چکیده

The Semantic Web is build around a semi-structured data model RDF and an explicit conceptualization for such data so-called ontologies. A standardized language for the specification of the latter has recently be proposed by the W3C. This paper explores the strategies for the implementation of this language in logic programming environments such as Prolog and relational databases. Along these lines we establish the subset of OWL primitives that is compatible for further rule-based extensions paving the way to the upper levels of the Semantic Web layer cake. We also capture a subset, for which query languages can easily be implemented by compiling expressions given in a declarative query language to the query language offered by the system on top of which the implementation is based.

An Executive Approach Based On the Production of Fuzzy Ontology Using the Semantic Web Rule Language Method (SWRL)

Today, the need to deal with ambiguous information in semantic web languages is increasing. Ontology is an important part of the W3C standards for the semantic web, used to define a conceptual standard vocabulary for the exchange of data between systems, the provision of reusable databases, and the facilitation of collaboration across multiple systems. However, classical ontology is not enough ...

Brightness variability in the white badge of the eagle owl Bubo bubo

The application of modern spectrometry to the study of avian colour variability has revealed ignored patterns of colour variation such as male-biased sexual dichromatism and seasonal variability in the plumage. However, the variation in the achromatic property of such traits, that is in the total light reflectance of the spectrum (i.e., brightness), has commonly been overlooked. The evolution o...

Vocal behaviour and neighbour spatial arrangement during vocal displays in eagle owls (Bubo bubo)

We quantified temporal and spatial patterns of adult eagle owl Bubo bubo vocal behaviour throughout an entire year. The duration of adult eagle owl vocal displays showed significant differences during different periods of the year: there was one major peak in the pre-laying period, when duets of mates were also more frequent. The daily distribution of adult vocalizations showed a similar patter...

Great horned owl (Bubo virginianus) dietary exposure to PCDD/DF in the Tittabawassee River floodplain in Midland, Michigan, USA.

Soils and sediments in the floodplain of the Tittabawassee River downstream of Midland, Michigan, USA contain elevated concentrations of polychlorinated dibenzofurans (PCDF) and polychlorinated dibenzo-p-dioxins (PCDD). As a long-lived, resident top predator, the great horned owl (Bubo virginianus; GHO) has the potential to be exposed to bioaccumulative compounds such as PCDD/DF. Site-specific ...
