The starting point for curation is results from reading (e.g., from REACH), in the form of a pickled dictionary with lists of INDRA statements keyed by paper.
The first step is generate a list of agent texts with grounding (abbreviated "twg" in filenames), that shows the entity texts in order of their frequency of occurrence along with all of the different identifiers they are grounded to across the corpus (often the same string is grounded to different IDs depending on the context of the paper). You'll also want the comparable list after filtering out agent texts that are already in the default grounding map.
To dump both of these files as CSV, run the grounding_mapper top-level script on pickled reading output. For example, for the REACH output from the batch 4 evaluation:
python -m indra.preassembler.grounding_mapper <filename>
