Abstract: A dynamic clustering algorithm is used to process log data to generate pattern information. A word frequency map may be generated and/or updated based at least in part on entries of the log data. The word frequency map may indicate occurrences of words in the log data. In addition a modified word frequency map may be determined based at least in part on the frequency of adjacent words as indicated in the word frequency map. Based at least in part on the modified word frequency map a line threshold is determined. The line threshold indicating a common frequency indicated in the modified word frequency map. The line threshold may then be used to generate a pattern for an entry of the log data.
