In application server systems, such as J2EE, replication is an essential strategy for reliability and efficiency. Many J2EE implementations, both commercial and open-source, provid...
Semantically heterogeneous and distributed data sources are quite common in several application domains such as bioinformatics and security informatics. In such a setting, each dat...
A new class of embedded devices is emerging that has a mixture of traditional firmware (written in C/C++) with an embedded virtual machine (e.g., Java). For these devices, the main...
The model of overloading views is a facility allowing the programmer to separate some kinds of crosscutting concerns that occur during design, implementation and maintenance of dat...
1 Although ontology has gained wide attention in the area of information systems, a criticism typical of the early days is still rehearsed here and there. Roughly, this criticism s...
Abstract. Clusters have become the de facto platform to scale J2EE application servers. Each tier of the server uses group communication to maintain consistency between replicated ...
Publish/subscribe middleware provides efficient support for loosely coupled communication in distributed systems. A number of different distributed message-filtering algorithms hav...
In this paper we present an implementation of a constraint solving module, CLP(Flex), for dealing with unification in an equality theory for terms with flexible arity function symb...
The use of domain-specific metadata (subject keywords) is tested for monolingual and bilingual retrieval on the GIRT social science collection. A new technique, Entry Vocabulary Mo...
This paper presents the approach used by the University of Alicante in the ImageCLEF 2004 adhoc retrieval task. This task is performed by multilingual search requests (topics) agai...
