public class Benchmark

extends java.lang.Object

This class is a simple benchmark for the stemmer. You need to provide it with a test file, containing words to stem. The file will be processed three times, and at the end the application will print a short report. NOTE: the file encoding is assumed to be UTF-8.

Method Detail

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

Provide the name of the test file as the first argument. The test file should contain just the words to stem, any other tokens will skew the results. Words must be separated by space(s) and/or newlines.

The second, optional argument is a resource path to the stemmer table to be used instead of the default one.

Timing includes only the time it takes for the Stemmer.stem(String, boolean) method to return a value. Stemmer.MIN_LENGTH is set to 0 in order to process all input tokens.

Throws:

java.lang.Exception

                                  long[] res)
