1st International Workshop on Business Models, Business Rules and Ontologies (BuRO 2010)
(workshop co-located with the 4th International Conference on Web Reasoning and Rule Systems, RR2010, Bressanone/Brixen, Italy, September 22-24, 2010)
Description of the Workshop
It is a challenge in a business to enable the right people to interact in their own way with the right part of their business application. We distinguish between three views on the business organization: (1) the view of the business analyst using a formal and validated business model; (2) the view of the knowledge engineer via ontologies and rules, and (3) the view of the IT department via an operationalization in applications. We can glue these views together via an end-to-end point solution: (1) conceptualization and where possible acquisition of business models and their transformation into ontologies and rules; (2) their management and maintenance, and (3) the transparent operationalization in IT applications.
The vision at the heart of the Semantic Web is of high relevance in a business setting as well. The proposed workshop addresses the different issues that arise in a business that wishes to have a transparent and where possible and useful a semi-automatic transfer of knowledge present in business documents expressing, e.g., policies, to an IT operationalization. Moreover, the workshop tackles these issues from an holistic perspective, raising awareness for the overall picture, instead of focusing on stand-alone issues. E.g., although OWL is well-investigated it is unclear how business knowledge expressed in SBVR can be mapped to it. Another example is the W3C's RIF effort: although based on well-investigated rule paradigms, it is less well-connected to upper business layers: how to go from a formal business model to RIF rules and how to interact with derived ontologies?

Adventures of Two Little OWLs in Rule Land
Markus Kroetzsch, Oxford University Computing Laboratory
Abstract: Combining ontological and rule-based modelling can be an onerous task, from the choice of a suitable semantic framework (there are quite a few) to the selection of a chain of tools for supporting it (there are just a few). Typical solutions combine not only the advantages but also the difficulties of both domains, especially regarding computational complexity. For the recently introduced light-weight profiles of OWL 2, however, the situation is remarkably different. Here we find that existing rule-based systems can rather easily be adopted to support ontological inferencing using established algorithmic methods. This is well-known for OWL RL – “RL” is for “Rule Language” after all – but much less so for OWL EL.

Combining Nonmonotonic Knowledge Bases for Modular and Distributed Knowledge-Based Information Systems
Thomas Krennwallner, Vienna University of Technology
Abstract: The developments in information technology during the last decade have been rapidly changing the possibilities for data and knowledge access. To respect this, several declarative knowledge representation formalisms have been extended with the capability to access data and knowledge sources that are external to a knowledge base. Such knowledge sources can come in various forms and may be as simple as a query interface to a database up to a full-fledged knowledge base.
In this talk we present two formalisms that that are centered around Answer Set Programming and have been designed with multiple knowledge bases in mind. One is modular nonmonotonic logic programs (MLP), which take up the issue of combining modules of logic programs into a coherent framework. The other formalism is multi-context systems (MCS), which are concerned with integrating knowledge from heterogeneous and possibly nonmonotonic knowledge bases (the contexts) using bridge rules, and combine them to a system with a semantics for contextual reasoning. We will argue that MLPs have the potential to host other formalisms that are relevant for the Semantic Web, like hybrid languages that combine ontologies and rules. MCS on the other hand are well-suited for distributed scenarios, where we can only assume an interface to contextualized knowledge bases---e.g., description logic or default theories---and do not get access to the actual content of the individual context. Heterogeneous nonmonotonic multi-context systems and modular nonmonotonic logic programs provide a basis for advanced knowledge-based information systems, which are targeted in ongoing research projects. They have been developed by the KBS group of the Vienna University of Technology in cooperation with external colleagues.

Using OWL in Ontology-based data integration
Domenico Lembo, Sapienza Universita of Rome
Abstract: Data integration is the problem of providing a single interface and unified mechanisms to access data stored in several autonomous, possibly heterogeneous, information sources. This is a challenging task in many IT applications, such as enterprise information management and data warehousing, as well as in scenarios like e-science, e-government, and web data management. In the context of the Semantic Web, data integration has been often faced through the adoption of shared conceptualizations of the domain of interest referred to as ontologies, with the aim of posing the semantics of the application domain at the center of the scene. It is therefore interesting to analyze which are the implications of using ontologies in data integration, and in particular of adopting Semantic Web languages, such as OWL, within the traditional architecture for data integration. According to such architecture, a data integration system is composed by a global schema, which represents the interface towards the user, a source schema, which models all the sources to be integrated, and the mapping between the two.
Short Bio: Domenico Lembo is assistant professor at the Department of Computer and System Sciences of the SAPIENZA University of Rome. His research interests concerns mainly information integration, Description Logics, Ontologies and the Semantic Web, inconsistency-tolerance in information systems. He authored more than 50 publications on the above topics in international journals and conferences. He is the author of several tutorials in the areas of data integration, ontologies, and the Semantic Web.
Incorporating regulations, business rules and other texts in the IT
François Lévy, Paris13 University
(involving material and ideas from A. Guissé, A. Nazarenko)
Abstract: Quite a lot of regulations available in texts impact everyday activities and are of interest in IT systems. Applicability of rights or duties to particulars (individuals or companies) is more easily answered with automated analysis of individual cases. Conformance of procedures to the many constraints that apply to organizations can benefit from automation (The conformance of organization procedures can be checked automatically, as soon as the relevant constraints are made explicit and formalized). This is the case for laws and regulations originating from official organizations as well as for internal regulations and business rules used in companies. Nevertheless, there is a critical bottleneck: analyzing regulatory texts to extract rules that the IT system will have to implement is still a challenging task. This is the topic of this talk.
Short Bio: François Lévy is full professor at Paris 13 university since 1993. He has been responsible of the french group ``Natural Language semantics'', working on logical representation of semantic and cognitive phenomena such as events, processes in narratives, and causality. He has also had some activities in default logic and in diagnosis.
The Entity-centric organization
Heiko Stoermer (Fondazione Bruno Kessler, Trento, Italy)
Abstract: Semantic technologies enable a shift from a schema-centric (or data centric) approach to data management in complex organizations to an entity-centric approach, where different data sources are viewed as potential providers of statements about relevant business entities (people, companies, products, locations, events, projects, etc.). We will argue that such a shift may enormously simplify the management of data and in particular their integration and exploration. This claim will be supported by a number of very concrete use cases where we have used this approach to solve very different issues and by showing why the entity-centric approach was better (along different dimensions) with respect to different and more traditional approaches.
Short Bio: Heiko Stoermer works as a researcher in the area of Entity-centric DIKM at Fondazione Bruno Kessler (FBK-irst), Trento, Italy. After studies in Linguistics he moved to the area of Computer Science, where he holds a German university degree. He gathered industry experience as a software consultant and project manager, and opted for an academic career in 2004 when he received a scholarship at the International Doctorate School in Trento. In 2008, he was awarded with a PhD for his work on Identity and Reference on the Semantic Web. His research interests include information integration, semantic interoperability and contextual knowledge representation. He has (co-) authored a number of scientific publications, acted as a reviewer for important international conferences, is co-organizer of several workshops, and steering committee member of the workshop series on Semantic Web Applications and Perspectives. Currently, he is devoting most of his time to his position as Technical Director of the European large-scale Integrated Project OKKAM, which he co-founded.
