The document outlines the concept of linked data, which enables structured data on the web to be published and connected through standards like URIs and RDF. It highlights the use of SPARQL for querying knowledge graphs and different vocabularies available for various data types. Additionally, it discusses the benefits of linked data in enhancing customer personalization and creating richer web experiences.

- 1. Linked Data Preview Jay Myers,
- 2. Every day we create 2.5 quintillion bytes of data (equivalent to 3.4 billion HD movies)
- 4. What if we could use these webs of data as a global DB?
- 5. Linked Data “A new form of Web content that is meaningful to computers will unleash a revolution of new possibilities” - TBL
- 6. Linked Data is: A set of standards for publishing and connecting structured data on the web.
- 7. Linked Data • Built on common web principles: HTTP, URIs, hyperlinks • URIs to identify data entities and relationships between things • Easily combine data sources
- 9. Built on RDF • “Resource Description Framework” • Model for data exchange on the web • Expresses relationships between things
- 10. The RDF “Triple” Entity - Attribute - Value or Subject - Predicate - Object
- 11. Linked Data Vocabularies • Schemas for the web of data • Distributed over the web (via URIs!) • Resolvable on the web for people to discover and learn how to use
- 12. Popular Open Vocabularies Name URI Description Bio http://purl.org/vocab/bio/ 0.1/ Describes biographical information about people, both living and dead FOAF http://xmlns.com/foaf/0. 1/ “Friend of a Friend”, describes social networks and person relationships FIBO In development “Financial Industry Business Ontology”, common vocabulary for financial terminology Good Relations http://purl.org/goodrelati ons/v1 Annotates product offers and products vCard http://www.w3.org/2006/ vcard/ns# Describes People and Organizations

- 16. Multiple RDF statements (and links!) connect to form graphs of data
- 18. Let’s query the web of data!SPARQL: SPARQL Protocol and RDF Query Language
- 19. SELECT Query prefix foaf: <http://xmlns.com/foaf/0.1/> select ?firstname ?lastname ?phonenumber from <http://jaymyers.com/jay/> from <http://davidwormald.com/david/> from <http://arunbatchu.net/arun/> where{ ?person foaf:givenname ?firstname ; foaf:lastname ?lastname ; foaf:phone ?phonenumber . } LIMIT 2 Namespace prefix Three fields Three data sources Specify conditions Return two
- 20. DBPedia Query PREFIX dbo: <http://dbpedia.org/ontology/> SELECT DISTINCT ?name ?person ?artist ?birth WHERE { ?person dbo:birthDate ?birth . ?person foaf:name ?name . ?person dbo:hometown <http://dbpedia.org/resource/Republic_of_Ireland> . ?person rdf:type <http://dbpedia.org/ontology/MusicalArtist> . ?person <http://dbpedia.org/ontology/associatedMusicalArtist> ?artist . } ORDER BY ?name Music artists whose birthplace is Ireland
- 21.

- 22. SPARQL nuggets • With SPARQL you can query knowledge graphs • SPARQL is to the Semantic Web and the Web in general what SQL is to relational databases • SPARQL is a W3C recommendation and is supported by many different database vendors (no vendor lock-in) • With SPARQL you benefit from the potential to make a collection of data sources look and query like one big database • SPARQL is also a standardized update and graph traversal language • SPARQL allows you to explore data • With SPARQL you can define inference rules to gain new information from existing facts “SPARQL is the new King of all Data Scientist’s tools”, Andreas Blumauer
- 23. Linked Data principles have surfaced in many places across the web
