Workshop on Computing and Phonology

A small workshop on computational aspects of phonology is held at the University of Groningen (RUG), the Netherlands, on December 8, 2006. The workshop is open to anyone, but we kindly ask you to register not later than December 4. Should you have any question, please feel free to contact Tamás Bíró at birot @

Scaling Minimal Generalization
In this study, we model the phonotactics using minimal generalization, a stochastic rule-based system proposed by Albright and Hayes (2003), who used this system successfully on learning the past tense in English. Their system generates rules that try to generalize over the phonetic features of the input (in our case, the CELEX database). These rules are hypotheses which might prove wrong in other parts of the input; hence they are 'stochastic'. This algorithm maintains the explicitness of rule-based systems, but adds an element of stochastic comparison. The results from Albright and Hayes also suggest that the model captures some aspects of cognitive representation faithfully.
However, when we apply this methodology to the problem of phonotactics, it does not immediately generalise well. It accepted well-formed examples well, but was ill-equipped to reject strings as ill formed. We therefore propose improvements to the original algorithm, first, to force it to greater discrimination, and second, to take into account implicit negative information as well. The improved algorithm reduces the number of rules by a factor 5, and thus improves the transparency of the output. It also cuts the number of errors (both false positives and false negatives) in half compared to the original algorithm.
