RFTagger Java Interface

Introduction

RFTagger Java Interface is a flavour of Helmut Schmid's and Florian Laws' RFTagger that runs as a library and application in Java. It uses their original code as a binary library which is loaded automagically. It features many small but nice improvements and works out of the box on all major three platforms.

RFTagger Java Interface is brought to you by Ramon Ziai and Niels Ott, funded by SFB 833, Project A4.

Features

RFTagger Java Interface can do everything that the original version can do. And it can do even more. Here's the list of improvements:

Refuses to load incompatible parameter files files.
Auto-select of 32bit vs 64bit parameter files (library only)
Handles the encoding of parameter files and therefore works flawlessly on UTF8-based systems
Can additionally output STTS tags (only German STTS, for other languages, we need further development)
Runs on Linux, OS X, and Windows, both 32bit and 64bit, out of the box.
Is available as an easy-to-use Java library as well as a standalone tool.

Using it on the Command Line

Type java -jar rft-java.jar and there you go. You'll need the parameter files that come with the original RFTagger

Using it as a Library

Basic usage:
// initializing parameter file (aka: auto-select the right model) Model model = new Model(new File("/home/rftj/german-pc-32bit.par"), new File("/home/rftj/german-pc-64bit.par")); // initialize the tagger with defaults RFTagger rft = new RFTagger(model); // do some tagging String[] words = new String[]{"Das", "ist", "ein", "Test", "."}; List<String> tags = rft.getTags(Arrays.asList(words));

Using the tagset converter:

 TagsetConverter conv = ConverterFactory.getConverter("stts");

                List<String> sttsTags = new LinkedList<String>();
 for ( String tag
                : tags ) {
 sttsTags.add(conv.rftag2tag(tag));
 }

TODO

Beta-testing
Test STTS mapping
Develop other tagset mappings or accept contributions
Once beta status has been overcome, release source code

Known Issues

Windows version works only in MinGW shell for now. We need to compile a static library but we are not Windows experts.

Requirements

Java 6 (comes with any reasonably OS anyways)
