This model is an extension of the standard Vector Space model, which further takes into account the co-frequencies between the terms in a given reference corpus, that are considered to provide a distributional representation of the "semantics" of t...

This special issue on Ambient Semantic Computing (ASC) of the International Journal of Semantic Computing proposes a particular approach to the much debated new era of IT and computing, where computers leave the desktop and surround us everywhere. ASC is related to the terms Ubiquitous Computing, Pervasive Computing, and Ambient Intelligence – each of these terms is claimed by their protagonist...

As the technical infrastructure to support Grid environments matures, attention must be focused on integrating such technical infrastructure with technologies to support more dynamic access to services, and ensuring that such access is appropriately monitored and secured. Current approaches for securing organisations thorugh conventional firewalls are insufficient; access is either enabled or d...
