2.3.3. Validation of AI-Based Newsfeed
To validate the newsfeed, a three-step process was employed. Initially, keywords were selected to generate lists of relevant articles, requiring consensus from four out of five study staff members on the articles’ relevance, their coverage of health facts, preventive strategies, and readability at an 8th-grade level. Articles meeting these criteria were utilized to train the AI algorithm over a 13-week period to enhance accuracy and precision. Before deployment, each newsfeed exceeded a 70% accuracy threshold, and further refinement was achieved by imposing more stringent parameters. Within this project, exclusionary terms such as COVID-19 were introduced. AI newsfeeds underwent 13 weeks of training, observing accuracy plateauing as depicted in
