See below for a quick guide on how to use them. All scripts written for Python 2.7. Visualisation requires the free matplotlib toolbox (http://matplotlib.org), numpy and scipy. -By default, the scripts can be run from the ‘scripts’ folder, with the result files in the ‘saves’ folder (the default location where result XMLs are stored).

Each script takes the XML file folder as an argument, along with other arguments in some cases. +Note: to avoid all kinds of problems, please avoid using spaces in file and folder names (this may work on some systems, but others don’t like it). comment_parser.py Extracts comments from the output XML files corresponding with the different subjects found in ‘saves/’. It creates a folder per ‘audioholder’/page it finds, and stores a CSV file with comments for every ‘audioelement’/fragment within these respective ‘audioholders’/pages. In this CSV file, every line corresponds with a subject/output XML file. Depending on the settings, the first column containing the name of the corresponding XML file can be omitted (for anonymisation). @@ -100,6 +101,9 @@ evaluation_stats.py Shows a few statistics of tests in the ‘saves/‘ folder so far, mainly for checking for errors.

Creates the folder ‘saves/ratings/‘ if not yet created, to which it writes a separate file for every ‘audioholder’/page in any of the output XMLs it finds in ‘saves/‘. Within each file, rows represent different subjects (output XML file names) and columns represent different ‘audioelements’/fragments.
