A document examiner examines handwriting mainly by a qualitative method based on his/her knowledge and experiences. The qualitative examination, compared with the quantitative examination, possesses less objectivity and is believed to be less reliable. However, an examiner’s opinion is, in fact, highly reliable. The knowledge and strategies that a document examiner uses is discussed in this paper. Four kinds of classification experiments where diagram-like 36 handwriting samples written by 6 writers were used as stimuli were done by visual inspection and cluster analysis. Results of the experiments suggested that the examiner utilized his knowledge on writing motion even when the classification target was a diagram drawn by the reconstruction of a handwriting sample.
