SemDaX

The SemDax Corpus is a Danish human-annotated corpus relying on the combined wordnet and dictionary resources: DanNet and Den Danske Ordbog, and available through a CLARIN academic license. The corpus includes approx. 90,000 words, comprises six textual domains, and is annotated with sense inventories of different granularity. All nouns, verbs and adjectives in the corpus were annotated with supersenses (all-words task). Furthermore, 20 very polysemous nouns were annotated with all the senses from the Den Danske Ordbog and a reduced set of clustered senses respectively.

The aim of the developed corpus is twofold: i) to assess the reliability of the different sense annotation schemes for Danish measured by qualitative analyses and annotation agreement scores, and ii) to serve as training and test data for machine learning algorithms with the practical purpose of developing sense taggers for Danish.

To these aims, we take a new approach to human-annotated corpus resources by double annotating a much larger part of the corpus than what is normally seen: for the all-words task we double annotated 60% of the material and for the lexical sample task 100%. We include in the corpus not only the curated files, but also the diverging annotations. In other words, we consider not all disagreement to be noise, but rather to contain valuable linguistic information that can help us improve our annotation schemes and our learning algorithms.
