Short Summary of the Workshop

The aim of this workshop is to investigate how Statistical Physics can help elucidating two long-standing linguistic questions: How does language change proceed in time, and what triggers syntactic change, in particular what is the role of prosody in syntatic change.

Empirical data will be provided by the recent history of the pronominal clitic system of Portuguese. The Tycho Brahe Parsed Corpus of Historical Portuguese (http://www.ime.usp.br/~tycho/) will be intensively exploited for this purpose.

The theoretical frameworks of the discussion are the Generative Grammar approach to language and the Thermodynamical Formalism from Statistical Physics. The former includes the Minimalist version of the Theory of Principles and Parameters and Optimality Theory. The latter has been used in recent years as a basis for models of pattern identification, and for understanding critical phenomena in complex systems. In the present discussion, the Thermodynamical Formalism provides a model for the interaction between prosody and syntax in language acquisition.

The topics to be discussed during the workshop included:

Laboratory Sessions

Besides the talks and debates scheduled above, there were permanent laboratory sessions, in which available samples of empirical data were extensively analyzed. Moreover, the effort of developing pertinent linguistic, mathematical and statistical models and tools for the issues raised by the project were continued in these sessions. Laboratory sessions included:

The Sotaq processor, the Tycho Brahe Corpus of Historical Portuguese, and a collection of papers related to the topics of the meeting are available at the web site of the project. Samples of acoustic data will be available during the meeting.

 

Sponsors

The meeting has the sponsorship of the Associação Portuguesa de Linguística and of the Complexo interdisciplinar of the University of Lisbon and is supported by the Fundação para a Ciência e a Tecnologia (FCT) (Portugal).

The workshop will take place at the Complexo interdisciplinar of the University of Lisbon as an activity of the Mathematical Physics group. It is a satellite activity of ZiF's project The Sciences of Complexity and is part of the Fapesp's thematic project Rhythmic Patterns, Parameter Setting and Language Change.
