Web science: an interdisciplinary approach to understanding the web
The Web must be studied as an entity in its own right to ensure it keeps flourishing and prevent unanticipated social effects.
Creating a Science of the Web
Understanding and fostering the growth of the World Wide Web, both in engineering and societal terms, will require the development of a new interdisciplinary field.

Using Semantic Web Technologies for Policy Management on the Web
TLDR
Rein, a policy framework grounded in Semantic Web technologies, is proposed, which leverages the distributed nature and linkability of the Web to provide Web-based policy management and provides an engine for reasoning over these descriptions, both of which can be used to develop domain and policy language specific security systems.
