Dr. Hays ( & Dr.Sowa, Doug, John Bottoms), Thank you for the detail explanation about reasoning behind choosing "thing" ( at your discretion) as the universal type. It is a choice to handle unresolved issues at implementation time by using internal consistency checks vs design time resolution to handle semantic overloads for words like string vs string ( at design time, you can have an additional field that indicates context of the usage of the word,etc) and other exhaustive semantic and grammatical issues or differences for all practical purposes. Even though it defeats traditional software engineering principle or best practices to resolve issues at design time vs implementation time, Languages can get complex, since they are used to express complex universe, with four dimensions or n dimensions, I understand you all made a decision go with "thing". My curiosity was more towards Ontology for language or linguistics as a domain ( genetic engineering is a domain or sub-domain for biology) and how it has been handled there. If we start discussing concepts and semantic of words like " meme", ontologists have to eventually model it. For example SUMO has addressed linguistics. I wonder how they have implemented it.. http://www.ontologyportal.org The Suggested Upper Merged Ontology (SUMO) and its domain ontologies form the largest formal public ontology in existence today. They are being used for research and applications in search, linguistics and reasoning. SUMO is the only formal ontology that has been mapped to all of the WordNet lexicon. SUMO is written in the SUO-KIF language. SUMO is free and owned by the IEEE. The ontologies that extend SUMO are available under GNU General Public License. Adam Pease is the Technical Editor of SUMO. Thanks.

The base layer is the actual external world, the world of objects. Houses, for example, are in this basic layer. Then language comprises the next layer, which describes the first layer, and words live in this second, language, layer. And perhaps meta-linguistic knowledge, such as disussions of grammatical relationships between words, lives in a third layer lying even higher. But in any case, the layering is strict, and is necessary to avoid paradoxes and perhaps infinite loops in programming, so you object to ideas which seem to violate this clean layered division, by for example using categories (like Doug's and my "thing") which bridge across two or more layers. > > If I have this is more or less right, then I would suggest that you might want to consider abandoning this layering idea. It does not really correspond with anything real, and it is not necessary. It reflects a very early approach to avoiding the semantic paradoxes, but this approach was abandoned by mathematicians nearly a century ago in favor of more modern approaches to set theory (which are now considered standard, most notably Zermelo-Fraenkel set theory, dating from 1922) which do not force this rigid hierarchy of levels upon the universe. (Indeed, more recent work has shown that it is quite possible to have set theories which violate the 'layers' idea even more sharply, for example by requiring that all sets have infinitely descending chains of subsets, so there is no "bottom" to the universe. I mention this not to recommend such odd theories, but only to illustrate that the idea that a strict hierachy of levels is somehow necessary, or required in order to keep things consistent, is quite wrong.) The IKL logic developed by myself and others a few years ago is strictly first-order, but it contains its own meta-language: it is able to describe its own propositions and reason about them, and even quantify over them, with complete syntactic freedom, without needing any kind of 'layering' discipline to maintain internal consistency. The propositions are fully-fledged genuine elements of the semantic universe, just like everythng else the logic is describing. (See http://www.ihmc.us/users/phayes/ikl/guide/guide.html ) The RDF semantics uses a simpler version of the same basic device to ensure consistency while allowing such things as classes that contain themselves (rdfs:Class is an element of itself, for example.) JB: The layering approach traces back to a paper by Edsger W. Dijkstra entitled "THE Machine" which suggests that operating systems should be constructed in layers: http://www.cs.virginia.edu/~zaher/classes/CS656/p341-dijkstra.pdf Further, Dijkstra points out that in a well-behaved system a layer passes data to an adjacent layer but does not dip into another's layer's data. Today, this approach is modified a bit, again for operating systems. Hierarchical structure is still used, but forward and reverse tunnels are established to steal data away from a layer using a higher (temporal) priority. One can argue that semantic and linguistic processing are types of operating systems, but I think of them more as applications running under an operating system. Still, a system that uses an ontology may use a number of different architectural approaches, and layering might be useful for some. I don't think we should ban them altogether. I imagine a sophisticated system would use a combination of layering, data passing and link types to allow a wide variety of data access. -John Bottoms > So, layering is not in fact necessary. I would argue that it is also not desirable. The world is *not* layered in this way, in fact. Language is as much part of the real world as architecture is, and words are just as real as houses. (Contrary to your assertion, below: words *are* objects.) Language is itself described in language just like anything else is: the word "word" describes words just as the word "house" describes houses. And we do in fact violate any kind of layering discipline whenever we talk about reference, because to even describe the idea of reference, we have to say what the referring word is, and what that word refers to, and so mention both 'layers' in one sentence. And when we talk about the business of defining reference itself, as I have just been doing in the previous sentence, we are actually using at least three layers, because this discourse itself is about the *relationship* between language and the world that it describes, which would be located in a higher "level". If you try to keep this kind of discussion separated into rigorously distinct layers of objects, descriptions and meta-descriptions, you will inevitably fail, or become hopelessly confused. Not because the ideas are hard to grasp, but because the layer metaphor is simply inadequate to the task of handling this kind of discussion. > > So, to sum up: strictly separated layers of description and meta-description are not in fact required, are artificial, and do not correspond to reality. This layering idea is neither correct nor useful. Abandoning it does not lead to paradoxes or to infinite loops: it just requires us to be a little careful when we make definitions, to check they are internally consistent. But this is a good idea, in any case. > > Hope this helps. > > Best wishes > > Pat > > > > On Apr 11, 2013, at 3:02 PM, Pavithra wrote: > >> Doug, >> >> I understand that "Thing" is used in an universal type and everything is a thing, until further defined. >> >> The word "house" is an English word that represent an object house, The word itself is not an object, it is a 5 character string ( which you call a thing) , that represents a building with rooms and doors and roof etc ( which is actually the thing.) >> >> Every word represents something in real world, based on the language.

I understand that it is a matter of semantics, and it has been defined and formalized that way. If we have to change it, we have to define a new class - language, and subclass - word , types as - noun, verb etc. But all the double usage ( as in string vs string ) of the same words with multiple context usage etc cause semantic problems. So I understand that we can not jump the guns make changes unless such issues have resolutions. >> >> Pavithra >> >> From: doug foxvog <doug@xxxxxxxxxx> >> To: Pavithra <pavithra_kenjige@xxxxxxxxx> >> Cc: "doug@xxxxxxxxxx" <doug@xxxxxxxxxx>; [ontolog-forum] <ontolog-forum@xxxxxxxxxxxxxxxx>; Pat Hayes <phayes@xxxxxxx> >> Sent: Thursday, April 11, 2013 4:38 PM >> Subject: Re: [ontolog-forum] Dennett on the Darwinism of Memes >> >> On Wed, April 10, 2013 18:04, Pavithra wrote: >>> Dr. Pat & Doug, >>> I remember these discussion and decisions about defining "Words are >>> things, just as numbers, patterns and other non-physical >>> things are.
