Identify Event Causality with Knowledge and Analogy

چکیده
Event causality identification (ECI) aims to identify the causal relationship between events, which plays a crucial role in deep text understanding. Due diversity of real-world events and difficulty obtaining sufficient training data, existing ECI approaches have poor generalizability struggle relation seldom seen events. In this paper, we propose utilize both external knowledge internal analogy improve ECI. On one hand, commonsense graph called ConceptNet enrich description an event sample reveal commonalities or associations different other retrieve similar as exam- ples glean useful experiences from such analogous neigh- bors better new pair. By understanding through exter- nal making with can alleviate data sparsity issue model gener- alizability. Extensive evaluations on two benchmark datasets show that our outperforms baseline methods by around 18% F1-value average

متن کاملCausality and Objectivity: The Arguments in Kant’s Second Analogy
Of the philosophical problems that Kant sets out to resolve in the Critique of Pure Reason, one of the foremost is how to justify the principle that, necessarily and universally, all events in the world occur because of an antecedent cause. This problem was, after all, the focal point of Kant’s intellectual engagement with Hume, and it served as an impetus for his transcendental idealist system...
متن کاملRevising Domain Knowledge with Cross-Domain Analogy
AI systems and human novices share a difficult problem: repairing incorrect models to improve expertise. For people, the use of analogies during instruction can augment the repair of science knowledge. Enabling AI systems to do the same involves several challenges: representing knowledge in commonsense science domains, constructing analogies to transfer knowledge, and flexibly revising domain k...
متن کاملImproving Event Causality Recognition with Multiple Background Knowledge Sources Using Multi-Column Convolutional Neural Networks
We propose a method for recognizing such event causalities as “smoke cigarettes” → “die of lung cancer” using background knowledge taken from web texts as well as original sentences from which candidates for the causalities were extracted. We retrieve texts related to our event causality candidates from four billion web pages by three distinct methods, including a why-question answering system,...
متن کاملMinimally Supervised Event Causality Identification
This paper develops a minimally supervised approach, based on focused distributional similarity methods and discourse connectives, for identifying of causality relations between events in context. While it has been shown that distributional similarity can help identifying causality, we observe that discourse connectives and the particular discourse relation they evoke in context provide additio...
