With the increasing legalization of medical and recreational use of substances, more research is needed to understand the association between mental health and user behavior related to drug consumption. Specifically, drug overdose and substance use-related mental health issues have become two major topics that have been widely discussed on social media platforms. Big social media data has the potential to provide deeper insights about these associations to public health analysts for making policy decisions. Multiple national population surveys have found that about half of those who experience a mental health illness during their lives will also experience a substance use disorder and vice versa. The communications related to addiction and mental health are complex to process and understand given their language and contextual characteristics. Surface-level data analysis alone is not sufficient to understand the complex nature of relationships among the addiction and mental health context. Moreover, dark web vendors have been using social media as a new marketplace for drugs. Social media users also discuss the novel drugs emerging in dark web marketplaces and associated side effects/health conditions. These communications get complex when researchers try to annotate them or link them to a specific mental health entity. Considering the significant sensitivity of such communications and to protect user privacy on social media, a potential solution requires reliable algorithms for modeling such communications. We demonstrate the value of incorporating domain-specific knowledge in natural language understanding to identify the relationship between mental health and drug addiction. We discuss end-to-end knowledge-infused deep learning frameworks that leverage the pre-trained language representation model and domain-specific declarative knowledge source to extract entities and their relationships jointly. Our model is further tailored to focus on the entities mentioned in the sentence where ontology is used to locate the target entity’s position. We also demonstrate the capabilities of inclusion of the knowledge-aware representation in association with language models that can extract the Drug-Mental health condition associations.

Healthcare as we know it is in the process of going through a massive change – from episodic to continuous, from disease-focused to wellness and quality of life focused, from clinic centric to anywhere a patient is, from clinician controlled to patient empowered, and from being driven by limited data to 360-degree, multimodal personal-public-population physical-cyber-social big data-driven. While the ability to create and capture data is already here, the upcoming innovations will be in converting this big data into smart data through contextual and personalized processing such that patients and clinicians can make better decisions and take timely actions. The exploitation of all relevant data, relevant medical knowledge, and explainable AI techniques will also support better communications between patients, clinicians, and virtual health assistants with higher-level abstractions (rather than low-level data) representing health choices, decisions and actions.
Augmented Personalized Healthcare (APH) strategy we are developing empowers patients with self-monitoring (collecting relevant data), self-appraisal (interpreting data in the patient’s context), self-management (assisting the patient in following personalized care plan to maintain health), to intervention (when the clinical help is needed) and disease progression tracking and prediction (http://bit.ly/AI-APH, http://bit.ly/APH-TED). We currently apply APH using mobile Apps and virtual health assistants for patients managing pediatric asthma (http://bit.ly/kAsthma), mental health, carbohydrate management for type 1 diabetes, hypertension, etc. In this talk, I will describe some of the technical components that incorporate context, personalization, and abstraction for supporting advanced capabilities such as patient engagement through meaningful question generation, chatbot safety, and explainable decision-making using knowledge-infused learning, a neurosymbolic AI strategy that utilizes many types and levels of explicit knowledge.

Abstract:
Healthcare as we know it is in the process of going through a massive change - from episodic to continuous, from disease-focused to wellness and quality of life focused, from clinic centric to anywhere a patient is, from clinician controlled to patient empowered, and from being driven by limited data to 360-degree, multimodal personal-public-population physical-cyber-social big data-driven. While the ability to create and capture data is already here, the upcoming innovations will be in converting this big data into smart data through contextual and personalized processing such that patients and clinicians can make better decisions and take timely actions. The exploitation of all relevant data, relevant medical knowledge, and AI techniques will extend and enhance human health and well-being.
Augmented Personalized Healthcare (APH) strategy as we have defined involves empowering patients with self-monitoring (collecting relevant data), self-appraisal (interpreting data in the patient's context), self-management (assisting the patient in following personalized care plan to maintain health), to intervention (when the clinical help is needed) and disease progression tracking and prediction (http://bit.ly/AI-APH, http://bit.ly/APH-TED). While we have early investigations for several diseases, we will share some experience (such as developing a digital phenotype) from pediatric asthma that involved an evaluation with ~200 patients (http://bit.ly/kAsthma).

