HeLI off-the-shelf language identifier with language models for 200 languages. The program will read the <infile> and classify the language of each line as one of the 200 languages it knows and writes the results, one ISO 639-3 code per line, into file <outfile>. It can identify c. 3000 sentences per second using one core on a 2021 laptop and around 3 gigabytes of memory.

Usage:
java -jar HeLI.jar -r <infile> -w <outfile>

The program will read the <infile> and classify the language of each line as one of the 200 languages it knows
and writes the results, one ISO 639-3 code per line, into file <outfile>.

You can use the -c option to make the program print a confidence score for the identification after each language code.

Usage:
java -jar HeLI.jar -c -r <infile> -w <outfile>

You can give the list of comma-separated ISO 639-3 identifiers for relevant languages after -l option.

Usage:
java -jar HeLI.jar -r <infile> -w <outfile> -l fin,swe,eng

You can give the number of top-scored languages to print after the -t option. (overrides confidence)

Usage:
java -jar HeLI.jar -r <infile> -w <outfile> -l fin,swe,eng -t 2

If you omit both of the filenames, the program will read the standard input one line at a time and write the result to standard output.
