Distributed ranking methods for geographic information retrieval

Abstract

Geographic Information Retrieval is concerned with retrieving documents that are related to some location. This paper addresses the ranking of documents by both textual relevance and spatial relevance. To this end, we introduce distributed ranking, where similar documents are ranked spreaded in the list instead of sequentially. The effect of this is that documents close together in the ranked list have less redundant information. We present various ranking methods and efficient algorithms for them.
