Overview of Semantic Integration - Thu 2016-02-25     (1)

Abstract     (1B)

  • Context: A general belief that there is a convergence on standards for interoperability components, including catalogs, vocabularies, services and information models. The application of ontologies to provide semantics for this interoperability has been an active area of research in several disciplines including the GeoSciences where it now plays a central role in tackling the problems of semantic heterogeneity.     (1B1)
  • Perception: In an era of Big Data and Big Science diverse GeoScience data are increasingly being collected across many domain areas and wide spatial scales.     (1B2)
    • Increasingly interdisciplinary work requires some way of efficiently handling system, service and data heterogeneity. Valid and formal semantics is perceived to be a way of addressing these challenges.     (1B2A)
    • The GeoSciences are broadly defined to include not only the Earth Sciences but also geographically distributed sensor networks, such as air traffic control and power grids.     (1B2B)
  • Motivation: Report on activities such as NSF’s EarthCube that feature different GeoScience domains working on semantic interoperability issues to promote understanding of the state of the art across different approaches and what challenges remain:     (1B3)
    • What are the ranges of GeoScience ontologies used across the domain?     (1B3A)
    • How have ontologies been enhanced and expanded for use and reuse?     (1B3B)
    • What issues of knowledge building and reuse have been noted?     (1B3C)
    • What new standards might be     (1B3D)

Agenda     (1C)

  • Dial-in:     (1D4)
    • Phone (US): +1 (425) 440-5100 ... (long distance cost may apply)     (1D4A)
    • Skype: join.conference (i.e. make a skype call to the contact with skypeID="join.conference") ... (generally free-of-charge, when connecting from your computer ... ref.)     (1D4B)
      • when prompted enter Conference ID: 843758#     (1D4B1)
      • Unfamiliar with how to do this on Skype? ...     (1D4B2)
        • Add the contact "join.conference" to your skype contact list first. To participate in the teleconference, make a skype call to "join.conference", then open the dial pad (see platform-specific instructions below) and enter the Conference ID: 843758# when prompted.     (1D4B2A)
      • Can't find Skype Dial pad? ...     (1D4B3)
        • for Windows Skype users: Can't find Skype Dial pad? ... it's under the "Call" dropdown menu as "Show Dial pad"     (1D4B3A)
        • for Linux Skype users: please note that the dial-pad is only available on v4.1 (or later; or on the earlier Skype versions 2.x,) if the dialpad button is not shown in the call window you need to press the "d" hotkey to enable it. ... (ref.)     (1D4B3B)
    • instructions: once you got access to the page, click on the "settings" button, and identify yourself (by modifying the Name field from "anonymous" to your real name, like "JaneDoe").     (1D5A)
    • You can indicate that you want to ask a question verbally by clicking on the "hand" button, and wait for the moderator to call on you; or, type and send your question into the chat window at the bottom of the screen.     (1D5B)
    • thanks to the soaphub.org folks, one can now use a jabber/xmpp client (e.g. gtalk) to join this chatroom. Just add the room as a buddy - (in our case here) summit_20160225@soaphub.org ... Handy for mobile devices!     (1D5C)
  • Discussions and Q & A:     (1D6)
    • Nominally, when a presentation is in progress, the moderator will mute everyone, except for the speaker.     (1D6A)
    • To un-mute, press "*7" ... To mute, press "*6" (please mute your phone, especially if you are in a noisy surrounding, or if you are introducing noise, echoes, etc. into the conference line.)     (1D6B)
    • we will usually save all questions and discussions till after all presentations are through. You are encouraged to jot down questions onto the chat-area in the mean time (that way, they get documented; and you might even get some answers in the interim, through the chat.)     (1D6C)
    • During the Q&A / discussion segment (when everyone is muted), If you want to speak or have questions or remarks to make, please raise your hand (virtually) by clicking on the "hand button" (lower right) on the chat session page. You may speak when acknowledged by the session moderator (again, press "*7" on your phone to un-mute). Test your voice and introduce yourself first before proceeding with your remarks, please. (Please remember to click on the "hand button" again (to lower your hand) and press "*6" on your phone to mute yourself after you are done speaking.)     (1D6D)
  • RSVP to gruninger@mie.utoronto.ca with your affiliation appreciated, ... or simply just by adding yourself to the "Expected Attendee" list below (if you are a member of the community already.)     (1D8)
  • Please note that this session may be recorded, and if so, the audio archive is expected to be made available as open content, along with the proceedings of the call to our community membership and the public at-large under our prevailing open IPR policy.     (1D10)
