Computational Semiotics is a quite new field of research, which emerged from advanced studies on artificial intelligence and intelligent systems. It is an alternative to the mainstream approaches - those based either on cognitivism or on biologically inspired techniques. Instead, Computational Semiotics seeks its inspiration on semiotics, a tradition on the philosophy of mind dealing with the concepts of representation and communication from a more technical perspective. The whole story besides this new field of research is usually unknown from many researchers working on the field of intelligent systems. This story started during the 1970's, where two main precursors first published works relating semiotics to intelligent systems development, almost at the same time in Russia and in the U.S. These pioneering studies were performed by Dmitri Pospelov in Russia and Eugene Pendergraft in U.S. Despite promising research results, for diverse reasons they stayed ignored from the mainstream in Artificial Intelligence for about 25 years. However, around 1995 they were rediscovered, motivating the development of this new paradigm of research. The goal of this paper is to briefly review the main contributions in this area. © 2005 IEEE.2005 393398Noth, W., (1995) Handbook of Semiotics (Advances in Semiotics), , Indiana University PressPospelov, D.A., Principles of situational control (1971) Engineering Cybernetics, (2), pp. 216-222. , MoscowPospelov, D.A., (1986) Situational Control: Theory and Practice, , unpublished translation from the original in russian, edited by Nauka Publishers, MoscowPendergraft, E.P., (1964) Self-organizing Linguistic Sytems Linguistic Research Seminar, , Santa Monica, CaliforniaPendergraft, E.P., The future's voice - Intelligence based on pragmatic logic (1993) Technical Report, , Creative Intelligence Incorporated, DRAFT (FATE), Jasper, EUA, JunePospelov, D.A., Zhelezov, Zh.Y., On a class of large systems (1970) Engineering Cybernetics, (2), pp. 243-246. , MoscowPospelov, D.A., Yeimov, Ye.I., Semiotic models in planning problems of artificial intellect systems (1977) Engineering Cybernetics, (5), pp. 37-43. , MoscowOsipov, G.S., Origins of applied semiotics (2000) ECAI 2000, 14th European Conference on Artificial IntelligenceSulosky, M.F., Semiotics situational control - JSM-type reasoning and Q-analysis, intelligent systems: A semiotic perspective (1996) Proceedings of the 1996 International Multidisciplinary Conference, Vol. II: Applied Semiotics, 2. , Gaithersburg, MarylandWaterman, D.A., (1986) A Guide to Expert Systems, , Addison Wesley Publishing Company(1997) White Paper, , A Skeleton Autognome, Autognomics Corp., EUA(2001) Autognomics Technology - Brief Overview of Autognomics, , Autognomics Corp., EUAAlbus, J.S., Outline for a theory of intelligence (1991) IEEE Transactions on System, Man and Cybernetics, 21 (3). , May/JuneAlbus, J.S., Meystel, A.M., (2001) Engineering of Mind: An Introduction to the Science of Intelligent Systems, , John Wiley & SonsISBN: 0471438545Meystel, A.M., Albus, J.S., (2001) Intelligent Systems: Architecture, Design, Control, , Wiley-InterscienceISBN: 0471193747Albus, J.S., The NIST Real-time Control System (RCS): An approach to intelligent system research (1997) J.
