Abstract     (1I)

OntologySummit2013 Session-13: Ontology Summit 2013 Communique: First Draft Review - intro slides     (1I1)

This is our 8th 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 Evaluation Across the Ontology Lifecycle."     (1I2)

Currently, there is no agreed methodology for development of ontologies, and there are no universally agreed metrics for ontology evaluation. At the same time, everybody agrees that there are a lot of badly engineered ontologies out there, thus people use -- at least implicitly -- some criteria for the evaluation of ontologies.     (1I3)

During this Ontology Summit, we seek to identify best practices for ontology development and evaluation. We will consider the entire lifecycle of an ontology -- from requirements gathering and analysis, through to design and implementation. In this endeavor, the Summit will seek collaboration with the software engineering and knowledge acquisition communities. Research in these fields has led to several mature models for the software lifecycle and the design of knowledge-based systems, and we expect that fruitful interaction among all participants will lead to a consensus for a methodology within ontological engineering. Following earlier Ontology Summit practice, the synthesized results of this season's discourse will be published as a Communique.     (1I4)

In this 13th virtual panel session of the Summit, the co-lead editors will present their plans for the communique and an initial draft, and discuss that with the community. They will go through the document by sections, present them, and then ask for comments.     (1I5)

[9:29] anonymous morphed into Clare Paul     (1K2AI)

[9:31] Peter P. Yim: == Fabian Neuhaus starts the session on behalf of the session co-chairs ... see: [     (1K2AJ)

0-Chair ] slides     (1K2AK)

[9:34] anonymous morphed into Francesca Quattri     (1K2AL)

[9:36] Steve Ray: My suggestion for a 5th high-level question for the bottom of page 1 on the     (1K2AQ)

communique: We should include something that covers intrinsic evaluation, such as: -Is the ontology     (1K2AR)

free of obvious inconsistencies and errors in modeling?     (1K2AS)

[9:39] Amanda Vizedom: Slide 6 - schedule -- is off. Next week, April 18, is the 2nd draft review.     (1K2AT)

Final draft will be complete by May 1.     (1K2AU)

[9:42] Todd Schneider: Change 'IT' to 'information'.     (1K2AV)

[9:43] Peter P. Yim: +1 re Todd Schneider suggestion above     (1K2AW)

[9:44] anonymous morphed into Shari Thurow     (1K2AX)

[9:45] Amanda Vizedom: Fabian notes: We are going to have some terminology clashes. We will need to     (1K2AY)

discuss what are the best terms to use for some items; we can then do a global search & replace.     (1K2AZ)

[9:46] Todd Schneider: Amanda, who is the intended audience? That should drive terminology issues.     (1K2AAA)

[9:46] Matthew West: On Quality. Some of what we are doing here is rediscovering things that have     (1K2AAB)

been well established over some 50 years in other areas. It is useful for us to use other language     (1K2AAC)

when we are discovering that we are doing the same thing as others have done before, but once we     (1K2AAD)

have understood it is the same thing, we should adopt the language that is established and try to     (1K2AAE)

learn from their experience rather than re-invent it. I would hope we had reached that point during     (1K2AAF)

this summit.     (1K2AAG)

[9:52] Simon Spero: @MatthewWest: Are any of the definition sections of ISO 9K/9K1 available in the     (1K2AAH)

public domain?     (1K2AAI)

[10:05] Matthew West: @Simon how about this for quality related definitions:     (1K2AAK)

http://www.praxiom.com/iso-definition.htm these look pretty good to me. You will noticed that we     (1K2AAL)

have independently identified the need for many of these things.     (1K2AAM)

[9:51] Amanda Vizedom: @Matthew, I agree. We discussed this, but I failed to come up with a     (1K2AAN)

satisfactory alternative. So, we decided instead to put this question, of what terminology to use     (1K2AAO)

where we have "model quality". Suggestions?     (1K2AAP)

[9:55] Matthew West: @Amanda I'm quite happy to review the document and make specific suggestions so     (1K2AAQ)

that the text is consistent with standard quality management terminology if that would be helpful.     (1K2AAR)

However, there is a wider point. I take the adoption of the language we use as an indicator of the     (1K2AAS)

communities maturity in this area. So if the community is not yet comfortable with quality     (1K2AAT)

terminology, then it is better to note this as an issue, than adopt the language when it does not     (1K2AAU)

reflect where the community is.     (1K2AAV)

