"Information" and "Knowledge" - On the Semantic Transformation <strong>of</strong> Two Central Terms<br />

demographic time bomb (Virilio, 2000, p. 123) and po<strong>in</strong>ts accord<strong>in</strong>gly to their share <strong>in</strong><br />

provok<strong>in</strong>g an apocalyptic end to human civilisation.<br />

Those who want to understand the <strong>in</strong>flationary use and enormous force <strong>of</strong> this second<br />

version <strong>of</strong> the term "<strong>in</strong>formation" have to become familiar with those different mean<strong>in</strong>gs<br />

which it only acquired <strong>in</strong> the context <strong>of</strong> the reception <strong>of</strong> the American theory <strong>of</strong><br />

<strong>in</strong>formation, <strong>in</strong>formation and communication science and <strong>in</strong>formatics. The English word<br />

("<strong>in</strong>formation") was placed alongside the Lat<strong>in</strong> word ("<strong>in</strong>formatio"). In these research<br />

fields <strong>in</strong>formation is naturally the central term, which is <strong>in</strong> fact signalled through the<br />

names <strong>of</strong> the discipl<strong>in</strong>es. However, its mean<strong>in</strong>g is decisively different from the ones<br />

sketched <strong>in</strong> here. "Information" here is someth<strong>in</strong>g that is derived from transmitted data,<br />

signals or signal consequences.<br />

How did it come to this difference <strong>in</strong> mean<strong>in</strong>g? In <strong>in</strong>formation theory the term<br />

"<strong>in</strong>formation" is def<strong>in</strong>ed purely formally. The basis for this is the mathematical theory <strong>of</strong><br />

the transmission <strong>of</strong> <strong>in</strong>formation from Claude Elwood Shannon and Warren Weaver<br />

(1978): for them, <strong>in</strong>formation becomes a mathematically describable technical term<br />

which deviates considerably from general use because the "sense" and "mean<strong>in</strong>g" <strong>of</strong> the<br />

<strong>in</strong>formation is not important. 4 With its help attempts are made to explore empirically the<br />

quantitative regularities <strong>of</strong> the transmission <strong>of</strong> <strong>in</strong>formation and to show them <strong>in</strong> formal<br />

theory. This deals, for example, with the order<strong>in</strong>g characteristics <strong>of</strong> the signals, channels<br />

and their capacity, the efficiency <strong>of</strong> encod<strong>in</strong>g, the calculation <strong>of</strong> <strong>in</strong>formation quantities<br />

or <strong>of</strong> transmission faults, <strong>in</strong> other words, with the fundamental conditions <strong>of</strong> productive<br />

<strong>in</strong>formation work, which is understood to be "work<strong>in</strong>g out, process<strong>in</strong>g and manag<strong>in</strong>g<br />

items <strong>of</strong> <strong>in</strong>formation" (Kuhlen, 1991, p. 334). These circumstances are extremely important<br />

for pedagogues, because learn<strong>in</strong>g is primarily a matter <strong>of</strong> understand<strong>in</strong>g the "mean<strong>in</strong>g"<br />

<strong>of</strong> <strong>in</strong>formation.<br />

The <strong>in</strong>formation theory paradigm was taken over by <strong>in</strong>formatics, the science <strong>of</strong> automatic<br />

knowledge process<strong>in</strong>g. Here it is important above all to enable the above-mentioned<br />

<strong>in</strong>formation work technically, <strong>in</strong> other words, for example, search<strong>in</strong>g, f<strong>in</strong>d<strong>in</strong>g, record<strong>in</strong>g,<br />

stor<strong>in</strong>g, retriev<strong>in</strong>g, transmitt<strong>in</strong>g, convert<strong>in</strong>g and arrang<strong>in</strong>g items <strong>of</strong> <strong>in</strong>formation. In order<br />

to be able to develop the appropriate technologies, the <strong>in</strong>formation was subdivided<br />

empirically <strong>in</strong>to its components or elements. These are referred to as "signals" and "data".<br />

Signals are signs that are given through technical means, sent over a distance and whose<br />

mean<strong>in</strong>g is agreed beforehand by the sender and the addressee. In cybernetics this is an<br />

energy-laden physical process. An attempt is made above all to detect and reconstruct<br />

the formal and technical sequences <strong>of</strong> this process. The technically skilled <strong>in</strong>terpret a<br />

series <strong>of</strong> signals, which br<strong>in</strong>g about someth<strong>in</strong>g def<strong>in</strong>ite <strong>in</strong> def<strong>in</strong>ed situations, as modules<br />

for the creation <strong>of</strong> <strong>in</strong>formation. The signals that come from the letters <strong>of</strong> the text can<br />

take on the character <strong>of</strong> images through multimedia and simulations, through which a<br />

new tape <strong>of</strong> encod<strong>in</strong>g <strong>of</strong> <strong>in</strong>formation is created. This consists <strong>of</strong> a type <strong>of</strong> "pictorial<br />

4 This research discipl<strong>in</strong>e was able, however, to use the help <strong>of</strong> empirical means to say someth<strong>in</strong>g about the<br />

"content" <strong>of</strong> <strong>in</strong>formation. it measures the <strong>in</strong>formation content with the degree <strong>of</strong> uncerta<strong>in</strong>ty that is caused by<br />

the lack <strong>of</strong> the <strong>in</strong>formation. The value <strong>of</strong> an item <strong>of</strong> <strong>in</strong>formation is determ<strong>in</strong>ed by the significance that it has<br />

for the addressee. It is great, if the <strong>in</strong>formation is completely unexpected, and low if the content is more or less<br />

known beforehand. In other words, this is simply a formal characterisation <strong>of</strong> the content <strong>of</strong> the <strong>in</strong>formation.<br />
