ANCOMP
NAME
ancomp -- compare two sets of annotations
SYNOPSIS
ancomp
(-a|-f|-l) (-r anitem) (-t anitem) (-m matchfile) (-h histfile) (-s samprate) file
DESCRIPTION
ancomp
is a program to compare two sets of annotations. It has three modes of operation
controlled by command-line switches. In
alignment accuracy
mode (-a) the program measure the alignment accuracy of a set of
automatically aligned annotations against a reference set.
Statistics of mean alignment error and a breakdown of
accuracy per annotation label is provided. It is assumed
that the labels themselves are correct.
In
frame labelling
mode (-f) the program samples the two annotation sets at a given frame
rate and counts how many times each possible pair of labels occurs.
A confusion matrix showing the mappings is produced.
In
labelling accuracy
mode (-l) the program only analyses the sequence of labels and not their
position. The program perfoms a dynamic programming assignment of test labels
to reference labels to collect statistics on substitutions, insertions and
deletions. A confusion matrix and labelling accuracy statistics are
produced.
OPTIONS
-I
Identify program name and version number.
-i item
Select input item number.
-r anitem
Select reference annotation item. Default first.
-t anitem
Select test annotation item. Default last.
-a
Select alignment accuracy mode (default).
-f
Select frame labelling mode.
-l
Select labelling accuracy mode.
-m matchfile
Store raw information about matches into the given file rather than
producing a summary. For frame labelling and
labelling accuracy mode this is a list of input-output label pairs suitable
for processing by the conmat(SFS1) confusion matrix printing program. If
matchfile is "-" then the information is sent to the standard output.
-h histfile
Store histogram of distances into given file.
-s samprate
Specify sampling rate for frame labelling measurement. Default:100.
