This paper describes EagleEye, which is an intelligent system that provides business intelligence through advanced data mining and text analytics. Unlike traditional search engines, EagleEye is entity oriented, and an entity can be an organization, a person, or a place. Given an entity name, the basic function of EagleEye is to generate a consolidated view of the entity information it gathers from many disparate data sources and to organize and categorize it, and automatically detect entity relationships. EagleEye can also analyze the opinions of entities, evaluate whether they are positive or negative, and provide insight into many aspects of consumer sentiment toward product brands. This type of information can enable enterprises to manage the reputation of their brands and to respond more quickly to changes in the marketplace. We present the key technologiessuch as entity-name grouping, entity-relation extraction, and entity-oriented opinion miningthat were developed to support these functions. EagleEye has been successfully deployed to a number of clients across a variety of industries in China. Several case studies are presented to demonstrate in practice the capability and business value of EagleEye. © 2010 IBM.
