(s, chunk_types=(u'NP', u'PP', u'VP'), root_label=u'S')[source]¶ Return a chunk structure for a single sentence encoded in the given CONLL 2000 style string. This function converts a CoNLL IOB string into a tree. It uses the specified chunk types (defaults to NP, PP and VP), and creates a tree rooted at a node labeled S (by default).
Parameters: - s (str) – The CoNLL string to be converted.
- chunk_types (tuple) – The chunk types to be converted.
- root_label (str) – The node label to use for the root.
