2. Model and ontology based conceptual searching in legislative XML collections ITTIG-CNR Florence – Italy Carlo Biagioli, Fabrizio Turchi

3. metaSearch meta data searching software ● extract knowledge from provisions metadata ● based on standard XML-DTD (NiR project) ● metadata describe the semantics of the norm ● XML legal documents collection ● allow to query the functional profile of texts

4. metaSearch technologies ITTIG-CNR C.Biagioli – F.Turchi – xml technologies (sax, dom, xpath) – relational database – open source – xml native search engine (Xindice/Apache)

5. metaSearch asynchronous phase XML legal documents parser SAX Relational DB ITTIG-CNR C.Biagioli – F.Turchi

6. metaSearch asynchronous phase details – transfer metadata information into rdb – the goal is to build a metadata provision index to speed up the information retrieval

7. metaSearch meta data extraction ● sample xml markup:... notification everyone paragraph[@id=”art16-par2-let3”] Relational DB ITTIG-CNR C.Biagioli – F.Turchi

8. metaSearch interactive phase ITTIG-CNR C.Biagioli – F.Turchi – web interface (minimal requirements) – modules: ● webSearch (search form) ● webResults (browse list) ● webView (provision full text)

9. metaSearch interactive phase diagram webSearch Relational DB Legal Ontology webResults webView parser DOM XPath XML collection ITTIG-CNR C.Biagioli – F.Turchi

10. metaSearch queries samples ITTIG-CNR C.Biagioli – F.Turchi – obligation and penalty connected by a common action argument – obligation and claim connected by an addressee argument and a counterpart related argument

11. metaSearch relationship between provisions ● related provisions ● derogating provisions ● implicit provisions ITTIG-CNR C.Biagioli – F.Turchi