Asthma is a chronic multifactorial disease and traditional clinical practice requires patients to meet their clinician in a timely yet infrequently meetings scheduled once in 3-6 months depending on the patient’s condition. The clinical diagnosis relies on the patient’s description of their current health condition. The patient’s description need not be accurate at times and may lack some important aspects needed for accurate diagnosis. We at Kno.e.sis work with clinicians and their pediatric asthma patients at the Dayton Children's Hospital to evaluate an IoT/mobileApp enabled personalized digital health management. We built a kHealth system for continuous monitoring and improved tracking of 30 parameters including the child’s symptoms, activities, sleep, and treatment adherence. It can allow precise determination of asthma triggers and a reliable assessment of medication compliance and effectiveness.

https://sites.google.com/view/deep-dial-2019/keynotes
Understanding and managing health is complex. Throughout the last few decades of modern medicine, we have relied clinicians on most health-related decision making. New technologies have enabled a growing involvement of patients in their own health management, aided by increasing variety and amount of patient-generated health data. Augmented personalized health [http://bit.ly/k-APH, http://bit.ly/APH-HI] strategy has outlined a broad variety of patient and clinician engagement in devising an increasingly more sophisticated and powerful health management solutions - from self-monitoring, self-appraisal, self-management, intervention to the prediction of disease progression and planning. Chatbot could play a pivotal role throughout the unfolding data-driven, AI-supported ecosystem [http://bit.ly/H-Chatbot] that engages patients and clinicians in collecting data, in driving their actions, informing them of their choices, and even delivering part of the clinical care (e.g., Cognitive Behavioral Therapy (CBT) for mental health patients). Nevertheless, this will require quite a few advances in making a more intelligent technology. In this talk, we will share some experience and observations based on our ongoing collaborative projects that usually involve clinicians and patients targeting pediatric asthma management, pre-and-post bariatric surgery care regimen, depression and other mental health issues, and nutrition. Using use cases and prototypes, we will elucidate the need, support, and use of domain- and user-specific knowledge graphs, Natural Language Processing (NLP), machine learning, and conversational AI for:
- multimodal interactions including text, voice, and other media, along with the use of diverse devices and software platforms for “natural” communication
- context enabled by deep relevant medical/healthcare knowledge including clinical protocols
- personalization by collecting and using the history of the individual patient from IoT health devices, open data, and Electronic Medical Record (EMR)
- abstraction by aggregating and correlating diverse streams data to draw plausible explanation(s) based on public (cohort-level) data (for example percentage of asthmatic patient who gets symptom when exposed to certain triggers) and personal data
- smart dialogue (intent) management and response generations by causal relations and inference of association

We are now living in the information society and global village of which we are bombarded with huge sums of information which is not all relevant to us. It is therefore imperative to be well equipped with information literacy skills so as to curb the information explosion. Simply being exposed to a great deal of information will not make people informed citizens, they need information literacy skills. Information literacy comes as a ‘medicine’ in curing the information exposition. Information seekers can tackle information explosion by employing strategies such as information literacy education, development of information search skills, library education, user orientation, bibliographic user instruction, information fluency and all other information literacy competencies.

Quantified Self Ideology: Personal Data becomes Big DataMelanie Swan
A key contemporary trend emerging in big data science is the quantified self: individuals engaged in the deliberate self-tracking of any kind of biological, physical, behavioral, or transactional information, as n=1 individuals or in groups. The quantified self is one dimension of the bigger trend to integrate and apply a variety of personal information streams including big health data (genome, transcriptome, environmentome, diseasome), quantified self data streams (biosensor, fitness, sleep, food, mood, heart rate, glucose tracking, etc.), traditional data streams (personal and family health history, prescription history) and IOT (Internet of things) activity data streams (smart home, smart car, environmental sensors, community data). This talk looks at how personal data and group data are becoming big data as individuals and communities share, collaborate, and work with large personalized data sets using novel discovery methods such as anomaly detection and exception reporting, longitudinal baseline analysis, episodic triggers, and hierarchical machine learning.

