Version 1 (Prokopis Prokopidis, 2016-02-16 12:29 PM) → Version 2/6 (Vassilis Papavassiliou, 2016-05-31 04:51 PM)
# Near Deduplication
Examines the cesDoc files in a directory and removes (near)duplicates.
It processes the exported cesDoc files (so the argument of option -i should be the crawlpath up to the "xml" directory) and detects near duplicates.
It also creates a text file (based on the argument of option -bs) with a list of the fullpaths of the remaining cesDoc files.
If asked (-oxslt option is used) an HTML file with links pointing to the xls transformations is generated too.

-dedup : for (near) deduplication.
Some more supported parameters are explained in gr.ilsp.fc.dedup.DeduplicatorOptions
-m : Method type for deduplication: 1 for deduplication based on lists of words and quantized frequencies, 2 for deduplication based on common paragraphs, and 0 for applying both methods (default).
-mtl : minimum length of a token. Tokens with less than MIN_TOK_LEN (default is 3) are excluded from content and are not included into list of words.
-mpl : minimum length of a paragraph in tokens. Paragraphs with less than MIN_PAR_LEN (default is 3) tokens are excluded from content.
-ithr : intersection of paragraphs. Documents for which the ratio the common paragraphs
with the shortest of them is more than this threshold are considered duplicates
-int : inputType. Type of input files, default is xml, also supports txt.
-ex : exclude files. List of CesDocFiles (separated by ;) to be excluded from deduplication.
