IAI employees come together once a month to present or to learn about innovations occurring across the company, while enjoying their lunch and other refreshments. At this month’s presentation, Principal Investigator Gang Mei discussed IAI’s Diversity rank-based Summarization Tool (DST). Developed under a research initiative for NAVAIR, DST helps intelligence analysts to assess perpetually changing content and trends by tracking the evolution of a target topic in real time. The text network is constructed and updated very efficiently to enhance real-time summary updating. The importance, diversity, and novelty of content in the summary are balanced and optimized through a principled graph-regularization framework. Mr. Mei discussed his group’s development of an advanced DivRank based paragraph ranking algorithm for article summarization under this work.