Understanding Online Socials Harm: Examples of Harassment and RadicalizationAmit Sheth
https://dbsec2019.cse.sc.edu/Keynote.html
Abstract: As social media permeates our daily life, there has been a sharp rise in the misuse of social media affecting our society in large. Specifically, harassment and radicalization have become two major problems on social media platforms with significant implications on the well-being of individuals as well as communities. A 2017 Pew Research survey on online harassment found that 66% of adult Internet users have observed online harassment and 41% have personally experienced it. Nearly 18% of Americans have faced severe forms of harassment online such as physical threats, harassment over a sustained period, sexual harassment or stalking. Moreover, malicious organizations (e.g., terrorist groups, white nationalists not classified legally as terrorists but as a group with extreme ideology) have been using social media for sharing their propaganda and misinformation to persuade individuals and eventually recruit them to propagate their ideology. These communications related to harassment and radicalization are complex concerning their language and contextual characteristics, making recognition of such narratives challenging for researchers as well as social media companies. As most of the existing approaches fail to capture fundamental nuances in the language of these communications, two prominent challenges have emerged: ambiguity and sparsity. Sole data level bottom-up analysis has been unsuccessful in revealing the actual meaning of the content. Considering the significant sensitivity of these problems and its implications at individual and community levels, a potential solution requires reliable algorithms for modeling such communications.
Our approach to understanding communications between source and target requires deciphering the unique language, semantic and contextual characteristics, including sentiment, emotion, and intention. This context-aware and knowledge-enhanced computational approach to the analysis of these narratives breaks down this long-running and complex process into contextual building blocks that acknowledge inherent ambiguity and sparsity. Based on prior empirical and qualitative research in social sciences, particularly cognitive psychology, and political science, we model this process using a combination of contextual dimensions -- e.g., for Islamist radicalization: religion, ideology, and hate -- each elucidating a degree of radicalization and highlighting independent features to render them computationally accessible.

In this talk, we present and discuss various research and development projects focused on addressing some of the societal challenges of today’s world (misinformation spreading, extremism, child grooming) by means of social data science. These problems are complex, dynamic and heterogeneous, and cannot be looked at from a single lens. We will discuss how these problems are addressed from a multidisciplinary angle, combining theories, models and methods from social science, computer science, or psychology; bringing a deeper understanding of the problems, and their relations to users and their behaviours, to the proposed solutions.

We will discuss how these problems are addressed from a multidisciplinary angle, combining theories, models and methods from social science, computer science, or psychology; bringing a deeper understanding of the problems, and their relations to users and their behaviours, to the proposed solutions.

Civic educators, social workers, curriculum developers, policy makers and parents concerned with the takeover of social media by hate speech proponents can apply these findings and help youth withstand manipulation and fight racism, hate speech, radicalization, and cyberbullying through the Get Ready to Act Against Social Media Propaganda model generated by this study. The model includes five iterative stages: Question, analyze, design, prepare and evaluate.
Can Artificial Intelligence Predict The Spread Of Online Hate Speech?Bernard Marr
Online hate speech is a big issue, and many are worried that it leads to radicalization and actions in the real world. Here, we look at how artificial intelligence (AI) can now be used to detect hate speech and predict its impact.

Improving Workplace Safety Performance in Malaysian SMEs: The Role of Safety ...AJHSSR Journal
ABSTRACT: In the Malaysian context, small and medium enterprises (SMEs) experience a significant
burden of workplace accidents. A consensus among scholars attributes a substantial portion of these incidents to
human factors, particularly unsafe behaviors. This study, conducted in Malaysia's northern region, specifically
targeted Safety and Health/Human Resource professionals within the manufacturing sector of SMEs. We
gathered a robust dataset comprising 107 responses through a meticulously designed self-administered
questionnaire. Employing advanced partial least squares-structural equation modeling (PLS-SEM) techniques
with SmartPLS 3.2.9, we rigorously analyzed the data to scrutinize the intricate relationship between safety
behavior and safety performance. The research findings unequivocally underscore the palpable and
consequential impact of safety behavior variables, namely safety compliance and safety participation, on
improving safety performance indicators such as accidents, injuries, and property damages. These results
strongly validate research hypotheses. Consequently, this study highlights the pivotal significance of cultivating
safety behavior among employees, particularly in resource-constrained SME settings, as an essential step toward
enhancing workplace safety performance.
KEYWORDS :Safety compliance, safety participation, safety performance, SME

individual or group, or is intended to be derogatory,
to humiliate, or to insult the membe
rs of the group, on the basis of attributes such as

