An ever-increasing number of today's mobile applications take advantage of location-based services (LBS) in order to proactively notify mobile users about location-dependent content or to execute location-dependent actions once the user enters or leaves a dedicated zone. The proactive LBS are thereby responsible to track the user's position energy-efficiently in the background and to continuously...
The penetration of smartphones and advancement of the location-based services have jointly contributed to the popularity of location-based social networking platforms such as Foursquare and Yelp. Business owners are important stakeholders of such location-based social network (LBSN) platforms, for whom setting up new businesses at the right location has immense importance in making a business popular...
In this paper, user log data of mobile notificationsare collected from a real mobile news application, and notificationopening rate and reaction time are identified as key parametersthat characterize user behavior. The results indicate that notificationopening patterns depend on the content of notifications, the time at which they are sent, the activeness of users, andthe reaction time. This paper...
The advent of the Internet of Things (IoT), with modern sensors and sensor-based devices, will significantly stimulate the development of context-aware applications. An effective means to extract higher-level contextual information from sensor data is distributed complex event processing (CEP), which facilitates the analysis of real-time data streams coming from heterogeneous and distributed sources...
Popularization of mobile devices promotes the development of E-commerce in which users produce plenty of implicit feedbacks (e.g., click, adding to wish list, purchase). Generally, the implicit feedback can be divided into the certain implicit feedback like purchase and the uncertain implicit feedback like click. However, certain implicit feedback is sparse while uncertain implicit feedback like click...
The prevalence of GPS devices has facilitated collection of large-scale trajectories. Fresh positions of moving objects can be sampled periodically and sent to servers for data analytics and query processing. Online trajectory simplification is a compression task usually conducted at the sensor side and serves as a key component to reduce network communication overhead. In this paper, we study a new...
Nowadays, Radio Frequency Identification (RFID) technology has been widely employed in the fields of object positioning, tracking and monitoring. However, there are a large number of redundant data generated in RFID systems due to duplicate detection and cross detection. Since RFID data is usually streaming, uncertain and mobile data, traditional static data and data stream filtering strategies cannot...
Spatial keyword querying has attracted considerable research efforts in the past few years. A prototypical query takes a location and keywords as arguments and returns the k objects that score the highest according to a ranking function. While different scoring functions have been used, how to compare different ranking functions for spatial keyword querying still remains an open question with little...
