Clustering step in the mention-pair paradigm for coreference resolution, forms the chain of coreferent mentions from the mention pairs classified as coreferent. Clustering methods including best-first clustering considers each antecedent candidate individually, while selecting the antecedent for an anaphoric mention. Here we introduce an easyto-implement modification to best-first clustering to...

Introduction Anaphora has an important function in text comprehension. The processes of anaphoric inference are to make local coherence among sentences. The coherence constructed from several variables (e.g. Lee, 1993). The first variable is an anaphora type: noun phrase, pronoun or ellipsis. Another variable is the properties of antecedents: syntactic, semantic, or pragmatic. Yet another varia...

In this paper, we focus on the way how the rhetorical discourse structure of texts, in terms of coherence relations, and different types of referring expressions depend on each other. In particular, we concentrate on the impact the resolution of anaphora has on the derivation of coherence relations. We introduce an algorithm which combines such analyses and provide a preliminary evaluation of i...

We evaluated the predictions of Grosz and Sidner’s theory of anaphoric accessibility using a corpus of tutorial dialogues whose discourse structure was annotated according to Relational Discourse (RDA) Analysis. We found support for Moser and Moore’s proposal that only segments with an intentional core should be viewed as introducing new focus spaces; we also found that both embedded cores and ...

This paper describes the use of a Bayesian network to resolve anaphora by probabilistically combining linguistic evidence. By adopting a Bayesian approach, we are able to combine diverse evidence in a principled way, extend current understanding of linguistic phenomena by quantifying relationships empirically, and better model the non-deterministic role of linguistic evidence in resolution of a...

The Live Memories corpus is an Italian corpus annotated for anaphoric relations. The corpus includes manual annotated information about morphosyntactic agreement, anaphoricity, and semantic class of the NPs. For the annotation of the anaphoric links the corpus takes into account specific phenomena of the Italian language like incorporated clitics and phonetically non realized pronouns. The Live...
