Abstract

Experiences in Knowledge Sharing: Lessons from research and experience in Big Data, Linked Data and Semantic Web Applications ... intro slides

This is our 9th Ontology Summit, a joint initiative by Ontolog, NIST, NCOR, NCBO, IAOA & NCO_NITRD with the support of our co-sponsors.

Since the beginnings of the Semantic Web, ontologies have played key roles in the design and deployment of new semantic technologies. Yet over the years, the level of collaboration between the Semantic Web and Applied Ontology communities has been much less than expected. Within Big Data applications, ontologies appear to have had little impact.

This year's Ontology Summit is an opportunity for building bridges between the Semantic Web, Linked Data, Big Data, and Applied Ontology communities. On the one hand, the Semantic Web, Linked Data, and Big Data communities can bring a wide array of real problems (such as performance and scalability challenges and the variety problem in Big Data) and technologies (automated reasoning tools) that can make use of ontologies. On the other hand, the Applied Ontology community can bring a large body of common reusable content (ontologies) and ontological analysis techniques. Identifying and overcoming ontology engineering bottlenecks is critical for all communities.

Ontology Summit 2014 will pose and address the primary challenges in these areas of interaction among the different communities. The Summit activities will bring together insights and methods from these different communities, synthesize new insights, and disseminate knowledge across field boundaries.

In this session we aim to bring together the lessons learned to date and new insights on the re-use of ontology content. We have three speakers lined up to share their perspectives on ontology re-use in the contexts of knowledge representation and sharing, linked data and semantic web reasoning applications. These presentations will be followed by an open discussion on the considerations and requirements for those wanting to identify and use semantic resources in each of these contexts, and the things to think about when developing ontologies for re-usability.

Briefings

  • Dr. John F. Sowa (VivoMind Intelligence) - "Historical Perspectives: On Problems of Knowledge Sharing" ... slides
    • Abstract: Documents and libraries written and read by humans have been highly successful for the past three millennia. But differences in languages have been a major obstacle for knowledge sharing among humans. Computer systems are much faster than humans, but much less flexible, tolerant, and knowledgeable. This talk will investigate how we can simplify and enhance knowledge sharing among computers and humans.
  • Professor MichelDumontier (Stanford BMIR) - "Tactical Formalization of Linked Open Data" ... slides
    • Abstract: I will discuss the current challenge of working with "schema-lite" LOD, various strategies to make sense of this data (mappings/community standards), and how we formalize specific parts (in OWL) so they are fit for purpose (deductive reasoning in conjunction with data mining).
  • Mr. KingsleyIdehen (OpenLink Software) - "Ontology Driven Data Integration & Big Linked Open Data" ... slides
    • Abstract: I will discuss how ontologies are being used to address heterogeneous data virtualization. In particular, we will cover: how data across heterogeneous data sources is reconciled using entity relations described in shared ontologies, i.e., what you increasingly find on the Linked Open Data (LOD) and Linked Open Vocabulary (LOV) clouds.

Session Topic: Experiences in Knowledge Sharing: Lessons from research and experience in Big Data, Linked Data and Semantic Web Applications

Session Co-chairs:

PROGRAM:

  • Dr. John F. Sowa (VivoMind Intelligence) - "Historical Perspectives: On Problems of Knowledge Sharing"

  • Mr. Kingsley Idehen (OpenLink Software) - "Ontology Driven Data Integration & Big Linked Open Data"

Logistics:

  • (if you haven't already done so) please click on "settings" (top center) and morph from "anonymous" to your RealName; also please enable "Show timestamps" while there.
  • Mute control (phone keypad): *7 to un-mute ... *6 to mute
    • you may connect to (the skypeID) "joinconference" whether or not it indicates that it is online

(i.e. even if it says it is "offline," you should still be able to connect to it.)