[9:56] Todd Schneider: The term 'quality' should be banished from the communique (sorry Matthew, but     (1K2AAW)

use of this term does [not] help).     (1K2AAX)

[10:09] Matthew West: @Todd Interestingly when you talk about quality management, you tend not to use     (1K2AAY)

the term quality very much, beyond the name of the process, mostly you talk about meeting     (1K2AAZ)

requirements.     (1K2AAAA)

[9:48] Shari Thurow: If this helps, my Information Architecture Institute colleague came up with an     (1K2AAAB)

[9:57] Todd Schneider: Amanda, if ontology development is so similar to software, why not state it.     (1K2AAAD)

[10:04] Amanda Vizedom: Todd, we do.     (1K2AAAE)

[9:49] Todd Schneider: The diagram in the Lifecycle Overview section should be better aligned to more     (1K2AAAF)

common systems engineering 'stages' (e.g., the SE V).     (1K2AAAG)

[9:51] Steve Ray: @Todd: I think I agree with you. Or at least we should make reference to the     (1K2AAAH)

classic SE phases.     (1K2AAAI)

[10:00] Todd Schneider: Have to go. I'll be sending 'suggestions'.     (1K2AAAJ)

[9:58] Joanne Luciano: jumping in with a comment (i have not been following - so it this is off or     (1K2AAAK)

redundant just ignore): in the interim (at least) in the Exec summary -- What is the purpose of this     (1K2AAAL)

document would be useful (esp since it is for a wider audience)     (1K2AAAM)

[10:00] Joanne Luciano: RE: life cycle....figure -- the figure doesn't depict a "cycle" shouldn't it?     (1K2AAAN)

[10:02] Joanne Luciano: If not, then maybe developmental stage or some other analogy would be better     (1K2AAAO)

[10:02] Fabian Neuhaus: @Joanne: true. I always thought that lifecycle is a misnomer     (1K2AAAP)

[10:06] Terry Longstreth: @Joanne - +1.. The cycle should show feedback from operational experience     (1K2AAAQ)

to requirements changes and resulting ontology changes     (1K2AAAR)

[10:09] Peter P. Yim: the ontolology lifecycle diagram seems a bit incomplete, I suggest looking at the     (1K2AAAS)

7 ontology lifecycle phases from Mike Denny as used in the Ontology Summit 2013 Survey of software     (1K2AAAT)

capabilities:     (1K2AAAU)

Exploration Phase Management Phase Design Phase Build Phase General Development Concept Development     (1K2AAAV)

Relationship Development Validation Phase Integration & Use Phase Maintenance Phase     (1K2AAAW)

[10:26] Peter P. Yim: @Amanda & Fabian - my issue is with the diagram only ... I can see that you guys     (1K2AAAX)

have covered that well in the "Model Build Phase" writeup     (1K2AAAY)

[10:10] Shari Thurow: Where is user/usability testing in this list?     (1K2AAAZ)

[10:20] Peter P. Yim: Further to the above [10:09] MikeDenny's seven ontology lifecycle phases, even     (1K2AAAAA)

that set is missing the phases where one implements - formalizes and reduces the design into a     (1K2AAAAB)

representation in an ontology language. I think that should be added into the diagram two ... and     (1K2AAAAC)

presumably, there are very specific ontology evaluation needs at that phase of the lifecycle     (1K2AAAAD)

[10:17] Simon Spero: @PeterYim: This presupposes the older forms of software engineering. In more     (1K2AAAAE)

recent approaches, testing and integration occurs at all times, even during requirements gathering,     (1K2AAAAF)

(which is iterative)     (1K2AAAAG)

[10:22] Peter P. Yim: @SimonSpero - totally agree ... of course MikeDenny's focus was on software     (1K2AAAAJ)

tools/environments (and so he was light on the non-tools related work ... and probably just group     (1K2AAAAK)

them under the "design phase")     (1K2AAAAL)

[10:25] Fabian Neuhaus: @Peter: is there a document where the phases listed above are explained?     (1K2AAAAM)

[10:30] Peter P. Yim: @FabianNeuhaus [10:25] - see what got captured at the "Ontology of Ontology     (1K2AAAAN)

Evaluation" Hackathon HC-05 - (p.11~15) of     (1K2AAAAO)

luation/wip/HC-05_doc-snapshot_at-end-day-20130331/2013-03-30RequirementsGatheringWorkingFile_201303     (1K2AAAAQ)

