    Efficient mining of frequent rooted continuous directed subgraphs
    (2006) Sreenivasa, G.J.; Ananthanarayana, V.S.
    Mining frequent rooted continuous directed (RCD) subgraphs is very useful in Web usage mining domain. We formulate the problem of mining RCD subgraphs in a database of rooted labeled continuous directed graphs. We propose a novel approach of merging like RCD subgraphs. This approach builds a Pattern Super Graph (PSG) structure. This PSG is a compact structure and ideal for extracting frequent patterns in the form of RCD subgraphs. The PSG based mine avoids costly, repeated database scans and there is no generation of candidates. Results obtained are appreciating the approach proposed. � 2006 IEEE.
