Anaphora Resolution as Lexical Cohesion Identification
نویسندگان
چکیده
Anaphora, an important indicator in lexical cohesion, is a discourse level linguistic phenomenon. Most theoretical linguistic approaches to the interpretation of anaphoric expressions propose a treatment on the basis of purely syntactic information. In this article, what we proposed is to cast anaphora resolution as a semantic inference process in which combination of multiple strategies, each exploiting a different linguistic knowledge, is employed to resolve anaphora into a coherent one. We also exhibit how to embed an anaphora resolution into a framework which captures all the salient parameters as well as to remedy, to a certain extent, the inadequacies found in any monolithic resolution systems. The effectiveness of the anaphora resolution considered in this work is exemplified through a set of simulations.

Pronoun Resolution and Summary Extraction From English Documents
This paper presents an approach to generate a precise and meaningful summary of a Document in English Language. Here, we adopt a modified Sidner’s Focusing algorithm to perform pronoun resolution. We devise an algorithm to divide any sort of compound and complex sentences into simple sentences. Anaphora resolution is performed on these simple sentences. Then we find the lexical cohesion between...
متن کاملComputing Lexical Cohesion as a Tool for Text Analysis
Recognizing coherent structure of a text is an essential task in natural language understanding. It is necessary, for example, to resolve anaphora, ellipsis, and ambiguity. One of the dominant factors of coherence of the text structure is lexical cohesion, namely the dependency relationship between words based on associative relations in common knowledge. This thesis proposes an objective and c...
متن کاملText Segmentation Based on Similarity between Words
This paper proposes a new indicator of text structure, called the lexical cohesion pro le (LCP), which locates segment boundaries in a text. A text segment is a coherent scene; the words in a segment are linked together via lexical cohesion relations. LCP records mutual similarity of words in a sequence of text. The similarity of words, which represents their cohesiveness, is computed using a s...
متن کاملA Probabilistic Model for Associative Anaphora Resolution
This paper proposes a probabilistic model for associative anaphora resolution in Japanese. Associative anaphora is a type of bridging anaphora, in which the anaphor and its antecedent are not coreferent. Our model regards associative anaphora as a kind of zero anaphora and resolves it in the same manner as zero anaphora resolution using automatically acquired lexical knowledge. Experimental res...
متن کاملA Discriminative Approach to Japanese Zero Anaphora Resolution with Large-scale Lexicalized Case Frames
We present a discriminative model for Japanese zero anaphora resolution that simultaneously determines an appropriate case frame for a given predicate and its predicate-argument structure. Our model is based on a log linear framework, and exploits lexical features obtained from a large raw corpus, as well as non-lexical features obtained from a relatively small annotated corpus. We report the r...
