These experimental corpora once again can be separated into "General-Purpose Corpora" that were collected for another purpose but have been analysed for referring expressions and "Dedicated Corpora" that focus specifically on referring expressions. Examples of General-Purpose Corpora are the Pear Stories, the Map Task corpus or
