TWed Talk: Weds, 17 Sep (7p, Winslow 1140) TITLE: "Capturing and Presenting Provenance of Global Change Research" Presenter: Xiaogang (Marshall) Ma LEADERS: Xiaogang (Marshall) Ma (Associate Research Scientist at Tetherless World Constellation, Rensselaer Polytechnic Institute)

Please join us TOMORROW, Weds, 17 Sep in Winslow as Marshall Ma leads us in what should be an interesting discussion on the importance of data provenance enablement in global change research and may ultimately play a role in policy and decision-making.

ABSTRACT: The topic of global change covers changes in the global environment that may alter the capacity of the Earth to sustain life and support human systems. The provenance information of global change research is important because the research findings are of great public and academic concern and are used in policy and decision-making. This talk consists of two parts. One is an introduction to the recent work on provenance enablement in information modeling and semantic prototypes for the Global Change Information System. Experience of ontology engineering with the use case-driven iterative approach developed by the Tetherless World Constellation will be presented. The other is a discussion on future works centered on the concept of scenario in global change research. A scenario is a qualitative or quantitative projection of the future. The talk will review the current works on scenario in global change research and set a context for further information modeling.

BIO: Short bio: Xiaogang (Marshall) Ma is an associate research scientist at Tetherless World Constellation, Rensselaer Polytechnic Institute. He received PhD of Earth Systems Science and GIScience from University of Twente, The Netherlands. His research interests include qualitative and quantitative modeling of complex systems in Earth and environmental sciences, data interoperability and provenance enablement through participatory approaches and semantic technologies, and exploratory visualization of spatio-temporal features in Big and Little Data.


==== TWed Logistics (Spring 2014):
  • TWed schedule
  • 7p-8p, 1st floor Winslow (1140)
  • We try to alternate TWed Talks with TWed Hackspaces. The alternating pattern of TWed Talks and TWed Hackspaces may "off" due to leader availability and Institute scheduling.
  • Pizza or snacks will be provided for TWed Talks
  • Live video streams of TWed Talks will usually be available via ustream
  • An archive of past TWed Talks are also available on ustream. Direct links can be found in the schedule (below)
  • TWed Talks from previous terms are archived; topical archive coming soon!
About TWed:
  • "TWed" is the Tetherless World Educational Series
  • "TWed Talks" are informal overview talks and tutorials on topics of interest to the Tetherless World community. TWed gives members of the lab the chance to share tools and expertise. TWed talks are not lectures; they are expected to be highly interactive and fun. TWed leaders are encouraged to include live "hack" activities in their session plans.
  • "TWed Hackspaces" during the TWed time are informal group work sessions inspired by the Hackerspace movement. This is a time when TWC people will "be around" and you can rely on the "right" people being available to answer your questions and help with your hacks. This is also a great opportunity for project teams to "hack" together on problems, with the knowledge and resources of TWC surrounding you.
