Session Summary
The session summary empathizes • organizing, • finding and • managing information • by meaning - semantically.• semantic relationships
![Page 3: Semantic Information Relationships April 25, 2008 Cecil Somerton.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649d245503460f949fa874/html5/thumbnails/3.jpg)
Learning Objective
• A look at semantics• Relationships between semantics and information• A little Information Architecture• Viewpoints and Views• Meaning Exposed• Relationship to other Architectures• Relationship to Business Outcomes• Semantic Relationships
![Page 4: Semantic Information Relationships April 25, 2008 Cecil Somerton.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649d245503460f949fa874/html5/thumbnails/4.jpg)
Semantics – What do we mean?
• the study of meanings • the study of meaning in communication• the study of meaning in language. See also
formal semantics, pragmatics, syntax.• the relation between the signs and the
objects to which they apply.
![Page 5: Semantic Information Relationships April 25, 2008 Cecil Somerton.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649d245503460f949fa874/html5/thumbnails/5.jpg)
Meaning
• Etymology:• Middle English menen, from Old English mænan; akin
to Old High German meinen to have in mind, Old Church Slavic měniti to mention
• to have in the mind as a purpose• to serve or intend to convey, show, or indicate

Sharing Meaning
![Page 7: Semantic Information Relationships April 25, 2008 Cecil Somerton.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649d245503460f949fa874/html5/thumbnails/7.jpg)
Syntax
• the way in which linguistic elements (as words) are put together to form constituents (as phrases or clauses)
• Syntax studies the interrelation of the signs, without regard to meaning.• "Colorless green ideas sleep furiously."
• A systematic, orderly arrangement.
![Page 8: Semantic Information Relationships April 25, 2008 Cecil Somerton.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649d245503460f949fa874/html5/thumbnails/8.jpg)
Sign - Form
![Page 9: Semantic Information Relationships April 25, 2008 Cecil Somerton.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649d245503460f949fa874/html5/thumbnails/9.jpg)
Sign - Form
• a fundamental linguistic unit that designates an object or relation or has a purely syntactic function
• "something that stands for something else, to someone in some capacity"
• all of the ways in which information can be communicated
![Page 10: Semantic Information Relationships April 25, 2008 Cecil Somerton.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649d245503460f949fa874/html5/thumbnails/10.jpg)
An Aside InformationInformation - noun 1: the communication or reception of knowledge or
intelligence2 a (1): knowledge obtained from investigation, study,
or instruction (2): intelligence, news (3): facts, datab: the attribute inherent in and communicated by one of two or more alternative sequences or arrangements of something that produce specific effectsc (1): a signal or character (as in a communication system or computer) representing data (2): something (as a message, experimental data, or a picture) which justifies change in a construct (as a plan or theory) that represents physical or mental experience or another construct…

Pragmatics
• the study of language use in particular situations
• the relation between the sign system and its human user.
• the study of relations between language and context.

John Sowa Explains• From: John F. Sowa [mailto:[email protected]]• > Sent: 30 August 2007 03:55• > To: Barker, Sean (UK)
• I'm glad that you found the 3-way distinction helpful, but I want to • > emphasize three very important points:• > • > 1. It is possible to have syntax by itself without semantics or• > pragmatics. That would be a purely uninterrupted notation• > with no meaning other than to create strings of symbols.• > • > 2. It is possible to have syntax and semantics without pragmatics.• > That would be a pure description of something, such as a list• > of observed data with no indication of what to do.• > • > 3. For any practical language of any use in engineering, it is• > essential to have all three: syntax, semantics, and pragmatics.………• > It's impossible to say anything without syntax. It's impossible to • > refer to anything without semantics. And it's impossible to do • > anything pragmatically without being able to make statements• > (syntax) that refer to something (semantics).• > • > John

Semiotics
Charles Sanders Peirce 1839 – 1914• Semantics: Relation between signs and the
things they refer to, their denotata. • Syntactics: Relation of signs to each other in
formal structures. • Pragmatics: Relation of signs to their impacts
on those who use them.
![Page 15: Semantic Information Relationships April 25, 2008 Cecil Somerton.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649d245503460f949fa874/html5/thumbnails/15.jpg)
Semiotics
Charles Morris (1903 – 1979)Concerned with the study of the science of
signs, which he called semiotic;Distinguished 3 branches of semiotics:
syntactics (or syntax), which studies the formal relation among different signs; semantics, the study of the relation between the signs and the objects they denote; and pragmatics, the study of the relation of signs to their interpreters, i.e. people.

Overstating the Obvious
The Belgian surrealist René Magritte (1898-1967) painted La Trahison des Images (The Treachery of Images) in 1936.

A Shout of RecognitionUnderstanding is paramount – “What I mean is … “
The philosopher John Locke pointed out three centuries ago that; the achievement of human knowledge is often hampered by the use of words without fixed signification.
Timothy Findlay’s fictional Irish essayist Nicholas Fagan wrote, “the space between the perceiver and the thing perceived can … be closed with a shout of recognition”

Put Another Way
“Any meaningful exchange of utterances depends upon the prior existence
of an agreed upon set of semantic and syntactic rules.”
The recipients of the utterances must use only these rules to interpret the received utterances,
if it is to mean the same as that which was meant by the utterer

Structural Specification
• Contextualizes business concepts and their relationships in consistent, complete and repeatable expressions.
• Generally deals with the standardization, rules and methodology for optimizing concept specifications.
• Optimization as determined by the extent of the union of the set of semantic, syntactic and pragmatics used to produce the concept specification.

Structural Composition
• Information composition generally extends the pragmatics of basic information specification to include business intent, authority, goals and objectives.
• Addresses the construction and standardization of optimized information patterns, products used by a business that extends the value proposition associated with information specification.
• Information products are represented by such structures as models, or business documents/patterns (information instruments such as cheques, invoices, reports, statistics, etc).

Business Intelligence
• Business intelligence is the use of an organization's disparate data to provide meaningful information and analysis to employees, customers, suppliers, and partners for more effective decision making.

Structural Integration
• Includes mechanisms for semantic rationalization and alignment of information structures.
• Leverages and integrates existing information structures (concept mapping across models and terminology, concept system integration)
• Develops ontological commitments within and across communities to facilitate information interchange. (ontological comparisons, sufficient equivalency determinations etc.)

Ontology (1): What it is
• An ontology is an explicit specification of a conceptualization (Gruber 1994)
• An ontology is a formal specification of a shared conceptualization (Borst 1997)
Ontological commitment:• Stakeholders using conceptual models should have
a shared understanding of the modeling constructs to create a common understanding of the Universe of Discourse at hand.
