Bio-ontologies and information visualisation have arisen in recent years as means to assist biologists in making sense of this information. Ontologies can enable the construction of conceptual queries, but existing systems to do this are too technical for most biologists. OntoDas, the software developed as part of this thesis work, demonstrates how the application of techniques from information visualisation and human computer interaction can result in software which enables biologists to construct conceptual queries.enComputer software--Development.Ontology.Expert systems (Computer science)Molecular biology.Knowledge representation (Information theory)Conceptual structures (Information theory)Database design.Theses--Computer science.Thesis
