While semantic similarity plays a crucial role for human categorization and reasoning, computational similarity measures have also been applied to fields such as semantics-based information retrieval or ontology engineering. Several measures have been developed to compare concepts specified in various description logics. In most cases, these measures are(More)
The SIM-DL theory has been developed to enable similarity measurement between concept specifications using description logics. It thus closes the gap between similarity theories from psychology and formal representation languages from the AI community, such as the Web Ontology Language (OWL). In this paper, we present the results of a human participants(More)
As the Web moves towards structured data, new communication paradigms and user interfaces become necessary to support users beyond simple keyword search. In contrast to applications for expert users, these interfaces should hide the complexity of ontology-based systems but still offer their reasoning capabilities. Using Web gazetteers as application area,(More)
Auditory function and cochlear pathology were investigated in 4 minipigs subjected to compression to 4 ATA, held for 1 h, and decompressed using a standard schedule (Blackpool Tables) on 21 occasions. Three minipigs were used as controls. Brainstem auditory evoked response testing was carried out after the last hyperbaric exposure and showed no response(More)
Semantic similarity measurement gained attention as a methodology for ontology-based information retrieval within GIScience over the last years. Several theories explain how to determine the similarity between entities, concepts or spatial scenes, while concrete implementations and applications are still missing. In addition, most existing similarity(More)
While similarity has gained in importance in research about information retrieval on the (geospatial) semantic Web, information retrieval paradigms and their integration into existing spatial data infrastructures have not been examined in detail so far. In this paper, intensional and extensional paradigms for similarity-based information retrieval are(More)
In the last years, several methodologies for ontology engineering have been proposed. Most of these methodologies guide the engineer from a first paper draft to an implemented – mostly description logics-based – ontology. A quality assessment of how accurately the resulting ontology fits the initial conceptualization and intended application has not been(More)
Morphometric analysis was carried out on electron micrographs of motor endplates from three Jack Russell terriers affected with congenital myasthenia gravis (CMG) aged 10 weeks, 12 weeks and 22 weeks, respectively. Control endplates from age-matched pups and an adult Jack Russell were also examined. The results showed that postsynaptic membrane density was(More)
An account is given of a hypomyelinating condition, 'trembler', in the Bernese mountain dog. The condition is manifested clinically as a tremor of the limbs and head which becomes more intense with excitement or stress and which disappears with sleep. The tremor, which is first noticeable between two and eight weeks old, may persist throughout life but(More)
