Nowadays, thesauri are unavoidable bridges for semantic meshups between several domains. So they can be considered also as knowledge kernels of intelligent (environmental) information systems. Since information „lives” (changes quickly), the quality of involved thesauri and relaying information systems depends on their up-to-dateness. In this contribution we present a web service and sketch a m...

The use of Knowledge Organization Systems (KOSs) in aggregated metadata collections facilitates the implementation of search mechanisms operating on the same term or keyphrase space, thus preparing the ground for improved browsing, more accurate retrieval and better user profiling. Automatic thesaurus-based keyphrase extraction appears to be an inexpensive tool to obtain this information, but t...

In this short paper we present a scenario and requirements for ontology matching posed by a geographical application, namely a semantic geocatalog, which is an integral part of any spatial data infrastructure (SDI). It enables semantic interoperability among various geo-data and geo-service providers, and thus, contributes to the harmonization of geo-information. Introduction. The need for cohe...

Scientometric techniques have been remarkably successful at mapping science but they face important difficulties when mapping research for societal problems – possibly because they they are derived only from scientific documents and thus do not rely on non-academic expert knowledge. Here we aim to explore how ontologies can be used in science mapping, thus enriching current algorithmic techniqu...

Many different open information sources currently exist for protecting the environment in Europe, mainly focused on Natura 2000 network, and areas where environmental protection and activities like tourism need to be balanced. Managing these data and integrating them for supporting decision makers and for novel uses is a challenging task. The SmartOpenData project (2013-1015) aims to define mec...
