The karyotype ontology describes the human chromosome complement as determined cytogenetically, and is designed as an initial step toward the goal of replacing the current system which is based on semantically meaningful strings. This ontology uses a novel, semi-programmatic methodology based around the tawny library to construct many classes rapidly. Here,(More)
Developing ontologies can be expensive, time-consuming, as well as difficult to develop and maintain. This is especially true for more expressive and/or larger ontologies. Some ontologies are, however, relatively repetitive, reusing design patterns; building these with both generic and bespoke patterns should reduce duplication and increase regularity which(More)
Bio-medical ontologies can contain a large number of concepts. Often many of these concepts are very similar to each other, and similar or identical to concepts found in other bio-medical databases. This presents both a challenge and opportunity: maintaining many similar concepts is tedious and fastidious work, which could be substantially reduced if the(More)
Motivation: There are many challenges associated with ontology building, as the process often touches on many different subject areas; it needs knowledge of the problem domain, an understanding of the ontology formalism, software in use and, sometimes, an understanding of the philosophical background. In practice, it is very rare that an ontology can be(More)
There is still a lot of discussion about exactly what ontologies should represent, but what is generally agreed is that they formalise and relate to some relatively complex areas of knowledge. While ontology environments allow rich descriptions of the relationship between the entities inside the ontology (because this is what an ontology is), they often do(More)