31_at-end-day2.rtf     (1K2AAAAR)

[10:28] Terry Longstreth: on Denny's lifecycle - I recommend Integration and Use be two phases     (1K2AAAAS)

(Delivery/Deployment and Operational Use) From the latter we should show (repair and new     (1K2AAAAT)

requirements requests) going into Maintenance, and a from there (change actions) splitting into     (1K2AAAAU)

separate lines to management, design, and build.     (1K2AAAAV)

[10:31] Simon Spero: @TerryLongstreth: Is Integration necessarily a separate phase or is that just a     (1K2AAAAW)

feature of some lifecycle     (1K2AAAAX)

[10:39] Terry Longstreth: @Simon [10:31] - That's why I re-labeled it Delivery/deployment. In     (1K2AAAAY)

general, Final integration is essentially packaging up the product for deployment. It's assumed to     (1K2AAAAZ)

include a final factory integration test.     (1K2AAAAAA)

[10:39] Amanda Vizedom: NB: these steps need not be separate in time or cleanly separated. In fact,     (1K2AAAAAB)

they will often overlap and blur together. Ontological Analysis and Modelling (informal or formal)     (1K2AAAAAC)

may support each other and happen together. But they are conceptually separate and have different     (1K2AAAAAD)

requirements.     (1K2AAAAAE)

[10:11] Amanda Vizedom: We are open to suggestions for specific areas in which existing software     (1K2AAAAAF)

evaluation methods handle some aspect of the ontology evaluation without need for ontology-specific     (1K2AAAAAG)

modification. If they can so be applied as-is, we should say that. If they can be so applied in     (1K2AAAAAH)

principal, but the tools do not exist to do this for ontologies, that is an important point to make     (1K2AAAAAI)

in our future/recommendations section.     (1K2AAAAAJ)

[10:12] Joanne Luciano: @Peter - I was just about to paste in the same thing! would someone point me     (1K2AAAAAK)

to where the **purpose** of the communicate is stated -- i.e. beyond a summary of the presentations     (1K2AAAAAL)

[10:12] Joanne Luciano: Can we put "who the audience is" in the exec summary?     (1K2AAAAAN)

[10:13] Peter P. Yim: @Joanne - check out Fabian & Amanda's opening slides for today -     (1K2AAAAAO)

ft-review/OntologySummit2013_Communique_first-draft-review--FabianNeuhaus-AmandaVizedom_20130411.pdf     (1K2AAAAAQ)

... that's what they are intending to do (this year)     (1K2AAAAAR)

[10:13] Joanne Luciano: Thanks (i had to join late)     (1K2AAAAAS)

[10:14] Joanne Luciano: + agree with amanda - eval isnt being used when it could be.     (1K2AAAAAT)

[10:15] Steve Ray: Good responses, Amanda & Fabian. Let's state clearly up front who we are talking     (1K2AAAAAU)

to, such as Amanda's observation of "people who are building ontologies but are not evaluating     (1K2AAAAAV)

[10:13] Matthew West: It's not just about building a good one, but building one reliably, and not be     (1K2AAAAAX)

surprised by the results.     (1K2AAAAAY)

[10:15] Fabian Neuhaus: @ Matthew: yes, I agree. I meant "good" in the sense of high quality, where     (1K2AAAAAZ)

quality encompasses all of the characteristics (intelligibility, well-designed model, fitness to     (1K2AAAAAAA)

operational requirements)     (1K2AAAAAAB)

[10:34] Ali Hashemi: @Fabian, @Steve - doesn't it depend on how you've implemented your ontology     (1K2AAAAAAC)

development processes?     (1K2AAAAAAD)

[10:15] Terry Longstreth: + with amanda and Joanne, but much of today's discussion is from the     (1K2AAAAAAF)

perspective of an ontologist evaluating their own work. Can we throw a bone to those who want to     (1K2AAAAAAG)

evaluate an ontology as a 'found' object?     (1K2AAAAAAH)

[10:17] Shari Thurow: I agree with Terry.     (1K2AAAAAAI)

