Title: Challenges for Knowledge Management in BHomedical
Informatics
Abstract: Although some data structure choices in biological
computing are relatively straightforward (using strings for DNA and protein
sequence, and using cartesian three-dimensional coordinates for molecular
structure), things get much more complicated when one tries to represent
biological functional information. Biological function is often
described hierarchically, and is only "known" based on what is
observable, not necessarily what one would like to observe. This
creates challenges and gaps that must be met with clever data structures designed
to support complex reasoning tasks. In the coming decades, I believe
that more complex representations of biological knowledge will be required,
and there will be a renaissance of interest in knowledge structures--data
structures that can hold complex cognitive concepts--in order to support in
silico biology. These knowledge structures will bridge the field to
high fidelity mathematical models of biological processes, and will continue
to be useful as cognitively useful summaries of these mathematical models. Russ
