Annotation Paper Submitted to HPCS 2007 Event

I’ve blogged and presented recently (locally and at an international scientific event) on the topic of annotation and knowledge representation.

Working with co-authors Jerusha Lederman, Jim Freemantle and Keith Aldridge, a written version of the recent AGU presentation has been prepared and submitted to the HPCS 2007 event. The abstract is as follows:

Semantically Enabling the Global Geodynamics Project:
Incorporating Feature-Based Annotations via XML Pointer Language (XPointer)

Earth Science Markup Language (ESML) is efficient and effective in representing scientific data in an XML-based formalism. However, features of the data being represented are not accounted for in ESML. Such features might derive from events, identifications, or some other source. In order to account for features in an ESML context, they are considered from the perspective of annotation. Although it is possible to extend ESML to incorporate feature-based annotations internally, there are complicating factors identified that apply to ESML and most XML dialects. Rather than pursue the ESML-extension approach, an external representation for feature-based annotations via XML Pointer Language (XPointer) is developed. In previous work, it has been shown that it is possible to extract relationships from ESML-based representations, and capture the results in the Resource Description Format (RDF). Application of this same requirement to XPointer-based annotations of ESML representations results in a revised semantic framework for the Global Geodynamics Project (GGP).

Once the paper is accepted, I’ll make a pre-submission version available online.

Because the AGU session I participated in has also issued a call for papers, I’ll be extending the HPCS 2007 submission in various interesting ways.

And finally, thoughts are starting to gel on how annotations may be worked into the emerging notions I’ve been having on knowledge-based heuristics.

Stay tuned.
