adjusted_frequency.pl - computes the adjusted frequency of entries.
adjusted_frequency.pl [-h|--help --man -c|--columns] DATA
DATA is a tab-delimited file with any number of fields for the entry (e.g. lemma), one field (second last) for the class (e.g. genre), and one field (last) for the frequency of that class. Could be redirected from STDIN.
-h|--help--man-c|--columns
A tab-delimited file with adjusted frequency, and original entry fields.
This Perl script computes the Adjusted Frequency (AF), or Korrigierte Frequenz, for each entry. AF was introduced by Inger Rosengren: Ein Frekvenzwörterbuch der deutschen Zeitungssprache, 1972, Gleerup Lund. It is computed as follows:
AF = ( sum[i = 1 to n]( sqrt( d[i] * x[i] ) ) )^2
where
n = number of classes
d[i] = relative size of class i
x[i] = frequency in class i
Prints to STDOUT.
