DOCIS-2022-09: Social Media Sentiment Analysis

The rapid development of the Internet and mobile devices, especially the upsurge of Web 2.0, has enabled the emergence of social media platforms that led to the creation of the field of research called ‘sentiment analysis’ to analyse this large-scale online resource of unstructured opinions. Sentiment analysis makes use of text analytics to capture public opinion. It is one of the most appealing use cases of Natural Language Processing (NLP), with interest from both industry and academia. Research nowadays embraces sentence-level subjectivity detection, aspect-based sentiment analysis, sentiment analysis on figurative language, topic-based polarity classification, classification of the implicit polarity of events, i.e. recognising “pleasant” or “unpleasant” circumstances when no straight polarity marker is mentioned, emotion classification, and more recently, stance detection and argument mining, all on a wide variety of languages and diversified media. Task definitions have evolved towards more complex challenges where subjectivity, polarity recognition, and opinion mining have enriched fine-grained aspects and topic-level predictions. Research challenges nowadays cover the following main topics: a) Aspect Based Sentiment Analysis, aimed at capturing the sentiments expressed on different aspects of entities such as products, movies, companies, etc., on user-generated comments; b) Emotion Analysis, aiming at detecting and recognising types of feelings in texts, such as anger, disgust, fear, happiness, sadness, and surprise; c) Spam and Fake Detection: to detect and analyse fake reviews and fake news which are closely related phenomena, as both consist of writing and spreading false information or beliefs, looking for efficient ways to tell the difference between an honest review and a fake one; d) Multimodal Sentiment Analysis, aiming at integrating into research the different social multimedia as multi-modal sentiment analysis that will bring new opportunities by embracing other, complementary data streams such as facial and vocal displays and expressions that express sentiment often in a compelling way.

DOCIS-2022-10: Digital Phenotyping-based Mental Health Analytics

Mental health problems are common in older people and can include anxiety and dementia. Many older people also suffer from sleep and behavioural problems, cognitive decline, and confusion. Often, patients cannot recognize the problem themselves, resulting in the condition being discovered very late. The term “digital phenotype” refers to the use of data from personal digital devices to quantify social, physical, cognitive, emotional, and behavioural phenotypes at the individual level. It is a powerful tool to better understand patients for scientific or clinical purposes. At USJ we foster research mental health analytics procedures based on a systematic analysis of multimodal data captured from various sources (sensors, GPS, cameras, text, and speech, etc.), as well as smartphones and other devices to study their relationship to the user’s psychological, emotional, and behavioural conditions. This research area embraces, statistical, machine learning, and deep learning algorithms that will be developed to facilitate disease detection, monitoring, and clinical support of user mental health. The goal of is to enable accurate and early detection of mental health problems, especially in seniors, to provide better medical support and improve their quality of life.

DOCIS-2022-11: Technology Acceptance Studies

New technologies (e.g., autonomous electric vehicles, internet of things (IoT) products, smart home systems, wearable devices, blockchain applications, etc.) are reshaping everyday life. But why are some technologies spreading faster than others? Some innovations have struggled to gain acceptance in society, even if they are arguably better than the current ones. Diffusion of Innovations (Rogers, 1962), Technology Acceptance Model (TAM; Davis, 1986), and Unified Theory of Acceptance and Use of Technology (UTAUT; Venkatesh et al., 2003) are well-accepted frameworks that have attempted to explain why individuals accept and use innovations, however many areas of research are still lacking. At USJ, the research’s primary goal is to apply established models to study how individuals or organisations accept and use emerging technologies by applying quantitative and statistical tools (i.e., structural equation modelling) to analyse the collected data.

DOCIS-2022-13: Biocompatible Communications in Healthcare Wearables

The elderly care solutions revolve around the home safety of the elderly, life care, abnormality monitoring, and timely treatment. Regarding medical treatment, health, security, and life enhancement for the elderly, wearable technology has stepped forward immensely into smart elderly care, interacting with the elder in every aspect and shaping the elder’s new lifestyle that technology brings. Wearable technology for healthcare can be defined as one that has intelligence and can give and receive input and provide meaningful output. It provides a valuable monitoring tool for healthcare. For some time, it has brought us unique challenges since wearable devices and electronics for healthcare present a unique interface of technology and person that needs to account both for technological and personal aspects of the problem. Communications from the body to the outside world and communications among multiple wearables on the body demand new solutions. Traditional radio methods experience challenges due to absorption by body tissue. The related challenges include the development of efficient methods for communicating through or on the body, including the organisation of wearables in body sensor networks and their integration into the Internet of Things. We can explore the following issues: 1) Can a future wearable communicate with other smartphones and tablets? 2) Can we consider the elder’s body as the communication medium for exchanging information with another wearable?
