OntologySummit2015 Track A Session - Thu 2015-03-12     (1)

Topic: : Ontology Integration in the Internet of Things (IoT) [Track A session-2]     (1A)

Session Co-chairs: RamSriram & LeoObrst     (1B)

Billions of things will be connected to the Internet. These things span a spectrum of cognitive abilities from simple sensors to humans. Ontologies will play a significant role in integrating these things at different abstraction levels. The goal of track A (Ontology Integration in the Internet of Things) is: To discuss the various approaches being taken to address the integration and interoperability issues. We intend to present case studies of IoT, discuss current approaches in integration and interoperability, discuss gaps in current approaches, and discuss issues of vertical integration and interoperability across layers of the IoT, including granularity. We also want to propose methods for achieving integration and interoperability through ontologies, and propose a unified framework for integration and interoperability for multimodal (audio, text, video, etc.) interfaces.     (1C1)

Agenda     (1D)

  • RamSriram (NIST): Toward Internet of Everything: Internet of Things (IoT), Cyber Physical Systems (CPS), and Smart Networked Systems and Societies (SNSS)     (1D2)
    • Abstract: The Internet of Everything (IoE) or Smart Networked Systems and Societies (SNSS) will have significant implications for both the market for advanced computing and communication infrastructure and the future markets ­ for nearly 4.5 billion people -- that net-centric societies will create. I will start my presentation with a brief discussion on the evolution of SNSS. The development of a trusted, secure, reliable, and interoperable net-centric computing environment will need technologies that can assure a flexible and scalable system allowing the application of diverse and robust privacy requirements, thus enabling the trusted and meaningful growth of net-centric infrastructures for the benefit of all societies. I will discuss the research challenges (in information technology) for achieving the above net-centric computing environment.     (1D2A)
  • SpencerBreiner (NIST) and EswaranSubrahmanian (Carnegie Mellon University, NIST): Category Theory for Modular Design: An IoT Example     (1D3)
    • Abstract: Category theory (CT) is the mathematical study of structure and, as such, provides a rich formal language for the specification and analysis of ontologies, broadly construed as structured representations of information. In this talk we will use constructions from CT to define a formal model for a smart heating system in a house. Although simplistic, the model highlights various advantages of the category theoretic approach including modularity, extensibility, rich semantics and deep connections with the theory of databases and programming languages. As an integrative formalism, Category theoretical models could also serve in the requirements definition of IoT components and as a substrate for learning algorithms using the data base to evolve the underlying behavioral models of the components.     (1D3A)
  • KrzysztofJanowicz (University of California, Santa Barbara): Ontology Virtualization For Smart Environments     (1D4)
    • Abstract: The Internet of Things is more than just connected devices. It is about the interaction of cyber-systems with the physical environment, individuals, and society. In such a heterogeneous setting where multi-thematic, multi-perspective, multi-media data have to be handled at different spatial, temporal, and thematic granularities, semantic interoperability becomes a key challenge. While ontologies and Semantic Web technologies have been proposed to address data integration and interoperability, monolithic ontologies do not perform well in highly heterogeneous settings. Ontology design patterns have been proposed to handle this issue by providing modular but self-contained building blocks. Additionally, new research shows promise in approaching the knowledge engineering bottleneck by means of ontology learning. While both approaches aim at scaling ontology engineering, it is also worth exploring how to scale the (re)use of ontologies. In this talk we introduce the notion of ontology virtualization, namely to abstracts from the underlying patterns and axiomatization to provide flexible plug&play-style reconfiguration of patterns together with purpose-driven 'semantic views'.     (1D4A)

Additional Resources     (1H)

  • Dial-in:     (1I3)
    • Phone (US): +1 (425) 440-5100 ... (long distance cost may apply)     (1I3A)
    • 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.)     (1I3B)
      • when prompted enter Conference ID: 843758#     (1I3B1)
      • Unfamiliar with how to do this on Skype? ...     (1I3B2)
        • 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.     (1I3B2A)
      • Can't find Skype Dial pad? ...     (1I3B3)
        • for Windows Skype users: Can't find Skype Dial pad? ... it's under the "Call" dropdown menu as "Show Dial pad"     (1I3B3A)
        • 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.)     (1I3B3B)
    • 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").     (1I4A)
    • 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.     (1I4B)
    • thanks to the 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) ... Handy for mobile devices!     (1I4C)
  • Discussions and Q & A:     (1I5)
    • Nominally, when a presentation is in progress, the moderator will mute everyone, except for the speaker.     (1I5A)
    • 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.)     (1I5B)
    • 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.)     (1I5C)
    • 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.)     (1I5D)
