dc.description.abstractGeographic information retrieval (GIR) research mainly focuses on finding relevant geographic artifacts along one layer, although answers to queries should preferably include artifacts across multiple layers.This paper addresses this limitation, by exploiting relationships that exist between geographical objects of the same or different types. Given the existence of these relationships we can infer additional indirect semantic relationships between geographical objects that otherwise would be ignored. This semantic information contains multiple dimensions. This research creates a mathematical model of semantically relevant geographic objects that belong to different layers using the construct of multiplex networks. The proposed model respects and extends the “layered” structure of geographic data, and enhances the results of queries made to a GIS. A prototype system has been implemented over an existing GIS relational database. Experiments with the prototype show significant improvements in the results of queries, measured using precision and recall.en_US
