SimpleNLG is a simple Java API designed to facilitate the generation of Natural Language. It was originally developed by Ehud Reiter, Professor at the University of Aberdeen's Department of Computing Science and co-founder of Arria NLG. The discussion list for SimpleNLG is on Google Groups.
SimpleNLG is intended to function as a "realisation engine" for Natural Language Generation architectures, and has been used successfully in a number of projects, both academic and commercial. It handles the following:
- Lexicon/morphology system: The default lexicon computes inflected forms (morphological realisation). We believe this has fair coverage. Better coverage can be obtained by using the NIH Specialist Lexicon (which is supported by SimpleNLG).
- Realiser: Generates texts from a syntactic form. Grammatical coverage is limited compared to tools such as KPML and FUF/SURGE, but we believe it is adequate for many NLG tasks.
- Microplanning: Currently just simple aggregation, hopefully will grow over time.
Current release (English)
The current release of SimpleNLG is V4.5.0 (API). The "official" version of SimpleNLG only produces texts in English. However, versions for other languages are under development, see the Papers and Publications page and SimpleNLG discussion list for details.
Please note that earlier versions of SimpleNLG have different licensing, in particular versions before V4.0 cannot be used commercially.
The quickest way to use SimpleNLG is to add it as a dependency to your maven
<dependency> <groupId>uk.ac.abdn</groupId> <artifactId>SimpleNLG</artifactId> <version>4.5.0</version> </dependency>
