Chinese ellipsis resolution based on the HNC theory — A new approach to context formalization researches

In the NLP field, the mainstream practice in processing a text is through the syntactic and semantic analysis of its componential sentences. However, more and more researchers have come to realize that without the help of the context, difficulties like ambiguity, ellipsis and anaphora can hardly get really solved. In this paper a new approach of context formalization is introduced - the Context Frame, which is part of the Hierarchical Network of Concepts (HNC) theory. By comparing Conceptual Dependency (CD) theory, Frame Semantics and HNC Context Frame theory, we analyzed the advantages of the HNC theory in text processing, introduced the application of the theory, and at last we briefly introduced how Context Frame is used to resolve ellipses in Chinese texts.