[10:32] Amanda Vizedom: Terry, we agree that the reuser is important and needs to be discussed and     (1K2AAAAAAJ)

supported. We indicate in some places that this is meant to be included, but I think that you are     (1K2AAAAAAK)

pointing out that we need to make this clearer. The idea is that the exploration-ontological     (1K2AAAAAAL)

analysis - design phases need to be carried out to *some* degree in order for the ontology consumer     (1K2AAAAAAM)

to be able to tell, even roughly, whether an existing model might suit there needs.     (1K2AAAAAAN)

[10:34] anonymous morphed into Lamar Henderson     (1K2AAAAAAO)

[10:35] Simon Spero: Steve Ray describes a modeling mistake of something being made A subclass that is     (1K2AAAAAAP)

really a property; can you clarify this?     (1K2AAAAAAQ)

[10:36] Simon Spero: ok.... that's pretty wrong...     (1K2AAAAAAR)

[10:37] Joanne Luciano: Great question by Steve Ray -- when does this get caught (very common) -     (1K2AAAAAAV)

Shipping method is_a "Book"     (1K2AAAAAAW)

[10:38] Joanne Luciano: The Manchester paper on Common errors and pitfalls is well-worth a read     (1K2AAAAAAX)

(before implementation) -- but good point     (1K2AAAAAAY)

[10:40] Steve Ray: @Joanne: +1. Perhaps our communique could at least provide some pointers to     (1K2AAAAAAZ)

resources that are a good start, such as the paper you mention.     (1K2AAAAAAAA)

[10:37] Mike Bennett: Isn't there a related issue here, that there is ontology with a small o -     (1K2AAAAAAAB)

capturing the domain knowledge formally, in which some fundamental errors need to be caught as per     (1K2AAAAAAAC)

Steve's example, and then there's Ontology with a bigO in OWL or CLIF as a technical artifact. These     (1K2AAAAAAAD)

may happen at the same time, but there may also be development lifecycles in which the ontology is     (1K2AAAAAAAE)

the formal capture of domain knowledge for some implementation technology other than reasoning     (1K2AAAAAAAF)

applications.     (1K2AAAAAAAG)

[10:38] Mike Bennett: So the kinds of error that relate to meaning itself would be captured at     (1K2AAAAAAAH)

potentially a different stage to the trapping of errors in DL-safe reasoning requirements or other     (1K2AAAAAAAI)

ontology application requirements. Semantics v syntax essentially.     (1K2AAAAAAAJ)

[10:37] anonymous1 morphed into Pavithra Kenjige     (1K2AAAAAAAK)

[10:37] anonymous morphed into Nancy Wiegand     (1K2AAAAAAAL)

[10:39] anonymous morphed into Torsten Hahmann     (1K2AAAAAAAM)

[10:39] Pavithra Kenjige: Superclass vs Subclass .. for something to be subclass of a superclass, it     (1K2AAAAAAAN)

has to meet certain criteria.     (1K2AAAAAAAO)

[10:39] Pavithra Kenjige: Set theory is used to verify subclass and superclass verification     (1K2AAAAAAAP)

[10:40] Pavithra Kenjige: Dr. John F. Sowa would use one of kind of logic to verify such properties .. (     (1K2AAAAAAAQ)

first or second order logic??)     (1K2AAAAAAAR)

[10:42] Steve Ray: In addition, some pointers to some of the tools we have experienced during the     (1K2AAAAAAAS)

Summit, or at least to some of the wiki pages where a reader can go, would be useful in a concrete     (1K2AAAAAAAT)

way. I just worry that we end with a nice academic paper but that doesn't provide some good tips and     (1K2AAAAAAAU)

[10:43] Simon Spero: Terry Longstreth: Deploy cycles are getting faster in some models (this becomes     (1K2AAAAAAAW)

possible when testing is taking place all the time).     (1K2AAAAAAAX)

1_1?s=books&ie=UTF8&qid=1365702215&sr=1-1&keywords=continuous+delivery     (1K2AAAAAAAAA)

[10:48] Terry Longstreth: @Simon - I agree, but however it's done, you still need to package and     (1K2AAAAAAAAB)

deliver something     (1K2AAAAAAAAC)

[10:52] Simon Spero: @TerryLongstreth: delivery in many cases is QA pushing the button to allow     (1K2AAAAAAAAD)

applications to move from QA to production.     (1K2AAAAAAAAE)

[10:52] Simon Spero: @Terry: That can be weekly or less depending on the enterprise     (1K2AAAAAAAAF)

