We would like to describe the relationship between word sense disambiguation (WSD) and language resources (LR) working with word senses. We discuss the problem of sense division and tagging. Exploiting specific features of the inflectional languages for WSD is encouraged. We present WSD methods for Czech ambiguous nouns. The advantage of these methods consists in reducing the manual work by using a synonym training set. They could be utilized for building a semantically annotated corpus or gaining glosses for Czech WordNet.
