This is an archive of the work I was conducting while still pursuing a PhD in Computer Science. The code directory has both the OCaml implementation of PHOCUS, which is described in the publications listed here, and an unfinished Python port. The Python port was nearly complete, but I kept running into bugs in the NLTK NgramModel class (which has since been removed from NLTK).

The corpora directory has the infant-directed corpora that I used in my experiments. I provide copies here to aid future researchers who might want to replicate my results.