[10:53] Terry Longstreth: If QA's doing its job, it has validated the package as having conformed to     (1K2AAAAAAAAG)

all forms and procedures, including appropriate tests of the to-be-delivered package     (1K2AAAAAAAAH)

[10:55] Simon Spero: @Terry: right - else back it goes. The important thing is that testing is     (1K2AAAAAAAAI)

automated throughout the cycle, so that most old-fashioned QA work is done; the same QA resources     (1K2AAAAAAAAJ)

are doing the stuff that is human only     (1K2AAAAAAAAK)

[10:56] Terry Longstreth: @Simon - looks like we're in violent agreement.     (1K2AAAAAAAAL)

[10:56] Terry Longstreth: I have to leave now.     (1K2AAAAAAAAM)

[10:44] Ali Hashemi: I'm imagining a scenario, where the ontology has already largely been developed,     (1K2AAAAAAAAN)

so it is "further along" the phase, but I want to implement an auditing mechanism to ensure that     (1K2AAAAAAAAO)

that evaluation is complete     (1K2AAAAAAAAP)

[10:45] Ali Hashemi: the current language is geared / tailored to those who are just embarking on an     (1K2AAAAAAAAQ)

ontology development process, as opposed to those who may have already developed to some degree.     (1K2AAAAAAAAR)

[10:45] Simon Spero: @AliHashemi: define "evaluation is complete"?     (1K2AAAAAAAAS)

[10:46] Ali Hashemi: @Simon - so that the evaluation procedure that is utilized covers all the points     (1K2AAAAAAAAU)

that are elaborated in the lifecycle phases     (1K2AAAAAAAAV)

[10:47] Ali Hashemi: complete in evaluating all the various ways that we can evaluate ontologies     (1K2AAAAAAAAW)

[10:47] Matthew West: The evaluation is complete when conformance (or not) to all stated requirements     (1K2AAAAAAAAX)

has been established.     (1K2AAAAAAAAY)

[10:48] Amanda Vizedom: Look at first full paragraph on page 3 for discussion of blending cycles,     (1K2AAAAAAAAZ)

variation in sequence, iterations, etc.     (1K2AAAAAAAAAA)

[10:49] Ali Hashemi: @Amanda, that comes much closer to addressing my question. Apologies if it was     (1K2AAAAAAAAAB)

pointed out earlier. Will add a comment to the document if appropriate.     (1K2AAAAAAAAAC)

[10:53] Amanda Vizedom: @Ali, no problem, and thanks for feedback. This session format is difficult     (1K2AAAAAAAAAD)

because we are only skimming through the document and briefly mentioning things we say, so the     (1K2AAAAAAAAAE)

detailed way that we may have addressed points is not conveyed.     (1K2AAAAAAAAAF)

[10:52] Michael Grüninger: Since notions of ontological errors and correctness are not addressed in     (1K2AAAAAAAAAG)

the "Ontological Analysis" section, we may want to include a forward pointer to say that such     (1K2AAAAAAAAAH)

notions will be addressed later in the "Formal Modeling" section.     (1K2AAAAAAAAAI)

[10:56] Joanne Luciano: I have to leave now too.     (1K2AAAAAAAAAJ)

[10:56] Amanda Vizedom: Perhaps we need a extension of the diagram that shows entry by different     (1K2AAAAAAAAAK)

kinds of potential evaluators: (1) folks at the beginning of an ontology lifecycle, (2) folks with     (1K2AAAAAAAAAL)

an ontology existing, (3) folks looking to reuse an existing ontology.     (1K2AAAAAAAAAM)

[10:59] Steve Ray: Again, in the System Design Phase, I would suggest some references to standard     (1K2AAAAAAAAAN)

tomes on system design.     (1K2AAAAAAAAAO)

[11:02] Amanda Vizedom: @Steve, agreed. We have a note on our off-line working document that we need     (1K2AAAAAAAAAP)

such references. We're open to suggestions.     (1K2AAAAAAAAAQ)

[11:04] Steve Ray: Uh oh. The Model Build Phase / Informal Modelling / Evaluation section makes a     (1K2AAAAAAAAAR)

backward reference to "Ontological Analysis", where I thought that you had just agreed with     (1K2AAAAAAAAAS)

Michael's suggestion that the ontological analysis section makes reference to the Model Build Phase.     (1K2AAAAAAAAAT)

