Abstract
A method () for condition monitoring is disclosed, comprising registering () values (v) of movement characteristics measured for cycles of motion of a cyclically moving machine, associating () the occurrence of values in a frequency distribution (F) of the values with respective defined indexes (a, b, c, . . . ) based on intervals, generating () a word string (S) of the defined indexes corresponding to the occurrence of the values, segmenting () said word string (S) into a sub-set of words (s, s, . . . , s), determining () a frequency of the occurrence of the segmented words in said word string as a first reference term frequency (TF), associated with a first machine status (M), for subsequently registered set of values of movement characteristics, determining () a subsequent term frequency (TF), comparing () the subsequent term frequency (TF) with the first reference term frequency to determine a correlation with the first machine status.
