This $546,000 National Science Foundation (NSF) Computer and Information Science and Engineering (CFDA 47.070) Project Grant award to The Pennsylvania State University, doing business as Penn State, supports research and development to advance trustworthy and human-centered summarization using large language models. The project aims to establish algorithmic foundations, technical innovations, public benchmarks, and integrated platforms for generating summaries that are customizable to user preferences, fair and unbiased across social groups, and aligned with human knowledge. Key research thrusts include incorporating fine-grained user preferences, embracing diverse social perspectives, and honoring human knowledge through multimodal summarization. The 5-year project, launching in September 2024, will deliver advancements in usable, trustworthy, and responsible artificial intelligence for efficient information gathering and knowledge acquisition.
