ABSTRACT:
Session Topic: Meeting Big Data Challenges through Ontology - III

This is our 7th Ontology Summit, a joint initiative by NIST, Ontolog, NCOR, NCBO, IAOA & NCO_NITRD with the support of our co-sponsors. The theme adopted for this Ontology Summit is "Ontology for Big Systems." The event today is our 10th virtual session.

The principal goal of the summit is to bring together and foster collaboration among the ontology community, systems community, and stakeholders of some of "big systems." Together, the summit participants will exchange ideas on how ontological analysis and ontology engineering might make a difference, when applied in these "big systems. We will aim towards producing a series of recommendations describing how ontologies can create an impact; as well as providing illustrations where these techniques have been, or could be, applied in domains such as bioinformatics, electronic health records, intelligence, the smart electrical grid, manufacturing and supply chains, earth and environmental, e-science, cyberphysical systems and e-government. As is traditional with the Ontology Summit series, the results will be captured in the form of a communiqué, with expanded supporting material provided on the web.

The goal of "Meeting Big Data Challenges through Ontology" Track 3 is to identify issues that can be addressed using an ontology challenge. Challenges can take many forms and target many issues.

Potential issues to be addressed by challenges:


 * Enhance collaboration and accelerate agencies adoption
 * Accelerate the adoption of ontological methods, maximize public awareness, and impact of research.
 * Increase the number of agencies using ontologies, i.e., earlier adoption
 * Where should our focus be to accelerate agencies adoption of ontology capabilities?
 * How many scientists, physicists, engineers, programmers, big data administrators, etc. have experience with ontologies?
 * Is the growth of ontological implementations and technologies with Big Data constrained by the shortage of qualified personnel?
 * Inform, educate, and include the public in scientific research and discovery. Public involvement could be a critical component of our success
 * A mismatch between those with data and those with the skills to analyze the data
 * Are programmers able to optimize the use of unstructured or semi-structured data sets for scientists and engineers?
 * What are the talent and skill set issues impacting the use of ontologies?
 * The skills important to the growth of ontological technologies with Big Data include a combined understanding of a scientific or engineering discipline and knowledge of ontology-based technologies.
 * Programmers are not able to optimize the use of unstructured data for scientists and engineers
 * Scientists and engineers without ontology training may use brute force programming  this can be inefficient and the scientists and engineers without training may not be aware of options and capabilities using ontology-based technologies
 * Strategic significance to the economy, e.g. enabling competitive products.
 * How long does it take to become productive in the ontology environment?
 * Can universities expand coursework in ontologies and integrate ontological methods into the requirements for science degrees? At the undergraduate level? At the graduate level?
 * Identify individuals who have both domain experience and an understanding of what it means to apply ontology technologies.
 * Increase the number of individuals capable of applying ontology technology
 * Ontology-based technology evolution for big data may be slow or non-existent
 * Advances in the use of ontology technology can be difficult or unattainable without an adequate number of properly trained personnel, including scientists, engineers, programmers, system administrators, technologists, and all others that make up the big data systems.
 * Expanding the markets for ontologies could make the field a more attractive career path. What is the growth rate of the ontology market? Further expansion could spark investment and make ontologies an even more vibrant, attractive market for young people to enter.
 * A Challenge may seed and transform the current status quo
 * Software dilemma analogy with ontology
 * Ontologies and software perceived to be a commodity resulting in little or no investment in research. Projects use ontologies as one of their tasks

Potential challenge directions


 * 1. Increase the awareness of ontology technology among programmers/database managers
 * 2. Accelerate agencies adoption of ontology capabilities
 * 3. Enable scientists and engineers to make maximum use of big data
 * 4. Enable scientists and engineers to understand the potential of ontology-based systems integration
 * 5. Enable ontologists to understand scientists and engineers needs
 * 6. Ameliorate any mismatch between those with data and those with the skills to analyze it
 * 7. People in the domains of science, engineering, software, computer science, etc. can benefit from a combined knowledge of their domain and application of ontology-based technologies. A combined understanding of these domains and ontology-based technologies may encourage the growth of technology.
 * 8. Improve critical areas of current practice

This first session of Track 3 - ConferenceCall_2012_02_09 - was designed to help everyone understand the relationships between big data challenges and ontologies. At this second session today - ConferenceCall_2012_03_15 - we hope to talk about solutions and benefits. At the OntologySummit2012_Symposium, we would like to present various approaches to implementing ontologies using challenges and a sample from the NITRD Big Data working group.

