TL;DR: In this paper, the authors advocate the adoption of novel access control policy models that follow two main design guidelines: context-awareness to control resource access on the basis of context visibility and to enable dynamic adaptation of policies depending on context changes, and semantic technologies for context/policy specification.

TL;DR: The socially aware and mobile architecture (SAMOA) integrates a set of common management facilities for personalizing location-dependent social networks, and for propagating social networks' visibility up to the application level.

TL;DR: A middleware-level approach to support user-centric semantic service discovery, called AIDAS, exploits context-awareness based on user/device/service profile metadata to provide personalized views on services of interest, and supports semantic-based matchmaking between requested and offered service capabilities.

TL;DR: A semantic-based secure discovery framework for mobile healthcare enterprise networks that exploits semantic metadata (profiles and policies) to allow flexible and secure service search/retrieval and integrates access control functionalities within the discovery framework to provide users with filtered views on available services based on service access requirements and user security credentials.

TL;DR: MIDAS middleware exemplifies how to exploit context awareness based on user/device/service profile metadata and semantic-based matchmaking to allow flexible matching between requirements and capabilities in open and dynamic deployment scenarios.
