A platform-independent downloadable for finding constraint weightings and constraint rankings, and for calculating typological predictions in both serial and parallel versions of Optimality Theory and Harmonic Grammar.
On-line and batch learners for Harmonic Grammar implemented as R scripts, along with input files and other related materials.
Other software-related material:
Some information on how to use the various on-line learning algorithms implemented in Praat. See “Perceptron” at the above HG-R link for an implementation of the HG learners in R, which is *much* slower, but is also more flexible in some ways.
A website with information on software for web-based experiments being developed at UMass Amherst, and other resources for running experiments over the internet.
