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.
- The original CG formalism was developed by Fred Karlsson, at Dept. of Linguistics in Helsinki
- Bart Jongejan's C++ version of the original CG
- A new version of CG, called CG-2, was developed by Pasi Tapanainen, cf. Tapanainen 1996. It is maintained by Connexor
- 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.
