Bratify

Bratify is a program that produces Brat-formatted class hierarchy and labels from an OWL file.

Running the program

Edit the following information in the run_bratify.py file (see example below).

Specify the paths to:

• the input OWL file
• the output file formatted for brat visual.conf
• the output file formatted for brat annotation.conf

Specify the output format (1 or 2) of the labels for Brat's system and for visualization.conf.

1 = brat_syst_format | normal term format | ID

For example:

Matthew-Wood_syndrome | Matthew-Wood syndrome | DOID_0050819

2 = ID | normal term format

For example:

DOID_0050819 | Matthew-Wood syndrome

Specify the SPARQL query to get the labels and the PURLs for each class in the OWL file.

Run bratify.py for the specified ontology by adding a call to the function.

    # 1 = brat_syst_format | normal term format | ID 
    # 2 = ID | normal term format
