  10. 10. Our Typical Domain Expert<br />Domain Experts, close to the business of our Clients<br />Highly Educated<br />Very Experienced<br />Respected in their Fields<br />But<br />No training in Formal Representation<br />Averse to “Technology”<br />
  11. 11. Business User Tasks in Modeling<br />HolyGrail: Editing<br />“Single step policyimplementation: Business changesitsownsystems”<br />But even more important<br />Reviewing<br />Dissemination/Communication<br />Explainingindividual cases<br />Feedback<br />

  14. 14. Early attempts to incorporate language<br />Language-like triples<br />Adding language to relation<br />Concatenation of Multiple Triples<br />One of our typical users:<br />“I don’t think that sentence is correct…”<br />Editing by parsing triples out of these sentences<br />Typical reaction:<br />“I keep getting it wrong…”<br />HTML EXPORT<br />
  15. 15. Early attempts to incorporate language<br />Domain Specific Languages<br />Many are very syntax oriented<br />Typical Reaction: <br /> “That’s programming!”<br />
  16. 16. Early lessons learned<br />Free typing is not a great editing metaphor<br />Is it freedom if there is more wrong than right?<br />Limiting users in the number of ways things can be expressed is a good thing<br />Consistency and quality<br />No need to make choices at every sentence<br />Guidelines are needed to avoid ambiguity<br />For instance from SBVR/Rulespeak<br />
  17. 17. IntroducingPatternSentences<br />Sentence Parts mapping to triple types in formal graph<br />Static Text<br />Introduction of concepts (Objects)<br />References to concepts (Subjects)<br />Editing operations based on pattern sentences<br />Choosing sentence parts<br />Name an introduced concept<br />Choose an existing concept to refer to<br />
  18. 18. WhyPatternSentences<br />Bridge the gap between formal and natural approach<br />The underlying model is the formal graph<br />The sentences are hand made for comprehensibility<br />Based on best practices in the BR community like RuleSpeak<br />Based on NLG<br />No parsing: on editing, widgets are NLG-ed in<br />Provides freedom in choosing pattern sentences<br />Ability to embed “explanation” inside the pattern <br />Example: next slide<br />
  19. 19. Example<br />A customerappliesfor the Triple Play by ordering all of the products Digital TV, Fast ADSL and BasicTelehony<br />
  20. 20. Additional Advantages<br />Pattern sentences on top of formal graph have other advantages<br />Multiple visualisations<br />Visual, tabular, textual<br />Multiple languages<br />Translated Patterns<br />Multiple target groups<br />Ie. Grammars for different Expert levels<br />
  21. 21. Demo: Textual Policy<br /> In telecommunications, triple play service is a marketing term for the provisioning of two bandwidth-intensive services, high-speed Internet access and television, and a less bandwidth-demanding (but more latency-sensitive) service, telephone, over a single broadband connection. Triple play focuses on a combined business model rather than solving technical issues or a common standard.<br />
  22. 22. Demo: The knowledge model<br />
  23. 23. Demo: The model driven service<br />
  24. 24. Demo: Reviewing based on Natural Language<br />4 februari 2008<br />24<br />
  25. 25. Demo: Business users write rules<br />
  26. 26. Demo: GrammarConfiguration<br />
  27. 27. RemainingChallenges<br />How to prevent large numbers of patterns<br />Language variations: <br />Inflectional morphology: Plurals,..<br />Other natural languages<br />Mathematical Expressions<br />Named things vs anonymous things<br />Extending/relating CNL’s like we extend/relate meta models<br />