    • if you are using skype and the connection to "joinconference" is not holding up, try using (your favorite POTS or

VoIP line, etc.) either your phone, skype-out or google-voice and call the US dial-in number: +1 (206) 402-0100

... when prompted enter Conference ID: 141184#

    • Can't find Skype Dial pad?
      • for Windows Skype users: Can't find Skype Dial pad? ... it's under the "Call" dropdown menu as "Show Dial pad"
      • for Linux Skype users: if the dialpad button is not shown in the call window you need to press the "d" hotkey to enable it
  • when posting in this Chat-room, kindly observe the following ...
    • whenever a name is used, please use the full WikiWord name format (every time you don't, some volunteer will have to make an edit afterwards)
    • always provide context (like: "[ref. JaneDoe's slide#12], I think the point about context is great" ... rather than "that's great!"

as the latter would mean very little in the archives.)

    • when responding to a specific individual's earlier remarks, please cite his/her full WikiWord names *and*

the timestamp (in PST) of his/her post that you are responding to (e.g. "@JaneDoe [11:09] - I agree, but, ...")

[9:52] Matthew West: What counts as "small set of semantic content" and what counts as "large set of

semantic content" on Slide 6 of the introduction?

[9:55] Andrea Westerinen: @MatthewWest [9:52] "Small" means a design pattern with a few classes and

relationships. "Large" could be a complete domain or upper ontology or schema.

[9:56] Simon Spero: @MatthewWest [9:52] : small == can be visualized on an A0 poster : large = (not small)?

[9:52] GaryBergCross: Welcome John....

[10:01] GaryBergCross: Lack of Semantic app software not well integrated with mainstream IT is a

major problem as shown on slide 5.

[10:03] Anne Thessen: I completely agree with John F. Sowa slide 6 ["We need better tools, interfaces,

and methodologies ..."]

[10:04] GaryBergCross: This is a topic for the Tool track to address.

[10:13] Peter P. Yim: ... on slide#16 now

[10:13] Amanda Vizedom: Question for @JohnSowa (we are on slide 11, but q applies to this whole range

of slides): In my experience, being familiar with the history of logic & these fundamentals is

useful in making ontology design/architecture decisions, in recognizing the logical equivalence (or

non-) of different representation approaches, and in recognizing certain ontology anti-patterns that

correspond to classic logical errors. However, they are no where near enough to ground reusable

ontology development. How do you think that understanding these logical representations and patterns

is helpful to overcoming obstacles to reuse?

[10:16] Alex Shkotin: @AmandaVizedom, we should not repeat their errors;-)

[10:19] GaryBergCross: @AmandaVizedom Great question for John. I hope we get to it in discussion.

[10:19] Peter P. Yim: ... on slide#22 now

[10:20] Alex Shkotin / Mike Bennett: ... slide 24

[10:20] GaryBergCross: John is getting at problems of reusing some well know resources like WordNet.

[10:21] Peter P. Yim: ... on slide#28 now [10:21] GaryBergCross: [ ref. slide#29: "Enable subject-matter

experts to review, update, and extend their knowledge bases with little or no assistance from IT

specialists" ] Uh oh.. getting rid of the KE means unemployment for some of us...

[10:22] Cory Casanave: Many (most?) domain experts have no notation, what is the notation of law enforcement?

[10:22] Simon Spero: @CoryCasanave: UCR (Uniform Crime Reporting)

[10:23] Simon Spero: @CoryCasanave: 10-codes

[10:24] Cory Casanave: @Simon, they do have domain vocabularies - but most lack ways to express them

other than text and spreadsheets

[10:26] Mike Bennett: @CoryCasanave [10:22] if you walk into any conference room there are whiteboard

diagrams with boxes and lines. So presenting subject matter in edges and lines, with textual

annotation, should be a relatively universal SME format.

[10:30] Cory Casanave: @MikeBennett, some people respond to ad-hoc boxes and lines, some don't. Fewer

respond to boxes and lines with any semantic consistency [10:31] Mike Bennett: @CoryCasanave very

true - in any group there are those whose primary modality is visual, and those whose is verbal.

Need spreadsheets / tables / wiki pages for the latter. THe same content needs to be expressable in

both.

[10:36] John F. Sowa: @MikeBennett, I strongly support spreadsheets. That's another example of a

modality that requires almost zero learning to start using effectively.

