Anaphora Resolution in Multi-Person Dialogues
نویسندگان
چکیده
Anaphora resolution for dialogues is a difficult problem because of the several kinds of complex anaphoric references generally present in dialogic discourses. It is nevertheless a critical first step in the processing of any such discourse. In this paper, we describe a system for anaphora resolution in multi-person dialogues. This system aims to bring together a wide array syntactic, semantic and world knowledge based techniques used for anaphora resolution. In this system, the performance of the heuristics is optimized for specific dialogues using genetic algorithms, which relieves the programmer of hand-crafting the weights of these heuristics. In our system, we propose a new technique based on the use of anaphora chains to enable resolution of a large variety of anaphors, including plural anaphora and cataphora.

Anaphora Resolution Using Extended Centering Algorithm In A Multi-Modal Dialogue System
Anaphora in multi-modal dialogues have different aspects compared to the anaphora in language-only dialogues. They often refer to the items signified by a gesture or by visual means. In this paper, we define two kinds of anaphora: screen anaphora and referring anaphora, and propose two general methods to resolve these anaphora. One is a simple mapping algorithm that can find items refetxed with...

Anaphora resolution is a central topic in dialogue and discourse processing that deals with finding the referents of pronouns. There are no studies, to the best of our knowledge, that focus on anaphora resolution in the context of tutorial dialogues. In this paper, we present the first version of DARE (Deep Anaphora Resolution Engine), an anaphora resolution engine for dialogue-based Intelligen...
متن کاملResolving Discourse Deictic Anaphora in Dialogues
Most existing anaphora resolution algorithms are designed to account only for anaphors with NP-antecedents. This paper describes an algorithm for the resolution of discourse deictic anaphors, which constitute a large percentage of anaphors in spoken dialogues. The success of the resolution is dependent on the classification of all pronouns and demonstratives into individual, discourse deictic a...

In this paper, we present an algorithm for anaphora resolution in Spanish dialogues and an evaluation of the algorithm for pronominal anaphora. The proposed algorithm uses both linguistic information and the structure of the dialogue to find the antecedent of the anaphors. The system has been evaluated on ten dialogues.

Anaphora resolution is a central topic in dialogue and discourse that deals with finding the referent of a pronoun. It plays a critical role in conversational Intelligent Tutoring Systems (ITSs) as it can increase the accuracy of assessing students’ mental model based on their natural language inputs. Although the task of anaphora resolution is one of the most studied problems in Natural Langua...
