a search engine, using paper title as query
•Our
method tries to approximate this
•For
each citation c in C
–Query search engine with title
of c as phrase search to obtain a set
of relevant URLs
–Represent c by a feature
vector of relevant URLs and weighting scheme
•Apply
hierarchical agglomerative clustering (HAC) on C to
derive k clusters
–Cosine similarity
–Tested with single link, complete
link and group average
