  • 1. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 1 of 26 Plone Conference 2010 Bristol Plone is so semantic, isn't it? Jens W. Klein <jk@kleinundpartner.at> 2010-10-28
  • 2. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 2 of 26 Store Knowledge? ● Humans have different kinds of knowledge: tacit and explicit ● only possible to transform explict knowlegde (brain) => reduce to information => store information in ICT-system ● creation of documents (html-form, doc, powerpoint, pdf, html, audio, video, CAD/CAM, and hundreds more) ● sometimes collaborative
  • 3. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 3 of 26 IN PLONE... ● create documents (HTML), ● upload or place links to documents. ● Excellent collaboration – sharing, – versioning, – workflow.
  • 4. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 4 of 26 Problem: ● stupid ICT-Systems: they dont 'know' anything about the document. ● we need to provide algorythms to fetch information from the ones and zeros. ● Algorythms are as good as stored information is ● Fulltext search: Cut into words, create index. ● Organize documents in folders, subfolder, give them meaningful names.
  • 5. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 5 of 26 IN PLONE... ● portal_catalog ● full text index and search ● hirarchical folderish structure
  • 6. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 6 of 26 BUT ... ● this is not enough. We want to know the author, intellectual property information, dates, ... ● So we need additional information. ● One solution: Store additional information with the document: Metadata. ● Dublin Core (DC) Metadata, Learning Objects Metadata (LOM), ..
  • 7. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 7 of 26 BUT ... lazy Humans! *sigh* ● metadata need to be created/added by editors. ● Humans are lazy, ● so must of the time – NO METADATA ENTERED ● Helpers: – Extrensic motivation (pay, required fields, ...) – Automatic adding out of context: i.e. username as creator, dates of creation or publishing.
  • 8. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 8 of 26 IN PLONE... ● Dublin-Core Metadata on any document. ● Some fields are filled automatically, – i.e.author, date of creation and publication, with some limits also language. ● Others need to be entered manually. ● Using add-on products utilizing schemaextender other metadata-fields can be added, i.e. the Dublin Core Terms extension. ● Exposed in HTML-header (if switched on)
  • 9. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 9 of 26 Semantics (from Greek sēmantikós) is the study of meaning. It typically focuses on the relation between signifiers, such as words, phrases, signs and symbols, and what they stand for. Wikipedia
  • 10. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 10 of 26 so no semantics so far in Plone? ● we have hierarchie – A is parent of B => relation ● we have metadata – John Smith is author of B – B was published 2010-10-10 10:10:10 ● we have general references – B is related to C
  • 11. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 11 of 26 Limitations in Plone ● If the word „Paris“ is in the text we dont know its a city „Paris is a city“. ● We can search for the string „Paris“, but not for articles about cities in france. „Paris is part of France“ ● No way to connect with articles outside Plone. ● Naked Plone only exposes a tiny set of its limited semantic information.
  • 12. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 12 of 26 RDF helps Resource Description Framework ● all information is broke down into triples of – subject => Paris – predicate => is part of – object => France ● triple is an element of a graph ● multiple triples forms complex RDF graphs ● RDF is family of W3C specifications to work with theses graphs.
  • 13. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 13 of 26 IN PLONE? ● No RDF dialect out of the box ● eea.rdfmarshaller (add-on) builds – RDF/XML from archetypes content, hierarchie and relations – RDF-Schemas from FTI ● no triple storage ● no possibility to query ● no auto-enhancement, i.e. finding geo-names

  • 15. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 15 of 26 Introducing IKS ● IKS (interactive knowledge stack, ICT-231527) is – a Semantic-based Open Source Platform for Small to Medium CMS Providers – raise the semantic capability of European software houses to develop intelligent content management solutions for their customers. – an Integrated Project (IP) of the European Union's 7th Framework Programme: ICT – Call 3. From 2009-01-01 to 2012-12-31 (48 months). – 13 participants from 7 countries involved, and the EC contribution is 6.57 million Euros (total cost: €8.55m). – http://[www|wiki].iks-project.org

  • 17. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 17 of 26 Introducing FISE ● FISE, a major IKS outcome, is – an Open Source RESTful Semantic Engine software component extracing meaning of electronic documents to organize it as partially structured knowledge. – semantic middleware with pluggable enhancers, – triple store, – sparql endpoint (query mechanism) – ... more to come – alpha, java, easy to integrate, nice devs behind.
  • 18. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 18 of 26 FISE current enhancers ● categorize documents, ● suggest meaningful tags from a controlled taxonomy and assert there relative importance, ● find related documents in the local database or on the web, ● extract and recognize mentions of known entities, ● detect yet unknown entities of the same afore mentioned types to enrich the knowledge base, ● more and more to come.
  • 19. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 19 of 26 not IKS, but related: Aloha-Editor ● WYSIWIG editor using Contenteditable (xHTML5) ● very fast (loading, init, multiple instances) ● pluggable - possible to create semantic plugins for i.e. microformats. ● OpenSource (GPL, initially made by Gentics) http://www.aloha-editor.com/
  • 20. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 20 of 26 YES. We need it in Plone. But: Out of my scope Who will integrate it?
  • 21. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 21 of 26 back to FISE: planned Python/ Plone Integration Klein & Partner KG got an IKS Early Adopter (funded) ● Create a generic Python API to communicate with FISE over its Restful API ● Integrate with Plone, „index“ into FISE. ● Create a Plone Portlet (UI) showing some enhancements. ● Present the results to the Plone Community. Spread the word.

  • 23. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 23 of 26 FISE Integration work done so far ● buildout for FISE http://github.com/collective/fise-buildout ● fise.client http://github.com/collective/fise.client ● started to spread the word ● research done: – RDFlib – SuRF – restful client APIs – SPARQL and Python
  • 24. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 24 of 26 fise.client Initialize: >>> from fise.client import FISE >>> fise = FISE('http://localhost:8080/') Use the engines: >>> somedoc = u"This is an example text." >>> fise.engines(somedoc) <xml...> >>> fise.engines(somedoc, format='rdfjson') jsonresponse Use the store, first store content (only plain text is accepted for now): >>> id = 'test123' >>> fise.store.content[id] = payload Next get the text back: >>> fise.store.content[id] u"This is an example text." Then get the metadata: >>> fise.store.metadata(id) <RDF> And FISE special feature: Get an HTML page about the content: >>> fise.store.page(id) <HTML>
  • 25. Creative Commons Namensnennung- Keine kommerzielle Nutzung- Keine Bearbeitung 3.0 Österreich LizenzPage 25 of 26 Work todo ● support passing SPARQL queries to FISE (easy) ● write fise.plone and index content in FISE. ● write some visualization (i.e. viewlet/ portlet) to show enhancement found ● document all this ● sprint on FISE in Bristol ● organize a semantic sprint in Innsbruck
