  2. 2. WP6 <ul><li>Objectives </li></ul><ul><ul><li>Metaphorology </li></ul></ul><ul><ul><li>Evolutionary framework of languages </li></ul></ul><ul><ul><li>Knowledge visualization </li></ul></ul><ul><ul><li>Common Ontology for epistemic cultures </li></ul></ul><ul><li>Tasks : </li></ul><ul><ul><li>task 6.2: UniKassel  objective 1 </li></ul></ul><ul><ul><li>task 6.4: LSE  objective 2 </li></ul></ul><ul><ul><li>task 6.6: UniKassel, TUT, SUAS, LSE  objective 2 & 4 </li></ul></ul><ul><ul><li>task 6.8: ITA, UniZar, UniKassel  objective 4 </li></ul></ul><ul><ul><li>task 6.9: FAO, IITK  objective 2 & 3 </li></ul></ul>
  3. 3. Task 6.9 <ul><li>Title: Multilingual semantics in open knowledge systems for agricultural community of practice </li></ul><ul><li>Deliverable D6.10 : Multilingual Search Assistant (MSA) (Due M34 = 1 st April 2009) </li></ul><ul><li>Milestone M6.6 : Development of a Multilingual Search Assistant: challenges, experiences and the way to go (Due M30 = 1 st Dec 2008) </li></ul><ul><li>Partners : FAO and IITK </li></ul><ul><ul><li>Andy Bagdanov, Soonho Kim, Margherita Sini, Johannes Keizer </li></ul></ul><ul><ul><li>Jeetendra Singh, Ajay Krishnan, Prabhakar T.V. </li></ul></ul>
  4. 4. Deliverable D6.10: MSA <ul><li>Problems : </li></ul><ul><ul><li>current full text searches are based on frequency of text appearance, but this provides low precision and recall, since the tools don’t understand meaning; </li></ul></ul><ul><ul><li>for an efficient search users need to know what information is in the collection to select proper keywords. </li></ul></ul><ul><li>Objectives : helping users to find relevant documents using their own language </li></ul>

  6. 6. MSA: Use case navigate AGROVOC build boolean expression select multilingual and synonym expansion type term select boolean expression select language
  7. 7. MSA Component diagram MSSA API lucene index GUI User Results Lucene-based search engine get query set query Browsing component Boolean component (build boolean search) Multilingual component (expand languages and synonyms) GUI
  8. 8. System Workflow end start get query from search engine visualize AGROVOC browser with the query query null? visualize AGROVOC graphical browser (default value “agriculture”) NO YES is query string in agrovoc? YES NO user selects a term press ‘search” user selects boolean navigator user selects multilingual assistant send query to search engine visualize or update query string on search textbox
