Statistical Anaphora Resolution Ben Handy, Tyler Hicks-Wright, Eric Schkufza
Anaphora Resolution • Given a body of text, anaphora resolution is the problem of associating pronouns with the nouns and noun phrases that they refer to. • “Mr. Harris finally arrived in Munich on Saturday afternoon after a lengthy delay in Rome. However, he did not meet Ms. Lewis until the following morning.”
Ge, Hale, Charniak, 1998 • A Statistical Approach to Anaphora Resolution • P(A(p) = a | p, h, W , t, l, sp, d, M) • Hobb’s Distance: P(dH = i | a) • Gender-Animaticity: P(p | wa) • Mention Count: P(a | ma, j) • Parse Probability: P(wa | h, t, l)
Handy, Hicks-Wright, Schkufza, 2006 • Ge’s probability can be interpreted as a score • Augment that score with: • Language Model score: rates substitutions based on their grammatical correctness. • MaxEnt based score: augments Ge’s gender-animaticity score.
