For the ?rst time four workshops have been held in conjunction with the 8th Object-Oriented Information Systems conference, OOIS 2002, to encourage - teraction between researchers and practitioners. The four selected workshops were fully in the spirit of a workshop session hosted by a main conference.

Managing Specialization/Generalization Hierarchies.- Managing Specialization/Generalization HIerarchies.- “Real World” as an Argument for Covariant Specialization in Programming and Modeling.- Maintaining Class Membership Information.- Hierarchies in Object Oriented Conceptual Modeling.- Specialization/Generalization in Object-Oriented Analysis: Strengthening and Multiple Partitioning.- Towards a New Role Paradigm for Object-Oriented Modeling.- Analysing Object-Oriented Application Frameworks Using Concept Analysis.- Using Both Specialisation and Generalisation in a Programming Language: Why and How?.- Automatic Generation of Hierarchical Taxonomies from Free Text Using Linguistic Algorithms.- Guessing Hierarchies and Symbols for Word Meanings through Hyperonyms and Conceptual Vectors.- Reuse in OO Information Systems Design.- Reuse in Object-Oriented Information Systems Design.- Software Reuse with Use Case Patterns*.- Promoting Reuse through the Capture of System Description.- A Specification-Oriented Framework for Information System User Interfaces.- The Role of Pattern Languages in the Instantiation of Object-Oriented Frameworks.- IS Components with Hyperclasses.- Collaborative Simulation by Reuse of COTS Simulators with a Reflexive XML Middleware1.- Efficient Web-Based Information Systems.- Efficient Web-Based Information Systems.- Semantic Integration and Query Optimization of Heterogeneous Data Sources*.- Extracting Information from Semi-structured Web Documents.- Object-Oriented Mediator Queries to Internet Search Engines.- Warp-Edge Optimization in XPath.- A Caching System for Web Content Generated from XML Sources Using XSLT.- Finding Similar Queries to Satisfy Searches Based on Query Traces.- WOnDA: An Extensible Multi-platform Hypermedia Design Model.-Model-Driven Approaches to Software Development.- Model-Driven Approaches to Software Development.- Executable and Symbolic Conformance Tests for Implementation Models (Position Paper).- Object-Oriented Theories for Model Driven Architecture.- Systems Engineering Foundations of Software Systems Integration.- Using the Model Paradigm for Real-Time Systems Development: ACCORD/UML.- Generating Enterprise Applications from Models.- Tool Support for Aspect-Oriented Design.- Model-Driven Architecture.- Model-Based Development of Embedded Systems.
