    Abstract
    PageRank is defined as the stationary state of a Markov chain. The chain is obtained by perturbing the transition matrix induced by a web graph with a damping factor alpha that spreads uniformly part of the rank. The choice of alpha is eminently empirical, and in most cases the original suggestion alpha=0.85 by Brin and Page is still used. Recently, however, the behaviour of PageRank with respect to changes in alpha was discovered to be useful in link-spam detection. Moreover, an analytical justification of the value chosen for alpha is still missing. In this paper, we give the first mathematical analysis of PageRank when alpha changes. In particular, we show that, contrarily to popular belief, for real-world graphs values of alpha close to 1 do not give a more meaningful ranking. Then, we give closed-form formulae for PageRank derivatives of any order, and an extension of the Power Method that approximates them with convergence O(t**k*alpha**t) for the k-th derivative. Finally, we show a tight connection between iterated computation and analytical behaviour by proving that the k-th iteration of the Power Method gives exactly the PageRank value obtained using a Maclaurin polynomial of degree k. The latter result paves the way towards the application of analytical methods to the study of PageRank.

    Content
    "Nobody is perfect - diese Weisheit trifft auch auf Suchmaschinen zu. Google, Yahoo und Co. finden zwar viel, aber nicht alles. Insbesondere bei Spezialthemen ist es ratsam, eine Meta-Suchmaschine wie Metacrawler (www.metacrawler.de), MetaGer (meta.rrzn.uni-hannover.de) oder Ixquick (www.eu.ixquick.com) zu Rate zu ziehen. Sie fragen gleichzeitig mehrere Suchmaschinen ab. Bei Metacrawler sind dies beispielsweise 22 internationale und 15 nationale Suchdienste. Ixquick durchstöbert gleichzeitig mindestens zehn der populärsten Suchmaschinen und dies in 17 Sprachen. Dadurch verbessert sich die Trefferquote natürlich erheblich. Eine weitere gute Möglichkeit, die spezielle Suche im Internet spürbar zu erleichtern, ist die Benutzung eines Webkataloges. Zu empfehlen sind Excite (www.excite.de), das Suchlexikon (www.suchlexikon.de) oder auch das englischsprachige Angebot iTools (www.itools.com). Diese Webkataloge können als "Verzeichnisse von Suchmaschinen" bezeichnet werden. Sie bündeln verschiedene Suchmaschinen zu bestimmten Themengebieten wie Wirtschaft, Freizeit, Computer oder Sport. Keine Suchmaschine im eigentlichen Sinne, aber dennoch sehr nützlich, um an Informationen oder auch Ratschläge im Netz zu kommen, ist Wikipedia (de.wikipedia.org). Das Internet-Lexikon hat sich den Beinamen "die freie Enzyklopädie" gegeben und dient als Sammelpunkt für Informationen und Wissen der User. Dies ist allerdings auch die Schwäche der Seite, denn um eine hundertprozentig verlässliche Antwort zu bekommen, sind die Angaben oft zu ungenau. Eine interessante Variante ist die News-Suchmaschine Paperball (www.paperball.de). Hierbei werden die Online-Ausgaben deutscher und internationaler, Tagesund Wochenzeitungen durchforstet. Man kann die Suche auch auf bestimmte Rubriken beschränken. Auf der Suche nach ehemaligen Mitschülern? Dann sind Sie bei StayFriends (www.stayfriends.de) genau richtig. Nach einer kostenlosen Anmeldung kann man nach verloren gegangenen Freunden aus der Schulzeit fahnden. Fast 1,8 Millionen Einträge sollen laut Anbieter bereits auf der Seite eingegangen sein. Der Nachteil: Wer sich nicht eingetragen hat, wird auch nicht gefunden. Wer gezielt nach Bildern sucht, wird bei Bomis (www.bomis.com) fündig. Hierbei werden nur Seiten durchstöbert, auf denen sich Bilder zu bestimmten Themen oder Personen befinden. Abschließend sei allen Internetnutzern noch eine ganz spezielle Seite ans Herz gelegt. Die Suchfibel (www.suchfibel.de) gibt wichtige Tipps für das richtige Suchen im Netz. Zum einen werden hier Ratschläge gegeben, die das Finden von Informationen im Web einfacher machen, zum anderen listet die Seite auch 2700 verschiedene Suchmaschinen - nach Stichwörtern geordnet - auf."
