  2. The Cruel Reality Aspiration Reality • Zoom-able graph interface • Paper nodes / edges • Author nodes / edges • Information • Details per paper • Link to PDF • Facets • # inbound citations • Year range • Zoom-able graph interface • Paper nodes / edges • Information • Details per paper • Link to PDF

  3. Demo http://rosina.cs.washington.edu:8080

  4. Spatial Partitioning Node Positioning • Citations: • To graph: 10.1.1.35.5874  10.1.1.10.3314 10.1.1.87.6761  10.1.1.10.3314 10.1.1.110.8953  10.1.1.1.7533 10.1.1.42.1417  10.1.1.1.7533

  5. Usability (or lack thereof) • Spatial relationship is ambiguous • The graph cannot stand on its own • Still needs the list of results with words • Users can get lost in all the different nodes • Which ones do I care about? • Discovering is useful • But don’t show everything

  6. The Need for Speed

  7. The Need for Speed

  8. Lessons Learned • Many useful open source projects out there • Some are well-documented • Take advantage of sample code • Don’t always trust open source code • Don’t be afraid to fix bugs either • Java plug-ins for browsers are hard to work with • Flakey at times

  9. Surprise!! • CiteSeerX is very flakey • Lucene is pretty fast! • Lucene release cycle is ~2 weeks • Attu was a pain to work with • Permission errors • Connection refuse • Tomcat was hard to debug with • Error messages were not informative

  10. Where Credit is Due • Toshi • Cora data parsing • Relevance algorithm • Servlet API expansion • Tim • Data harvesting • Building index • Performance testing • Martin • UI development • Applet • Architecture design • Patrick • UI design • Usability testing • Architecture design
