Business people...• ... do not want to see or write this

Business people...• ... do not want to see or work with this• They are used – to look up glossaries – to apply regulations – to design policies – to write rules like « Customer must be 18 or more to rent a car » – to read decision tables

Glossary (from EU directive 77/541/EEC)

Business people want...• To write (and read, and manage) policies and rules using own or domain-specific language or lexicon – Natural language, not logic• Rules and policies communicated unambiguously across organisation’s or constituency’s branches, functions, domains – Same concepts, same semantics, different lexica• Rules and policies applied consistently accross organisation or constituency – Same rules, different applications

Same rule, different applications• Operative rules may instantiate differently in different applications – Policy: « Customer must be 18 or more to rent a car » – Decision: Can this customer rent a car? If this customer is 18 or more then proceed with rental – Decision: What shall I do to rent a car? If (today – birth) < 18 years then wait ((birth + 18 years) – today) years

Business people want...• To write policies and rules using own or domain-specific language or lexicon – Natural language, not logic• Rules and policies communicated unambiguously across organisation’s or constituency’s branches, functions, domains – Same concepts, same semantics, different lexica• Rules and policies applied consistently accross organisation or constituency – Same rules, different applications• ...and implemented as intended in decision-support IT applications• But rule engines need formal semantics and data models – Not natural languages and lexica

How to reconcile them?• Formalize vocabularies as ontologies – re-use accross application or implementation – Map to multiple data models – Attach to multiple lexica• Ground natural language policies and rules in formalized vocabulary – Formalize the additional semantics separately from the ontology• Operationalize in rule-based IT application – Translate formalized rules and policies into (possibly application specific) implementation-specific executable rules – Translate ontology into implementation-specific data model... – ...or ground executable rules into ontology

Additional benefits Separate (conceptual) domain knowledge from (operational) business rules... Separate domain knowledge from implementation dependent data model... Separate wide ranging policies from application specific operational rules ...that all have  Different lifecycles  Different scope (re-use etc)  Different owners Improving collaboration and quality  Design  Interchange, sharing, re-use, re-deployment (on different platforms)  Maintenance, evolution

Project ONTORULE: fact sheet 3 years Integrating Project funded by the European Commission  FP7, ICT call 3, theme 4.2 Current status: operation  Grant agreement: FP7 231875  Started: 1 January 2009  Duration: 36 months Overall budget: >8 M€  Max. funding: 5,4 M€  Effort: 644 person.months (~18 FTE) Consortium  Vendors: IBM (ILOG) + Ontoprise  SBVR consultants: PNA (+ John Hall)  Use cases: Arcelor Mittal + Audi  Technology center: CTIC  Academics: TU Vienna + FU. Bozen/Bolzano + U. Paris 13  Coordinator: Christian de Sainte Marie (IBM)

Key objectives and innovation Acquisition of ontology and rules from text Management of heterogeneous knowledge Combination of rules and ontologies at run-time Standard based integration End-to-end pilot applications www.ontorule-project.eu