[10:38] Mike Bennett: @JohnSowa I've seen some very complex SME spreadsheets - but it's their

complexity not ours. I think there's potential in a spreadsheet structure that reflects classes,

properties (with real-world names on the columns, not OWL terms)

[10:41] John F. Sowa: @MikeBennett (and continuation of note to @DennisWisnosky), then I would derive as

much of the knowledge as possible from available data of any kind -- structured and unstructured.

The primary role of the SME would be to answer questions to help the automated tools work better.

[10:24] Dennis Wisnosky: Why documents feeding the NL Tools. Why not some SIRI?

[10:30] John F. Sowa: @DennisWisnosky, I mentioned documents because the bulk of the knowledge is in

documents. But I would certainly recommend SIRI or similar voice-based tools as an option --

especially for hands-free use by the SMEs.

[10:24] Amanda Vizedom: About @JohnSowa's slide 20: I would (do, have done) argue that the quest for

a complete ontology has been an significant hindrance to the development of reusable ontologies.

Even if it were a complete ontology, to incorporate all of the contextual variation and dependencies

observed in reality, it would be unusable. It would be at least as unusable as a life-sized map.

Ontologies, like scientific models, need to be circumscribed in order to be usable. But that doesn't

mean we can't have reuse. IMHO, it does mean we have to do better at making the boundaries and

emphasis of our ontologies clear and detectable.

[10:27] John F. Sowa: @Amanda, short answer: what we can learn from history is the requirement that

tools must be designed for the SMEs to use without additional training. We still need KEs, but not

in the middle between the SME and the system. There is much more to say, but that's another topic.

[10:30] Todd Schneider: @JohnSowa, in your assertion that 'systems have been inter-operating for ...'

many years leaves out the process to get them to inter-operate. The ability to get information (and

other) systems to inter-operate in a timely and cost effective manner is still a challenge.

[10:34] John F. Sowa: @ToddSchneider, I agree. Semantics has helped us develop better systems. But more

people would use more and better semantics if the learning curve were less steep.

[10:40] Todd Schneider: @JohnSowa, I agree. If engineers had more training in logic and ontological

analysis would help in this regard. However, somethings are difficult to understand (e.g., Saharon

Shelah's book on Classification Theory, Quantum Field Theory). Of course this puts the onus on us to

help create tools that aid the general user to better apply the techniques of ontology when creating

information.

[10:35] Dennis Wisnosky: @JohnSowa - you don't discuss the bias of the SME's and the bias of the

Knowledge person to bias the KB = ontology. I believe that just as in other domains - e.g.

manufacturing the only way truth will will-out is to eliminate the human.

[10:38] John F. Sowa: Dennis, I didn't even have time to mention all my slides. If by "eliminating the

human" you mean that as much as possible of the knowledge be derived from available resources (Big

Data),

[10:43] Dennis Wisnosky: @JohnSowa - Yes, just saw your last sting and I agree. In addition, first I

am buying totally that a NL processor takes the place of the knowledge worker = the ontologist,

maybe. Secondly, I am saying that over time we can build rules into the NL processor that based upon

the natural laws that you mentioned, as well as the context, etc. throws away that which does not

make sense. This may happen in real time, or analyzing what the data store as it is amassed.

[10:46] Andrea Westerinen: @DennisWisnosky [10:43] NL processing really only works if it understands

the language of the domain of the SME. This is not generic. At this point in time, getting the

domain concepts right could be partially automated but definitely needs cleanup and iteration by

SMEs.

[10:47] John F. Sowa: I am not advocating full NL understanding. But current tools can derive enough

from documents (or speech) to formulate intelligent questions when they need help.

[10:48] Andrea Westerinen: @JohnSowa [10:47] That has not been my experience - unless you have

knowledge of the domain and its language.

[10:48] John F. Sowa: @AndreaWesterinen For examples of the way systems can learn by reading, see

http://www.jfsowa.com/talks/goal7.pdf [10:45] John F. Sowa: @ToddSchneider and @DennisWisnosky, I

believe that highly trained experts already know the best way to talk about their field. They should

not have to learn any conventions that we want them to use.

