Workshop on Complexity in Language – Day 2 (report)

I could not follow the whole second day of the Workshop on Complexity in Language (see previous post), but here is what I heard in the morning.

Salikoko Mufwene talked about the emergence of complexity, which he sees as a self-organization process : we don’t plan the way we are going to speak.

He adopts a relativistic perspective speaking of a multi-agent system and asking if the agents are really agentive or if there are triggers of particular behaviors. He likes to consider language as a technology that evolved. At the end of the talk he also tackled the notion …

Workshop on Complexity in Language - Day 1 (report)

I attended yesterday the first day of a workshop organized by Salikoko Mufwene and held at the ENS Lyon. This “Workshop on Complexity in Language: Developmental and Evolutionary Perspectives” lasts two days: HTML version of the program.

Here is my personal report on what I heard during the first day and on what I found interesting.

Complexity and complexity science

First of all, William S.-Y. Wang referred to Herbert Simon and Melanie Mitchell in particular to define complexity, two approaches that I described on this blog.

Tom Schoenemann talked about the increasing richness, subtlety and complexity of hominin conceptual …

Simon, Gell-Mann and Lloyd on complex systems

Definition

Herbert A. Simon is one of the first who tried to formalize the notion of a complex system: * H. A. Simon, “The Architecture of Complexity”, Proceedings of the American Philosophical Society, vol. 106, iss. 6, pp. 467-482, 1962.

First of all, here is how he defines it:

« Roughly, by a complex system I mean one made up of a large number of parts that interact in a nonsimple way. In such systems, the whole is more than the sum of the parts, not in an ultimate, metaphysical sense, but in the important pragmatic sense that, given the properties of …

Melanie Mitchell: defining and measuring complexity

I just read with peculiar attention the seventh chapter of Complexity: A Guided Tour, by Melanie Mitchell (Defining and measuring complexity, pages 94 to 111). She works with the Santa Fe Institute which is a major institution regarding research on complex systems. She gives a convincing outlook of this field. Still, I did not read anything on the question of language as a complex adaptive system, although there are researchers who focus on this topic (e.g. in Santa Fe).

According to her, there are different sciences of complexity with different notions of what complexity means. The notion of complexity …
