<｜begin▁of▁sentence｜>### Instruction:
I understand that you have a dataset of political blogs in a gml file format named "polblogs.gml." You want to apply the significance community detection algorithm from the cdlib library to identify the communities within the graph. Once the communities are detected, you would like to have the results in JSON format.
### Response:
import networkx as nx
from cdlib import algorithms

# Read the graph from the gml file
G = nx.read_gml('polblogs.gml')

# Apply the significance community detection algorithm
communities = algorithms.significance_communities(G)

# Convert the communities to a JSON object
communities_json = communities.to_json()

print(communities_json)
