Conference at a Glance

Pre-Conference Tutorials

PT1: Object-Process Methodology and Its Application to the Visual Semantic Web

Presented by
Dov Dori (Technion, Israel and MIT)

A comprehensive system modeling methodology with coherent ontology is essential for system architecting and engineering. Object-Process Methodology is a unifying approach for developing, communicating, supporting and evolving systems of various domains, types, magnitudes and complexities. OPM is founded on well-defined ontology with solid infrastructure; it has clear, formal, single-model semantics expressed bi-modally via graphics and natural language. It enables fast and reliable system modeling; and it caters to domain experts who are not IT professionals and therefore enables them to actively engage in the development process as part of the team. Taught at leading institutions of higher education and used in Industry, OPM has evolved as a significant extension of Object technology which caters equally well to systems' structure (through objects and relations) and behavior (through processes that transform objects). OPM encompasses the entire lifecycle of a software system or product, from concept and initiation through development to deployment.

The Visual Semantic Web (VSW) is a new paradigm for enhancing the current Semantic Web technology. VSW, which is based on OPM, provides for representation of knowledge over the Web in a unified way that caters to human perceptions while also being machine-processable. The advantages of the VSW approach include graphic-text knowledge representation, visual navigability, semantic sentence interpretation, specification of system dynamics, and complexity management.

This tutorial will present the underlying OPM ontology and its application for the Visual Semantic Web. It is based in part on material I have been teaching at MIT's Engineering Systems Division as well as the Summer Professional Institute.

PT2: Data Modeling using XML

Presented by
Murali Mani (UCLA, USA)
Antonio Badia (University of Louisville, USA)


XML is being used in different application scenarios:
  • XML has established itself as the standard for information exchange over the Web, and applications over the Web use XML for representing their information
  • XML is used for publishing data of traditional database applications as well as text applications over the web
  • XML is being tried as a logical data model: here, people come up with a conceptual model for database applications, and translate this conceptual model into logical XML model; the XML model might be stored in native XML databases or relational databases,
  • XML promises to be a good candidate for federated databases to provide a uniform view of multiple data sources.
Our tutorial will cover two application scenarios of XML: using XML as a logical model, and publishing relational data as XML. First, we will study how we can use XML as a logical model. We will describe the various options for structural specification for XML such as DTD, XML-Schema, RELAX NG, and also different options for constraint specification for XML such as XML-Schema and other research proposals. We will further describe the stages in the database design process -- coming up with a conceptual schema from real world applications, translating this conceptual schema into a logical schema, and translating this logical schema into physical schema. A conceptual schema is specified in a conceptual data model, such as ER, ORM, or UML. We will compare and contrast the important features of these conceptual models. We will then propose some extensions to ER model, and use this as our conceptual model. We will describe how a conceptual schema can be translated into logical XML schema and give examples. We will further describe what structural and constraint specification features are needed for using XML as a logical model. In the second half of the tutorial, we will describe translation between XML and relational models. We will cover different options for translating XML to relational and study existing systems in this regard.

Keynote Speakers

K1: Semantic Web Application Modeling

Erich Neuhold
Fraunhofer Institute for Integrated Publication and Information Systems (IPSI)
Germany
The Semantic Web and the Web service paradigm are currently the most important trends on the way to the next generation of the Web. They promise new opportunities for content and service provision, enabling manifold and flexible new applications and improved support for individual and cooperative tasks. The development of Web applications that can be operated effectively in the Semantic Web context, however, imposes some challenges. Two main challenges towards extended (conceptual) modeling support are addressed in this talk.
  • In the Semantic Web, Web applications move from a purely human user community towards a mixed user community consisting of humans as well as of software agents; this results into new requirements towards models for Web applications' user interfaces;
  • Automatic interpretation of content, one of the main building blocks of the Semantic Web, is based on interlinking local models with globally defined interpretation schemes like vocabularies and ontologies; this has to be reflected by the conceptual application domain models of Semantic Web Applications.
Conceptual Modeling for Web applications, thus, has to be revisited in the context of the new Web trends looking for adequate Semantic Web Application Models.

K2: Oh, That's What You Meant! The Interplay of Data Quality and Data Semantics

Stuart Madnick
Massachussetts Institute of Technology
USA
Data quality issues have taken on increasing importance in recent years. In our research, we have discovered that many "data quality" problems are actually "data misinterpretation" problems -- that is, problems with data semantics. In this talk, we first illustrate some examples of these problems and then introduce a particular semantic problem that we call "corporate householding." We stress the importance of "context" to get the appropriate answer for each task. Then we propose an approach to handle these tasks using extensions to the COntext INterchange (COIN) technology for knowledge storage and knowledge processing.

