Exploring Local and Global Semantic Information for Event Pronoun Resolution
نویسندگان
چکیده
Event anaphora resolution plays a critical role in discourse analysis. This paper focuses on improving event pronoun resolution using both local and global semantic information. In particular, a predicate-argument structure is proposed to represent the local semantic information about an event while the global semantic information is represented by the entity coreference chains related with various arguments in the predicate-argument structure to complement its locality. Evaluation on the OntoNotes English corpus shows the effectiveness of local and global semantic information for event pronoun resolution.

A Deep Neural Network for Chinese Zero Pronoun Resolution
Existing approaches for Chinese zero pronoun resolution overlook semantic information. This is because zero pronouns have no descriptive information, which results in difficulty in explicitly capturing their semantic similarities with antecedents. Moreover, when dealing with candidate antecedents, traditional systems simply take advantage of the local information of a single candidate anteceden...
متن کاملA Deep Neural Network for Chinese Zero Pronoun Resolution
This paper investigates the problem of Chinese zero pronoun resolution. Most existing approaches are based on machine learning algorithms, using hand-crafted features, which is labor-intensive. Moreover, semantic information that is essential in the resolution of noun phrases has not been addressed enough by previous approaches on zero pronoun resolution. This is because that zero pronouns have...
متن کاملImproving Japanese Zero Pronoun Resolution by Global Word Sense Disambiguation
This paper proposes unsupervised word sense disambiguation based on automatically constructed case frames and its incorporation into our zero pronoun resolution system. The word sense disambiguation is applied to verbs and nouns. We consider that case frames define verb senses and semantic features in a thesaurus define noun senses, respectively, and perform sense disambiguation by selecting th...
متن کاملEmploying the Centering Theory in Pronoun Resolution from the Semantic Perspective
In this paper, we employ the centering theory in pronoun resolution from the semantic perspective. First, diverse semantic role features with regard to different predicates in a sentence are explored. Moreover, given a pronominal anaphor, its relative ranking among all the pronouns in a sentence, according to relevant semantic role information and its surface position, is incorporated. In parti...
متن کاملImprove Tree Kernel-Based Event Pronoun Resolution with Competitive Information
Event anaphora resolution plays a critical role in discourse analysis. This paper proposes a tree kernel-based framework for event pronoun resolution. In particular, a new tree expansion scheme is introduced to automatically determine a proper parse tree structure for event pronoun resolution by considering various kinds of competitive information related with the anaphor and the antecedent can...
