A Framework of Web Data Integrated LBS Middleware

摘要

In this paper, we propose a flexible location-based service (LBS) middleware framework to make the development and deployment of new location based applications much easier. Considering the World Wide Web as a huge data source of location-relative information, we integrate the common used web data extraction techniques into the middleware framework, exposing a unified web data interface for the upper applications to make them more attractive. Besides, the framework also emphasizes some common LBS issues, including positioning, location modeling, location-dependent query processing, privacy and secure management.
