SimpleNLG for German

In 2010/2011, I worked on an adaption of the SimpleNLG library for German as part of my studies for my master’s degree. Since then, I have no longer been working in the field of natural language generation. Unfortunately, this means that my adaption has never quite been finished and “polished up” for release; I still decided to provide what I have for other people who might potentially be interested in it.

If you use SimpleNLG for German in your own work, please cite the following publication:

Features

SimpleNLG is a Java library for generation of grammatically correct sentences. Originally developed for English, I adapted it for German. For more information, please refer to the SimpleNLG tutorial.

Grammatical features covered by this adaption include, among others:

  • free ordering of sentence constituents, to account for the more flexible word order of German;
  • clusters of modal verbs; and
  • support for relative clauses and relative clause extraposition.

Limitations

As I’m not able to devote much time to the development of SimpleNLG for German anymore, this release still has some considerable limitations. The most important ones are:

  • it is based on the older version 3 architecture of SimpleNLG, which is now obsolete and also has a more restrictive license;
  • there is no proper lexicon – only a “toy lexicon” of around 100 entries is available – and lexicon lookup is quite slow and inefficient; and
  • it hasn’t been thoroughly tested for bugs.

If you have any questions specific to my adaption of SimpleNLG for German, please feel free to contact me. For questions about the original SimpleNLG, please refer to the SimpleNLG discussion list instead.

Finally, do not hesitate to get in touch with me if you would like to continue or contribute to the development of this software package (e.g., porting it to the newer version 4 architecture). I will do my best to assist you as much as time allows.
