Abstract

Semiotics is an innovative science that has latterly entered the field of contemporary research. This knowledge application has become more or less common in urban planning, although gradually and not directly. Various urban phenomena tend to be hidden based on their characteristics, and only their effects can be studied in the city, so semiotics can be an efficient and accurate mechanism to generate qualitative data from cities. This article consists of three sections; First, with an initial review of the fundamental concepts and definitions of semiotics, the SIGN is defined and then based on the theoretical foundations of Saussure's concepts, semiotics indicators are categorized. Next, the prototypes of semiotics from the point of view of Umberto Eco, which is one of the most famous categorizations done in this regard, will be studied. Subsequently, the following classifications will be considered in this article: - Biological semiotics - Ecological semiotics - Computer Semiotics - Social semiotics - Cultural semiotics - Visual semiotics - Visual semiotics In the last section, for each of the seven types of semiotics explained, first, a definition and second Saussure's concepts of it will be analyzed and finally the interpretation of that class of semiotics in urban planning, or in other words, the application of each type of semiotics in urban planning will be discussed.
