Abstract Chatbots hold the promise of revolutionizing education by engaging learners, personalizing learning activities, supporting educators, and developing deep insight into learners’ behavior. However, there is a lack studies that analyze recent evidence-based chatbot-learner interaction design techniques applied in education. This study presents systematic review 36 papers to understand, compare, reflect on attempts utilize chatbots using seven dimensions: educational field, platform, principles, role chatbots, styles, evidence, limitations. The results show were mainly designed web platform teach computer science, language, general education, few other fields such as engineering mathematics. Further, more than half used teaching agents, while third peer agents. Most predetermined conversational path, quarter utilized personalized approach catered students’ needs, experiential collaborative besides principles. Moreover, evaluated with experiments, primarily point improved subjective satisfaction. Challenges limitations include inadequate or insufficient dataset training reliance usability heuristics. Future should explore effect chatbot personality localization satisfaction effectiveness.

There has been an increasing interest in translating artificial intelligence (AI) research into clinically-validated applications to improve the performance, capacity, and efficacy of healthcare services. Despite substantial worldwide, very few AI-based have successfully made it clinics. Key barriers widespread adoption clinically validated AI include non-standardized medical records, limited availability curated datasets, stringent legal/ethical requirements preserve patients' privacy. Therefore, there is a pressing need improvise new data-sharing methods age that patient privacy while developing applications. In literature, significant attention devoted privacy-preserving techniques overcoming issues hampering actual clinical environment. To this end, study summarizes state-of-the-art approaches for preserving Prominent such as Federated Learning Hybrid Techniques are elaborated along with potential attacks, security challenges, future directions.

Consumer research on conversational agents (CAs) has been growing. To illustrate and map out in this field, we conducted a systematic literature review (SLR) of published work indexed the Clarivate Web Science Elsevier Scopus databases. Four dominant topical areas were identified through bibliographic coupling. They are 1) consumers’ trust CAs; 2) Natural Language Processing (NLP) developing designing 3) communication with 4) impact CAs value creation for business. We leverage these findings to provide an updated synopsis extant scientific work.

We screened articles based on their abstracts keywords text, reviewed potentially relevant articles, references to (a) assess whether article met inclusion criteria (b) additional articles. Chatbots, cases, design characteristics were extracted from information other sources by accessing those chatbots that publicly accessible.Our returned 3334 61 our criteria, 30 countries identified. categorized case(s) design. Six categories emerged comprising 15 distinct cases: risk assessment, dissemination, surveillance, post-Covid eligibility screening, distributed coordination, vaccine scheduler. Design-wise, relatively simple, implemented using decision-tree structures predetermined options, focused narrow set simple tasks, presumably due need quick deployment.Chatbots' scalability, wide accessibility, ease use, fast dissemination provide complementary functionality augments workers activities, addressing capacity constraints, social distancing requirements, misinformation.
