Having chosen cosine similarity as the context similarity measure, we compute the similarity between ctx(bank 2 ∪ {bank}) and the context of every sense of building in Table 3: cos(ctx(bank 2 ) ∪ {bank}, ctx(building 1 )) = 2 3 and cos(ctx(bank 2 ) ∪ {bank}, ctx(building 2 )) = 0.
for the word building in the Matching the meaning of the ambiguous node "building" in the context of the sense bank 2 .
