A comprehensive semantic framework for data integration systems

TL;DR: In this paper, the notion of consistent answer to a global query in the context of the local-as-view approach to data integration is characterized and a methodology for generating query plans for retrieving consistent answers to global queries is introduced.

TL;DR: This paper briefly reviews the recent literature on consistent query answering, an approach to handle database inconsistency in a systematic and logical manner based on the notion of repair, and summarizes selected research directions in this area.

TL;DR: A novel hybrid strategy combining Bayesian optimisation and common adaptive techniques is proposed to automatically adapt Multi-Component Predictive System (MCPS) and the feasibility of applying such automatic techniques for building and maintaining predictive models for real chemical production processes is evaluated.

TL;DR: In this article, the authors extend earlier work by its authors on formal aspects of the processes of contracting a theory to eliminate a proposition and revising it to introduce a new proposition.

TL;DR: The tutorial is focused on some of the theoretical issues that are relevant for data integration: modeling a data integration application, processing queries in data integration, dealing with inconsistent data sources, and reasoning on queries.

TL;DR: This paper shows that XML's ordered data model can indeed be efficiently supported by a relational database system, and proposes three order encoding methods that can be used to represent XML order in the relational data model, and also proposes algorithms for translating ordered XPath expressions into SQL using these encoding methods.