Agenda
Ontology Summit 2012 - Panel Session-10


 * Session Format: this is a virtual session conducted over an augmented conference call

activities by providing a Web-based data representation that ties data to semantics models, facilitates data sharing and linking, supports provenance annotations, and can exploit a large and growing collection of background knowledge on the Web. While the concepts and technologies are mature and supported by sound standards, their use within most application communities remains relatively low. This presentation will touch on some current research aimed at reducing the barriers to wider adoption and use. It will describe techniques enabling end users to generate Semantic Web data using familiar software tools, and new approaches to querying large collections of Semantic Web data.
 * 1. Opening - co-chairs [15 min.] ... [ slides ]
 * 2. Panel briefings - - [15 min. each]
 * TimFinin - "Making the Semantic Web Easier to Use"
 * Abstract: Semantic Web technologies have the potential to support many
 * KyoungsookKim  "Use cases of cyber-physical data cloud computing (Tsunami application)"
 * Abstract: I will introduce a new application system based on cyber-physical data cloud for fusion and analysis of physical and social sensing data to facilitate real-world aware information services.
 * MikeFolk - "The HDF5 technology suite"
 * Abstract: HDF5 is a suite of technologies used widely in science and engineering for working with high volume, complex data. As such, HDF5 needs to support metadata as well as data. We will talk about how HDF5 can do this, and give an example.
 * MarioPaolucci - "FuturICT: Global Participatory Computing for Our Complex World"
 * for more information on FuturICT, see: brief brochure & full brochure on the FuturICT project
 * UrsulaKattner - "Data Needs for the Materials Genome Initiative (MGI) at NIST"
 * Abstract: The Materials Genome Initiative (MGI) seeks to enable U.S. companies to discover, develop, manufacture, and deploy advanced materials faster and more cost efficiently. A highly capable Materials Innovation Infrastructure (MII) will enable integrated computational materials engineering by providing a powerful, widely accessible toolkit with computational methods and management and dissemination of digital data.

BobSchloss: Peter, Leo et al: I am thinking about the April 12-13 F2F at NIST. I may not be able to be in Maryland by first thing in the morning on April 12th. Would you aim to put some details about start time, and agenda, on the page for the Symposium sometime in the next week. Thank you

BobSchloss: I do see that the page says that if you arrive at NIST at 8am, there will be time to get through security before things start. I just want to check that I could still arrive later and get through Security.... If there is one person I should talk to about such logistics, just give me their name, e-mail address, phone number. Thank you.

MaryBrady: Bob, you can most certainly arrive later at NIST and get through security. Arriving at 8:00 will just allow you to make it through prior to the start of the meeting.

MichaelGruninger: @BobSchloss: We will be putting an initial agenda up on the Symposium page sometime tomorrow

PeterYim: @BobSchloss - ref. person you can call - the official contact I have from the NIST registration page is at: http://ontolog.cim3.net/cgi-bin/wiki.pl?OntologySummit2012/WorkshopRegistration#nid36LP ... so feel free to call me on my mobile ( 650 578.9998 ) too

PeterYim: == Chairs doing intro ...

DougFoxvog: I've been unable to connect to Shared-screen support at http://vnc2.cim3.net:5800/. Is it up and running?

PeterYim: @Doug ... it should be - does anyone else have problems (especially if you have been able to do that before)

DougFoxvog: I was unable to connect with Firefox. But i managed to dredge up an Internet Explorer, and there was no problem. If anyone else is having a problem connecting with Firefox, i would suggest they try a different browser.

MarioPaolucci: I'm seeing the VNC but it took quite a while to establish connection

PeterYim: @Mario - don't worry about it (if you cannot get a "good" connection to the vnc server) just use your own slides (on your desktop) but please remember to call out slide advances and call out the slide numbers each time

PeterYim: == TimFinin presenting ...

DeborahMacPherson: Hi Everyone! Interesting discussion this all has been. I have several entire threads set aside to read again fully

SteveRay: @Tim Finin: Very cool. Is there a way to point your GOR tool to other SPARQL endpoints?

LeoObrst: @Tim: concerning Varish Mulwad's research (inferring semantics of tables), was Formal Concept Analysis considered?

TimFinin: @leo --- No, not to my knowledge. Good idea. We'll look into it and think about its value for this problem.

ErnieLucier: HTTP copies as hFp for all reference URLs in TimFinin's presentation. Replacing hPf with http works.

PeterYim: == KyoungsookKim presenting ...

KyoungsookKim: hi

MaryBrady: Dr. Kim, we are ready, *7 to un-mute

JosephTennis: This has been GREAT! Sorry I was late. And sadly, I'll have to leave early Looking forward to participating more in the near future!

PeterYim: @JosephTennis - Thank you for the participation, Joe

JosephTennis: ciao!

