Ontology Generation and Harmonization     (2A)

Ontologies are a rich and versatile construct. They can be extracted, learned, modularized, interrelated, transformed, analyzed, and harmonized as well as developed in a formal process. This summit will explore the many kinds of ontologies and how they can be manipulated. The goal is to acquaint both current and potential users of ontologies with the possibilities for how ontologies could be used for solving problems.     (2A1)

Different types of ontologies have different uses and require different techniques. Some major types include: foundational, reference, domain, and application ontologies. The different types overlap. This track will survey the landscape of ontology types and propose guidelines on how to identify the type of an ontology and how to use it.     (2A3)

A definition is a formal statement of the meaning or significance of an entity, including words, phrases, classes and properties. Accordingly, definitions can serve as links between formal ontologies and informal ontologies as well as between different formal ontologies. Historical attempts to standardize terms included creating core metadata models and common conceptual models for combining data into a single representation. These however have largely failed to be adopted because of flawed conceptualizations, lack of community agreement, inadequate representation and thus amount to siloes. Some progress has been made leveraging best practices including the use of ontological analysis and design. This track will survey the different notions and levels of formality of definitions and practical methods to harmonize a variety of semantic resources.     (2A5)

Ontologies can now be created using automated techniques such as NLP and ML. This track will survey the current techniques, including neuro-symbolic and commonsense approaches that combine logic and language processing. The goal is to propose guidelines on the most appropriate use of the techniques.     (2A7)

Many organizations, including government agencies, standards bodies and commercial firms, use ontologies and have developed tools for various ontological activities, such as creation, evolution, mapping and other forms of harmonization. This track will survey organizations that have been most active in ontology engineering.     (2A9)

Participants     (2D)

Discussion     (2E)

[11:42] DrRaviSharma: Ravi welcomes all     (2E1)

[11:56] KenBaclawski: Hello Ravi, Dave, Doug     (2E2)

[11:56] KenBaclawski: Hello Ravi, Dave, Doug     (2E3)

[12:03] Douglas R. Miles: no Dave or Ravi on Zoom yet     (2E4)

[12:15] Douglas R. Miles: Ken can you post the Topics summary ?     (2E5)

[12:15] ToddSchneider: Gary, I suspect when I talk about 'types' of ontologies I will include aspects of 'definition' (as used in ontologies).     (2E7)

[12:16] Douglas R. Miles: thx @Cas     (2E8)

[12:16] Cas Miles: @Douglas np     (2E9)

[12:20] ToddSchneider: What constitutes a 'landscape'? Does this include domains on use?     (2E10)

[12:33] Cas Miles: one sec!     (2E11)

[12:34] Cas Miles: Douglas just sent a message saying he wanted to talk, sorry!     (2E12)

[12:35] DrRaviSharma: thanks Doug     (2E13)

[12:36] DrRaviSharma: two sessions Doug and Ram one each     (2E14)

[12:37] DrRaviSharma: Doug said - using NL translation - using ... Dolce and ...Cyc's     (2E15)

[12:37] GaryBergCross: @Todd I think of definitions as one type of semantic resource. It included NL whose "semantics" is not formal but is understandable to humans. I don't think of them as ontologies, but as implying some meaning that can be formalized into a ontology.     (2E16)

[12:40] DrRaviSharma: Doug is using collections and individuals - cyc upper ontology -Cyc ontology and Application converting into language     (2E17)

[12:40] DrRaviSharma: Cas - introducing NLP prerequisites.     (2E18)

[12:41] GaryBergCross: @Doug I would suggest that we show, as part of Track 2, a small example of how you would translate 1 0r 2 sentences into a logical form. You can follow up and expand on this in your session.     (2E19)

[12:41] DrRaviSharma: 3 sessions for C also     (2E20)

[12:47] Douglas R. Miles: @GaryBergCross that is a great idea     (2E21)

[12:47] DrRaviSharma: Track D might be 3 sessions     (2E22)

[12:47] DrRaviSharma: Mark-and Todd will coordinate - e g European Efforts.     (2E23)

[12:48] DrRaviSharma: so 12 sessions+ 2 synthesis and an overview session =15     (2E24)

[12:50] DrRaviSharma: Then communique so 15+ 2-3 sessions for communique or summit     (2E25)

[12:51] DrRaviSharma: Communique is ready but for NIST review for which Ram estimates 2 weeks or so.     (2E26)

[12:54] DrRaviSharma: how to build ontology of given type to be covered by track A     (2E27)

[12:55] DrRaviSharma: Best practices -     (2E28)

[12:55] DrRaviSharma: top down vs bottom up     (2E29)

[12:58] Mark Underwood: Have to hop on another meeting - Be well     (2E30)

[12:59] DrRaviSharma: Gary said lead-in material before the tracks     (2E31)

[12:59] DrRaviSharma: Leo's diagram in A     (2E32)

[13:00] ToddSchneider: Have to go.     (2E33)

[13:01] DrRaviSharma: Gary thinks it in the light of context to get to A     (2E34)
