Term-specific eigenvector-centrality in multi-relation networks

François Bry, Fabian Kneissl, Klara Weiand, Tim Furche
2012 International Journal of Social Network Mining  
Fuzzy matching and ranking are two information retrieval techniques widely used in web search. Their application to structured data, however, remains an open problem.  ...  This article investigates how eigenvector-centrality can be used for approximate matching in multirelation graphs, that is, graphs where connections of many dierent types may exist.  ...  Consequently, the approach presented in this article can accommodate rich graphs that represent, for example, both hypertext linking as well as semantic and social relationships.  ...

MARiO: Multi-Attribute Routing in Open Street Map [chapter]

Franz Graf, Hans-Peter Kriegel, Matthias Renz, Matthias Schubert
2011 Lecture Notes in Computer Science  
In recent years, the Open Street Map (OSM) project collected a large repository of spatial network data containing a rich variety of information about traffic lights, road types, points of interest etc  ...  Formally, this network can be described as a multi-attribute graph, i.e. a graph considering multiple attributes when describing the traversal of an edge.  ...  For example, we have information about traffic lights and altitudes connected to the nodes which have to be reassigned and post processed into edge attributes of a multi-attribute graph.  ...
