These instructions describe how to inspect the coreference
annoted corpus with MMAX2, the tool that has also been used
to conduct the annotation. Once a file has been opened in 
MMAX2, corefernce information can be inspected by clicking on 
the beginning of a word marked with brackets.


Download MMAX2

Download MMAX2 from http://sourceforge.net/projects/mmax2/
(tested with MMAX2_1.13.003b.zip, 4.7 MB, as of 2010-07-24)

Unpack annotated corpus files from the ACL submission, 
attached resources (If you read this, you probably
have already done this).

Installation

To install MMAX2 just extract the distribution archive into a folder
of your choice. MMAX2 is written in Java and requires a Java 5 Runtime
Environment (JRE). MMAX2 is then started by executing the script
mmax2

./mmax2.sh P08-1045/P08-1045.mmax

Opening MMAX2 Projects

For each paper to annotate, there is a corresponding MMAX2 project
consisting of several files and subfolders. The main project file to
load from the MMAX2 annotation tool via the File → Load menu is the
one with the .mmax suffix. After loading, MMAX2 prompts the user if he
wants to validate the annotation. This is only necessary if the
annotation has been manipulated outside of MMAX2, so you can usually
choose Do not validate. 

MMAX2 Windows

MMAX2 consists of three windows: the markable level control panel, the
attribute window and the main window, all of which are described in
the following sections. 

The Markable Level Control Panel

The markable level control panel which is usually opened on the upper
right lists all annotation levels. In our annotation task, we have two
annotation levels: coref for your coreference annotations and
sentence; the latter is created automatically and is only used for
formatting the document (inserting line breaks after each
sentence). It is therefore recommended to change the status of the
sentence level from active to visible by selecting the corresponding
entry in the drop-down menu. This has also the effect that you don’t
have to explicitly choose the annotation level when working with
markables in the main window since only the coref level is active
now. After this modification, the markable level control panel is not
needed anymore and can be removed by minimizing it or by unchecking
the Show ML Panel checkbox in the tool bar of the main window.

Further information on how to use MMAX is also in 
file:AnnotationGuidelines.html#HowtoAnnotatewithMMAX2
that is part of this distribution.
