Abstract. Morphological case tagging is essential for the identification of the syntactic and semantic roles of sentence constituents in most inflectional languages. Although it is usually viewed as a side-task of general tagging applications, it is addressed in the present work as an individual, stand-alone application. Supervised learning is applied to Modern Greek textual data in order to case-tag declinable words using merely elementary lexical information and local context. Several experiments with various context window sizes, as well as base- and meta-learning schemata, were run with promising results.
