Construction and evaluation of an oil spill semantic relation taxonomy


Published: Aug 26, 2016 by Knowledge Organization (International Journal)
Authors: Yejun Wu and Li Yang
Subjects: Environmental Science, Information Technology

The paper presents the rationale, significance, method and procedure of building a taxonomy of semantic relations in the oil spill domain for supporting knowledge discovery through inference. Difficult problems during the development of the taxonomy are discussed and partial solutions are proposed. A preliminary functional evaluation of the taxonomy for supporting knowledge discovery was performed.

Formative & summative evaluation of a large topic map as a ... learning tool


Published: Nov 26, 2015 by Knowledge Organization (International Journal)
Authors: Yejun Wu, Amanda Lehman, and David Dunaway
Subjects: Environmental Science, Information Technology

A large topic map was created to facilitate understanding of the impacts of the 2010 Gulf of Mexico Oil Spill Incident. A formative evaluation and two summative evaluations were conducted, as qualitative studies, to assess the usefulnessand usability of the large topic maps for facilitating self-regulated learning. The topic maps were found useful forknowledge fusion and discovery, and can be useful when undertaking interdisciplinary and multidisciplinary research.
