Abstract
OntologySummit2013 Session-10: "Software Environments for Evaluating Ontologies - II" - intro slides

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."

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.

During this OntologySummit, 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.

At the Launch Event on 17 Jan 2013, the organizing team provided an overview of the program, and how we will be framing the discourse around the theme of of this OntologySummit. Today's session is one of the events planned.

In this 10th virtual panel session of the Summit, we have invited the stewards of some exemplary ontology software tools and environments out there to join us on the panel. They will share with us their work, experience and insights - particularly on how the software environments/systems/tools they represent, support evaluating intrinsic aspects and extrinsic aspects of ontologies, and how they help assure quality across the lifecycle of the development (of the ontology or the ontology-driven application). We will also hear about what they think are the major obstacles now, toward quality excellence, relevant work they are embarking on, and wish lists of what have yet to be done in term of improving ontology quality.

We will also expecting to be "officially" launching the OntologySummit2013 Survey of Software Support for Ontology Quality and Fitness, which we alluded to earlier, at this session.

Briefings:
Upper Merged Ontology (SUMO), starting over 12 years ago. It is an open source program, hosted on SourceForge (at http://sigmakee.sourceforge.net), and is coded in Java and JSP. Sigma includes interfaces to dozens of first-order and higher-order theorem provers, and optimization code to take best advantage of those provers when running over the SUMO theory. Sigma includes many static checks for testing the quality and correctness of expressive theories. It also has a growing body of textual analysis modules for information extraction and sentiment analysis. The system also supports browsing the WordNet lexico-semantic database, and its complete set of manually-coded links to SUMO. Sigma functions as a modern IDE for development of expressive theories, where actual coding is performed in a text editor and the IDE assists with debugging and visualization of the code. This talk will give a very brief introduction to these features.

 * Prof. Dr. TillMossakowski (University of Bremen) - "Ontohub.org - a web platform for distributed and heterogeneous ontologies"  slides
 * Abstract: ... Ontohub.org is a web platform that goes beyond platforms like Bioportal in that it supports a multitude of ontology languagegs (OWL, RDF, Common Logic, first and higher-order logic, ...) as well as heterogeneous distributed ontologies. Ontohub also supports the structuring constructs of the distributed ontology language DOL, see http://www.ontoiop.org . Ontohub generally follows the architecture of the Open Ontology repository, see http://ontolog.cim3.net/cgi-bin/wiki.pl?OpenOntologyRepository_Architecture/Candidate03, although currently it has not yet been fully split into a number of independent services. Ontohub is implemented in Ruby on Rails and is freely available at https://github.com/ontohub/ontohub . As analysis and reasoning backend, Ontohub uses the heterogeneous tool set (Hets), see http://hets.dfki.de , which is in turn connected to various theorem provers and model finders. In this talk, we will introduce Ontohub and discuss its use for ontology evaluation.


 * Dr. TaniaTudorache (Stanford-BMIR) - "WebProtege and BioPortal as Infrastructures for Ontology Evaluation"  slides
 * Abstract: ... In the recent years, we have witnessed an increased adoption of ontologies in a wider range of domains, with biomedicine being the front runner. Users need now, more than ever, support for finding and assessing ontologies that are suitable for their particular task. Several approaches presented in this forum, are investigating the algorithmic side of evaluating ontologies. We will talk about the qualitative aspect of ontology evaluation, in which users act as reviewers of ontologies, similar to the process of scientific paper review. We will present WebProtege and BioPortal, two complementary Web-based systems that provide the essential infrastructure for documenting, reviewing, discussing and finding the "right" ontologies. WebProtege is a light weight ontology editor for the Web that provides extensive collaboration support. BioPortal is an open-source repository of over 300 biomedical ontologies with support for documentation, discussion and reviewing of ontologies. We will show how the seamless integration of WebProtege and BioPortal create a comprehensive infrastructure for ontology evaluation.


 * Professor MichelDumontier (Carleton University) - "Evaluation of ontology-powered scientific research as a means to assess and improve ontology quality"  slides
 * Abstract: ... Ontologies are quickly becoming a core part of biomedical infrastructure, where they serve as a means to standardize terminology, to enable access to domain knowledge, to verify data consistency and to facilitate integrative analyses over heterogeneous biomedical data. Given the increased use of ontologies in scientific research, we must first consider the consistent evaluation of ontology-powered research so as to quantitatively evaluate the contribution of the ontology to the effort. Quantitative evaluation of research could then lead to systematic improvement of the application and performance of an ontology (as a key measures of quality) and enable the comparison of any ontology to the overall result. With the emergence of vast amounts of relatively schema-light biomedical Linked Open Data such as that provided by the open source Bio2RDF project, new opportunities arise for applying, evaluating and increasing the utility of ontologies in biomedical research.

