I like this very much because I think that almost all the different views on this subject expressed here fit into the model.    Some might disagree about some of the details, of course.

A belated contribution on “data” and “datum”.  These are one or more items of information taken as given for performing a task or solving a problem.  So what do we mean by “item” and “information”?

Appalled by the sloppy terminology in the information systems field, I wrote a book (Information, 1973), which used Peircian ideas among many others to show how the existing literature sets some excellent examples.

That book is out of print. There would have been a second edition but a burglar took my computer and its backup disc, thus diverting my energy to a book on semantics.  The main argument was as follows.

            Computer science has a sound basis in the formal sciences but it is too narrow for a science of information systems, which is failing to develop because the IS community uses language so imprecisely, talking, for example, of  “Data”, “information”, “meaning”, which have multitudes of precise meanings.  One hears the chemical engineering metaphor about a series of mystical fluids. Thus: distil data to obtain information, which you distil to obtain knowledge and meaning.  I joked one day that someone would distil knowledge to obtain wisdom only to read that proposition in an article a leading accountancy journal and in a pamphlet thrust into my hand by a member of a religious sect!  “DIKW” has just yielded 159,000 hits on Google!  I could scream.

I introduced a ‘semiotic framework’ to focus on six ways of understanding different aspects of signs.  Each limited range of properties of signs builds on the earlier ones.  Within each level, ‘’data”, “information”, “meaning”, “knowledge” etc. have at least one operationally precise meaning, often several. There’s not space enough to give examples for each level.

Physical level – Just he physical properties of marks treated as information; the material and energy employed in operations on them, whether performed by machines or people.  All economic questions about information systems efficiency end up here.  (Physics, engineering, ergonomics)

Empiric level – The statistical/probabilistic properties of streams of sign-tokens: the domain of Shannon’s work.

Syntactic level – The structures built of sign-types and the operations that may be performed on them: the formal sciences and most of computer science (eg: Carnap and Bar Hillel on info.).

LEVELS ABOVE - THE TECHNICAL BASIS OF ANY INFO SYSTEM

LEVELS BELOW ARE INTRINSICALLY HUMAN AND SOCIAL

Semantic level – The nature and properties of the ‘stands for’ relationship between a sign-types and some thing(s) in the real world (!!!???).  (Philosophy and semiotics have contributed most here.)

Pragmatic level – The properties of sign-tokens that explicitly or implicitly express the intentions of their users.  (Language theory, philosophy, ethnomethodology, semiotics …)

Social level – The changes to attitudes and norms resulting from the interpretation of sign-tokens; these effects account for the positive or negative value of information.  (anthropology, social psychology, jurisprudence etc.)

No organisational information system can function well unless it does so on ALL those levels, a fact worth considering when ca. 25% of IS projects fail totally and ca. 50% fail in major respects.  My industrial experience suggested that we neglect the social levels; hence my research on ‘real world’ semantics and systems of social norms.
