This project focused on foundational research into the creation of a transformational, dynamic environment for pedagogy, knowledge construction, discourse, collaboration, and research in the domain of Geographic Information Science and Technology (GIS&T).
Central to the project was a transformation of the GIS&T BoK into a core ontology for the field (BoKOnto). The project built a computational system that exposes this ontology to various end user applications via web services. The BoKWiki application allows exploration and editing of the GIS&T BoK.
The BoKVis Visualization tool provides access to GIS&T BoK 1 through:
(a) visual browsing of the original hierarchical structure, using several different methods
(b) visualization of text queries with respect to BoK content, using a choice of text similarity techniques
Earlier iterations of the software also included:
(c) visualization of BoK ScoreCards
(d) direct comparison of two queries or two ScoreCards
A BoKScore expresses the weight or degree of the relationship between an entity and a particular BoK concept. A BoKScoreCard is a mapping between entities and seferal BoK concepts.
Entities could be persons, courses, documents, etc., for example:
- a person: which concepts in the BoK is he or she proficient in (to one degree or another)?
- a course: which concepts in the BoK are being taught (to one degree or another)?
The goal of the BoKWiki application is to provide a web-based interface for revising the GIS&T Body of Knowledge in a manner that encourages involvement by a substantial cross-section of the geospatial community. This semantic wiki application includes editorial functionality to ensure that the results are authoritative and reliable.
The Persistent Virtual Environment (PVE) element of this project targeted an immersive multi-user virtual environment (MUVE) based on the Jibe platform to allow users to interact with the BoK both individually and in groups.
A kiosk lists the ten BoK knowledge areas, and each of these areas is a separate panel that allows the user to teleport to a specific environment dedicated to that knowledge area. When teleported, they are greeted by intelligent agents (AI – based robots) that will answer questions and guide their inquiry process.