[10:59] Pavithra Kenjige: For that we have to map the concepts to Ontology usage. If it is software,     (1K2AAAAAAAAAV)

during and after deployment .. it is testing phases and maintenance phace.     (1K2AAAAAAAAAW)

[10:59] Joanne Luciano: to all... I'm wondering if the semantic methodology and diagram we use at TWC     (1K2AAAAAAAAAX)

RPI (Fox and McGuinness) (the diagram is in the presentation on GOEF) that might be a better fit for     (1K2AAAAAAAAAY)

the communique (if we keep a diagram). sorry i have to go now -     (1K2AAAAAAAAAZ)

[11:07] Peter P. Yim: @Joanne [10:59] - are you referring to the slide that is labeled: "Semantic Web     (1K2AAAAAAAAAAA)

Development Methodology"? (slide#2 on the slide deck -     (1K2AAAAAAAAAAB)

_Launch/OntologySummit2013_HC-02_GOEF-iChoose_HackathonClinic--JoanneLuciano-et-al_20130328.pdf     (1K2AAAAAAAAAAD)

[11:01] Matthew West: Apologies. I need to leave now.     (1K2AAAAAAAAAAE)

[11:02] Peter P. Yim: @Fabian - why are we calling it "Model Build" Phase and not "Ontology Build"     (1K2AAAAAAAAAAF)

[11:02] Peter P. Yim: I think the latter is more appropriate     (1K2AAAAAAAAAAG)

[11:12] Amanda Vizedom: re: "Ontology" vs "Model" We don't object to this replacement. Amanda favors     (1K2AAAAAAAAAAH)

[11:14] Peter P. Yim: +1 "Ontology Build" please     (1K2AAAAAAAAAAJ)

[11:16] Fabian Neuhaus: concerning "model", just as historical explanation: in some previous version     (1K2AAAAAAAAAAK)

I tried to make the distinction between the track A view and track B view by talking about     (1K2AAAAAAAAAAL)

ontology-as-model and ontology-as-system, during the editing process this was shortened     (1K2AAAAAAAAAAM)

[11:08] Steve Ray: Minor point under Formal Modeling: Suggest not using the term "OWL Full" which is     (1K2AAAAAAAAAAN)

no longer used with OWL 2.0.     (1K2AAAAAAAAAAO)

[11:09] Simon Spero: Steve Ray: ""OWL 2 Full" is used informally to refer to RDF graphs considered as     (1K2AAAAAAAAAAP)

OWL 2 ontologies and interpreted using the RDF-Based Semantics." -     (1K2AAAAAAAAAAQ)

[11:10] anonymous morphed into Pavithra Kenjige     (1K2AAAAAAAAAAS)

[11:11] Fabian Neuhaus: Michael: add concrete example for ontology adaption     (1K2AAAAAAAAAAT)

[11:14] Steve Ray: Page 7: Suggest editing "Structural properties include branching factor, density,     (1K2AAAAAAAAAAU)

counts of ontology constructs, averages, and the like are intrinsic." to "Structural metrics include     (1K2AAAAAAAAAAV)

branching factor, density, counts of ontology constructs, averages, and the like."     (1K2AAAAAAAAAAW)

[11:15] Julien Corman: Just a reaction to the definition on page 7 : The domain is represented     (1K2AAAAAAAAAAX)

accurately if all axioms within the ontology are true. In order to accurately represent the domain,     (1K2AAAAAAAAAAY)

one may also require this axiomatization to be strong enough, i.e. the set of interpretations     (1K2AAAAAAAAAAZ)

satisfying this ontology to be restricted enough, so that the ontology actually rules out unintended     (1K2AAAAAAAAAAAA)

usage, or misunderstanding of its concepts. Page 4, it is suggested that the documentation should be     (1K2AAAAAAAAAAAB)

unambiguous enough, but this could be a requirement for the ontology as well.     (1K2AAAAAAAAAAAC)

[11:27] Amanda Vizedom: @Julien, yes, thank you for making that point. It is one we noted as needing     (1K2AAAAAAAAAAAD)

further discussion but not get to. One of our top-level questions is about intelligibility. This     (1K2AAAAAAAAAAAE)

must include whether the interpretations supported by the ontology are those intended!     (1K2AAAAAAAAAAAF)

[11:15] Pavithra Kenjige: Are you all establishing that Ontology is separate from software all the     (1K2AAAAAAAAAAAG)

time or in some cases?     (1K2AAAAAAAAAAAH)

