Usage

Format

A data frame with 700 observations on the following 13 variables.

Verb

a factor with the verbs as levels.

WrittenFrequency

a numeric vector of logarithmically transformed frequencies in written Dutch (as available in the CELEX lexical database).

NcountStem

a numeric vector for the number of orthographic neighbors.

VerbalSynsets

a numeric vector for the number of verbal synsets in WordNet.

MeanBigramFrequency

a numeric vector for mean log bigram frequency.

InflectionalEntropy

a numeric vector for Shannon's entropy calculated for the word's inflectional variants.

Auxiliary

a factor with levels hebben, zijn and zijnheb for the verb's auxiliary in the perfect tenses.

Regularity

a factor with levels irregular and regular.

LengthInLetters

a numeric vector of the word's orthographic length.

FamilySize

a numeric vector for the number of types in the word's morphological family.

Valency

a numeric vector for the verb's valency, estimated by its number of argument structures.

NVratio

a numeric vector for the log-transformed ratio of the nominal and verbal frequencies of use.

WrittenSpokenRatio

a numeric vector for the log-transformed ratio of the frequencies in written and spoken Dutch.
