Detailed Description

Class mention is a node in the parse tree, as well as the sequence of tokens subsumed by the node.

(It is assumed that a depnode corresponds to a parse tree node)

constructor from start/end word iterators

fuzzy constructor from start/end positions the mention is created from start1 to end1 (start1 >= start and end1 <= end) [start1, end1] is the sequence closest to start with the maximal subsuming node ptree
