Indexing Structures for Geographic Web Retrieval
Luciana Teles Teixeira Andrade, M. J. Silva · 2006
Abstract. Context-aware search in mobile web environments demands new retrieval methods that rank web resources based on the proximity to users ’ locations. This paper presents the indexing and ranking architecture of a new geographic web retrieval system that can accept the user location as input and ranks searched items based on the estimated distances between the users and the resources. We describe the criteria to be considered by a geographic similarity metric and the indexing data structures that we created for fast selection of web resouces based on proximity. 1
