Abstract
The issue of incompatible morphosyntactic tagsets in multilingual corpora could be solved by an abstract hierarchy of concepts, mapped to language-specific tagsets. The hierarchy supports the user and tools by resolving categories that do not match the relevant tagset in queries, by providing links between language-specific tagsets, and by displaying responses using a preferred tagset.
The hierarchy, built using the methods of Formal Concept Analysis, can also help to refine morphosyntactic annotation in one language by using word-to-word alignments to parallel texts tagged by a different tagset.
