Parallel treebanks with annotation of syntax, discourse, coreference, morphology, and semantics. Version 3 also includes the Danish Dependency Treebank (version 1) and the Danish-English Parallel Dependency Treebank (version 2).
DTAG is a versatile annotation tool that supports manual and semi-automatic annotation of a wide range of linguistic phenomena, including the annotation of syntax, discourse, coreference, morphology, and word and phrase alignments. It includes commands for editing general labeled graphs and graph alignments, comparing annotations, managing annotation tasks, and interfacing with a revision control system. Its visualization component can display graphs and alignments for entire texts in a compact format, with a highly flexible and configurable formatting scheme. It also provides a powerful search-replace mechanism with queries based on full first-order logic, which can be used to search for linguistic constructions and automatically apply graph transformations to collections of annotated graphs. The visualization component does not currently support characters outside the ISO-latin character set.
