History repeats itself, sometimes in a bad way. If we don’t learn lessons from history, we might suffer similar tragedies, which are often preventable. For example, many experts now agree that some schools were closed for too long during COVID-19 and that abruptly removing millions of children from American classrooms has had harmful effects on their emotional and intellectual health. Also many wish we had invested in vaccines earlier, prepared more personal protective equipment and medical facilities, provided online consultation services for people who suffered from anxiety and depression, and created better online education platforms for students. Similarly, genocides throughout history (from those in World War II to the recent one in Rwanda in 1994) have also all shared early warning signs (e.g., organization of hate groups, militias, and armies and polarization of the population) forming patterns that follow discernible progressions. Preventing natural or man-made disasters requires being aware of these patterns and taking pre-emptive action to address and reduce them, or ideally, eliminate them. Emerging events, such as the COVID pandemic and the Ukraine Crisis, require a time-sensitive comprehensive understanding of the situation to allow for appropriate decision-making and effective action response. Automated generation of situation reports can significantly reduce the time, effort, and cost for domain experts when preparing their official human-curated reports. However, AI research toward this goal has been very limited, and no successful trials have yet been conducted to automate such report generation and “what-if” disaster forecasting. Pre-existing natural language processing and information retrieval techniques are insufficient to identify, locate, and summarize important information, and lack detailed, structured, and strategic awareness. We propose SmartBook, a novel framework that cannot be solved by ChatGPT, targeting situation report generation which consumes large volumes of news data to produce a structured situation report with multiple hypotheses (claims) summarized and grounded with rich links to factual evidence by claim detection, fact checking, misinformation detection and factual error correction. Furthermore, SmartBook can also serve as a novel news event simulator, or an intelligent prophetess. Given “What-if” conditions and dimensions elicited from a domain expert user concerning a disaster scenario, SmartBook will induce schemas from historical events, and automatically generate a complex event graph along with a timeline of news articles that describe new simulated events based on a new Λ-shaped attention mask that can generate text with infinite length. By effectively simulating disaster scenarios in both event graph and natural language format, we expect SmartBook will greatly assist humanitarian workers and policymakers to exercise reality checks (what would the next disaster look like under these given conditions?), and thus better prevent and respond to future disasters.