[11:08] Todd Schneider: @JohnSowa, "highly trained experts already know the best way to talk about

their field", but only within their field. If there's a need to communicate outside their field

(i.e. inter-operate), then there's a problem. [11:17] John F. Sowa: @ToddSchneider, I agree that many

experts don't communicate effectively with people in other fields. But the problem for anybody,

expert or not, to communicate effectively with computers is many orders of magnitude more difficult.

[11:16] GaryBergCross: @JohnSowa would you have an issues with the value of formalizing small

schemas the way Michel did for the relation between drug disease pathway and gene?

[10:23] Peter P. Yim: == Michel Dumontier presenting ...

[10:31] Amanda Vizedom: @MichelDumontier, very glad to have presentation that starts from deep

awareness of how much is out there (as in LOV) and moves through experiences with trying to reuse

it. Thanks for contributing this.

[10:50] Michel Dumontier: @AmandaVizedom thanks for your comment :)

[10:54] Amanda Vizedom: @MichelDumontier, You're welcome. Many are confronting such tactical issues

now, I think. Folks increasingly start with a plan to reuse, but find it nowhere near as simple as

they expected. Gory details of how people manage reuse successfully are valuable!

[10:42] Amanda Vizedom: Something going unstated here wrt this discussion of tools for KE / ontology

development and the question of reusable content / reuse of content. I'm not saying that they are

unrelated, only that the conversation just above (multiple participants) seems to be taking as

obvious what the connection is. Are any of you willing & able to spell that out?

[10:48] GaryBergCross: @MichelDumontier Very nice perspective on a tactical approach to

formalization for specific reuse.

[10:51] Michel Dumontier: @Gary Thanks!

[10:49] Peter P. Yim: @MichelDumontier - for what you are trying to achieve, does limitations of

expressivity of the ontology language (OWL in your case) come into the picture

[10:52] Michel Dumontier: @PeterYim so far we have been quite happy with OWL for consistency checking

(OWL-DL profile) and query answering (OWL-EL profile)

[10:54] Michel Dumontier: @PeterYim As we look towards more *accurate* representations of source

knowledge, however, may require something else

[10:55] Peter P. Yim: @MichelDumontier, thanks ... what are the "something else" being considered now?

[10:57] Peter P. Yim: Thank you, @MichelDumontier

[10:57] Michel Dumontier: @PeterYim probabilistic reasoning (from aggregation and evidence type),

non-monotonic reasoning (for inconsistent kbs)

[10:55] GaryBergCross: @MichelDumontier Is the OntoFunc Tool something that might be easily used by

interested parties for finding relations between object and ontology categories in areas other than

Biomedicine?

[10:57] Michel Dumontier: @GaryBergCross yes. can be used with any terminology.

https://code.google.com/p/ontofunc/

[10:56] Robert Powers: @MichelDumontier Could category theory/ologs be an answer to the problem of

representation you show in slide 11?

[11:01] Michel Dumontier: @RobertPowers two factors - initial RDF was minimal (model 1) because

triple stores didn't scale, and different datasets do not necessarily collect all the data that

another similar type dataset does. we need a general model for entity-attribute-value pertaining to

measurements to define standard representations. e.g.

https://code.google.com/p/semanticscience/wiki/ODPMeasurements and

http://www.jbiomedsem.com/content/5/1/14/abstract

[11:04] Robert Powers: @MichelDumontier Yes, thx Michel!

[11:03] Simon Spero: @MichelDumontier OASIS Quantities and Units of Measure Ontology Standard

(QUOMOS) TC https://www.oasis-open.org/committees/tc_home.php?wg_abbrev=quomos

[11:06] Andrea Westerinen: @MichelDumontier There is also Quantities, Units, Dimensions and Data

[10:57] Peter P. Yim: ... on slide#7 now

[11:00] GaryBergCross: @KingsleyIdehen Thanks for framing this practical issue of the dilemma for

LOD folks finding a starting point.

[11:02] GaryBergCross: @KingsleyIdehen Some of us start not with a formal ontology or LOD vocabulary

but with a "conceptual model" of the domain under consideration.

