Question: how ranking (clusters) and Ranking ( Cosine ) list have been computed here? According to my computation for Ranking(cluster) i am getting L2 as most similar cluster leader that contains 1,4,5 docs but the ranking listed over here shows Doc 3 as a 3rd most similar document to query which is not the member of the most similar leader L2. thank you
The 5 most relevant docs are asked. Cluster L2 just includes 3 documents. Thats why you have to look at the second most similar (L1 and L3 are equally - here L3 is chosen).
