Location based services: ongoing evolution and research agenda

TLDR
This article presents a series of key research challenges that are essential to advance the development of LBS, setting a research agenda for LBS to ‘positively’ shape the future of the authors' mobile information society.
Abstract
We are now living in a mobile information era, which is fundamentally changing science and society. Location Based Services (LBS), which deliver information depending on the location of the (mobile...

A survey of context modelling and reasoning techniques

TL;DR: The requirements that context modelling and reasoning techniques should meet are discussed, including the modelling of a variety ofcontext information types and their relationships, of situations as abstractions of context information facts, of histories of contextInformation, and of uncertainty of context Information.
