<｜begin▁of▁sentence｜>### Instruction:
Given a graph with edge set [(0, 1), (0, 2), (1, 2), (3, 2), (3, 4), (4, 2), (4, 5), (5, 3)], representing citations among articles (where an edge (a, b) means article a cites article b), can you use the cocitation function in igraph to calculate the cocitation score for a pair of articles?
### Response:
import igraph as ig

# Create a simple undirected graph with edges representing citations
edges = [(0, 1), (0, 2), (1, 2), (3, 2), (3, 4), (4, 2), (4, 5), (5, 3)]
g = ig.Graph(edges=edges)

# Calculate the cocitation for vertices 2 and 3, which are both cited by vertex 4
cocitation_score = g.cocitation([2, 3])

# Print the cocitation score
print(f'Cocitation score between vertices 2 and 3 is: {cocitation_score}')
