In this paper we present an application fostering the integration and interoperability of computational lexicons, focusing on the particular case of mutual linking and cross-lingual enrichment of two wordnets, the ItalWordNet and Sinica BOW lexicons. This is intended as a case-study investigating

semi-automatic generation of bilingual lexicons through linking of distributed monolingual lexical resources. In addition to lexicon development, the architecture also allows enrichment of monolingual source lexicons through exploitation of the semantic information encoded in corresponding entries

for the large-scale semantic enrichment of a computational linguistic resource. To this end, with the aid of a controlled vocabulary, we identified a set of representative concepts, i.e. a restricted, but meaningful number of concepts from WordNet, such that each of them can replace any of its descendants

work with a language that lacks a wordnet, the question is not whether, but how and how fast to construct such a lexical resource. The construction is costly, with the bulk of the cost due to the high linguistic workload. This appears to have been the case, in particular, in two multinational

Abstract. Semantic sensor networks use declarative descriptions of sen-sors promote reuse and integration, and to help solve the difficulties of installing, querying and maintaining complex, heterogeneous sensor net-works. This paper reviews the state of the art for the semantic specifi-cation of sensors, one of the fundamental technologies in the semantic sensor network vision. Twelve sensor ontologies are reviewed and anal-ysed for the range and expressive power of their concepts. The reasoning and search technology developed in conjunction with these ontologies is also reviewed, as is technology for annotating OGC standards with links to ontologies. Sensor concepts that cannot be expressed accurately by current sensor ontologies are also discussed. 1

First, I would like to thank to Dimka Karastoyanova and Mariano Cilia for all the fruitful discussions, their guidance and support through the course of this project. Thanks also to Prof. Alejandro Buchmann who sponsored my stay at Technische Universität Darmstadt during the spring of 2004. The special thanks go to my advisor, Mariano Cilia, who has made all this possible. Finally, I’d like to thank to my family for all these years of support.

by applying a path-expression language like XPath (W3C 1999a) to the two data schemas, providing for semi-automatic generation of the databinding modules, but at deployment time, not query time. The network-facing components are implemented as SOAP services using the Apache Axis framework (Apache 2005a
