UD for Danish
Tokenization and Word Segmentation
- Words are generally delimited by whitespace or punctuation. Exceptions:
- Numerical expressions (including dates) are treated as single words and may contain punctuation or whitespace: 1.1.1970, 11:00, 2 000.
- Multiword tokens are not used in Danish.
Morphology
Tags
- Danish uses all 17 universal tags.
- The only words tagged PART are the infinitive marker at and the negation particle ikke.
- Auxiliaries (AUX) are all verbal in Danish and can be grouped into four types:
- The copula være (be).
- The temporal auxiliary have (have), which combines with the participle of the main verb to form perfect tenses.
- The passive auxiliary blive (get/become), which combines with the past participle of the main verb to form passives.
- Modal and aspectual verbs that combine with the bare infinitive of the main verb, such as måtte (must) and kunne (could).
- The tag DET is used for articles and pronominal words used with a determiner function, including possessives. The tag PRON is reserved for pronouns occurring as the head of a noun phrase.
- Participles (both present and past) are mainly used adjectivally in Danish and are generally tagged ADJ. The only exception is that past participles used to form periphrastic passives are tagged VERB.
For more information, see the list of Danish POS tags.
Features
- Nouns have inherent Gender and inflect for Number (singular or plural), Definite (indefinite or definite) and Case (nominative or genitive).
- Verbs inflect for Voice (active or passive). Finite forms in indicative mood in addition inflect for Tense (present or paste). There are two types of nonfinite forms: infinitives and participles (present and past).
- Adjectives agree with nouns (in both attributive and predicate position) with respect to the features Gender, Number and Definite. In addition, many adjectives inflect for Degree (positive, comparative, superlative) and for Case when used to head noun phrases.
- Adverbs inflect only for Degree.
- Personal pronouns inflect for Case with three values (nominative, accusative, genitive).
- Determiners agree with nouns in the same way as adjectives.
Syntax
- Subjects have the following characteristics:
- Word order: Subjects immediately follow the finite verb and precede negation in verb-initial main clauses.
- Case marking: Subjects occur in nominative case without adpositions.
- Passivization: Subjects are suppressed when verbs (both intransitive and transitive) are passivized.
- Control: Subjects control the subjects of absolute adverbials.
- Relativization: Relative pronouns with subject function cannot be omitted.
- Objects have the following characteristics:
- Word order: Objects immediately follow the main verb unless topicalized.
- Case marking: Objects occur in nominative case (if nouns) or accusative case (if pronouns) without adpositions.
- Passivization: Objects become (non-expletive) subjects when verbs are passivized.
- The copula verb være (be) is used in equational, attributional, locative, possessive and benefactory nonverbal clauses. Existential clauses use the same verb but with different syntax, with the expletive der (there).
- The following subtypes are used in Danish:
- acl:relcl for relative clauses
- advmod:lmod for adverbial modifiers expressing location
- aux:pass for passive auxiliaries
- compound:prt for verb particles
- csubj:pass for clausal subjects of passive verbs
- nmod:poss for possessive/genitive modifiers
- nsubj:pass for nominal subjects of passive verbs
- obl:agent for agents of passive verbs
- obl:lmod for oblique modifiers expressing location
- obl:tmod for oblique modifiers expressing time
