- Search engines currently struggle with queries where recall is more important than precision, such as exploratory search questions where the user wants to find all relevant information. - Endeca develops software to help users explore and understand complex information through an approach called "guided summarization" which aims to improve communication between the user and system. - Guided summarization presents search results to users in contextual summaries and offers options for refinement, aiming to cheat the typical recall vs. precision trade-off by facilitating an interactive dialog between the user and data.
