How to Deal with Wicked Anaphora

This paper revises a framework (called AR-engine) capable of easily defining and operating models of anaphora resolution. The proposed engine envisages the linguistic and semantic entities involved in the cognitive process of anaphora resolution as represented in three layers: the referential expressions layer, the projected layer of referential expression’s features and the semantic layer of discourse entities. Within this framework, cases of anaphora resolution usually considered difficult to be tackled are investigated and solutions are proposed. Among them, one finds relations triggered by syntactic constraints, lemma and number disagreement, and bridging anaphora. The investigation uses a contiguous text from the belletrist register. The research is motivated by the view that interpretation of free language in modern applications, especially those related to the semantic web, requires more and more sophisticated tools.
