7.2. The ePOS tag set for Danish 147
7.2.2.1 Nouns
Nouns are sub-classified into common nouns (C) and proper nouns (P).
Like in PAROLE, gender is considered an inflectional category, in ONC it is
considered an inherent information. The ePOS marker pattern for common
nouns is
CAT NUM DEF CAS GEN TMP VOC DEG PER RFL POS
NC + + + + − − − − − −
Number [NUM]: singular, plural.
Definiteness [DEF]: indefinite, definite.
Case [CAS]: unmarked, genitive, fossilized. Fossilized case is found in examples
like til huse, i aftes.
Gender [GEN]: common, neuter.
The ePOS marker pattern for proper nouns is
CAT NUM DEF CAS GEN TMP VOC DEG PER RFL POS
NP + + + + - - - - - -
Proper nouns 6 only have marker alternation for case (genitive/unmarked).
However, they are implicitly also marked for number (always singular), definiteness
(always indefinite, and gender (either common or neuter).
As the applied token concept underlying ePOS in its initial form is that
one described in Chapter 4, multiword proper nouns cannot be identified
as one entity but will be tagged token by token, e.g. Det [PD:nsu-/----/----]
Kongelige [AC:xsud/----/p---] Bibliotek [NC:nsui/----/----].
In the converted version of the corpus, where multiword tokens have
been split up into individual tokens, case may be dative if the noun is governed
by certain prepositions. This is indicated by an F (≈ ‘fossilized’) as
case marker that has been added to the PAROLE inventory. The same applies
to adjectives, cf. til fulde, with the extra PAROLE tag ANPCSF=IU.
