The Unberable Lightness of Tagging* A Case Study in Morphosyntactic Tagging of Polish

The article takes a step back and examines the notion of part of speech (POS), arguing that POS tagsets should be constructed more carefully and, in effect, should be light in at least three senses: 1) they should pay less heed to the traditionally ill-defined notion of POS, 2) they should adopt clear POS delimitation criteria based on solely formal (morphological and morphosyntactic) properties, and 3) tags should be assigned to light units, typically not longer than orthographic words. A tagset for Polish constructed on the basis of such criteria is presented.
