== Proceedings ==
[12:02] AlexShkotin: hi! sorry i do not have microphone today

[12:15] David Whitten: Is it possible that the semantics is in the Montague lamba expressions?

[12:16] David Whitten: Context re Ontology use or development or re-use

[12:17] David Whitten: I thought the context for the semantics in a IC sense must be in the "global variables" shared among processes.

[12:18] David Whitten: Pragmatics in Linguistics is over more than a sentence.

[12:24] David Whitten: 1) Physical Context, 2) Linguistics/Topic Context 3) Conceptual Context 4) Deductive Context

[12:30] David Whitten: Physical Context changes as things happen near you. Linguistic Context changes as the conversation statements are made.  Conceptual Context is based on "Common Sense" or world-knowledge increases.

[12:33] David Whitten: Are the Linguistic reasons to parse related to the "Speech Actions" coming from the sentence ?

[12:38] David Whitten: A Deductive Context depends on logic. This adds a new relation for each n-ary relation with an extra argument which is the context.  Alternately if you allow the expression of a relation to be quoted, then you can add other information to the quoted relations.

[12:41] David Whitten: IKL based on Common-Logic was a two year project with two dozen participants that added the "that" statement to Common Logic as the form to do quoting.  This allows meta-languages, evaluation of the quoted statement with different contexts, etc. "ist" (is-situation-true?) can be defined in terms of that.

[12:42] David Whitten: ist captures the idea that a group of statements is true in the context/situation of another group of statements.

[12:43] David Whitten: Is this a way of formalizing in the interactions of statements with microtheories

[12:44] RaviSharma: David says language is well define and is willing to talk about that in one of our sessions.

[12:44] David Whitten: John Sowa, thanks for offering to give a talk about IKL.

[12:47] David Whitten: Pat Hayes website for IKL GUIDE is https://www.ihmc.us/users/phayes/IKL/GUIDE/GUIDE.html

[12:48] RaviSharma: who is speaking?

[12:49] David Whitten: Not Pat Hayes nor John Sowa. maybe Gavin ?

[12:49] RaviSharma: Is it David?

[12:50] MikeBennett: Matthew West is speaking now.

[12:50] RaviSharma: thanks

[12:56] John Sowa: Leo wrote this paper in 2005, while he was also participating in the IKRIS project, which produced IKL.

[12:56] David Whitten: Leo gives a list of meanings for Contexts. I assume everyone is using a definition of "ontology" that is compatible with the definition of an ontology as a set of propositions that as a whole are true without any contradictions.

[12:58] John Sowa: The 'that' operator is the mechanism for annotating a group of statements as a context.

[13:02] David Whitten: the ist operator started from John McCarthy, a context might be made from 'that' and an ontology or 'that' and a situation or 'that' and a microtheory. ist then would take one of these contexts and a statement and generate a truth value.

[13:05] David Whitten: a group in Germany (?who?) has implemented a Common Logic system that could be augmented with 'that' to make an IKL implementation.

[13:08] David Whitten: Ravi Sharma, and Matthew West and Ken Baclawski have open mikes.

[13:12] David Whitten: John Sowa wants to recognize that there is a difference two ways context can be used.

[13:13] RaviSharma: finally I found and turned off my microphone - thanks

[13:14] RaviSharma: will all these papers be put on the recording or this chat as links I know Pat's is already there?

[13:14] David Whitten: John says two models for "simple" 1)Simpler for make a Tarski model theory or 2) Simpler for editing/managing logical statements

[13:15] RaviSharma: David thanks kindly keep making notes as I am also on another call.

[13:16] RaviSharma: Is Ken speaking now?

[13:16] David Whitten: a "nominal" in this hybrid logic serves as a context for another logic, such as an FOL or modal logic.

[13:16] RaviSharma: or is it still John?

[13:17] John Sowa: You can map hybrid logic to IKL.  The 'that' operator of IKL is syntactically simple, but semantically very powerful,

[13:17] David Whitten: This is Ken. definitely not John

[13:17] RaviSharma: thanks

[13:17] John Sowa: The that operator can represent both modal logic and hybrid logic.

[13:20] David Whitten: The hybrid logic shown on the screen is from https://plato.stanford.edu/entries/logic-hybrid/

[13:21] RaviSharma: David if you could also kindly put links for other papers, it would help us. thanks.

[13:21] RaviSharma: John Sowa is speaking now.

[13:22] David Whitten: Hybrid Logic and IKL can both enhance a base logic.   Common Logic is a specific formal definition of a superset of FOL.

[13:23] David Whitten: the that operator in IKL is similar to the phrase followed by the word "that" in English

[13:24] MatthewWest: Apologies, I have to leave now.

[13:25] RaviSharma: John - Is this also used to help in transliteration? or translation?

[13:25] David Whitten: the 'that' operator of IKL allows for naming a group of logical statements.  The 'ist' operator allows testing truth for a statement with a group of logical statements.

[13:27] RaviSharma: John will be giving the talk next week

[13:27] David Whitten: Might be nice to know if Leo Orbst agrees as well as Pat Hayes and Chris Menzel

[13:28] RaviSharma: could you talk if they do not, Ken we can request David?

[13:28] RaviSharma: David for 27th?

[13:29] David Whitten: I'll consider a talk for the 27th. It might have a medical slant tho.

[13:29] David Whitten: I do medical informatics with the VistA EHR for a living

[13:29] RaviSharma: yes that would be nice.

[13:30] KenBaclawski: Meeting adjourned.

[13:30] RaviSharma: ken where do I see recording and hear it?

[13:31] David Whitten: I don't know who the mp3 creator is now.

[13:31] ToddSchneider: Ravi, Ken will post a link on today's meeting page.

[13:31] David Whitten: I think it might have been Peter Yim before.

[13:31] ToddSchneider: David, Ken is.

[13:32] KenBaclawski: The recording will be posted on the meeting page.

[13:33] RaviSharma: thanks
