Ace2txt: from Multilevel Annotation to raw Text

This paper presents a software, called ace2txt2004, which converts the annotation format used in the ACE program into text, and places it in context. The software, written in python and released as an open source program, was tested on ACE 2004. This program is very useful for the extraction of the annotation from ACE corpora and the conversion in the .ar format used for running machine learning experiments under several environments.