NicolaGuarino: Folks, unfortunately I have a car emergency, I have to leave. Perhaps I'll manage to connect again in 40 minutes or so, not sure. Sorry missing Mario's presentation.

PeterYim: @Nicola - thank you for the heads up ... bye!

ErnieLucier: Is permission to use social networks required?

HaroldBoley: @Dr. Kim, in Real-world Awareness Computing, could the Observation / Perception / (Communication) / Action sequence be formalized using Event / Condition / Action rules?

KyoungsookKim: currently, I try to use a rule-based language.

KyoungsookKim: like datalog

HaroldBoley: Maybe the premises of datalog rules need to be partitioned into Event and Condition parts?

HaroldBoley: Events are 'sensed' as external observations. Conditions 'test' the internal knowledge base.

PeterYim: == MikeFolk presenting ...

BobSchloss: Just an observation -- many people are working on highly scalable triplestores, some with interesting partitioning and distribution and federation functions. We might sometime convene a panel with all of these people showing what they did. It is not just graph stores that are advancing -- the entire NoSQL movement is starting to develop various interesting strategies, in which some of the classic ACID properties are slightly relaxed.

AliHashemi: The pdf version of this presentation is not rendering appropriately for me. Is it just me?

KyoungsookKim: me too

AliHashemi: @Kyoungsook - I downloaded the file and opened it in Reader - it works ok there, I think my browser's pdf reader doesn't show it correctly.

KyoungsookKim: thank you.

AmandaVizedom: @MikeFolk - HDF5 is new to me, so I find I have some "what *is* HDF5?" questions below the level of your talk. I see that at http://www.hdfgroup.org/HDF5/, there are links for "What is HDF5?" "Questions (FAQ)," and "HDF5 Tutorial" links. Would you recommend these as the best source for an overview of the fundamentals of HDF5?

DavidOrloff: Sorry need to run to a meeting - if anyone is looking for data to work with that is already tagged with ontologies (9 in use) look at http://www.cellimagelibrary.org and contact me DavidOrloff at dorloff[at]ascb.org - thanks for letting me sit in - I will be back for future calls.

PeterYim: == MarioPaolucci presenting ...

PeterYim: @MarioPaolucci - how does the project mitigate between its desire to be "open" versus it's dependencies (ref. your slides) on commercial products (like skype, facebook, etc. ... which are usually non-open)

MarioPaolucci: @PeterYim: There are several strategies possible. We plan to build alternative data sources and provide access to them. We will not depend on commercial platforms (the names in the slide were there more as an examples of changes brought about by technology), but we hope to create our own data sharing platform, where user themselves authorize access to their data. In a sense, we hope to convince people to reclaim access to their data.

MarioPaolucci: @PeterYim: We think users would be happier to share data with a privacy preserving, non profit project, but it's a risky bet, I agree.

PeterYim: @Mario - thank you ... but then, the challenge comes in the form of how (and if at all) one can build out a user base of hundreds of millions of people (like the success some of these commercial social network platforms have achieved)

HaroldBoley: @MarioPaolucci, what would be the initial steps for moving from a Strongly Coupled System to a Weakly Coupled System?

MarioPaolucci: @Harold: I can only provide stylized examples; it depends from the specific problem. But of course you can hardly intervene on the self-organization, so what can be done is changing the terrain where things happen. The examples that come to my mind is the roundabout instead of the intersection; or in a sand pile model, breaking up the table so that cascades remain limited.

HaroldBoley: @Mario, You could 'overlay' the roundabout -- with 4 quarter-circle 'bypasses' -- over the intersection, so at least to help those not in the center of the congestion.

MarioPaolucci: @Harold:Exactly. Also, adding new dimensions help - either by digging a tunnel, or - better - providing car with vertical mobility. Think if this as a metaphor - new dimensions are easier to create in virtual worlds, of course

MarioPaolucci: oops. I forgot to put the links.

MarioPaolucci: list of supporters: http://www.futurict.eu/the-project/whos-involved

PeterYim: == UrsulaKattner presenting ...

UrsulaKattner: The link for the Materials Genome Initiative is http://www.whitehouse.gov/blog/2011/06/24/materials-genome-initiative-renaissance-american-manufactu ring

DeborahMacPherson: Interested in discussing the differences between calculated and measured values referred to by the speaker just now

UrsulaKattner: @DeborahMacPherson: Measured values have a confidence resulting from the error of the measurement, calculated values have no such error. However, a confidence for these data is needed to properly judge them in the context of data that describe a material.

DeborahMacPherson: Need to sign off - thanks to all the speakers -

PeterYim: == EdinMuharemagic presenting ...

