Is there a public for natural language based search? This study, based on our experience with a Web portal, attempts to address criticisms on the lack of scalability and usability of natural language approaches to search. Our solution is based on InFact®, a natural language search engine that combines the speed of keyword search with the power of natural language processing. InFact performs clause level indexing, and offers a full spectrum of functionality that ranges from Boolean keyword operators to linguistic pattern matching in real time, which include recognition of syntactic roles, such as subject/object and semantic categories, such as people and places. A user of our search can navigate and retrieve information based on an understanding of actions, roles and relationships. In developing InFact, we ported the functionality of a deep text analysis platform to a modern search engine architecture. Our distributed indexing and search services are designed to scale to large document collections and large numbers of users. We tested the operational viability of InFact as a search platform by powering a live search on the Web. Site statistics and user logs demonstrate that a statistically significant segment of the user population is relying on natural language search functionality. Going forward, we will focus on promoting this functionality to an even greater percentage of users through a series of creative interfaces. © 2007 Springer-Verlag London Limited.
