SHERLOCK: Semantic management of Location-Based Services in wireless environments

摘要

Location-Based Services (LBSs) are attracting great interest nowadays, mainly due to the economic value they can provide. So, different applications are being developed for tracking, navigation, advertising, etc., but most of those applications are designed for specific scenarios and goals with implicit knowledge about the application context. However, currently it is a challenge to provide a common framework that allows us to manage knowledge obtained from data sent by heterogeneous moving objects (textual data, multimedia data, sensor data, etc.). Moreover, the challenge is even greater considering situations where the system must adapt itself to contexts where the knowledge changes dynamically and in which moving objects can use different underlying wireless technologies and positioning systems.
