<｜begin▁of▁sentence｜>### Instruction:
As a Quality Assurance Analyst, your task is to assess and test a network analysis software tool called LPANNI for community detection using the cdlib library. You are required to detect overlapping community structures within a word adjacencies graph loaded from a gml file named adjnoun.gml. Your goal is to provide the results of the community detection process in JSON format for further analysis and evaluation.
### Response:
import networkx as nx
from cdlib import algorithms

# Read the graph structure from a GML file
G = nx.read_gml('adjnoun.gml')

# Apply LPANNI community detection algorithm
communities = algorithms.lpanni(G)

# Output communities as JSON
communities_json = communities.to_json()
print(communities_json)
