Abstract :

Abstract— Mining frequent trees is very useful in domains like bioinformatics, web mining, mining semi-structured data, etc. The proposed frequent restrictedly embedded sub tree miner (FRESTM), is an efficient algorithm for mining frequent, unordered, embedded sub-trees in a database of labeled trees. The key contributions of our work are as follows: The algorithm enumerates all embedded, unordered trees. A new equivalence class extension scheme generates all candidate trees. The notion of scope-list joins is extended to compute the frequency of unordered trees. The performance evaluation on several synthetic and real world data shows that FRESTM is an efficient algorithm, which has performance comparable to TreeMiner, that mines only ordered trees. Keywords— Tree Mining, Embedded Trees, Unordered Trees, Pattern Mining.