[9:48] PeterYim: == AdamPease presenting ... see: the [1-Pease] slides

[9:53] SimonSpero: What about horses that only have three legs

[9:54] SimonSpero: "A horse like that, you don't eat all at once"

[10:00] TillMossakowski: is the translation from SUO-KIF to OWL described somewhere?

[10:00] AmandaVizedom: Question for @AdamPease: Any plans for support of Common Logic?

[10:11] MichaelGruninger: There is a long history behind the relationship of KIF and CL. KIF 3.0 (which is the last available document for KIF) evolved into Common Logic, but KIF also included a lot of other notions (such as set theory and metalanguage) that are not contained in Common Logic (which is the standard ISO 24707). Common Logic without sequence variables is first-order expressive. I'm not sure about the precise formal relationship of SUO-KIF and Common Logic -- this would require a closer look at the relationship of SUO-KIF and second-order logic.

[10:13] TorstenHahmann: There is a CL to KIF, Prover9, and TPTP translator available from https://github.com/cmungall/cltools; it is in Prolog. It translates the first-order portion of CL. I have developed wrappers to translate (and evaluate) large sets of CL ontologies, I'm currently moving all the source to a Github project: https://github.com/thahmann/macleod

[10:08] AmandaVizedom: Comment: I strongly agree with this point: having enough content to perform interesting inferences, and having ready/easy inference capability ready to hand, makes certain kinds of error detection and debugging much easier and more naturally integrated into development process.

[10:09] anonymous1 morphed into PavithraKenjige

[10:41] AdamPease: just reading the chat logs

[10:42] AdamPease: KIF and SUO-KIF are quite different, so unless it's specifically a SUO-KIF translator, it won't work for SUMO

[10:42] AdamPease: translating CL to the first-order subset of SUO-KIF should be easy

[10:42] TillMossakowski: I think in Hets we have some translation of SUO-KIF into Common Logic

[10:43] AdamPease: I included a presentation of that in Sigma at one point I think, mainly just renaming some of the logical symbols as I recall

[10:44] AdamPease: that sounds great Till

[10:45] PeterYim: @AdamPease: re your xx:43where can one find that presentation ... can you supply a link to it?

[10:45] AdamPease: ?

[10:45] AdamPease: oh, not a slide presentation

[10:46] AdamPease: a presentation of logic

[10:46] PeterYim: @Adam: this is in reference you your earlier statement "I included a presentation of that in Sigma at one point ..." ... can you supply a link to that presentation?

[10:46] AdamPease: use the "traditionalLogic" menu option in the menu title "Formal Language" in the Sigma browser

[10:47] PeterYim: Ah ... thanks, Adam

[11:01] TorstenHahmann: @AdamPease: Adam, you mentioned that the KIF version of SUMO can be automatically translated to OWL. can you expand a little on how that works (or give me a pointer)? Which OWL variant (OWL-DL?) do you translate to? In particular, I would think you would need to consider all entailments of the first-order ontology to ensure that the translation is complete (with respect to the expressivity of OWL). How do get around this?

[11:02] TillMossakowski: interesting question!

[11:03] AdamPease: I make no claims that it's a complete translation

[11:03] AdamPease: especially since OWL is so limited

[11:03] AdamPease: but even within its limitations, we don't do anything extraordinary

[11:03] AdamPease: all binary relations get translated

[11:04] AdamPease: we translate all the builtin terms in OWL to their equivalents in SUMO

[11:04] AdamPease: all rules get turned into comments

[11:04] AdamPease: that's about it

[11:06] TorstenHahmann: thanks, I was just wondering

[10:20] anonymous1 morphed into MarcelloBax

[10:06] JoelBender: Isn't there a CL to KIF translator?

[10:06] SimonSpero: Hets sort of does that

[10:07] SimonSpero: for certain senses of KIF

[10:08] SimonSpero: Hets module CommonLogic.Parse_KIF

[10:07] MatthewWest: KIF is a dialect of CL

[10:19] PeterYim: TillMossakowski - see: http://ontohub-new.informatik.uni-bremen.de/

[10:25] PeterYim: == TaniaTudorache presenting ... see: the [3-Tudorache] slides

[10:30] DougFoxvog: Tania's Slide 4 mentions "Contextual notes and discussions attached to any entity in the ontology". Can such notes be attached to statements, or merely to the terms?

[10:37] AmandaVizedom: Question for @TaniaTudorache: Is it correct to say that Web Protege supports collaborative manual evaluation, and potentially documentation of automated or semi-automated evaluation and/or metrics gathering that others may have done independently, but does not support such evaluation itself?

