Information security is based on access control models and cryptographic techniques. These are well established areas of research in computer security, but are not capable of supp...
The search for relevant information is often hindered by the initial difficulty in formulating precise requests, and because much knowledge is actually tacit and thus not easily ac...
In this paper we start to explore two-part collocation extraction association measures that do not estimate expected probabilities on the basis of the independence assumption. We ...
Abstract. We have been witnessing an explosion of user involvement in knowledge creation, publication and access both from within and between organisations. This is partly due to t...
Comparing the expressive power of access control models is recognized as a fundamental problem in computer security. Such comparisons are generally based on simulations between di...
