The importance of explaining the outcome of a machine learning model, especially a black-box model, is widely acknowledged.

Assessing Social License to Operate from the Public Discourse on Social Media

no code implementations COLING 2020 Chang Xu, Cecile Paris, Ross Sparks, Surya Nepal, Keith VanderLinden

Our experimental results show that SIRTA is highly effective in distilling stances from social posts for SLO level assessment, and that the continuous monitoring of SLO levels afforded by SIRTA enables the early detection of critical SLO changes.

Deep Learning for Community Detection: Progress, Challenges and Opportunities

1 code implementation17 May 2020 Fanzhen Liu, Shan Xue, Jia Wu, Chuan Zhou, Wenbin Hu, Cecile Paris, Surya Nepal, Jian Yang, Philip S. Yu

As communities represent similar opinions, similar functions, similar purposes, etc., community detection is an important and extremely useful tool in both scientific inquiry and data analytics.

An Effective Transition-based Model for Discontinuous NER

1 code implementation ACL 2020 Xiang Dai, Sarvnaz Karimi, Ben Hachey, Cecile Paris

Unlike widely used Named Entity Recognition (NER) data sets in generic domains, biomedical NER data sets often contain mentions consisting of discontinuous spans.

DAN: Dual-View Representation Learning for Adapting Stance Classifiers to New Domains

no code implementations13 Mar 2020 Chang Xu, Cecile Paris, Surya Nepal, Ross Sparks, Chong Long, Yafang Wang

We address the issue of having a limited number of annotations for stance classification in a new domain, by adapting out-of-domain classifiers with domain adaptation.

Image Captioning using Facial Expression and Attention

no code implementations8 Aug 2019 Omid Mohamad Nezami, Mark Dras, Stephen Wan, Cecile Paris

An analysis of the generated captions finds that, perhaps unexpectedly, the improvement in caption quality appears to come not from the addition of adjectives linked to emotional aspects of the images, but from more variety in the actions described in the captions.

Towards Generating Stylized Image Captions via Adversarial Training

no code implementations8 Aug 2019 Omid Mohamad Nezami, Mark Dras, Stephen Wan, Cecile Paris, Len Hamey

While most image captioning aims to generate objective descriptions of images, the last few years have seen work on generating visually grounded image captions which have a specific style (e. g., incorporating positive or negative sentiment).

Figurative Usage Detection of Symptom Words to Improve Personal Health Mention Detection

no code implementations ACL 2019 Adith Iyer, Aditya Joshi, Sarvnaz Karimi, Ross Sparks, Cecile Paris

The introduction of figurative usage detection results in an average improvement of 2. 21% F-score of personal health mention detection, in the case of the feature augmentation-based approach.

Survey of Text-based Epidemic Intelligence: A Computational Linguistic Perspective

no code implementations14 Mar 2019 Aditya Joshi, Sarvnaz Karimi, Ross Sparks, Cecile Paris, C Raina MacIntyre

Epidemic intelligence deals with the detection of disease outbreaks using formal (such as hospital records) and informal sources (such as user-generated text on the web) of information.

Senti-Attend: Image Captioning using Sentiment and Attention

no code implementations24 Nov 2018 Omid Mohamad Nezami, Mark Dras, Stephen Wan, Cecile Paris

However, such models typically have difficulty in balancing the semantic aspects of the image and the non-factual dimensions of the caption; in addition, it can be observed that humans may focus on different aspects of an image depending on the chosen sentiment or style of the caption.

Automatic Recognition of Student Engagement using Deep Learning and Facial Expression

3 code implementations7 Aug 2018 Omid Mohamad Nezami, Mark Dras, Len Hamey, Deborah Richards, Stephen Wan, Cecile Paris

This paper presents a deep learning model to improve engagement recognition from images that overcomes the data sparsity challenge by pre-training on readily available basic facial expression data, before training on specialised engagement data.

Facial Expression Recognition

Cross-Target Stance Classification with Self-Attention Networks

1 code implementation ACL 2018 Chang Xu, Cecile Paris, Surya Nepal, Ross Sparks

In stance classification, the target on which the stance is made defines the boundary of the task, and a classifier is usually trained for prediction on the same target.
