dep: unspecified dependency

A dependency is labeled as dep when a system is unable to determine a more precise dependency relation between two words. This may be because of a weird grammatical construction, a limitation in software, a parser error, or because of an unresolved long distance dependency.

Most dep instances in the current conversion of the PDT 3.0 data correspond to the PDT label ExD, which marks ellipsis. The current conversion software cannot produce the annotation conforming to the UD standard and using the remnant relation.


Treebank Statistics (UD_Czech)

This relation is universal.

12570 nodes (1%) are attached to their parents as dep.

11290 instances of dep (90%) are left-to-right (parent precedes child). Average distance between parent and child is 4.26332537788385.
