Workshop Keynote Speaker Information Surgeon
Heng Ji, University of Illinois at Urbana Champaign, USA
During crazy times like pandemic, the information released from multiple sources is not only overwhelming in terms of amount, but also misleading in terms of quality. For example, the U.S. Army reservist Maatje Bensassi was falsely accused as the covid-19 coronavirus pandemic's so-called "patient zero", without any evidence. Information pollution often has real-life consequences. Like many others, I had to unfriend or be unfriended by many people due to arguments about the source of coronavirus. Since we cannot fix human's brain, I propose new methods to fix information, namely not only to filter out misinformation/disinformation, but also correct it and generate a correct narrative. Understanding events and communicating about events are fundamental human activities. However, it's much more difficult to remember event-related information compared to entity-related information. For example, most people in the United States will be able to answer the question "Which city is Columbia University is located in?", but very few people can give a complete answer to "Who died from COVID-19?". Human-written history books are often incomplete and highly biased because "History is written by the victors". In this talk I will present a new research direction on event-centric knowledge base construction from multimedia multilingual sources, and then perform consistency checking and reasoning, and then describe the correct information. Our minds represent events at various levels of granularity and abstraction, which allows us to quickly access and reason about old and new scenarios. Progress in natural language understanding and computer vision has helped automate some parts of event understanding but the current, first-generation, automated event understanding is overly simplistic since it is local, sequential and flat. Real events are hierarchical and probabilistic. Understanding them requires knowledge in the form of a repository of abstracted event schemas (complex event templates), understanding the progress of time, using background knowledge, and performing global inference. Our approach to second-generation event understanding builds on an incidental supervision approach to inducing an event schema repository that is probabilistic, hierarchically organized and semantically coherent. Low level primitive components of event schemas are abundant, and can be part of multiple, sparsely occurring, higher-level schemas. Consequently, we combine bottom-up data driven approaches across multiple modalities with top-down consolidation of information extracted from a smaller number of encyclopedic resources. This facilitates inducing higher-level event representations analysts can interact with, and allow them to guide further reasoning and extract events by constructing a novel structured cross-media common semantic space. When complex events unfold in an emergent and dynamic manner, the multimedia multilingual digital data from traditional news media and social media often convey conflicting information. To understand the many facets of such complex, dynamic situations, we have developed various novel methods to induce hierarchical narrative graph schemas and apply them to enhance end-to-end joint neural Information Extraction, event coreference resolution, event time prediction, and knowledge base to natural language generation.
