Rdf and open linked data a first approach

  1. 1. RDF and Open Linked Data, a first approach <ul><li>ADLUG Users Group Meeting </li></ul><ul><li>Trento , 22 - 24 September, 20 10 </li></ul><ul><li>Tiziana Possemato, @C ult Andrea Gazzarini , @Cult Ádám Horváth , NSZL </li></ul>
  2. 2. Contents <ul><li>Open Linked Data </li></ul><ul><li>ThGenius </li></ul><ul><li>Thesaurus management in WeCat </li></ul><ul><li>Keyword search enrichment </li></ul>
  3. 3. Chalanges for libraries <ul><li>Les and les people use library catalogues </li></ul><ul><li>What could be the answer </li></ul><ul><ul><li>To bring the catalogue to the surface web </li></ul></ul><ul><ul><ul><li>To make it searchable by Google </li></ul></ul></ul><ul><ul><li>To provide your data where the user is </li></ul></ul><ul><ul><ul><li>The user must be able to get library data in social sites </li></ul></ul></ul><ul><ul><ul><li>To provide your data on mobile equipments </li></ul></ul></ul>
  4. 4. Challenges for libraries <ul><li>New potential user: the web and the services on the web </li></ul><ul><ul><li>Our services must not only be on the Web, but need to be of the Web </li></ul></ul><ul><ul><li>We have to publish our data on the semantic web </li></ul></ul><ul><ul><li>We can use semantic web technologies </li></ul></ul>
  5. 5. Some introductory notes <ul><li>Semantic web is often called </li></ul><ul><ul><li>Linked Data </li></ul></ul><ul><ul><li>Open Linked Data </li></ul></ul><ul><ul><li>Linked Open Data (LOD) </li></ul></ul><ul><ul><li>the web of Linked Open Data </li></ul></ul>
  6. 6. Web and semantic web <ul><li>Web links pages </li></ul><ul><li>Semantic web links data </li></ul><ul><li>Web is like a document </li></ul><ul><li>Semantic web is like a database </li></ul><ul><ul><li>RDF is the data format of the database </li></ul></ul><ul><ul><li>This database is independent from any application </li></ul></ul><ul><li>Web is for human beings </li></ul><ul><li>Semantic web is for machines </li></ul>
  7. 7. Advantage of linked data <ul><li>Linked data provides a single, standardised access mechanism </li></ul><ul><ul><li>Linked data is a single worldwide API </li></ul></ul>
  8. 8. Advantage of semantic web technologies <ul><li>Certain tasks can be carried out easier with semantic web technologies </li></ul><ul><ul><li>RDF database + SPARQL = very powerful search capabilities </li></ul></ul>
  9. 9. Linked data from library perspective <ul><li>Libraries can share data in a non library centric way </li></ul><ul><li>Libraries can share their data in a web friendly way </li></ul><ul><li>Library’s data can be meaningful in a new context </li></ul>
  10. 10. The role of libraries in building the semantic web <ul><li>The libraries have to publish their data on the semantic web </li></ul><ul><li>Software developers have to develop applications that use the (published) semantic data </li></ul><ul><li>Libraries can use semantic web technologies, applications to solve certain tasks more efficiently </li></ul><ul><li>Library vendors can help on both sites </li></ul>
  11. 11. Libraries publishing linked data <ul><li>Entire library </li></ul><ul><ul><li>LIBRIS </li></ul></ul><ul><ul><li>National Széchényi Library (NSZL) </li></ul></ul>
