Morphological disambiguation

The project uses vislcg, an implementation of constraint grammar, as developed by a.o. Fred Karlsson and Pasi Tapanainen at the University of Helsinki.

Other versions of constraint grammar

The philosophy behind constraint grammar is relatively simple, and the programming algorithms are found in several different version.
  1. The original CG formalism was developed by Fred Karlsson, at Dept. of Linguistics in Helsinki
  2. Bart Jongejan's C++ version of the original CG
  3. A new version of CG, called CG-2, was developed by Pasi Tapanainen, cf. Tapanainen 1996. It is maintained by Connexor
  4. vislcg, an open source implementation of CG-2, at http://visl.hum.sdu.dk/visl/.

Other disambiguation tools

Grammar-based disambiguation tools

For various reasons, do not use these tools, but have chosen constraint grammar instead. These alternative approaches should still be avaluated on aregular basis.

Statistically-based disambiguation tools

This is the dominating approach to disambiguation. Here, we think the grammar-based approach is on the right track, and we thus do not use statistically-based tools. In the future it still may be relevant to have a look at what statixtically-based tools may achieve when applied on the top of grammar-based disambiguation tools, in order to resolve on statistical grounds such open cases that cannot be dealt with by grammatical tools alone.

Thus, we should at some point start orientating ourself in the world of statistically-based disambiguation tools.
