Abstract

Social networking applications have become very important web services that provide Internet-based platforms for their users to interact with their friends. With the advances in the location-aware hardware and software technologies, location-based social networking applications have been proposed to provide services for their users, taking into account both the spatial and social aspects. Unfortunately, none of existing location-based social networking applications is a holistic system nor equips database management systems to support scalable location-based social networking services. In this paper, we present GeoSocialDB; a holistic system providing three location-based social networking services, namely, location-based news feed, location-based news ranking, and location-based recommendation. In GeoSocialDB, we aim to implement these services as query operators inside a database engine to optimize the query processing performance. Within the GeoSocialDB framework, we discuss research challenges and directions towards the realization of scalable and practical query processing for location-based social networking services. In general, we discuss the challenges in designing location- and/or rank-aware query operators, materializing query answers, supporting continuous query processing, and providing privacy-aware query processing for our three location-based social networking services.

走向基于位置的社交网络服务

社交网络应用程序已经成为非常重要的网络服务，它为用户提供了基于互联网的平台来与他们的朋友互动。随着位置感知硬件和软件技术的进步，基于位置的社交网络应用被提出为其用户提供服务，同时兼顾空间和社交两个方面。不幸的是，现有的基于位置的社交网络应用程序都不是一个完整的系统，也没有数据库管理系统来支持可扩展的基于位置的社交网络服务。在本文中，我们提出GeoSocialDB;一个完整的系统，提供三种基于位置的社交网络服务，即基于位置的新闻推送、基于位置的新闻排名和基于位置的推荐。在GeoSocialDB中，我们的目标是将这些服务作为数据库引擎中的查询操作符来实现，以优化查询处理性能。在GeoSocialDB框架内，我们讨论了实现基于位置的社交网络服务的可扩展和实用查询处理的研究挑战和方向。总的来说，我们讨论了在设计位置和/或排名感知查询操作符、实现查询答案、支持连续查询处理以及为我们的三个基于位置的社交网络服务提供隐私感知查询处理方面的挑战。
