摘      要：Question Answering(QA),the process of computing valid answers to questions formulated in natural language,has recently gained attention in both industry and *** this idea to the realm of geographic information systems(GIS)may open new opportunities for data *** theory,analysts may simply ask spatial questions to exploit diverse geographic information resources,without a need to know how GIS tools and geodata sets *** this outlook article,we investigate the scientific challenges of geo-analytical question answering,introducing the problems of unknown answers and indirect ***,we argue why core concepts of spatial information play an important role in addressing this challenge,enabling us to describe analytic potentials,and to compose spatial questions and workflows for generating answers.
