A complete bipartite set B is a subset of vertices admitting a bipartition B=X[union or logical sum]Y, such that both X and Y are independent sets, and all vertices of X are adjacent to those of Y. If both X,Y[not equal to][empty set], then B is called proper. A biclique is a maximal proper complete bipartite set of a graph. We present an algorithm that generates all bicliques of a graph in lexicographic order, with polynomial-time delay between the output of two successive bicliques. We also show that there is no polynomial-time delay algorithm for generating all bicliques in reverse lexicographic order, unless P=NP. The methods are based on those by Johnson, Papadimitriou and Yannakakis, in the solution of these two problems for independent sets, instead of bicliques. %Z %U http://www.sciencedirect.com/science/article/B6V1G-4FD0HTT-3/2/7efa1ee4d7b4823c7315a58b94f2f280 %+ %^ %0 %0 Journal Article %A Fiedler, M. %D 1975 %T A property of eigenvectors of nonnegative symmetric matrices and its application to graph theory %E %B Czechoslovak Mathematical Journal %C %I %V 25 %6 %N 100 %P 619--633 %& %Y %S %7 %8 %9 %? %! %Z %@ %( %) %* %L %M %1 %2 %3 article %4 %# %$ %F fiedler1975pen %K graph, spectral, theory %X %Z %U %+ %^ %0 %0 Journal Article %A Haveliwala, T.H. & Kamvar, S.D. %D 2003 %T The second eigenvalue of the Google matrix %E %B A Stanford University Technical Report http://dbpubs. stanford. edu %C %I %V %6 %N %P %& %Y %S %7 %8 %9 %? %! %Z %@ %( %) %* %L %M %1 %2 %3 article %4 %# %$ %F haveliwala8090seg %K graph, pagerank, spectral, theory %X %Z %U %+ %^ %0 %0 Conference Proceedings %A Dhillon, Inderjit S. %D 2001 %T Co-clustering documents and words using bipartite spectral graph partitioning %E %B KDD '01: Proceedings of the seventh ACM SIGKDD international conference on Knowledge discovery and data mining %C New York, NY, USA %I ACM Press %V %6 %N %P 269--274 %& %Y %S %7 %8 %9 %? %! %Z %@ 158113391X %( %) %* %L %M %1 %2 %3 inproceedings %4 %# %$ %F coclustering01 %K community, detection, graph, spectral, theory %X %Z %U http://portal.acm.org/citation.cfm?id=502512.502550 %+ %^ %0 %0 Manuscript %A Blelloch, Guy %D 2002 %T Graph Separators %E %B %C %I %V %6 %N %P %& %Y %S %7 %8 %9 %? %! %Z %@ %( %) %* %L %M %1 %2 %3 unpublished %4 %# %$ %F graphseparators02 %K graph, separators, theory %X %Z %U %+ %^ %0 %0 Journal Article %A Pothen, A.; Simon, H.D. & Liou, K.P. %D 1990 %T Partitioning Sparse Matrices with Eigenvectors of Graphs %E %B SIAM J.

In such a system, it is necessary to obtain provide brief semantic descriptions of peers, so that routing algorithms or matchmaking processes can make decisions about which communities peers should belong to, or to which peers a given query should be forwarded. This paper provides a graph clustering technique on knowledge bases for that purpose. Using this clustering, we can show that our strategy requires up to 58% fewer queries than the baselines to yield full recall in a bibliographic P2PKM scenario. %Z %U http://www.kde.cs.uni-kassel.de/stumme/papers/2006/schmitz2006content.pdf %+ %^ %0 %0 Book Section %A Brandes, Ulrik; Delling, Daniel; Gaertler, Marco; Görke, Robert; Hoefer, Martin; Nikoloski, Zoran & Wagner, Dorothea %D 2007 %T On Finding Graph Clusterings with Maximum Modularity %E Brandstädt, Andreas; Kratsch, Dieter & Müller, Haiko %B Graph-Theoretic Concepts in Computer Science %C Berlin / Heidelberg %I Springer %V 4769 %6 %N %P 121-132 %& %Y %S Lecture Notes in Computer Science %7 %8 %9 %? %! %Z %@ 978-3-540-74838-0 %( %) %* %L %M %1 %2 Abstract - SpringerLink %3 incollection %4 %# %$ %F springerlink:10.1007/978-3-540-74839-7_12 %K clustering, graph, modularity, theory %X Modularity is a recently introduced quality measure for graph clusterings. It has immediately received considerable attention in several disciplines, and in particular in the complex systems literature, although its properties are not well understood. We study the problem of finding clusterings with maximum modularity, thus providing theoretical foundations for past and present work based on this measure. More precisely, we prove the conjectured hardness of maximizing modularity both in the general case and with the restriction to cuts, and give an Integer Linear Programming formulation. This is complemented by first insights into the behavior and performance of the commonly applied greedy agglomaration approach. %Z %U http://dx.doi.org/10.1007/978-3-540-74839-7_12 %+ %^ %0 %0 Book %A Diestel, Reinhard %D 2005 %T Graph Theory %E %B %C %I Springer-Verlag Heidelberg, New York %V %6 %N %P %& %Y %S %7 3 (electronic edition) %8 %9 %? %! %Z %@ %( %) %* %L %M %1 %2 %3 book %4 %# %$ %F diestel2006graphentheorie %K book, density, diesel, graph, theory %X %Z %U http://www.math.ubc.ca/~solymosi/2007/443/GraphTheoryIII.pdf %+ %^
