A Family History Knowledge Base in OWL 2

A Family History Knowledge Base Using OWL 2

A Solution for the Man-Man Problem in the Family History Knowledge Base

The Family History Knowledge Base (FHKB) was presented at OWLED in 2008. The FHKB uses a rich object property hierarchy, including many OWL 2 features, to derive many entailments on some 450 individuals representing the Stevens family. In the ABox, only parent relationships and some sibling relationships (either isSisterOf or isBrotherOf) are asserted. Using a sparse assertion of brother or sis...

Combining OWL with RCC for Spatioterminological Reasoning on Environmental Data

A new approach to spatioterminological reasoning is presented which is based on a hybrid knowledge representation system architecture and on a representation of the RCC family tree in OWL. The knowledge base into which the family tree is imported holds role assertions in terms of RCC-8 relations between individual regions. It is a key component of a semantic layer constructed on top of an envir...

On the Web Ontology Rule Language OWL 2 RL

It is known that the OWL 2 RL Web Ontology Language Profile has PTime data complexity and can be translated into Datalog. However, a knowledge base in OWL 2 RL may be unsatisfiable. The reason is that, when translated into Datalog, the result may consist of a Datalog program and a set of constraints in the form of negative clauses. In this paper we first identify a maximal fragment of OWL 2 RL ...

Use of OWL 2 to Facilitate a Biomedical Knowledge Base Extracted from the GENIA Corpus

The annotation of the GENIA corpus, a set of biomedical articles, targets the classification of biological entities based on their association with a domain-tailored taxonomy of categories. By incorporating information extraction process on the corpus we have developed a knowledge base (KB) that includes a more comprehensive taxonomy of categories, relationships between biological entities, and...
