We describe a query-driven indexing framework for scalable text retrieval over structured P2P networks. To cope with the bandwidth consumption problem that has been identified as the major obstacle for full-text retrieval in P2P networks, we truncate posti ...
Refactoring of UML class diagrams is an emerging research topic and heavily inspired by refactoring of program code written in objectoriented implementation languages. Current class diagram refactoring techniques concentrate on the diagrammatic part but ne ...
Computational models of biological systems aim at accurately simulating in vivo phenomena. They have become a very powerful tool enabling scientists to study complex behavior. A side effect of their success Unfortunately exists and is observed as an increa ...

UML class diagrams are usually annotated with OCL expressions that constrain their possible instantiation. In our work we have investigated how OCL annotations can be automatically updated each time the underlying diagram is refactored. All our refactoring ...
This project proposes a new approach to interact with database systems through programming languages. A formal query language can be integrated within modern programming languages and the semi-structured queries can be evaluated using automatic transformat ...
The efficient tracking and tracing method for product lifecycle data is essential for avoiding any delays and errors affecting accuracy and completeness of enterprise applications, especially in the closed-loop PLM where several partners and organizations ...

In this paper, a visual language, VCP, for queries on complex-value databases is proposed. The main strength of the new language is that it is purely visual: (i) It has no notion of variable, quantification, partiality, join, pattern matching, regular expr ...
The impact of Peer-to-Peer (P2P) networks on the Internet landscape is undisputed. It has led to a series of new applications, e.g., as part of the so-called Web 2.0. The shift from the classical client-server based paradigm of the Internet, with a clear d ...
Numerous applications demand that we manipulate large sets of very high-dimensional signals. A simple yet common example is the problem of finding those signals in a database that are closest to a query. In this paper, we tackle this problem by restricting ...
This paper describes QEF a query evaluation framework designed to support complex applications on the grid. QEF has been extended to support querying within a number of different applications, including supporting scientific visualization and implementing ...