[11:04] Matthew West: ... Apologies, I have to leave.

[11:05] Peter P. Yim: ... bye, Matthew West

[11:06] Kingsley Idehen: http://kidehen.blogspot.com/2014/02/class-equivalence-based-reasoning.html

[11:07] Terry Longstreth: @KingsleyIdehen thesis reminds me of a Turing award lecture by Ken Iverson

"Notation as a tool of thought", where he argued that the result of a mental process is invfluenced

by the medium and means used. Computer Science also went through a period when the most important

buzzword was 'design language' which was distinct from but mappable to an implementation method.

[11:15] Andrea Westerinen: @TerryLongstreth [11:07] This also is covered in Gerald Weinberg's

Introduction to General Systems Thinking" - in his Laws of Difference and Indifference.

[11:09] Mike Bennett: @TerryLongstreth that sounds like the Saphir-Whorff hypothesis in spoken

language.

[11:20] Terry Longstreth: @MikeBennett - you're probably right, but I think what Iverson was really

talking about was how he used APL as a logical notation beyond programming.

[11:14] Amanda Vizedom: @KingsleyIdehen - slides 12-13 are a great example of how some reasoning *is*

a key part of making Linked Data effective. Granted, subsumption reasoning is the least disputed,

but it gives a nice, salient example of how even small increments of reasoning and

ontology/vocabulary mapping greatly amplify the power of linked data.

[11:17] Andrea Westerinen: @KingsleyIdehen, slide 17 - separating the rules from the concepts, and

allowing individual reuse of both, is one of the "summary" points from the Track A emails. Thanks!

[11:18] Kingsley Idehen: @SimonSpero: no [11:19] Kingsley Idehen: @SimonSpero: it has to be

:ClassX owl:equivalentClass :ClassY as the basis for such inference

[11:18] Peter P. Yim: @KingsleyIdehen, great talk ... btw, I think the url's on your (pdf version) slide

deck are not active ... can you supply an updated version, so I can swap in, please

[11:26] Kingsley Idehen: [re. AmandaVizedom's verbal question] I don't mind answering this question

[11:33] Mike Bennett: The problem with Facebook "Like" is that it doesn't really mean "Like" (re

Kingsley's description of FB Like in LOD)

[11:34] Simon Spero: http://attempto.ifi.uzh.ch/acewiki/

[11:35] Simon Spero: [a data wiki type tool]

[11:35] Terry Longstreth: I think Facebook's ubiquity has meant the new meaning of Like is now

authoritative, particularly for non-English speakers

[11:35] Simon Spero: [in ref to @KingsleyIdehen's points]

[11:35] Kingsley Idehen: Tooling

[11:33] Mike Bennett: ... @Peter are we Ok to continue another 5 mins?

[11:35] Peter P. Yim: ... @MikeBennett, sure, by all mean (we started about 10 min. late)

[11:37] Mike Bennett: ... Thanks @Peter. We'll aim to wrap up at nn:40

[11:37] Peter P. Yim: ... great, Mike!

[11:38] ... anonymous morphed into Sunday Ojo

[11:39] Amanda Vizedom: +1 for have a context in which, "when we want to make some information

contribution, we can see what the impact of that would be" (--@MichelDumontier) and to having

something like the Linked Data Wiki that @KingsleyIdehen described, so we can see what exists and

how things are connected, at a granular (not whole ontology) level. [11:39] Kingsley Idehen: The

likes relation describe via OpenCyc, but part of the LOD cloud: http://bit.ly/YgLgtk

[11:39] Simon Spero: Data citation support is an important need for research scientists

[11:40] Simon Spero: so they can get tenure XP

[11:40] Michel Dumontier: Force11 - http://www.force11.org/datacitation

[11:49] Simon Spero: @MichelDumontier force11 efforts were the ones I was thinking of; the details

are a work in progress, but they are making progress

[11:40] Kingsley Idehen: http://lod.openlinksw.com/c/G34LSH7 -- OpenCyc Likes & Dislikes

[11:41] Mike Bennett: Facebook "Like" means "I wish to follow this conversation" and has no

commonality with sentiment
