چکیده

This paper analyzes the ontological requirements for representing biology knowledge, and identifies several areas where current knowledge representation (KR) paradigms need to be extended. We focus on the representation of experimental materials and methods, and the reasoning task of intelligent information retrieval; however, the ontological issues we raise apply to biology (and experimental sciences) in general. We have identified two important concept types in molecular biology that cause problems for standard knowledge models: 1) complex substances such as mixtures and nucleic acid sequences; 2) transformations (such as biochemical reactions) that convert one substances into another. We describe these problems, propose solutions for some of them, and given examples of the need for such knowledge representations in intelligent information retrieval.

Developing Ontological Theories for Conceptual Models using Qualitative Research

Conceptual modelling is believed to be at the core of the IS discipline. There have been attempts to develop theoretical foundations for conceptual models, in particular ontological models as axiomatic reference systems. Although the notion of ontology has become popular in modelling theories, criticism has risen as to its philosophical presuppositions. Taking on this criticism, we discuss the ...

Various forms of reasoning, the profusion of knowledge, the gap between neuro-inspired approaches and conceptual representations, the problem of inconsistent data input, and the manifold of computational paradigms for solutions of these problems challenge AI models for higher cognitive abilities. We propose the I-Cog architecture as a step towards a solution for these problems. I-Cog is a modul...

Ontological Foundations of Medical Information Systems

The modeling of knowledge and implementing it in software systems is not sufficiently supported by proper guidelines and well-established principles. An interdisciplinary approach seems to be necessary because the development of guidelines for ontologically sound knowledge modeling – in particular in medicine – requires knowledge and expertise from areas such as linguistics, informatics, medici...
