Abstract: Information extraction systems often produce hundreds to thousands of strings on a specific topic. We present a method that facilitates better consumption of these strings, in an ex- ploratory setting in which a user wants to both get a broad overview of what's available, and a chance to dive deeper on some aspects. The sys- tem works by grouping similar items together, and arranging the remaining items into a hierar- chical navigable DAG structure. We apply the method to medical information extraction.
