6. A description of the heuristics same-clauseThe candidate is in the same clause preceding-clauseThe candidate is in the preceding clause pre-preceding-clauseThe candidate is in any clause in the given sentence farther back than the preceding clause. preceding-sentThe candidate is in the preceding sentence. sentence-minus-2The candidate is two sentences back. sentence-minus-3The candidate is three sentences back. para-breakThe candidate is in the preceding paragraph. Valid only for candidates that, themselves, are not in the first sentence of a paragraph. repeat-collocationThe nominal candidate has been the same argument of the given verb previously. syn-collocationThe nominal candidate has been the same argument of a synonymous (or similar) verb previously. agent-themeThe nominal candidate is one of the main arguments in its clause, which we can define for now as the agent or theme (not path, beneficiary, instrument, etc.) pp-embeddedThe nominal candidate is embedded in a PP (this is mostly to weed out non- prominent adjuncts, but since some arguments are PPs, it can't be too strong a heuristic; it is better to look at case roles).

7. function-matchThe syntactic function of the candidate matches the function of the referring expression coordThe candidate is an argument in the preceding conjunct of a coordinate structure BUT the coordinate structure must be larger than the category itself:i.e., we want to catch the fact that the coordination in 'I picked up the book and read it' (VP coordination) is a strong indicator of coreference, but we don't want to assume that there is coreference in 'I told John and him'. refl-null-semThe reflexive directly follows a NP that has matching features; in this case, it is rendered as null semantics (I myself know… He himself thought… The plans themselves are …) subj-of-same-clauseThe candidate is the head of the subject of the same clause (used to distinguish anaphors). By 'subject of same clause' we mean whichever of the following is the nearest: 1) the overt or elided subject of the minimal tensed clause - Mary-i likes herself-i. - Mary-i is happy-go-lucky and pro-i likes herself-i 2) the PRO (non-overt) subject of the given infinitival clause - John-i forces his children-j PRO-j to fight for themselves-j 3) the overt PP "subject" of the given infinitival clause - For me-i to hurt myself-i would be stupid. It's important to say 'the head' of the subject because, for example, 'Mary's-i dog likes her-i' has coreference between the mod of the head and the d.o. refl-cl-subj The reflexive has to match features with the subject of the clause: He went to the movies himself
