This paper will address the context-sensitive knowledge representation problem of ontology. The author regards the notion of context as a set of dimensions. The approach of applying dimensions to ontology is presented as a framework named Dimensional Ontology (DO). After analyzing different approaches for ontology contextualization, the author explores deeply the concepts and semantics of dimensions...
NeXML is a data format for evolutionary informatics that allows for semantic annotation with RDF triples, thereby providing unparalleled flexibility and extensibility of evolutionary data on the Semantic Web. BioRuby is a fastgrowing toolkit for bioinformatics currently lacking NeXML I/O, and, more generally, an API for triples. In this paper, we design the Ruby API of a NeXML parser and writer for...
Tupelo is a data and metadata management system based on semantic web technologies. Data are in the form of blobs, while metadata are represented as RDF triples. But some data are translated from other blobs. For example, arbitrary data described by DFDL can be translated into XML or further into RDF. This paper presents a plugin of Tupelo for managing data translation (e.g. how to control translation...
This paper presents an ontology based knowledge modeling approach for Chinese Genealogical Record (CGR). Ontology (RDF/OWL) is introduced to modeling static knowledge of CGR, while Ontology Molecule is intended to solve dynamic and multi-granular knowledge modeling problem. Ontology inference and ontology visualization technologies are adopted for more effective and efficient knowledge mining and...
