[Query about a concept] What is "occurrence" in Community Schema?

[yagneshgooglegithub]

The code is too complex to make something out of. A quick simple description with a small example would be of a great help. The line is v["occurrence"] = len(v["chunk_ids"]) / max_num_ids in gdb_networx.py

Simple understanding is that, the community involves more chunks, its occurrence is higher.
