  • Developing a Web-based RDF VisualisationFramework and Instantiating it as a PublicationVisualisation ServiceAufbau eines webbasierten RDF-Visualisierungsframeworksund Instanziierung als sächsischer Publikations-VisualisierungsdienstJan Polowinski, June 11th 2013jan dot polowinski at gmail dot comHTWK Leipzig / IMN
  • 2/26Outline• Motivation• Summary of the project context• Current status of the project• Next steps
  • 3/26(Assumed) Problems in Literature Search• Information Overflow in the field of publications• Relevant Papers can be overlooked• Hard to judge: When to stop?
  • VISUALISATION4/26
  • 5/26HypothesisToday‘s visualisation tools are not actually used byresearchers in their daily literature search, becausethey suffer from the following technical/politicalproblems:
  • Problems6/26„Silos“ of data:Lack of linked open bibliographic data servicesNot all visual means exploitedCitationgraphs are rarely availableand not typed
  • General Goal: Improve and Speed up ScientificResearch by VisualisationLiterature searchers can• Overview new fields• Identify „best“ documents• Understand document contextLibrarians, writers of project proposals can• Classify new documents• Spot neglected research areas7/26
  • Web-basedVisualisationFrameworkforeScienceInstantiateProject Context –PHD Project by Jan Polowinski on Ontology-DrivenGuided Visualisation for RDS/OWL Data
  • IMPLEMENTATIONANALYSISCurrent Status of the Project• Instantiation of the approach as a web-based framework (eViss)9/26
  • IMPLEMENTATIONANALYSISCurrent Status of the Project• What data to visualise?• How to visualise effectively?• Preparing and executing a survey• Instantiation of the approach as a web-based framework (eViss)10/26Source: http://cluster.cis.drexel.edu/~cchen/citespace/
  • Survey: How do Researchers at TU Dresden do(Electronic) Literature Search?• supported by• Sächsische Landesbibliothek – Staats- und Universitätsbibliothek Dresden (SLUB)• Institut für Kommunikationswissenschaften, TUD11/26
  • SurveyPreparation andExecution• 2 groups:• Students• Research Staff• -12/26
  • Experienceswith existingvisualisations• Are they used?• Are users satisfied?• -13/26
  • Context-Questions• Media Usage• Do researchersprefer electronicor print media forreading / takingnotes /reviewing?• ResearchExperience• -14/26
  • Survey – Results• Completed questionaires• 941 from 1254 (Students)• 279 from 338(Research Staff)• 477 additional (free text)comments Great interest• First results ...15/26
  • Students: Do you Know / Use CiteSpace(a complex visualization suite for citation data)16/263%>1 %I don‘t know itI know, it but I don‘t use itI use it
  • IMPLEMENTATIONANALYSISCurrent Status of the Project• What to visualise?• How to visualise effectively?• Preparing and executing the survey• Instantiation of the approach as a web-based framework (eViss)17/26
  • Implementing the eViss Framework for the eSciencePlatformBasis: OntoWiki• Web-based editor for RDF• Developed at Uni Leipzig (2006)+ Plugins• Guidance for effective visualisations• Generating visualisations (based on D3.js)• Supported by Student work of Pooran Patel18/26
  • 19/26• Manage and editvisualizationsettings
  • Plug-In: Guidance for Effective Visualisationsby Error Messages and Warnings20/26
  • Plug-In: Generating Graphics- Collapsible Tree21/26
  • Plug-In: Generating Graphics – Tree Map22/26
  • Plug-In: Generating Graphics– Simple Composition23/26• Lightness• Shape• Size
  • Summary and Conclusion• We instantiated a highly flexible visualisationapproach for the eScience platform as eViss• Use eViss for publication data• Linked Publication Data Sources are emergingright now but not yet fully usable• Survey is a contribution on ist own: Many insightson how literature search is done today24/26
  • IMPLEMENTATIONANALYSISNext Steps• What to visualise?• How to visualise effectively?• Preparing and executing the survey• Completing the survey evaluation• Drawing conclusion for the choice ofgraphics• Instantiation of the approach as a web-based framework (eViss)• Setting up the Framework for publicationdata• Preparation of suitable graphicrepresentations25/26