Challenges in Online Harassment Detection
Ambiguity

that overlaps, causing ambiguity in annotations
“Profanity, strongly impolite, rude or vulgar language
expressed with fighting or hurtful words in order to
insult a targeted individual or group is offensive
language ” - Founta et al. 2018

14. ALONE: A Dataset for Toxic Behavior among Adolescents on Twitter
Unique characteristics of the ALONE dataset:
● Data of Adolescent population
● Data organized based on interactions
● Multimodal Data
● Further insights:
○ Positive and negative lexical items in tweets used with
contextual analysis of interactions suggest sarcasm and
sometimes exonerate the potential toxic content.
○ Toxic interactions contain significantly high number of tweets
per interaction along with a high number of multimodal
elements such as images, videos and emojis.

Knowledge-aware assessment of severity of suicide risk for early intervention.
In The Web Conference 2019
1. Estimating the severity of suicide risk of an individual without the use of Clinician-
authorized Questionnaire would hurt the explainability of the model.
2. Challenge in Social Media: (a) Dynamic user Roles and Behavior, (b) Sparsity in
Clinician-specific information, and (c) How to adapt Questionnaire to Social Media
3. The study addresses these questions in following ways:
a. Clinical knowledge to study user roles (supportive/non-supportive) and
behaviors (transitioning between communities on Reddit)
b. Columbia-Suicide Severity Rating Scale was modified and adapted to social
Media -- Two new classes were added {Supportive, Suicide Indication}
c. Contextualization and Abstraction procedures were developed for explainable
classification.

Knowledge-infused Abstractive Summarization of Clinical Diagnostic
Interviews In JMIR Mental Health 2021
1. How to pick the relevant question from the recorded script of interview?
2. How to associate the meaningful response to the question being asked?
3. While addressing the 1 and 2, how to incorporate domain knowledge?
4. Addressing 1,2, and 3, how to effectively summarize the long open-ended Clinical
Diagnostic Interviews.
The strategy for summarizing is heavily grounded in the use of mental health knowledge
crafted in prior literature: PHQ-9 Lexicon, DSM-5 Lexicon, Hierarchical knowledge in
SNOMED-CT, and Anxiety Lexicon.
In natural language processing, a domain-specific language model was designed
specific for CDIs and used to identify terms in CDIs which are important for summaries.

V: Consider a graphic at the outset for data driven and knowledge driven approaches, and your infused approach.
Same for ALONE dataset and online toxicity as well.
You need to provide a very strong argument as why they are not alone enough to capture context and knowledge.
Earlier, we have to state that why sole ML solutions and KG solutions have limitations. And why we need knowledge.

“In general, a single tweet identified as ‘harassing’ may not provoke the same intense negative feeling that we associate with that word in the real-world scenario. However, in practice, ‘conversational’ exchanges containing a sequence of such tweets can rise to the level of harassment causing mental and psychological anguish, and fear of physical harm.”
Ambiguity: Different meanings of diagnostic terms
Sparsity: Low prevalence of relevant content
Subjectivity: Different perceptions of same concepts.
Multi Dimensionality: Nature of content with more than one context.
Multimodal Content: Different modalities of data

Raw SQI does not take into account preceding state conditions.
Change in SQI is also potentially informative, particularly for comparisons between states.
We transformed raw state SQI into a relative state ranking, to capture drifts between worsening and improvement.
Used to examine the effect of events, e.g., school closure, business closure, unemployment, and lockdown on worsening mental health.

Much of these is due to meditation, yoga, indoor games, increase use of streaming video platforms
Among many external factors, financial events and the specific government interventions have substantial effect in the social quality of people. Specifically, business and individual relief announcements, business closures, increase in unemployment, and stay at home orders. Whenever the unemployment increase is much more significant than the previous week, the social quality is worse; and whereas whenever the individuals and businesses are given financial reliefs, the social quality is better.
