Abstract

. We present a hybrid methodology for the resolution of functional anaphora. It incorporates conceptual proximity criteria applied to ontologically well-engineered domain knowledge bases and an approach to centering based on functional topic/comment patterns. We state grammatical predicates for functional anaphora and then turn to the procedural aspects of their evaluation within the framework of an actor-based implementation of a lexically distributed parser. 1 Introduction Text phenomena, e.g., textual forms of pronominal, nominal and functional anaphora, are a particularly challenging issue for the design of natural language parsers, since lacking recognition facilities either result in referentially incohesive or invalid text knowledge representations. At the conceptual level, functional anaphora relates an anaphoric expression to its antecedent by conceptual attributes (or roles) associated with that antecedent (see, e.g., the relation between "Zugriffszeit" (access time) and "S...
