چکیده

We present a neural architecture for containment relation identification between medical events and/or temporal expressions. We experiment on a corpus of deidentified clinical notes in English from the Mayo Clinic, namely the THYME corpus. Our model achieves an F-measure of 0.613 and outperforms the best result reported on this corpus to date.

Neural Temporal Relation Extraction

We experiment with neural architectures for temporal relation extraction and establish a new state-of-the-art for several scenarios. We find that neural models with only tokens as input outperform state-ofthe-art hand-engineered feature-based models, that convolutional neural networks outperform LSTM models, and that encoding relation arguments with XML tags outperforms a traditional position-b...

Neural Architecture for Negative Opinion Expressions Extraction

Opinion expressions extraction is one of the main frameworks in opinion mining. Extracting negative opinions is more difficult than positive opinions because of indirect expressions. Especially, in the domain of consumer reviews, consumers are easier to be influenced by negative reviews when making decision. In this paper, we focus on the extraction of negative opinion expressions of consumer r...

Semantic Relation Classification by Bi-directional LSTM Architecture

Semantic relation extraction is a meaningful task in NLP that could provide some helpful information and semantic relation classification attracts many people to research it. This paper mainly introduces a Bi-direction LSTM (long short-term memory) deep neutral network and the parameter of embedding layer, and this network can solve the problem of over-fitting. And then according to the text of...

Simulating Player Behavior for Data-Driven Interactive Narrative Personalization

Data-driven approaches to interactive narrative personalization show significant promise for applications in entertainment, training, and education. A common feature of datadriven interactive narrative planning methods is that an enormous amount of training data is required, which is rarely available and expensive to collect from observations of human players. An alternative approach to obtaini...

A Convolutional Encoder Model for Neural Machine Translation

The prevalent approach to neural machine translation relies on bi-directional LSTMs to encode the source sentence. We present a faster and simpler architecture based on a succession of convolutional layers. This allows to encode the source sentence simultaneously compared to recurrent networks for which computation is constrained by temporal dependencies. On WMT’16 EnglishRomanian translation w...
