DeepBlues@LT-EDI-ACL2022: Depression level detection modelling through domain specific BERT and short text Depression classifiers

no code implementations LTEDI (ACL) 2022 Nawshad Farruque, Osmar Zaiane, Randy Goebel, Sudhakar Sivapalan

In addition we can use short text classifiers to extract relevant text from the long text and achieve slightly better accuracy, albeit, trading off with the processing time for extracting such excerpts.

Deep Temporal Modelling of Clinical Depression through Social Media Text

no code implementations28 Oct 2022 Nawshad Farruque, Randy Goebel, Sudhakar Sivapalan, Osmar R. Zaïane

We describe the development of a model to detect user-level clinical depression based on a user's temporal social media posts.

Depression Symptoms Modelling from Social Media Text: A Semi-supervised Learning Approach

no code implementations6 Sep 2022 Nawshad Farruque, Randy Goebel, Sudhakar Sivapalan, Osmar Zaiane

In our work, we describe a Semi-supervised Learning (SSL) framework which uses an initial supervised learning model that leverages 1) a state-of-the-art large mental health forum text pre-trained language model further fine-tuned on a clinician annotated DSD dataset, 2) a Zero-Shot learning model for DSD, and couples them together to harvest depression symptoms related samples from our large self-curated Depression Tweets Repository (DTR).

STEP-EZ: Syntax Tree guided semantic ExPlanation for Explainable Zero-shot modeling of clinical depression symptoms from text

no code implementations21 Jun 2021 Nawshad Farruque, Randy Goebel, Osmar Zaiane, Sudhakar Sivapalan

We focus on exploring various approaches of Zero-Shot Learning (ZSL) and their explainability for a challenging yet important supervised learning task notorious for training data scarcity, i. e. Depression Symptoms Detection (DSD) from text.
