Context sensitive and time resolved relevance of Wikipedia articles — •Eric Tessenow¹, Mirko Kämpf², and Jan W. Kantelhardt² — ¹Institute for Communications Studies, University of Leeds, UK — ²Institut für Physik, Martin-Luther-Universität Halle-Wittenberg

Since the numbers of hypertext pages and hyperlinks in the WWW have been continuously growing for more than 20 years, the problem of finding relevant content has become increasingly important. We have developed and evaluated techniques for a time-dependent characterization of the global and local relevance of WWW pages based on document length, number of links, and cross-correlations in user-access time series. We focus on content and user activity in selected groups of Wikipedia articles as a first application mainly because of data availability. Our goal is the assignment of a ranking value to a hypertext page (node), which covers static properties of the given node and its neighborhood (context) as well as dynamic properties derived from their page-view rates. We show in several examples how this goal can be achieved.