K3: Enterprise Information Integration -- XML to the Rescue!

Michael J. Carey
BEA Systems
USA
The database field has been struggling with the data integration problem since the early 1980's. We've named and renamed the problem -- heterogeneous distributed databases, multi-databases, federated databases, mediator systems, and now enterprise information integration systems -- but we haven't actually solved the problem. Along the way, we've tried data model after data model -- functional, relational, object-oriented, logical, semi-structured, you name it, we've tried it -- and query language after query language to go with them -- but we still haven't solved the problem. A number of startups have died trying, and no major software vendor has managed to hit a home run in this area. What's going on? Is the problem too hard? Should we just declare it impossible and give up?

In this talk, I'll explain why I believe now would be exactly the wrong time to give up. After a brief look at history, I'll make the case that we are finally on the verge of finding a real solution to this problem. I'll define the enterprise information integration problem as I see it and then explain how the XML and Web Services revolutions that are in progress -- based on SOAP, WSDL, XML Schema, XQuery, and so on -- relate to the problem and its solution. I'll describe the path that we are on at BEA to deliver a solution, and finally I'll leave the audience with my thoughts on some open problems where the database field, especially the "modeling crowd", can contribute.

IK: Workflow using AUML and Agents

James J. Odell
James Odell Associates
USA
Workflow provides a way to standardize processes and processing. For those organizations that have predefined ways of performing activities, workflow is a useful approach. Currently most workflow systems, however, employ a centralized form of coordination. For small systems, such an approach is possible; for large systems, centralized control would quickly paralyze the organization. One way to enable scalability of workflow systems is by using a distributed mechanism such as agents. This presentation describes how to develop agent-based workflow systems using UML -- for analysis, design, and execution. In other words, it describes a model-driven approach (MDA) for distributed workflow.

Conference Tutorials

T1: Understanding Metamodeling

Presented by
Brian Henderson-Sellers (University of Technology, Sydney, Australia)

Metamodelling underpins the UML both directly and in terms of the UML Profile Mechanism. This tutorial starts by explaining why metamodelling is important in the UML context and then evaluates the various aspects of metamodelling that are known to cause both practitioners and researchers the most problems. We explore the pros and cons of strict versus loose metamodelling, the notions of physical versus logical "instance-of" relationships and the various flavours of the "is-a" relationship (which include instantiation and generalization). These ideas are then applied to the UML context directly in an evaluation of the extension mechanisms of the UML, particularly stereotypes, and illustrated directly in terms of the metamodels currently underpinning not only the UML but also, as further examples, the OMG SPEM model for process metamodelling. This information will then permit developers of UML profiles to more successfully utilise the metamodelling aspects and know on which occasions it is better not to use metamodeling, in addition to providing end users with a greater capability to utilize the UML extension mechanisms.

T2: Data Analytics for Customer Relationship Management

Presented by
Jaideep Srivastava (University of Minnesota, USA)

Corporations across the world are recognizing that intimate, one-to-one relationships with their customers are critical for survival in the increasingly global and competitive marketplace. The ones which are proactive and quick footed, have taken the initiative to implement a Customer Relationship Management (CRM) system that integrates every area of business that touches the customer -- namely marketing, sales, and customer service -- by coordinating people, internal processes and technology.

A traditional CRM system typically focuses on reengineering the transactions and workflows to make them customer centric, however to gain competitive advantage it is equally important to analyze the business data for locating patterns in customer behavior that would help in customer acquisition, retention, and building customer loyalty. This can be achieved by coupling Data Analytics with traditional CRM.

The tremendous leaps in storage and computational power have made Data Analytics emerge as a powerful business tool that unleashes the power in your data across the organization for better decision making. Data Analytics combines data warehousing, data mining and mathematical modeling concepts to decipher previously unknown, actionable information from business data. Because the basis of data analytics is data -- the facts about what has already happened in the organization -- data analytics enables the organization to leverage the experience to make better decisions today.

This tutorial provides an up-to-date introduction to the increasingly important field of "Analytical CRM", whose goal is provide a quantitative basis for making CRM decisions -- thus leading the transition from customer relationship as an art to a science.
