Coping with Derivation in the Bulgarian Wordnet

The paper motivates a strategy for identification and annotation of derivational relations in the Bulgarian wordnet that aims at coping with the complex morphology of the language in an elegant way. Our method involves transfer of the Princeton WordNet (morpho)semantic relations into the Bulgarian wordnet, at the level of the synset, and further detection of derivational relations between literals in Bulgarian. Derivational relations have been annotated to reflect the complexity of Bulgarian morphology. Introduced literal relations improve the consistency and employability of the
