This paper describes articial neural networks which are based on the adaptiveresonance theory. The usage of these articial neural networks for classicationtasks is presented. The example uses is the classication of patient health fromthe results of general blood analysis.[...]

Expert-driven business process management is an establishedmeans for improving efficiency of organizational knowledge work.Implicit procedural knowledge in the organization is made explicit bydening processes. This approach is not applicable to individual knowledgework due to its high complexity...

We present the user-centered, iterative design of Mobile Facets, a mo-bile application for the faceted search and exploration of a large, multi-dimensional data set of social media on a touchscreen mobile phone. Mo-bile Facets provides retrieval of resources such as places, persons,...

One of the key factors that hinders integration of distributed, heterogeneousinformation systems is the lack of a formal basis for modeling the complex, structuredknowledge that is to be exchanged. To alleviate this situation, we present anapproach based on core ontologies. Core ontologies are...

Knowledge compilation is a common technique for propositionallogic knowledge bases. A given knowledge base is transformedinto a normal form, for which queries can be answered efficiently. Thisprecompilation step is expensive, but it only has to be performed once.We apply this technique to...

Ontologies play an important role in knowledge representationfor sharing information and collaboratively developing knowledgebases. They are changed, adapted and reused in different applicationsand domains resulting in multiple versions of an ontology. The comparisonof different versions and the...

With the Multimedia Metadata Ontology (M3O), we havedeveloped a sophisticated model for representing among others the annotation,decomposition, and provenance of multimedia metadata. Thegoal of the M3O is to integrate the existing metadata standards andmetadata formats rather than replacing...

Existing tools for generating application programming interfaces(APIs) for ontologies lack sophisticated support for mapping thelogics-based concepts of the ontology to an appropriate object-orientedimplementation of the API. Such a mapping has to overcome the fundamentaldierences between the...

The novel mobile application csxPOI (short for: collabora-tive, semantic, and context-aware points-of-interest) enables its usersto collaboratively create, share, and modify semantic points of interest(POI). Semantic POIs describe geographic places with explicit semanticproperties of a...
