Semantically Enhanced Location-based Social Networks
Basma Hassan AlBanna;
Abstract
Trajectory data analysis has recently become an active research area.
This is due to the large availability of mobile tracking sensors, such as
GPS-enabled smart phones. However, those GPS trackers only provide
raw trajectories (x, y, t), ignoring information about the geographical locations,
transportation mode, etc. This information can contribute in
producing significant knowledge about movements, which transforms
raw trajectories into semantic trajectories. Therefore, research lately has
focused on semantic trajectories; their representation, construction, and
applications. Furthermore, advances in location acquisition and mobile
technologies also led to the addition of the location dimension to Social
Networks (SNs) and to the emergence of a newer class called Locationbased
Social Networks (LBSNs). One of the key applications of semantic
trajectories is location-based recommendation, which is a main function
of LBSNs.
This research investigates the current studies on semantic trajectories
so far. We propose a new classification schema for the research efforts in
semantic trajectory construction and applications. The proposed classification
schema includes three main classes: semantic trajectory modeling,
computation, and applications. Additionally we proposed a methodology
to semantically enhance LBSNs through extracting SN Geo-tagged
media annotations and using them as location semantics. This enabled
