| Abstract(in English) | Data-Mining or Text-Mining, that is technique to extract non-obvious information from semi-structured texts, has been very important technologies when we handle expanding information in WWW. One of them is to discover patterns that appear in the data repetitively. Using the patterns, we can process the data and can extract from the data. To discover them, we can think about the naive method, i.e. the method of aligning data with that own shifted copy data, and compare them. However, when the size of the text is n, time complexity of this method becomes O(n^2), and it isn't efficient for big data. In this paper, we propose the technique to reduce time complexity of the method to O(n log n) using our string matching algorithm with mismatches. |