[10:39] PeterYim: @TaniaTudorache: can one access the collected user review input, and slice-and-dice that data ... I guess its, sort of, the same question Amanda is asking

[10:41] DougFoxvog: Ref Slide 12. What about an ontology for encoding the reviews using relations & terms defined in the ontology?

[10:42] AmandaVizedom: Comment: Tania's slide 12 regarding issues with review suggests, to me, that it would be helpful to have a common understanding of ontology characteristics and evaluation metrics/techniques, such that these could be explicitly addressed in reviews. One would like to see reviews evolve to focus on such shared questions.

[10:41] PeterYim: == MichelDumontier presenting ... see: the [4-Dumontier] slides

[10:51] AmandaVizedom: Comment: Just noting, per @MichelDumontier's slide 3, that GO is a controlled vocabulary (common in domain, I think) -- i.e., the "nodes" are NL expressions. I wonder whether the significance of annotation change patterns, for example, would be different for a concept-centric ontology, with (potentially multiple) NL expressions associated, that for a controlled vocabulary like this.

[10:53] AmandaVizedom: (I would think so; the concept-centric ontology with lexical mappings should be less brittle to language change than the controlled vocab. In any case, it's a good example of the importance of being clear what kind of KR artifact you are dealing with before you can understand what to evaluate and how to interpret it.

[10:57] AmandaVizedom: @Michel - re slide 11: Great examples of how different kinds of evaluation can be more or less relevant depending on how the ontology is going to be used (or reused).

[11:15] MichelDumontier: @Amanda - The GO has made strides to be a more conformant "ontology", but I find it confusing/lacking in many respects, but doesn't diminish it's current utility in scientific research. Thanks for the positive comment on slide 11 :)

[11:03] TerryLongstreth: @Michel - Slide 13 - did you subdivide the volunteer community by expertise? Did expertise/experience make any difference?

[11:10] MichelDumontier: @Terry - the volunteers were experts at a conference on the topic

[11:11] TerryLongstreth: Thanks, Michel.

[11:11] PeterYim: == KingsleyIdehen presenting ... see: the [5-Idehen] slides

[11:16] PeterYim: @ALL: note that Kingsley is working off a slightly updated deck of slides. If you downloaded the slide before he started talking, you might wanted to download the (the updated) slides again

[11:24] MatthewWest: Afraid I need to go now.

[11:25] MichelDumontier: ugh oh ... Kingsley we lost you!

[11:25] MariaPovedaVillalon: yes

[11:25] DougFoxvog: I hear Peter, but not Kingsley

[11:26] SamirTartir: @Peter: I can hear you

[11:26] PeterYim: Kingsley we lost you, on the voice line, can you dial in again, please

[11:26] MichaelDenny: @Kingsley We've lost you!

[11:28] PeterYim: === KingsleyIdehen's talk resumes ... (slide#13)

[11:30] PeterYim: KingsleyIdehen request that AdamPease supply a URI for SUMO that he can link to

[11:30] AdamPease: maybe I'm misunderstanding but we've had that for years

[11:31] AdamPease: http://sigma-01.cim3.net:8080/sigma/OWL.jsp?kb=SUMO&term=Object

[11:31] AdamPease: for example

[11:30] DougFoxvog: URI for terms that denote creators seems too much of a hack. Assertions about who is responsible for a terms set (which would have the same name space) seem to me to be more worthwhile.

[11:33] DougFoxvog: Individual assertion, e.g., (termCreatedBy  ) can be used for attribution.

[11:30] AmandaVizedom: Must drop off. Thanks all!

[11:33] PeterYim: == Q&A and Open Discussion ...

[11:33] PeterYim: Again, soliciting help from everyone here: -- for software environment stewards and tool developers, please make sure you participate in the OntologySummit2013 software survey -- and help us get these colleagues of yours to respond to the survey too: http://ontolog-02.cim3.net/wiki/OntologySummit2013_Survey -- ... or provide us with pointers to stewards of relevant software tools/systems/environments so we can reach out to them

[11:37] PeterYim: join us again, same time next week, for OntologySummit2013 session-11: "Getting the "hackathon," "clinics" and related activities going" - Co-chairs: MikeDean, KenBaclawski & PeterYim - developing session details at: http://ontolog.cim3.net/cgi-bin/wiki.pl?ConferenceCall_2013_03_28

 * 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").
 * 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.
 * 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_20130321@soaphub.org ... Handy for mobile devices!


 * Discussions and Q & A:
 * Nominally, when a presentation is in progress, the moderator will mute everyone, except for the speaker.
 * 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.)
 * 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.)
 * 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.)
