A variety of lossless compression schemes have been proposed to reduce the storage requirements of web graphs. One successful approach is virtual node compression [7], in which of...
In this work we propose a representation of the web as a directed hypergraph, instead of a graph, where links can connect not only pairs of pages, but also pairs of disjoint sets o...

Abstract--In the majority of studies on CSMA wireless networks, a contention graph is used to model the carrier sensing relationships among links. This is a 0-1 model in which two ...
Abstract. Graph matching is often used for image recognition. Different kinds of graph matchings have been proposed such as (sub)graph isomorphism or error-tolerant graph matching...
Abstract. Often graphs are used to investigate properties of logic programs. In general, different graphs represent different kinds of information of the corresponding programs. ...
