Semiotics is the systematic study of sign processes and the communication of meaning. In semiotics, a sign is defined as anything that communicates intentional and unintentional meaning or feelings to the sign's interpreter.
Biosemiotics is a field of semiotics and biology that studies the prelinguistic meaning-making, biological interpretation processes, production of signs and codes and communication processes in the biological realm.
Zoosemiotics is the semiotic study of the use of signs among animals, more precisely the study of semiosis among animals, i.e. the study of how something comes to function as a sign to some animal. It is the study of animal forms of knowing.
Jakob Johann Freiherr von Uexküll was a Baltic German biologist who worked in the fields of muscular physiology and animal behaviour studies and was an influence on the cybernetics of life. However, his most notable contribution is the notion of Umwelt, used by semiotician Thomas Sebeok and philosopher Martin Heidegger. His works established biosemiotics as a field of research.
In the semiotic theories of Jakob von Uexküll and Thomas Sebeok, umwelt is the "biological foundations that lie at the very center of the study of both communication and signification in the human [and non-human] animal". The term is usually translated as "self-centered world". Uexküll theorised that organisms can have different umwelten, even though they share the same environment. The term umwelt, together with companion terms Umgebung and Innenwelt, have special relevance for cognitive philosophers, roboticists and cyberneticians because they offer a potential solution to the conundrum of the infinite regress of the Cartesian Theater.
Thomas Albert Sebeok was a Hungarian-born American polymath, semiotician, and linguist. As one of the founders of the biosemiotics field, he studied non-human and cross-species signaling and communication. He is also known for his work in the development of long-time nuclear waste warning messages, in which he worked with the Human Interference Task Force to create methods for keeping the inhabitants of Earth away from buried nuclear waste that will still be hazardous 10,000 or more years in the future.
Sign Systems Studies is a peer-reviewed academic journal on semiotics edited at the Department of Semiotics of the University of Tartu and published by the University of Tartu Press. It is the oldest periodical in the field. It was initially published in Russian and since 1998 in English with Russian and Estonian language abstracts. The journal was established by Juri Lotman as Trudy po Znakovym Sistemam in 1964. Since 1998 it has been edited by Kalevi Kull, Mihhail Lotman, and Peeter Torop. Since 2022, Ott Puumeister leads the editorial team. The journal is available online from the Philosophy Documentation Center, indexed by WoS and Scopus, and starting 2012 also on an open access platform.
John Deely was an American philosopher and semiotician. He was a professor of philosophy at Saint Vincent College and Seminary in Latrobe, Pennsylvania. Prior to this, he held the Rudman Chair of Graduate Philosophy at the Center for Thomistic Studies, located at the University of St. Thomas (Houston).
Claus Emmeche is a Danish theoretical biologist and philosopher, one of founders of contemporary biosemiotics. He is associate professor at the University of Copenhagen, and is head of the Center for the Philosophy of Nature and Science Studies at the Faculty of Science.
Karl Kuno Thure Freiherr von Uexküll was a German scholar of psychosomatic medicine and biosemiotics. He developed the approach of his father, Jakob von Uexküll, in the study of living systems and applied it in medicine.
Martin Krampen was a leading German semiotician, semiotics Professor in Göttingen.
Phytosemiotics is a branch of biosemiotics that studies the sign processes in plants, or more broadly, the vegetative semiosis. Vegetative semiosis is a type of sign processes that occurs at cellular and tissue level, including cellular recognition, plant perception, plant signal transduction, intercellular communication, immunological processes, etc.
Giorgio Prodi was an Italian medical scientist, oncologist and semiotician.
The International Society for Biosemiotic Studies (ISBS) is an academic society for the researchers in semiotic biology. The Society was established in 2005. Its official journal is Biosemiotics, published by Springer and launched in 2008.
Jesper Hoffmeyer was a professor at the University of Copenhagen Institute of Biology, and a leading figure in the emerging field of biosemiotics. He was the president of the International Society for Biosemiotic Studies (ISBS) from 2005 to 2015, co-editor of the journal Biosemiotics and the Springer Book series in Biosemiotics. He authored the books Biosemiotics: An Examination into the Signs of Life and the Life of Signs and Signs of Meaning in the Universe and edited A Legacy for Living Systems: Gregory Bateson as Precursor to Biosemiotics.
Jakob von Uexküll Centre is an Estonia-based organisation for the work with the legacy of biologist, philosopher and semiotician Jakob von Uexküll. The Centre owns the major archive of his works in the world.
Ecosemiotics is a branch of semiotics in its intersection with human ecology, ecological anthropology and ecocriticism. It studies sign processes in culture, which relate to other living beings, communities, and landscapes. Ecosemiotics also deals with sign-mediated aspects of ecosystems.
The following outline is provided as an overview of and topical guide to semiotics:
Copenhagen–Tartu school of biosemiotics is a loose network of scholars working within the discipline of biosemiotics at the University of Tartu and the University of Copenhagen.
Polar semiotics is a concept in the field of semiotics, which is the science of signs.
