In recent years, the theoretical foundations of informatics have been questioned. While no one really disputes the formal, logical foundations, many have noticed that there is more to the theory of writing programs than logics and algorithmic theory. One particular aspect of complex software has begun to emerge: its intrinsic semiotic nature.

The representation problem is deeply rooted in semiotics. Nothing can become a subject matter of computing unless it is first transformed into signs. The computer may be called a semiotic machine, and informatics may be viewed as a Technical Semiotics or Semiotic Engineering. Models are extremely important to computing. They are of semiotic nature. Hierarchies or other structures of systems are signs of signs, Graphic user interfaces burst with signs.

Informatics deals with algorithmic semioses. This notion entails a contradiction in adjecto: Signs are pragmatically interpreted, semantically defined, and syntactically processed. But computing applies to the syntactic dimension only. Therefore, signs have to be reduced to their syntactic dimension in order to enter an algorithmic semiosis. The seminar addressed this contradiction.

Our intent is to bring together people both from informatics and semiotics. We hope for contributions and discussion that identify differences in theoretical assumptions and practical conclusions, and go on to formulate detailed questions for research agenda.

Details of the workshop are open to the participants. Questions to be asked could include the following:

  • In what sense does semiotics belong to the fundamentals of a theory of informatics?
  • What are the semiotic foundations of informatics?
  • What happens to sign processes when they are submitted to computers?
  • What can interface designers learn form semiotics?
  • What are repercussions of informatics on semiotic research?
  • In what sense can we view the computer as a medium?
  • Which consequences foes this have for software design?
  • How does interactivity reflect the semiotic condition of informatics?
  • Does the Physical Symbol Systems Hypothesis have a fruitful semiotic interpretation?
  • Is the semiotic foundation of human cognitive processes the same as that of information processing?
  • Can we derive, from this foundation, improved computational models?


In der Reihe Dagstuhl Reports werden alle Dagstuhl-Seminare und Dagstuhl-Perspektiven-Workshops dokumentiert. Die Organisatoren stellen zusammen mit dem Collector des Seminars einen Bericht zusammen, der die Beiträge der Autoren zusammenfasst und um eine Zusammenfassung ergänzt.

Bitte informieren Sie uns, wenn eine Veröffentlichung ausgehend von Ihrem Seminar entsteht. Derartige Veröffentlichungen werden von uns in der Rubrik Dagstuhl's Impact separat aufgelistet  und im Erdgeschoss der Bibliothek präsentiert.


Es besteht weiterhin die Möglichkeit, eine umfassende Kollektion begutachteter Arbeiten in der Reihe Dagstuhl Follow-Ups zu publizieren.
