From Dependencies to Constituents in the Reference Corpus for the Processing of Basque (EPEC)

In this paper the process for turning a dependency-based corpus to a constituentbased one is explained. For this purpose, first both the Dependency and the Constituent formalism are analized and then the corresponding equivalences of linguistic phenomena are treated. This process has had different phases in which the linguistic equivalences have been improved. Finally, the evaluation process is briefly explained and, as a result, we get corpora annotated in the two different formalisms usually proposed for syntactic tagging. If the linguistic equivalences are the same, the conversion process could be expanded to other corpus; otherwise, new equivalences should be defined.
