Based on Anita de Waard’s work, we use a simple representation of ‘Epistemic Segment Types’. These consist of the following codes:
fact: a claim that has been accepted to be true, a known fact.
hypothesis: a proposed idea, not supported by evidence
problem: unresolved, contradictory, or unclear issue
goal: research goal
method: experimental method
result: a restatement of the outcome of an experiment
implication: an interpretation of the results, in light of earlier hypotheses and facts
other-goal: Goal described in a cited paper
other-implication: Interpretation made in a cited paper
other-problem: Problem described in a cited paper
other-fact: Fact with an explicit reference
other-hypothesis: Hypothesis presented in a cited paper
other-method: Method description in a cited paper
other-result: Experimental Result in a cited paper
BioScholar system is the web application I am building to house the framework for knowledge management and engineering based on the KEfEd / CoSI model. The
Digitial Libary is concerned with all aspects of managing papers and the
Fragmenter is simply the subcomponent within that that handles delineating fragments of text from within the overall body of the document. We have advanced this system significantly.
Figure 1 shows the latest version of the annotation system. This image shows the basic formulation of the Digital Library as a way of managing the full text documents of papers (PDFs, XMLs, HTMLs). It provides fragmenting capability over PDF files where each numbered fragment may be made up of several blocks, each fragment may also be assigned a
fragment type (based on the epistemic categories shown above).
Figure 2 shows the list of fragments.
Note that Figure 1 has a button labeled
brat. This permits the user to automatically dump the current fragments to an installation of the
brat annotation system for subsequent markup and processing (see Figure 3).
The Bioscholar system now has implemented an annotation framework that permits annotators to process texts according to these epistemics codes is shown at the following link:
