Combination of probabilistic and possibilistic language models
In a previous paper we proposed Web-based language models relying on the possibility theory. These models explicitly represent the possibility of word sequences. In this paper we ...

A Tree Switching Protocol for Multicast State Reduction
In this paper, we propose a new Tree Switching Protocol (TSP) to reduce multicast routing states required for a forest of multicast trees. The protocol accomplishes this goal by s...
