Class TestPOS

java.lang.Object

edu.illinois.cs.cogcomp.pos.TestPOS

public class TestPOS
extends Object

This program tests POSTagger on labeled data and reports its performance. All output is sent to STDOUT.

Usage

java edu.illinois.cs.cogcomp.lbj.pos.TestPOS <text file>

Input

The lone command line parameter is the name of a text file containing annotated natural language text. This file is expected to have one sentence per line, and the format of each line is as follows:

(pos1 spelling1) (pos2 spelling2) ... (posN spellingN)

It is also expected that there will be exactly one space between a part of speech and the corresponding spelling and between a closing parenthesis and an opening parenthesis.

Output

An ASCII table is written to STDOUT reporting precision, recall, and F₁ scores itemized by the POS tags discovered either in the labeled data or in the predictions. The two rightmost columns are named "LCount" and "PCount" (standing for "labeled count" and "predicted count" respectively), and they report the number of times the data contained each label and the number of times the classifier predicted each label respectively. In the last row, overall accuracy is reported in the precision column. In the count column, the total number of predictions (or labels, equivalently) is reported.
