We present novel kernels based on structured and unstructured features for reranking the N-best hypotheses of conditional random fields (CRFs) applied to entity extraction. The fo...

In this paper we introduce a new notion of collective tree spanners. We say that a graph G = (V, E) admits a system of µ collective additive tree r-spanners if there is a system T...
: We study the minimum-cost bounded-skew routing tree problem under the Elmore delay model. We presenttwo approachesto construct bounded-skew routing trees: (i) the Boundary Mergin...

Abstract--This paper addresses multicast routing in circuitswitched multihop optical networks employing wavelength-division multiplexing. We consider a model in which multicast com...
This work presents a new multiobjective algorithm based on ant colonies, which is used in the construction of the multicast tree for data transmission in a computer network. The pr...
