The present article is framed within the biosemiotic glossary project as a way to address common terminology within biosemiotic research. The glossary integrates the view of the members of the biosemiotic community through a standard survey and a literature review. The concept of ‘semiotic threshold’ was first introduced by Umberto Eco, defining it as a boundary between semiotic and non-semiotic areas. We review here the concept of ‘semiotic threshold’, first describing its denotation within semiotics via an examination on the history of the concept, its synonyms, antonyms, etymology, usage in other languages and context in which it is used. Then we present a general overview of the survey among researchers, analyzing the difference in responses for the concept of ‘lower semiotic threshold’ and related concepts. From the answers we also review the difference between the general usage of ‘semiotic threshold’ versus its specific use within biosemiotics, and attempt to make a general synthesis of the concept taking into account what we have learned from the survey and the literature review.

The article gives a historical overview of the institutional development of semiotics in Estonia during two centuries, and describes briefly its current status. The key characteristics of semiotics in Estonia include: (1) seminal role of two world-level classics of semiotics from the University of Tartu, Juri Lotman and Jakob von Uexkull; (2) the impact of Tartu–Moscow school of semiotics, with a series of summer schools in Kaariku in 1960s and the establishment of semiotic study of culture; (3) the publication of the international journal Sign Systems Studies, since 1964; (4) the development of biosemiotics, notably together with colleagues from Copenhagen; (5) teaching semiotics as a major in bachelor, master, and doctoral programs in the University of Tartu, since 1994; (6) a plurality of institutions — in addition to the Department of Semiotics in the University of Tartu, several supporting semiotic institutions have been established since 1990s; and (7) a wide scope of research in various branches of semiotics, including theoretical studies, empirical studies, and applied semiotics projects on governmental and other request.
