<｜begin▁of▁sentence｜>### Instruction:
As a network analyst working in a scientific research lab, you have been tasked with analyzing collaboration patterns in the field of condensed matter physics. You have access to a dataset in a gml file named cond-mat-2005.gml, which contains the collaboration network of researchers in 2005. Your task is to use the Louvain method in the cdlib library to perform community detection on this network, and then compute the link modularity to assess the quality of the identified communities.
### Response:
import networkx as nx
from cdlib import algorithms, evaluation

# Read the condensed matter collaborations 2005 graph
G = nx.read_gml('cond-mat-2005.gml')

# Perform community detection using the Louvain method
communities = algorithms.louvain(G)

# Compute the link modularity
link_modularity = evaluation.link_modularity(G, communities)

# Print the result
print(link_modularity.score)
