    • Capturing provenance of global change information 

      Ma, Xiaogang; Fox, Peter; Tilmes, Curt; Jacobs, Katharine; Waple, Anne (Nature Climate Change, 2014-05-29)
      Global change information demands access to data sources and well-documented provenance to provide the evidence needed to build confidence in scientific conclusions and decision making. A new generation of web technology, ...
    • Ontology Dynamics in a Data Life Cycle: Challenges and Recommendations from a Geoscience Perspective 

      Ma, Xiaogang; Fox, Peter; Rozell, Eric; West, Patrick; Zednik, Stephan (Journal of Earth Science, 2014-04-01)
      Ontologies are increasingly deployed as a computer-accessible representation of key semantics in various parts of a data life cycle and, thus, ontology dynamics may pose challenges to data management and re-use. By using ...
    • Ontology engineering in provenance enablement for the National Climate Assessment 

      Ma, Xiaogang; Zheng, Jin; Goldstein, Justin; Zednik, Stephan; Fu, Linyun; Duggan, Brian; Aulenbach, Steven; West, Patrick; Tilmes, Curt; Fox, Peter (Environmental Modelling and Software, 2014-08-28)
      The National Climate Assessment of the U.S. Global Change Research Program (USGCRP) analyzes and presents the impacts of climate change on the United States. The provenance information in the assessment is important because ...
    • Provenance Representation for the National Climate Assessment in the Global Change Information System 

      Tilmes, Curt; Fox, Peter; Ma, Xiaogang; McGuinness, Deborah; Privette, Ana; Smith, Aaron; Waple, Anne; Zednik, Stephan; Zheng, Jin (IEEE Transactions on Geoscience and Remote Sensing, 2013-07-12)
      The important topic of global climate change builds on a huge collection of scientific research. It is common for agencies releasing climate change information to be served with requests for all supporting materials resulting ...
    • Recent progress on geologic time ontologies and considerations for future works 

      Ma, Xiaogang; Fox, Peter (Earth Science Informatics, 2013-02-09)
      Semantic Web technologies bring innovative ideas to computer applications in geoscience. As an essential part of the Semantic Web, ontologies are increasingly discussed in the geoscience community, in which geologic time ...
    • Semantic Similarity Computation and Concept Mapping in Earth and Environmental Science 

      Zheng, Jin; Ma, Xiaogang; Fox, Peter (2013-12-04)
      Ontologies have been widely adopted and used by Earth and Environmental Science community to capture and represent knowledge in the domain. One of the major problems that prevent us to combine and reuse these ontologies ...
