets to those assigned the value "Internet" to the property "Industry"

LOD Publication and Consumption* Compilation of tools and services for publishing and consuming Linked Data, such as:  RDFication: D2R framework, Triplify, any23  Link Discovery: Silk Framework, DL-Learner specify links to use in discovering relationships between LOD data items  Serving: D2R Server, Pubby, Triplify ‘RDB2RDF’ - mapping relational DBs to RDF (incl. Survey Report)  Data Crawling/URI smushing: any23, SIREn, Marbles, Semantic Web Client Library *LATC, - “To support institutions as well as individuals with Linked Data publication and consumption.” *LATC, - “To support institutions as well as individuals with Linked Data publication and consumption.”

Some DERI LOD Application Areas Linked Open Drug Data (Matthias Samwald)  - W3C WG includes participation by Johnson & Johnson, AstraZeneca Open Government Data (Richard Cyganiak)  - includes data sets from USA, UK, Australia, Canada, Sweden, New Zealand Library Linked Data (Jodi Schneider)  Linked Data For Sustainability (Edward Curry)  Financial Linked Data (Sean O’Riain)  Linking Enterprise Data for Business Intelligence

Open LOD Issues How to integrate new LOD into the LOD cloud – with addition of information rather than duplication?  Entity consolidation dbpedia:JohnSmith owl:sameAs bbcmusic:JohnSmith  Vocabulary alignment geonames:location owl:sameAs dbpedia:place How to identify the most fitting LOD resources for a particular application/domain?  Estimate application/domain semantics  Match application/domain semantics with LOD semantics
