Ian Horrocks: Peter -- unmute yourself! PeterYim: can you hear me now? anonymous1 morphed into Alan Rector Tracy Safran: Is the conference ID still Conference ID: "4389979#" ?

I will advance the slides on your prompt anonymous morphed into Trang PeterYim: could you tell us who you are, please, "Trang"? LeoObrst: Peter, I had disconnected, but at the time only Ian and I could hear each other. I'm assuming everyone can hear now. ToddSchneider: Ian, can you provide some references to the research referred to in "Research has now shown how some restrictions can be overcome"? PeterYim: for those who are not using your real names, kindly morph into your real name (WikiWord format preferred) so we can properly attribute your contributions ... try not to use initials, or just your first name or last name ... Alan Rector morphed into AlanRector anonymous morphed into HIrankitti michael riben: MichaelRiben PeterYim: we are holding off Q&A until *after* the presentation ... feel free to capture question on this chat board while the presentation is in progress Rob McClure morphed into RobMcClure ToddSchneider: Ian, late could you explain the use of UML in the OWL 2 specification? Brian Haugh: Does OWL2 support multi-media objects, such as audio, images, and video? Cui Tao: Can we define a new data type by referring or mapping it to a pre-defined data type such as an ISO data type? Brian Haugh: How well do reasoners support reasoning with the content of annotations? doug foxvog: This treatment of "punning" would then prevent rules like "If ?SPECIES isa EndangeredSpecies & ?PREY isa ?SPECIES & ?HUNTER isa LicencedHunter and ?HUNTER kills ?PREY, then ..." Cui Tao: Ian, could you refer us some examples of annotation of annotations? Is it some sort of reification? AlanRector: Slide 15: Manchester Syntax error? "...that isPartOf CirculatorySystem" --> "...that isPartOf _some_ CirculatorySystem" Cui Tao morphed into CuiTao doug foxvog: An annotation of an annotation would include providing a timestamp and author of an annotation. CuiTao: Yes. I meant how that is done in OWL2. Is it through reinfication? ToddSchneider: Ian, could you define 'saturation' in the context your using it? TomRuss: Are there any plans to add a standard query language to OWL? Especially one that allows for asking queries that return tuples rather than just single individuals. In other words, something that goes beyond DL Query. Brian Haugh: How is bi-directional RDF mapping supported for OWL 2 with assertion annotations, when RDF does not support assertion annotations? Paul Hermans: Thank you Mike Hewett: Very nice talk. PeterYim: @Ian - since I don't have "voice", would you be kind enough to moderate the Q&A, please? JimRhyne: What's next for OWL? How will the recent meeting on RDF next steps influence OWL? PeterYim: ALL: please press the "hand button" (at lower right) and queue yourself up to make a remark PeterYim: ALL: note that questions captured on the chat should be looked at as "placeholders" ... please queue up to verbally discuss those questions or issues PeterYim: again - to unmute, press "*3" (make sure you are heard, and identify yourself please, before asking your question) ... after you're done, please go back to "mute" again with a "*2" doug foxvog: Metareasoning exists & is performed in Cyc.