DougFoxvog: I think we're on slide 3

PeterYim: @Mary - please ask the speaker to call out the slide advance AND slide number

MaryBrady: Please, if you have questions, post them here...we'll be sure to engage the speakers in answering the questions over e-mail

MatthewHettinger: @Edin, What open source products are you using?

PeterYim: == MaryBrady (co-chair) moderating open discussion

MaryBrady: In particular a number of technologies and use cases for BIG DATA have been presented this afternoon. Any thoughts on potential uses for Ontology?

MarioPaolucci: @Mary: We have ontology components in all parts of the FuturICT architecture, of course. Nicola Guarino knows more about them. But we have a critical need of ontologies that allows the different components to communicate - think of aligning models and simulation results along disciplines (sociology, complex science) and along levels of detail (individual agents, organizations, groups, etc.) There should be a world of modeling component in which ontology is very important.

FrankOlken: @PeterYim Will all of the Ontology Summit sessions be webcast? I am thinking of attending remotely ...

PeterYim: @FrankOlken - are you referring to the OntologySummit2012_Symposium (at NIST on 4/12 & 13)?

PeterYim: @Frank - ... assuming that, the answer is "yes" - remote participation will be supported for all the sessions

FrankOlken: @PeterYim Yes, I am referring to the Ontology Summit on April 12-13 at NIST. I am already committed to a trip the previous week (Data Engineering conf) and am reluctant to commute to DC twice in 2 weeks.

SteveRay: @Frank: We may have a problem using Skype when we are at NIST, because they ban Skype there for security reasons.

PeterYim: @Steve, @Frank - we will be hosting calls in a way (and with the same tools) similar to all Ontolog virtual session ... except that we may not support shared-screen (vnc), but then, that has never been a show stopper for us

FrankOlken: @PeterYim I think that your infrastructure for supporting the teleconferences has worked quite well. I use skype to listen.

anonymous morphed into NicolaGuarino

MarioPaolucci: @Nicola: bentornato!

MaryBrady: Any thoughts on the integration of ontology components with output from machine learning techniques?

FrankOlken: @MaryBrady I recall that some folks have suggest using ontologies to suggest concepts to be learned.

MaryBrady: @FrankOlken Yes, here at NIST we have used combination techniques between ontologies and machine learning. Simple queries can sometimes take days to complete.

FrankOlken: Nearly every machine learning algorithm is available under R.

FrankOlken: There are versions of R that run on clouds with Hadoop.

FrankOlken: There is recent work at IBM and Univ. of Wisconsin on parallel implementation of stochastic gradient descent for machine learning.

LeoObrst: Must go now. Very interesting session. Thanks to all!

DougFoxvog: @Mario You discuss using "Crowd sourcing" and "citizen science" for a platform for economic and political participation. People on different sides of various issues would have competing "science". How would you deal with this?

NicolaGuarino: @Doug: here is exactly one of the roles of ontologies in this project: exposing disagreements about different opinions...

NicolaGuarino: @Doug: the point is *understanding* the different models, not necessarily forcing them to align one each other

DougFoxvog: @Nicola So long as the different theories/models are kept separate, i strongly agree. The problem i saw was with an "open" system which would allow people to modify theories that they didn't create.

NicolaGuarino: @Doug: You are right. Definitely people shouldn't be allowed to modify things at their ease... especially if the underlying assumptions are not shared...

MarioPaolucci: Thank you everybody for listening and for the questions. I have to leave now, bye!

PeterYim: @KyoungsookKim - how effectively did the systems cited in your use cases turn out (in real life) ... were there metrics available?

AmandaVizedom: Dr. Kim, someone responded to my G+ posting about your presentation by mentioning evacuation response research such as some at Univ. of Minnesota ( http://gradworks.umi.com/32/05/3205248.html, http://www.spatial.cs.umn.edu/paper_ps/evac_SSTD05.pdf). My response is that this sort of research, in itself valuable, would relate to your use case as a contribution to *one* of the areas of computation involved in the response. It seems to me that what makes your use case such a Grand Challenge type case is that it brings together a variety of such areas, including route-planning and information fusion across very heterogenous sensor and information types and disaster surveillance over networks. Do you agree?

AmandaVizedom: @KyoungsookKim - I should add that I think it's really a very good Grand Challenge, for a few reasons, including that it is so well grounded in a real need *and* real, existing data environments, and success has such clear benefits.

ErnieLucier: @Dr. Kim, Is permission to use social networks required or a problem?

KyoungsookKim: using social network, we don't try to use personal information itself. We aggregate a group of messages and extract trend information or changing information.

SteveRay: Must run. Thanks for a stimulating session.

PeterYim: wonderful session ... great presentations!
