Koreference a typy reference v češtině
Coreference and types of reference in Czech
Languages of publication
The article deals with coreference relations in Czech and their classification based on the classification of reference types. First, we define the notion of coreference, putting stress on the distinction between coreference and endophora. Then the scheme of reference and coreference used in the annotation of the coreferential relations in the Prague Dependency Treebank (PDT) is presented, where two types of coreferential relations are applied: the type SPEC and the type GEN. Analyzing several examples, we argue that this scheme is not capable of describing more complicated reference relations, which results especially from the too broad definition of the type GEN. Hence we suggest an alternative classification of the types of reference, employing two independent criteria: the criterion of genericity and the criterion of specificity, so that four types of reference are established: specific individual, non-specific individual, specific generic and non-specific generic. We deal with each of these four types in detail, and finally, we show how this classification can be used when capturing coreference relations in text.
