Abstract:Unordered tree is widely used for semi-structured data modeling, coverage pattern mining on it has benefit for finding frequent subtrees without redundant information, so that improve the efficiency of subsequent knowledge discovering. A coverage pattern mining method MCRP is proposed. Firstly, all candidate subtrees are generated on the basis of maximum prefix coding and edge extension.Then coverage patterns are output by introducing δ ᇱ -coverage concept. Compared with traditional algorithms such as mining f… Show more
