-Using this method we can compute average word frequency class values (AWFC) for arbitrary parts of the text. The change
-of this value between two adjacent text windows indicates change of writing style, which can be caused by a plagiarism.
-We computed AWFC value for every text window of size 45 words, which was shifted through the text by 40 words span.
-The values of window size and span of shifting was set empirically during training. Windows with
-largest change of AWFC compared to AWFC of their neighbouring previous window were selected as candidate for query extraction.
