One-shot to Weakly-Supervised Relation Classification using Language Models

1 code implementation AKBC 2021 Thy Thy Tran, Phong Le, Sophia Ananiadou

Unfortunately, both annotation methodologies are costly and time-consuming since they depend on intensive human labour for annotation or for knowledge base creation.

DoLFIn: Distributions over Latent Features for Interpretability

no code implementations COLING 2020 Phong Le, Willem Zuidema

Interpreting the inner workings of neural models is a key step in ensuring the robustness and trustworthiness of the models, but work on neural network interpretability typically faces a trade-off: either the models are too constrained to be very useful, or the solutions found by the models are too complex to interpret.

Revisiting Unsupervised Relation Extraction

1 code implementation ACL 2020 Thy Thy Tran, Phong Le, Sophia Ananiadou

Unsupervised relation extraction (URE) extracts relations between named entities from raw text without manually-labelled data and existing knowledge bases (KBs).

Distant Learning for Entity Linking with Automatic Noise Detection

1 code implementation ACL 2019 Phong Le, Ivan Titov

As the learning signal is weak and our surrogate labels are noisy, we introduce a noise detection component in our model: it lets the model detect and disregard examples which are likely to be noisy.

Entity Linking

Improving Entity Linking by Modeling Latent Relations between Mentions

2 code implementations ACL 2018 Phong Le, Ivan Titov

Entity linking involves aligning textual mentions of named entities to their corresponding entries in a knowledge base.

Entity Linking

Optimizing Differentiable Relaxations of Coreference Evaluation Metrics

1 code implementation CONLL 2017 Phong Le, Ivan Titov

Coreference evaluation metrics are hard to optimize directly as they are non-differentiable functions, not easily decomposable into elementary decisions.

LSTM-based Mixture-of-Experts for Knowledge-Aware Dialogues

no code implementations WS 2016 Phong Le, Marc Dymetman, Jean-Michel Renders

We introduce an LSTM-based method for dynamically integrating several word-prediction experts to obtain a conditional language model which can be good simultaneously at several subtasks.

Quantifying the vanishing gradient and long distance dependency problem in recursive neural networks and recursive LSTMs

no code implementations WS 2016 Phong Le, Willem Zuidema

Recursive neural networks (RNN) and their recently proposed extension recursive long short term memory networks (RLSTM) are models that compute representations for sentences, by recursively combining word embeddings according to an externally provided parse tree.

Unsupervised Dependency Parsing: Let's Use Supervised Parsers

no code implementations HLT 2015 Phong Le, Willem Zuidema

We present a self-training approach to unsupervised dependency parsing that reuses existing supervised and unsupervised parsing algorithms.

Unsupervised Dependency Parsing

Compositional Distributional Semantics with Long Short Term Memory

1 code implementation SEMEVAL 2015 Phong Le, Willem Zuidema

We are proposing an extension of the recursive neural network that makes use of a variant of the long short-term memory architecture.
