Abstract

Many important applications in scientific fields such as Bioinformatics depend on the management of large collections of heterogeneous XML documents, containing complex domain-specific data. To allow advanced querying, these systems need to support techniques such as data exploration and approximate query processing by using multiple notions of similarity. The development of these kinds of information systems usually proceeds in costly ad-hoc ways, due to the lack of methodological guidance. This paper presents a model-based approach to guide the development of multi-similarity systems for XML document repositories. We describe the overall framework of our approach and in particular, we focus on the requirements phase. We provide a detailed guidance for capturing the users requirements and for specifying them in a formal way by using an adaptation of the i* modeling framework. Finally, the usefulness of our approach is demonstrated by a Bioinformatics case study.
