In this paper, we address one of the central problems in text generation: the missing link ("the generation gap" in Meteer's terms) between the global discourse organization as often provided by text planning modules and the linguistic realization of this organization. We argue that the link should be established by the lexical choice proces s using resources derived from Mel'~uk's Lezical Func...

Immunization plays an important role in the field of epidemic spreading in complex networks. In previous studies, targeted immunization has been proved to be an effective strategy. However, when extended to networks with community structure, it is unknown whether the superior strategy is to vaccinate the nodes who have the most connections in the entire network (global strategy), or those in th...

In this paper, we propose an approach of object part contour features combination associated with global spatial structure for object detection. The object part contour is described using object contour direction histogram method to model thevariant characters in different shape. Since the edge points are related to the shape information closely, the local shape can often be characterized rathe...
