  27. 27. LASSO and Refinder<br /><br />Use Case 3<br /><br />27<br />
  28. 28. Refinder: Collect, Curate, Communicate<br />28<br />40% of theworkforcein developedeconomies spend 45% of their time withinformationmanagement.<br />For them, Refinder isthenext-generationtoolto findtherelevantthings in theinformationoverflow.<br />Itismarketed as semanticenterprisesocialsoftware.<br />09.09.11<br /><br />
  29. 29. Communicate about social objects<br />29<br />09.09.11<br /><br />
  30. 30. Technology<br />30<br />09.09.11<br /><br />
  31. 31. Architecture<br />31<br />09.09.11<br /><br />
  32. 32. External Information Sources<br />Refinder uses external information sources<br />to enrich sparse user-provided data<br />to provide focal points around which social objects gather<br />Refinder is able to send rich queries to external data sources<br />based on social objects (“things”) <br />enriched with their attributes and context<br />32<br />09.09.11<br /><br />
  33. 33. Contextualized Social Objects<br />Context of objects consists of:<br />Static context:<br />Characteristics, attributes<br />Relations to other objects<br />User comments<br />Dynamic context:<br />Determined based on usage tracking<br />Optional user context elicitation module is under development<br />33<br />09.09.11<br /><br />
  34. 34. Integrating Linked Data<br />Refinder is able to load any kind of RDF descriptions about resources.<br />Refinder interprets rdf:type to determine how resources are displayed and ranked<br />Each resource is indexed <br />structured by property <br />fulltext<br />Share, comment, connect, … LOD resources<br />09.09.11<br /><br />34<br />
  35. 35. Example: Linked Open Data (DBpedia)<br />Refinder analyzes a social object and its context and generates a query that is sent to DBpedia.<br />Ranked results are presented to the user and can be imported and connected with one mouse click.<br />35<br />09.09.11<br /><br />
  36. 36. Example: Enterprise Thesaurus<br />Poolparty Thesaurus offers an extraction & recommendation API, powered by LASSO research results <br />Refinder sends contextualized queries to Poolparty and allows users to annotate social objects with thesaurus concepts<br />36<br /><br />09.09.11<br /><br />
  37. 37. LASSO Results in Refinder<br />Gnowsis work in LASSO focusses on the improvement of the recommendation precision.<br />Development of context elicitation algorithms<br />Static: analyze existing objects and their relationships<br />Dynamic: analyze user behavior and usage patterns<br />Integration of contextualized lookup and alignment services into the Refinder platform.<br />37<br />09.09.11<br /><br />
