The EAGLES 'Recommendations for the Morphosyntactic Annotation of
Corpora' (available at
http://www.ilc.pi.cnr.it/EAGLES/annotate/annotate.html) provide a
formalism which can deal with values for multiple morphosyntactic
categories in a single tag, and also has facilities for dealing with
underspecification and ambiguity. The tag is a linear string of
characters, where each character represents a value for a particular
morphosyntactic feature. For example (from the document cited above):
- A common noun, feminine, plural, countable, is represented: N122010
- A 3rd person, singular, finite, indicative, past tense, active, main verb,
+non-phrasal, non-reflexive, verb is
represented: V3011141101200
As far as I know, these recommendations were drawn up for and have been
used with mainly West European languages such as English, French and
Italian, but it seems to me that they could be usefully applied to more
morphologically rich inflectional languages,
