An Extensible Toolkit for Computational Semantics

In this paper we focus on the software for computational semantics provided by the Python-based Natural Language Toolkit (nltk). The semantics modules in nltk are inspired in large part by the approach developed in Blackburn and Bos (2005) (henceforth referred to as B&B). Since Blackburn and Bos have also provided a software suite to accompany their excellent textbook, one might ask what the justification is for the nltk offering, which is similarly slanted towards teaching computational semantics.
