  • 1. Creating Knowledge out of Interlinked DataWP5 – Linked Data Browsing,Visualization, and Authoring Interfaces Sean Policarpio Digital Enterprise Research Institute National University of Ireland, Galway http://lod2.eu http://lod2.eu
  • 2. Creating Knowledge out of Interlinked DataWork Package 5 WP5• Our concerns: the browsing, visual representation, and creation of linked data.• Integration with the LOD2 project consists of components that present and create linked data and span across various application types and device mediums: – Spatial-based and faceted browsers, widgets – Social networking – Mobile device interfaces http://lod2.eu
  • 3. Creating Knowledge out of Interlinked DataWP5 Tasks & Deliverables Faceted Spatial- Adaptive Semantic Semantic Browsing Authoring Component WP5 Social Semantic Mobile Semantic Networking Interfaces http://lod2.eu
  • 4. Creating Knowledge out of Interlinked DataTask Breakdown 5.1 Faceted Spatial- Semantic Browsing • Concerned with the spatial-semantic browsing component Component 5.2 Adaptive • Widget based implementations and tools used for accessing and creating semantic-content in Semantic Authoring various environments 5.3 Social Semantic • Implementation of social networking interfaces Networking based on and connected to semantic-content 5.4 Mobile Semantic • A mobile interface for interacting with the Interfaces above tasks http://lod2.eu
  • 5. Creating Knowledge out of Interlinked Data5.1 Faceted Spatial-Semantic Browsing Component Initial Release Final Release Evaluation of of the Faceted Geo- of the Faceted the Browser Spatial Benchmarking Spatial- with the Semantic Definition Semantic Defined Browsing Browser Benchmark Component• A base-functional • A dataset benchmark • An extended and • Application of the prototype of the spatial- for spatial-semantic refined version of the benchmarking semantic browser queries and results initial release. definition to measure returned from the the browsers query browser answering effectiveness http://lod2.eu
  • 6. Creating Knowledge out of Interlinked DataThe Spatial-Semantic Browsing Component http://linkedgeodata.org http://lod2.eu
  • 7. Creating Knowledge out of Interlinked Data5.2 Adaptive Semantic Authoring • A widget component for the authoring of A Spatial semantic content. This Authoring is particularly concerned with the Widget Set faceted spatial- semantic browser. • A framework for the An Adaptive automatic creation of Widget widget interfaces for the creation and editing Choreography of semantic content. http://aksw.org/Projects/RDFauthor http://lod2.eu
  • 8. Creating Knowledge out of Interlinked DataThe Spatial-Semantic Browsers Authoring Widget http://linkedgeodata.org http://lod2.eu
  • 9. Creating Knowledge out of Interlinked Data5.3 Social Semantic Networking • An interface for the authoring components of The Subscription the LOD2 stack that informs and presents users and Notification with linked data Service • e.g. Notifications for changes/updates of Semantic Web data • Extend this interface to be Open-Social API utilised as a service with integration with the Open-Social API • Allows for connectivity with LOD2 Stack popular social networks http://docs.opensocial.org http://lod2.eu
  • 10. Creating Knowledge out of Interlinked Data5.4 Mobile Semantic Interfaces Faceted Spatial- Adaptive Semantic Semantic Browsing Authoring Component Widgets The Subscription and • Integration of the above components Notification Service into a mobile device format • E.g. the Android framework for cross-device support Mobile Semantic Interfaces http://www.android.com/branding/ http://lod2.eu
  • 11. Creating Knowledge out of Interlinked DataAdditional Integration Items: An Assisted SPARQL Query Editor• Based on a Data Graph Summary; a model that displays attributes such as entity and class linkage, property and class usage (cardinality), as well as other important statistical information for a particular graph of data (eg. RDF, RDFa, microformats).• Stored as an RDF graph so that it may be queried and utilised in conjunction with the datasets it represents.• Computed using a scalable, distributed computing system (i.e Apache Hadoop) for the purpose of producing summaries for very large sized data graphs. http://lod2.eu
