PatMinr at Mac App Store analyse

PatMinr features four different state-of-the-art algorithms to extract all substring repetitions in a given sequence of characters. The four methods are the following: - BiDESt is an adaptation of the BIDE method (Wang et al., 2003) for substring pattern mining. - BiDEStOn is a new online version of BiDESt, specifically developed for PatMinr. - UkkoClos constructs a suffix tree (Ukkonen, 1995) and selects the closed patterns from the tree. - ClosUkko is a brand new approach that is faster than the three other methods in some cases. (Scientific paper currently under review) Simply enter a sequence, select one of the four methods, and press "Analyze". The results is shown in the form of a "Closed pattern tree". For instance, for "abracadabra", we obtain "a ∟bra" which means that "a" is a closed pattern, and "abra" is another closed pattern. "bra", for instance, is not a closed pattern, because it is simply a suffix of "abra" repeated the same number of times. For the text "abracadabra, banana", we obtain "a ∟bra ∟na b" which means that the closed patterns are "a", "abra", "ana" and "b". Scientific papers: J. Wang, J. Han, and C.
