PubMed 200k RCT: a Dataset for Sequential Sentence Classification in Medical Abstracts

10 code implementations IJCNLP 2017 Franck Dernoncourt, Ji Young Lee

First, the majority of datasets for sequential short-text classification (i. e., classification of short texts that appear in sequences) are small: we hope that releasing a new large dataset will help develop more accurate algorithms for this task.

Transfer Learning for Named-Entity Recognition with Neural Networks

no code implementations LREC 2018 Ji Young Lee, Franck Dernoncourt, Peter Szolovits

In particular, we demonstrate that transferring an ANN model trained on a large labeled dataset to another dataset with a limited number of labels improves upon the state-of-the-art results on two different datasets for patient note de-identification.

Neural Networks for Joint Sentence Classification in Medical Paper Abstracts

5 code implementations EACL 2017 Franck Dernoncourt, Ji Young Lee, Peter Szolovits

Existing models based on artificial neural networks (ANNs) for sentence classification often do not incorporate the context in which sentences appear, and classify sentences individually.

Feature-Augmented Neural Networks for Patient Note De-identification

no code implementations WS 2016 Ji Young Lee, Franck Dernoncourt, Ozlem Uzuner, Peter Szolovits

In this work, we explore a method to incorporate human-engineered features as well as features derived from EHRs to a neural-network-based de-identification system.

Optimizing Neural Network Hyperparameters with Gaussian Processes for Dialog Act Classification

1 code implementation27 Sep 2016 Franck Dernoncourt, Ji Young Lee

Therefore it is a useful technique for tuning ANN models to yield the best performances for natural language processing tasks.

De-identification of Patient Notes with Recurrent Neural Networks

1 code implementation10 Jun 2016 Franck Dernoncourt, Ji Young Lee, Ozlem Uzuner, Peter Szolovits

It yields an F1-score of 97. 85 on the i2b2 2014 dataset, with a recall 97. 38 and a precision of 97. 32, and an F1-score of 99. 23 on the MIMIC de-identification dataset, with a recall 99. 25 and a precision of 99. 06.

Robust Dialog State Tracking for Large Ontologies

no code implementations7 May 2016 Franck Dernoncourt, Ji Young Lee, Trung H. Bui, Hung H. Bui

The Dialog State Tracking Challenge 4 (DSTC 4) differentiates itself from the previous three editions as follows: the number of slot-value pairs present in the ontology is much larger, no spoken language understanding output is given, and utterances are labeled at the subdialog level.
