A Treebank-based Investigation of IPP-triggering Verbs in Dutch

viant ending, the correct base form (lemma) is entered, and a shortcut brings up the
paradigm(s) associated with the base form (the field Is a variant of in figure 4). The
paradigm is then presented as a list of all existing word forms with their morphological
features, from which the annotator selects one or more paradigm rows with
the appropriate features. If there is no such set of features, as will be the case when
a word is used with deviating gender, the features must be typed in manually in the
Features field. In the example in figure 4, the word kjelleren ‘the basement’ has
been spelled with an apostrophe rather than the vowel e, representing a common
pronunciation where the schwa in the final syllable has been dropped.
When the variation concerns the spelling of the stem, an entire paradigm is
added to the morphology. In figure 5, the misspelling kolapsa is being added to the
paradigm for kollapse ‘(to) collapse’. This error is made systematically throughout
the text and is probably intentional (not a typo), and it is also likely to be a common
mistake. The word is added to the morphology by entering the base form of the
variant, kolapse, in the Base form field, and then typing in the base form of the
standard (Add to base form). All possible paradigms appear in the box to the right
(in this particular case only one) and the appropriate paradigm is chosen.
All extracted words are stored in a database together with their assigned lexical
properties and the context they were extracted from. Here, they can be reviewed and
reclassified/edited if necessary. Before the texts those words are extracted from are
added to the treebank and parsed, the extracted words and their paradigms have to be
added to the morphology used in the LFG grammar. Since this add-on morphology
is not technically merged with the main morphology, but compiled as a separate
transducer, the main morphological transducers do not have to be recompiled, and
updating of the add-on morphology is done in a matter of seconds.
