Representation and Pre-Activation of Lexical-Semantic Knowledge in Neural Language Models

no code implementations NAACL (CMCL) 2021 Steven Derby, Paul Miller, Barry Devereux

Furthermore, in order to make more meaningful comparisons with theories of human language comprehension in psycholinguistics, we focus on two key stages where the meaning of a particular target word may arise: immediately before the word’s presentation to the model (comparable to forward inferencing), and immediately after the word token has been input into the network.

Deep Learning Proteins using a Triplet-BERT network

no code implementations1 Jan 2021 Mark Lennox, Neil M. Robertson, Barry Devereux

Modern sequencing technology has produced a vast quantity of proteomic data, which has been key to the development of various deep learning models within the field.

Modelling Drug-Target Binding Affinity using a BERT based Graph Neural network

no code implementations1 Jan 2021 Mark Lennox, Neil M. Robertson, Barry Devereux

In this paper, we seek to leverage a set of BERT-style models that have been pre-trained on vast quantities of both protein and drug data.

Encoding Lexico-Semantic Knowledge using Ensembles of Feature Maps from Deep Convolutional Neural Networks

no code implementations COLING 2020 Steven Derby, Paul Miller, Barry Devereux

Semantic models derived from visual information have helped to overcome some of the limitations of solely text-based distributional semantic models.

Analysing Word Representation from the Input and Output Embeddings in Neural Network Language Models

1 code implementation CONLL 2020 Steven Derby, Paul Miller, Barry Devereux

Researchers have recently demonstrated that tying the neural weights between the input look-up table and the output classification layer can improve training and lower perplexity on sequence learning tasks such as language modelling.

Does History Matter? Using Narrative Context to Predict the Trajectory of Sentence Sentiment

no code implementations LREC 2020 Liam Watson, Anna Jurek-Loughrey, Barry Devereux, Brian Murphy

Previous work in the area of sentiment analysis has focused on using information from within a sentence to predict a valence value for that sentence.

Feature2Vec: Distributional semantic modelling of human property knowledge

1 code implementation IJCNLP 2019 Steven Derby, Paul Miller, Barry Devereux

We propose a method for mapping human property knowledge onto a distributional semantic space, which adapts the word2vec architecture to the task of modelling concept features.

Analysing Representations of Memory Impairment in a Clinical Notes Classification Model

no code implementations WS 2019 Mark Ormerod, Jes{\'u}s Mart{\'\i}nez-del-Rinc{\'o}n, Neil Robertson, Bernadette McGuinness, Barry Devereux

Despite recent advances in the application of deep neural networks to various kinds of medical data, extracting information from unstructured textual sources remains a challenging task.

Using Sparse Semantic Embeddings Learned from Multimodal Text and Image Data to Model Human Conceptual Knowledge

no code implementations CONLL 2018 Steven Derby, Paul Miller, Brian Murphy, Barry Devereux

In this paper, we combine multimodal information from both text and image-based representations derived from state-of-the-art distributional models to produce sparse, interpretable vectors using Joint Non-Negative Sparse Embedding.
