An automated reasoning framework for translational research
AbstractIn this paper we propose a novel approach to the design and implementation of knowledge-based decision support systems for translational research, specifically tailored to the analysis and interpretation of data from high-throughput experiments. Our approach is based on a general epistemological model of the scientific discovery process that provides a well-founded framework for integrating experimental data with preexisting knowledge and with automated inference tools.In order to demonstrate the usefulness and power of the proposed framework, we present its application to Genome-Wide Association Studies, and we use it to reproduce a portion of the initial analysis performed on the well-known WTCCC dataset. Finally, we describe a computational system we are developing, aimed at assisting translational research. The system, based on the proposed model, will be able to automatically plan and perform knowledge discovery steps, to keep track of the inferences performed, and to explain the obtained results
WHAT IS INFORMATION SUCH THAT THERE CAN BE INFORMATION SYSTEMS?
Information systems, as a discipline, is concerned with the generation, storage and transmission of
information, generally by technological means. As such, it would seem to be fundamental that it has
a clear and agreed conceptualization of its core subject matter – namely “information”. Yet, we
would claim, this is clearly not the case. As McKinney and Yoos point out, in a recent survey of the
term information within information systems: “This is the IS predicament – using information as a
ubiquitous label whose meaning is almost never specified. Virtually all the extant IS literature fails to
explicitly specify meaning for the very label that identifies it.” We live in an information age and the
vast majority of information (whatever it may be) is made available through a wide range of
computer systems and one would expect therefore that information systems would in fact be one of
the leading disciplines of the times rather than one that appears to hide itself in the shadows.
Governments nowadays routinely utilize many academic experts to advise them in a whole range of
areas but how many IS professors ever get asked? So, the primary purpose of this paper is to
stimulate a debate within IS to discuss, and try to establish, a secure foundation for the discipline in
terms of its fundamental concept – information. The structure of the paper is that we will firstly
review the theories of information used (generally implicitly) within IS. Then we will widen the
picture to consider the range of theories available more broadly within other disciplines. We will
then suggest a particular approach that we consider most fruitful and discuss some of the major
contentious issues. We will illustrate the theories with examples from IS
