cssdiff

cssdiff(1)							      CRM114								cssdiff(1)

  NAME
      cssdiff - generate a difference summary of two .css files

  SYNOPSIS
      cssdiff [cssfile 1] [cssfile 2]

  WARNING
      This  man  page  is  taken from an older CRM114 version.	It is provided as a convenience to Debian users and may not be up-to-date.  If you
      would like to update it, please send appropriate patches to the Debian bug tracking system.

  DESCRIPTION
      cssdiff is a special-purpose utility to measure the distance between the classes represented by cssfile1 and cssfile2.  The  summary  result
      output  tells  how  many	features  were in each of the .css files, how many features appeared in both (balanced overlap), how many features
      appeared only in one (or unbalanced overlaps), and how often the feature set of one .css file strictly dominated the feature set of  another
      .css  file.  This set of metrics provides an intuitive way to determine the similarity (or dissimilarity) of two classes represented as .css
      files.  When using the CRM114 spamfilter, it can be used to find out how easy it will be for CRM114 to differentiate spam from nonspam  with
      your .css files.	cssdiff prints a report like e.g.

	 Sparse spectra file spam.css has 1048577 bins total
	 Sparse spectra file nonspam.css has 1048577 bins total

	 File 1 total features		  :	 1605968
	 File 2 total features		  :	 1045152

	 Similarities between files	  :	  142039
	 Differences between files	  :	 1279964

	 File 1 dominates file 2	  :	 1463929
	 File 2 dominates file 1	  :	  903113

      Note that in this case there's a big difference between the two files; in this case there are about 10 times as many differences between the
      two files as there are similarities.

  OPTIONS
      There are no options to cssdiff.

  SHORTCOMINGS
      Note that cssdiff as of version 20040816 is NOT capable of dealing with the CRM114 Winnow classifier's  floating-point  .cow  files.  Worse,
      cssdiff  is  unaware of it's shortcomings, and will try anyway. The only recourse is to be aware of this issue and not use cssdiff on Winnow
      classifier floating point .cow format files.