[11:21] Peter P. Yim: @PavithraKenjige - that would depend on what you mean by "separate" ... if that     (1K2AAAAAAAAAAAI)

means "not equivalent to," then, I'd say the answer is: "yes, all the time"     (1K2AAAAAAAAAAAJ)

[11:21] Fabian Neuhaus: @pavithra: we try to accommodate the fact that there is a view of     (1K2AAAAAAAAAAAK)

ontologies/knowledge base as data bases. This is the view from track B. In that sense ontologies are     (1K2AAAAAAAAAAAL)

software. Then there is a view of ontology as a model of reality. In that sense it is not software,     (1K2AAAAAAAAAAAM)

but just a set of declarative statements written in some formal language.     (1K2AAAAAAAAAAAN)

[11:31] Doug Foxvog: @Fabian, @Pavithra: It is useful to define different kinds of ontology: basic     (1K2AAAAAAAAAAAO)

definitional ontologies, theory ontologies, and knowledge bases.     (1K2AAAAAAAAAAAP)

[11:24] Pavithra Kenjige: Ontology is conceptual .. but most of the time, it is used to build or by     (1K2AAAAAAAAAAAQ)

[11:26] Pavithra Kenjige: One outcome of Ontology can be logical and physical design and development     (1K2AAAAAAAAAAAS)

stages and deployment & usage are referred to as databases ..     (1K2AAAAAAAAAAAT)

[11:35] Pavithra Kenjige: @DougFoxvog, you have a good point. We have discussed domain and usage.. .     (1K2AAAAAAAAAAAU)

[11:27] Todd Schneider: Fabian, Track B presented the notion that there is a large similarity between     (1K2AAAAAAAAAAAV)

ontology and relational databases, hence many of the evaluation techniques from that field maybe     (1K2AAAAAAAAAAAW)

used, with modification, for ontology evaluation.     (1K2AAAAAAAAAAAX)

[11:29] Peter P. Yim: (ref. verbal suggestion) - Recommendations should be in a separate section ...     (1K2AAAAAAAAAAAY)

maybe putting them with (as proposed in the outline) "Future Steps What issues need to be addressed     (1K2AAAAAAAAAAAZ)

to improve ontology evaluation and its adoption by ontology developers?" would be fine (... but not     (1K2AAAAAAAAAAAAA)

with support or tools)     (1K2AAAAAAAAAAAAB)

[11:24] Steve Ray: I think we could help a lot by providing links to the tools we have uncovered     (1K2AAAAAAAAAAAAC)

during this Summit.     (1K2AAAAAAAAAAAAD)

[11:31] Fabian Neuhaus: link to summary pages wiki     (1K2AAAAAAAAAAAAE)

[11:31] Fabian Neuhaus: link to wiki page tools     (1K2AAAAAAAAAAAAF)

[11:29] Steve Ray: Logistics question: Can we somehow allow comments by all us reviewers on the     (1K2AAAAAAAAAAAAG)

[11:32] Ali Hashemi: @Amanda, i thought you can highlight text within the document to add a comment     (1K2AAAAAAAAAAAAI)

to a specific word/sentence/paragraph     (1K2AAAAAAAAAAAAJ)

[11:32] Ali Hashemi: You should be able to have the Share setting be "add comment" with link     (1K2AAAAAAAAAAAAK)

[11:32] Amanda Vizedom: Comments on the Google doc are now enabled.     (1K2AAAAAAAAAAAAL)

[11:37] Amanda Vizedom: To comment, select the text you want to comment on, then right click and     (1K2AAAAAAAAAAAAM)

select "comment". Enter your comment an save.     (1K2AAAAAAAAAAAAN)

[11:35] Torsten Hahmann: @Peter: (responding to Peter's call to tools developers to respond to the     (1K2AAAAAAAAAAAAO)

Survey) I did update some of the information on the survey, please check that.     (1K2AAAAAAAAAAAAP)

[11:35] Peter P. Yim: @Torsten - this is great! I didn't check lately!     (1K2AAAAAAAAAAAAQ)

[11:37] Simon Spero: ;;;; good work     (1K2AAAAAAAAAAAAU)

[11:37] Peter P. Yim: Great job, Fabian and Amanda!     (1K2AAAAAAAAAAAAW)
