Title: Complexity phenomena in linguistics
Room: Informatics East 122
Abstract: Throughout history language sciences have been dealing with numerous phenomena that are either inherently complex/dynamic systems, or which display characteristic properties of such systems. Within an individual, one can point to perceptual dynamics and categorisation in speech, the emergence of phonological templates, or word and sentence processing; across society, think variations and typology, the rise of new grammatical constructions, semantic bleaching, language evolution in general, and the spread and competition of both individual expressions, and entire languages.
A handful of language phenomena will be depicted which have been known to exhibit such properties as hysteresis, phase transition, bifurcation, attractor states, or power law distribution. The multifaceted dynamism and complexity will also be discussed of the process of language acquisition, highlighting the importance of adopting designs with different timescales in order to trace language development as a process of change over time, of the utility of time-series analyses, and of the ability to determine optimal temporal integration windows, e.g. in analyses of dynamic motifs in human communication.
The talk will conclude with a presentation of the results of two small-scale projects applying social network analysis (SNA) to language phenomena. One involved exploring the social propagation of neologisms in a microblogging service, the other investigating the impact of peer influence on second-language learning outcomes. Using the methods of complexity science, from local, low-level interactions between individuals verbally communicating with one another we can describe the processes underlying the emergence of more global systemic order and dynamics. Hypotheses will be presented which account for the novel findings.
