[11:55] KenBaclawski: [1] is a paper on situation awareness and context by Odd Erik Gundersen

[12:08] KenBaclawski: I have given several talks on Situation Awareness at Ontology Summits and other venues. See [2].

[12:08] janet singer: Terms and notions related to ontologies and 'context in context' to be clarified for communique: ontologies, contexts, situations, integration, interoperability

[12:10] janet singer: The paper Ken posted on reseachgate [3]

[12:11] Gary Berg-Cross: Topic is how to include and leverage prior summit ideas in the current summit.

[12:11] Gary Berg-Cross: 1 thing is to have topic co-champions include prior summit knowledge in their synthesis.

[12:12] Gary Berg-Cross: Can we set up the wiki to capture this LT knowledge?

[12:13] Gary Berg-Cross: Curator role or archivist needed.

[12:13] Gary Berg-Cross: Can we use the semantic wiki to discuss things??

[12:13] Gary Berg-Cross: There is a large start up effort needed.

[12:14] Gary Berg-Cross: maybe we start with a good template for the wiki

[12:17] Gary Berg-Cross: One could wish for a small grant to do this...and or academics recruiting a student to do this.

[12:25] Gary Berg-Cross: Ken, do we have a wiki page for each topic set up? I wanted to add more detail on our OKN topic, but didn't see a place for this.

[12:32] Gary Berg-Cross: John's most popular work on Google Scholar is a review Philosophy in the Flesh G Lakoff, M Johnson. New York: Basic books15320 hits1999

Extending and formalizing the framework for information systems architecture JF Sowa, JA Zachman IBM systems journal 31 (3), 590-616 is 2nd with 1414 hits

[12:32] Gary Berg-Cross: Are their slides available???

[12:35] KenBaclawski: @[12:32] Gary Berg-Cross Spencer's slides are at [4]

[12:43] KenBaclawski: @[12:25] Gary Berg-Cross I have not yet set up a wiki page for each track. I did this at the last summit, but it was not used very much. I will create wiki pages.

[12:48] John Sowa: Many years ago, I studied algebraic topology, and I learned all about category theory.

[12:49] John Sowa: I like category theory. But these mappings are only possible if these formal mappings can be done.

[12:50] John Sowa: Unfortunately, the great majority of papers about aligning ontologies start with very, very informal mappings.

[12:51] John Sowa: WordNet, for example, has no formal definitions of any kind. But it's the most widely used tool for aligning ontologies.

[12:52] John Sowa: is another very informal system that is used to align ontologies.

[12:54] John Sowa: Alignment by WordNet or can never ensure that a mapping by category theory is possible.

[12:57] John Sowa: For more info, see Goguen's paper [5].

[12:58] John Sowa: The title of Goguen's article is "Tossing algebraic flowers done the great divide."

[12:58] Gary Berg-Cross: In your examples, like different context for schedules the same as different situations that make for different schedules?

[12:59] John Sowa: Goguen spent his career in applying category theory in computer science.

[13:00] Douglas R. Miles: I find most often Computer Scientists (not necessarily us) feel more comfortable mapping Category theory to Ontologies than the other way around

[13:00] John Sowa: The only people who paid attention are mathematicians who published papers in journals that no practitioner would ever read.

[13:00] Douglas R. Miles: Somehow, one or the other camps often feel the other is a wart

[13:01] Douglas R. Miles: But category theorists have at least signed up for Ontological engineering .. where most haven't

[13:03] Douglas R. Miles: (btw i am speaking in general.. i don't think any OEs feel CT is a wart on the other)

[13:05] Douglas R. Miles: The thing I hope to see (much sooner than never) is that Programmers use Ontology to keep their Program's semantics organized.. CT is the first step

[13:06] John Sowa: Douglas, please read Goguen's article.

[13:06] Douglas R. Miles: its open.. will do

[13:06] Gary Berg-Cross: The original Q was "How can we build ontologies from a given context?" Given the briefing I'm still unclear of what context you started with. Just a situation of object related??

[13:08] Gary Berg-Cross: Every diagram represents a domain which can be used to define a domain context/environment?

[13:14] Douglas R. Miles: when an application is doing specific things using specific models .. we might frame that as a context for all purposes

[13:14] Douglas R. Miles: (for all our purposes when talking about contexts)

[13:16] John Sowa: What button for unmute?

[13:17] Douglas R. Miles: idly recalls a paper linking category theory to Plato's theory of forms ("Category Theory and Concrete Universals" by David P. Ellerman in 1998-05 at [6]), fwiw

[13:19] Gary Berg-Cross: John on lower right and audio off or on toggle.

[13:21] Douglas R. Miles: Yes, John is is hard work even once you know what you are doing!

[13:27] Gary Berg-Cross: "Ontology matching: A literature review." Expert Systems with Applications 42.2 (2015): 949-971. Lorena Otero-Cerdeira, Francisco J. Rodríguez-Martínez, Alma Gómez-Rodríguez, [7]

[13:27] Douglas R. Miles: hrrm so John is saying CT->Ontology always makes sense

[13:28] Douglas R. Miles: Ontology -> CT .. sometimes is crazy

[13:29] Douglas R. Miles: (sometimes gets crazy and it would be better to take smallest bites as what is useful)

[13:30] Douglas R. Miles: For sure a CT is an Ontology

[13:32] Douglas R. Miles: (an application defined in CT is always the proper sized mid level ontology)

[13:32] David Whitten: So Ken, please share your tool.

[13:32] Gary Berg-Cross: Have to go, see you on the Forum.

[13:33] David Whitten: Doug, can you call me? (713)-870-3834 ...

[13:33] Douglas R. Miles: Can do in about 20 minutes

[13:34] David Whitten: Thanks Ken!
