Phylogenetic tree construction method based on sequence pattern mining algorithm

The invention relates to a phylogenetic tree construction method based on a sequence pattern mining algorithm. The phylogenetic tree construction method based on the sequence pattern mining algorithmcomprises the following steps: mining a specific pattern which is hidden in a sequence set and can be used for measuring sequence similarity to obtain an initial pattern set; filtering an unclosed frequent pattern in the initial patter set to acquire an optimized pattern set capable of representing the sequence set; and constructing a patter vector set and calculating the distance between numericvectors so as to construct a distance matrix for producing a phylogenetic tree. The sequence pattern which frequently appears in the sequence set is extracted by a sequence patter mining algorithm, the sequence set is converted into binary system by the filtered pattern set or the distance matrix is calculated in the form of giving weight information to the pattern vector set, and then the phylogenetic tree is constructed. For the large-scale and low-similarity sequence set, the more representative pattern in the sequence set can be mined by utilizing a pattern growth strategy, so that the extraction of a redundancy pattern which is useless for measuring sequence similarity is voided and measurement on the similarity among the sequences within the global range is optimized.
