The HCRC Map Task Corpus is a set of 128 dialogues that has been recorded, transcribed, and annotated for a wide range of behaviours, and has been released for research purposes. It was originally designed to elicit behaviours that answer specific research questions in linguistics. You can read more about the design here. Since the original material was released in 1992, the corpus design has been used not just for linguistics research, but also in teaching and by computational linguists for training machine classifiers.

Since HCRC continues to use the Corpus in our own research, we welcome contact with colleagues engaged in similar projects. For this reason we ask users to notify us at as a matter of courtesy of the topic of their intended work with these materials.

Because the Map Task is available in a number of forms, we provide a brief history explaining what these are what they contain. The simplest way to acquire the corpus is by download; see "NXT-format XML Annotations (v2.0) and Accompanying Audio" near the bottom of this page.
