Comparing the hierarchy of keywords in on-line news portals
Gergely Tibély, David Sousa-Rodrigues, Péter Pollner +1
The tagging of on-line content with informative keywords is a widespread phenomenon from scientific article repositories through blogs to on-line news portals. In most of the cases…
Comparing the hierarchy of author given tags and repository given tags in a large document archive
Gergely Tibély, Péter Pollner, Gergely Palla
Folksonomies - large databases arising from collaborative tagging of items by independent users - are becoming an increasingly important way of categorizing information. In these s…
Hierarchical networks of scientific journals
Gergely Palla, Gergely Tibély, Enys Mones +2
Scientific journals are the repositories of the gradually accumulating knowledge of mankind about the world surrounding us. Just as our knowledge is organised into classes ranging…
Extracting tag hierarchies
Gergely Tibély, Péter Pollner, Tamás Vicsek +1
Tagging items with descriptive annotations or keywords is a very natural way to compress and highlight information about the properties of the given entity. Over the years several…
Ontologies and tag-statistics
Gergely Tibely, Peter Pollner, Tamas Vicsek +1
Due to the increasing popularity of collaborative tagging systems, the research on tagged networks, hypergraphs, ontologies, folksonomies and other related concepts is becoming an…
Criterions for locally dense subgraphs
Gergely Tibély
Community detection is one of the most investigated problems in the field of complex networks. Although several methods were proposed, there is still no precise definition of commu…
Communities and beyond: mesoscopic analysis of a large social network with complementary methods
Gergely Tibely, Lauri Kovanen, Marton Karsai +3
Community detection methods have so far been tested mostly on small empirical networks and on synthetic benchmarks. Much less is known about their performance on large real-world n…
Note on the equivalence of the label propagation method of community detection and a Potts model approach
Gergely Tibely, Janos Kertesz
We show that the recently introduced label propagation method for detecting communities in complex networks is equivalent to find the local minima of a simple Potts model. Applying…
Spectral methods and cluster structure in correlation-based networks
Tapio Heimo, Gergely Tibely, Jari Saramaki +2
We investigate how in complex systems the eigenpairs of the matrices derived from the correlations of multichannel observations reflect the cluster structure of the underlying netw…
Spectrum, Intensity and Coherence in Weighted Networks of a Financial Market
G. Tibely, J. -P. Onnela, J. Saramaki +2
We construct a correlation matrix based financial network for a set of New York Stock Exchange (NYSE) traded stocks with stocks corresponding to nodes and the links between them ad…
The effect of disorder on the hierarchical modularity in complex systems
David Nagy, Gergely Tibely, Janos Kertesz
We consider a system hierarchically modular, if besides its hierarchical structure it shows a sequence of scale separations from the point of view of some functionality or property…
