Reviewing literature is painful albeit intellectually rewarding. I will describe SUNFLOWER, a system we developed in collaboration with Bloomsbury, a publisher of scienti?c material, member of Qatar Foundation. SUNFLOWER combines the power of search and collaborative editing to review and summarize a large number of articles around a topic. It works in three steps. The ?rst step performs a composite retrieval of related articles where k bundles of complementary articles are built using article metadata such as authors and citations. The second step associates a summary to each bundle by extracting key phrases from their constituent articles. The last step involves humans that collaboratively edit extracted summaries into a coherent literature review on the topic. We report our experiments on scienti?c articles from qscience.com
