Coreference Systems based on Kernels Methods

摘要

Various types of structural information -e.g., about the type of constructions in which binding constraints apply, or about the structure of names - play a central role in coreference resolution, often in combination with lexical information (as in expletive detection). Kernel functions appear to be a promising candidate to capture structure-sensitive similarities and complex feature combinations, but care is required to ensure they are exploited in the best possible fashion. In this paper we propose kernel functions for three subtasks of coreference resolution - binding constraint detection, expletive identification, and aliasing - together with an architecture to integrate them within the standard framework for coreference resolution.
