Multiword expressions in the Prague Dependency Treebank 2.0
Annotation of Multiword Expressions and Multiword Named Entities in the PDT 2.0
The Prague Dependency Treebank 2.0 (PDT 2.0) contains a large amount of Czech texts with complex and interlinked morphological (2 million words), syntactic (1.5 MW) and complex semantic annotation (0.8 MW); in addition, certain properties of sentence information structure and coreference relations are annotated at the semantic level.
This dataset adds annotation of multiword expressions and multiword named entities to the original PDT 2.0 data. The annotation is stand-off, stored in the same PML format as the original PDT 2.0 data. It is to be used together with the PDT 2.0.
There is also a tectogrammatical MWE lexicon SemLex: lexicon of all the MWEs annotated. The lexicon is a work in progress: It is complete in terms of coverage of the data. All the entries also include the basic form of the expressions, a simplified dependency structure, and some other attributes. On the other hand only a few entries have a proper gloss, example sentence, synonyms (if applicable) and some other attributes.
