Azamat thanks a lot for the interesting and detailed exposition below, from which I learn Maybe because I have studied with a leading semiologist ( Umberto Eco), but I would argue that what you refer to in parts of your definition below woudl be best called semiotics (science of signes and symbols) and not semantics. http://en.wikipedia.org/wiki/Semiotics To me semantics is the meaning of words, and semiotis is the meaning of non verbal communication, ie signs and symbols Please correct me where I am wrong, Paola Di Maio > Ken, > Essentially determining the nature of meaning (and significance), this > matter is the core issue not only for a unified computing ontology but > also for the machine processed semantics, the key element of the > semantic web. For signs (as the words of different languages) must be > related to concepts and ontological entities only by a many-to-one > relationship: from the words of natural languages (or the symbols of > formal ontology languages) to the concepts of the mind (the constructs > of knowledge machines) to the categories of ontology (the kinds of > things in the world). As an example, consider the class of > relationship, which can expressed by as many names as ‘connection’, > ‘association’, ‘link’, ‘reference’, ‘regard’, ‘tie’, ‘bond’; or > indicated by as many verbs as ‘to relate’, ‘associate’, link’, ‘link > up’, ‘connect’, ‘tie-in’, ‘colligate’, ‘refer’, pertain’, ‘concern’, > ‘bear on’, etc. Or, take the class of events expressed by as many > words as ‘happening’, ‘occurrence’, ‘occurrent’, ‘contingency’, > ‘outcome’, ‘effect’, ‘issue’, ‘upshot’, ‘result’, etc. For instance, > the process (event) of fire is that significance which the name 'fire' > has when it denotes the natural phenomenon. There is a plenty of > natural languages using their specific signs for this process, > nevertheless having always the same signification, since the concept > of fire is the same and the human experience is the same, regardless > of its numerous expressions in different natural or artificial > languages: 'fire', 'Feuer', 'ogon', etc.. > > So, semantic system may be constructed as a formal semantics or as a > more comprehensive and consistent, real world semantics; namely: > > ** > > *Formal Semantic System = sign (symbol) system (the SW languages, XML, > RDF, OWL) + axioms (mathematical or formal logical) + designation > rules (the semantic function from the set of language expressions into > the collection of constructs)* > > *Real Semantic System = sign (symbol) system + axioms (ontological, > mathematical, formal logical) + designation rules + semantic > assumptions (the reference function from constructs to real objects > cum the representation function from constructs to the state spaces of > the world) (ontological entities).* > > Thus, unlike the formal Semantic Web, the real Semantic Web includes > the correspondence (reification) rules from constructs to real world > entities (semantic assumptions), which parallels the semantic systems > of natural and social sciences. > > As a consequence, the Real Semantic Web (or the world wide intelligent > Web) as the pinnacle of ontological semantic technology involves a > grand trio of knowledge domains making the Knowledge Trinity: > > 1.

Semantics is aimed to provide a > general theory of meaning relations between signs, constructs and > things, assigning signification to syntactic structures and meanings > to conceptual structures. So, semantics integrates the totality of > signs, signals or symbols, the domain of knowledge, and the universe > of ontological entities and relationships into a comprehensive > knowledge and reasoning context (a unified ontology framework), > serving as the world modeling framework for all sorts of emerging > intellectual information and communications technologies. > > Azamat Abdoullaev > http://www.eis.com.cy > ----- Original Message ----- > From: "Ken Ewell" <mitioke@readware.com <mailto:mitioke@readware.com>> > To: "ONTAC-WG General Discussion" <ontac-forum@colab.cim3.net > <mailto:ontac-forum@colab.cim3.net>> > Sent: Monday, May 22, 2006 7:26 AM > Subject: Re: [ontac-forum] What should be in an upper-level ontology > > > JS> Words must be related to ontologies, but that mapping is a complex > > many-to-many [or one?] relationship between the words of any natural > > language and the categories of an ontology. > > > > No doubt.
