  • Examples from each of these observatories: 1. Science Data Observatory: A. SemantEco B. SemantAqua
  • Examples from each of these observatories: 1. Open Government Observatory: A.Linked Open Government Data Portal B. International Open Government Dataset
  • Semantically-enabled environmental monitoring – in this case monitoring water quality. Done initially as a student project in McGuinness’ Semantic eScience class, attracted interest of USGS and has an extension done with USGS. Currently working on a cooperative agreement with USGS to continue. Also used as a model for semantically enabling monitoring of air, soil, food, etc. Project page:
  • Examples from each of these observatories: 1. Healthy & Life Sciences Observatory: A. HealthData Challenge
  • Examples from each of these observatories: 1. Social Spaces Data Observatory: A. Twitter Network Observatory B. First Responder Twitter Network
  • The RPI group has been developing Twitter Network Observatory to explore the relationships of people and semantics in the graph database. The basic functions have been fulfilled,including     Users could visualize and analyze different types of sub-graphs based on the selections of topic, time range.     The Twitter Network observatory performs a set of basic analyses for other COSMIC groups and users to support their purposes. We have been working on adding new functions including     The selection based on time range, location, and sentiments.     Network (and the topological properties) can be exported to various formats to be used in other software (GraphML, XGMML, SVG, etc.).
  • Introduction First Responders , including Emergency Medical Personnel, Firefighters, and Police Officers, have active online communities on Social Media websites. How can we leverage Social Media sites … to gather requirements for active First Responders? … to identify stakeholders within those First Responder communities? *
