Abductive Coreference by Model Construction

چکیده
In this paper, we argue that the resolution of anaphoric expressions in an utterance is essentially an abductive task following [HSAM93] who use a weighted abduction scheme on horn clauses to deal with reference. We give a semantic representation for utterances containing anaphora that enables us to compute possible antecedents by abductive inference. We extend the disjunctive model construction procedure of hyper tableaux [BFN96, Küh97] with a clause transformation turning the abductive task into a model generation problem and show the completeness of this transformation with respect to the computation of abuctive explanations. This abductive inference is applied to the resolution of anaphoric expressions in our general model constructing framework for incremental discourse representation [Küh99] which we argue to be useful for computing information updates from natural language utterances [Vel96].

متن کاملCoreference Resolution with ILP-based Weighted Abduction
This paper presents the first systematic study of the coreference resolution problem in a general inference-based discourse processing framework. Employing the mode of inference called weighted abduction, we propose a novel solution to the overmerging problem inherent to inference-based frameworks. The overmerging problem consists in erroneously assuming distinct entities to be identical. In di...
متن کاملWhat Kind of Proof Can Be Constructed following an Abductive Argumentation?
My interests focus on the comparison between the abductive argumentation supporting a conjecture and the related proof. In particular, .the purpose of my research is to show the importance of a structural analysis between them (from an abductive argumentation to a deductive proof, from an abductive argumentation to an abductive “proof”). I propose the Toulmin’s model as a tool which can be used...
متن کاملDistantly Labeling Data for Large Scale Cross-Document Coreference
Cross-document coreference, the problem of resolving entity mentions across multi-document collections, is crucial to automated knowledge base construction and data mining tasks. However, the scarcity of large labeled data sets has hindered supervised machine learning research for this task. In this paper we develop and demonstrate an approach based on “distantly-labeling” a data set from which...
متن کاملJoint Inference for Event Timeline Construction
This paper addresses the task of constructing a timeline of events mentioned in a given text. To accomplish that, we present a novel representation of the temporal structure of a news article based on time intervals. We then present an algorithmic approach that jointly optimizes the temporal structure by coupling local classifiers that predict associations and temporal relations between pairs o...
