Incremental Event Detection via Knowledge Consolidation Networks

2020

Conventional approaches to event detection usually require a fixed set of pre-defined event types. Such a requirement is often challenged in real-world applications, as new events continually occur. Due to huge computation cost and storage …

Distant Supervision for Relation Extraction via Piecewise Convolutional Neural Networks

2015

Two problems arise when using distant supervision for relation extraction. First, in this method, an already existing knowledge base is heuristically aligned to texts, and the alignment results are treated as labeled data. However, the …

Exploiting Argument Information to Improve Event Detection via Supervised Attention Mechanisms

2017

This paper tackles the task of event detection (ED), which involves identifying and categorizing events. We argue that arguments provide significant clues to this task, but they are either completely ignored or exploited in an …

Collective Event Detection via a Hierarchical and Bias Tagging Networks with Gated Multi-level Attention Mechanisms

2018

Traditional approaches to the task of ACE event detection primarily regard multiple events in one sentence as independent ones and recognize them separately by using sentence-level information. However, events in one sentence are usually interdependent …

Adversarial Transfer Learning for Chinese Named Entity Recognition with Self-Attention Mechanism

2018

Named entity recognition (NER) is an important task in natural language processing area, which needs to determine entities boundaries and classify them into pre-defined categories. For Chinese NER task, there is only a very small …

Knowledge Enhanced Event Causality Identification with Mention Masking Generalizations

2020

Identifying causal relations of events is a crucial language understanding task. Despite many efforts for this task, existing methods lack the ability to adopt background knowledge, and they typically generalize poorly to new, previously unseen …

Event Extraction as Machine Reading Comprehension

2020

Event extraction (EE) is a crucial information extraction task that aims to extract event information in texts. Previous methods for EE typically model it as a classification task, which are data-hungry and suffer from the …
