Estonian Particle Verbs And Their Syntactic Analysis

This article investigates the role of particle verbs in the Estonian computational syntax in the framework of Constraint Grammar, a rule-based system that performs morphological disambiguation, determines grammatical relations and analyses dependency structure of a sentence. For recognizing the particle verbs, two-fold approach is used: non-compositional particle verbs are listed in a lexicon and compositional ones are composed by the rules. The system achieves both 97.4 % precision and 97.4 % recall for particle verb recognition. The plans for future include building a valency lexicon of particle verbs and utilizing that in syntactic analysis
