%A Christophe Menant %J Entropy ISSN 1099-4300 C 2003 by MDPI www.mdpi.org/entropy %T Information and Meaning %X We propose here to clarify some of the relations existing between information and meaning by showing how meaningful information can be generated by a system submitted to a constraint. We build up definitions and properties for meaningful information, a meaning generator system and the domain of efficiency of a meaning (to cover cases of meaningful information transmission). Basic notions of information processing are used. %D 2003 %K Meaning, information, system, constraint, generation, efficiency %L cogprints3694 %V Entrop
