<｜begin▁of▁sentence｜>### Instruction:
Given the Word adjacencies graph from a GML file named adjnoun.gml, can you use the Louvain method from cdlib to perform community detection and then initialize a MatchingResult object with the resulting communities to compare them to themselves? Output the JSON representation of the MatchingResult.
### Response:
import networkx as nx
from cdlib import algorithms, evaluation

# Create a graph from the word adjacencies dataset
g = nx.read_gml('adjnoun.gml')

# Apply a community detection algorithm
c = algorithms.louvain(g)

# Initialize MatchingResult object
matching = evaluation.MatchingResult(c, c)

# Convert the MatchingResult to JSON format
json_result = matching.to_json()

print(json_result)
