Method __init__ Undocumented
Method categ Undocumented
Method dot Return this edge's dot position, which indicates how much of the hypothesized structure is consistent with the sentence. In particular, self.rhs[:dot] is consistent with tokens[self.start():self.end()]...
Method end Return the end index of this edge's span.
Method is_complete Return True if this edge's structure is fully consistent with the text.
Method is_incomplete Return True if this edge's structure is partially consistent with the text.
Method length Return the length of this edge's span.
Method lhs Return this edge's left-hand side, which specifies what kind of structure is hypothesized by this edge.
Method nextsym Return the element of this edge's right-hand side that immediately follows its dot.
Method rhs Return this edge's right-hand side, which specifies the content of the structure hypothesized by this edge.
Method rule Undocumented
Method span Return a tuple (s, e), where tokens[s:e] is the portion of the sentence that is consistent with this edge's structure.
Method start Return the start index of this edge's span.
