CoNLL format

CoNLL format is a specific format of vertical that represents a syntactic parse tree. In comparison with vertical, there are extra columns describing the syntactic structure of words within the sentence, i.e. id, head, deprel. The number and position of these extra columns may vary depending on the specific CoNLL format.

  • id representing the positions of the current word (the 1st column)
  • head is the parent node id of the current word (the 5th column)
  • deprel contains the information about the relation by which the current node and parent node are connected (the 6th column)
