Understanding the output

Question

@mandarjoshi90 @jkkummerfeld
New to coreference resolution. Still exploring, learning the coreference output, and understanding the parameters.

I tried finding several resources but could find an explanation for the output.

GIven the following i/p, I appreciate it if someone could explain the o/p and how to infer the press.

Input

sentence = [Paul Allen was born on January 21, 1953, in Seattle, Washington, to Kenneth Sam Allen and Edna Faye Allen.,
Allen attended Lakeside School, a private school in Seattle, where he befriended Bill Gates, two years younger, with whom he shared an enthusiasm for computers.,
Paul and Bill used a teletype terminal at their high school, Lakeside, to develop their programming skills on several time-sharing computer systems.]

Output:

[((0, 2), 'Paul Allen'), ((19, 20), 'Allen'), ((29, 30), 'he'), ((38, 39), 'he'), ((44, 45), 'Paul')],

For an introduction to the task, see this chapter from Dan Jurafsky's book:

The output you have shows clusters and mentions, with numbers for token positions in the text (Python style slices, so (0, 2) gives you the first two tokens).
