About the corpus

The TUNA Reference Corpus is a semantically and pragmatically transparent corpus of identifying references to objects in visual domains. It was constructed via an online experiment, and has since been used in a number of evaluation studies on Referring Expressions Generation, as well as in two Shared Tasks: the Attribute Selection for Referring Expressions Generation task (2007), and the Referring Expression Generation task (2008).


Obtaining the TUNA Corpus

A version of the corpus was released for public distribution in October 2009. It forms part of the ELRA Language Resources Catalogue, and can be obtained by contacting ELRA directly. Alternatively, you can download the latest distribution from here.
