    Als Yang vor einigen Tagen auf einer Konferenz die Neuentwicklungen für Mobiltelefone vorstellte, stand er lange alleine auf der Bühne. Seinen blassen Kompagnon Filo holte er erst am Ende kurz dazu. Yang, gewohnt leger im blauen Pulli mit V-Ausschnitt und beiger Hose, begann seinen Vortrag mit einem Scherz: "Sie wollen den neuen Look von Yahoo sehen, das neue Gesicht. Ich werde Sie enttäuschen müssen. Es ist immer noch das alte." Nämlich seines. Er ist der Mann fürs Rampenlicht, zumindest wenn es sein muss. Im vergangenen Jahr hat Yang im Konzern wieder die Leitung übernommen. Der vorherige Chef wechselte wegen der schwachen Börsenkurse in den Aufsichtsrat. Den Titel "Chief Yahoo!" hatte der gebürtige Taiwanese ohnehin nie abgelegt. Das Silicon Valley gehört zu seiner Erfolgsgeschichte wie sein Lebenslauf. Mit seiner Mutter und seinem Bruder kam er im Alter von zehn Jahren im kalifornischen San José an, der selbsternannten Hauptstadt des High-Tech-Tals, in dem die Start-up-Millionäre wohnen. Apple, Ebay, Google, alle haben in dieser Gegend angefangen. Als Yang nach San José kam, soll er nur ein englisches Wort gekannt haben: Shoes. Er lernte schnell andere Wörter dazu, in der Schule war er ein Mathe-Ass. Und obwohl Stanford erklärte, ihn finanziell nicht umfangreich mit Stipendien unterstützen zu können, beschloss er, genau dort, auf dem Campus im Silicon Valley, sein Studium zu beginnen. Während seiner Promotion legte er zusammen mit David Filo ein Netzverzeichnis an, das sie "Jerry's Guide to the World Wide Web" nannten. Schon da stand sein Name im Vordergrund. Die Büros der beiden waren klein und recht unordentlich, aber bei Yang lagen zwischen den Büchern und Zetteln immerhin keine T-Shirts und dreckigen Socken wie bei Filo. Wahrscheinlich haben all diese Anekdoten dem Image der beiden eher geholfen als geschadet, jedenfalls bekamen sie eine Million Dollar von einem Wagnis-Kapital-Geber. Als sie wenig später an die Börse gingen, stieg der Kurs am ersten Tag um 154 Prozent. Ihre kleine Firma war trotz der überschaubaren Umsätze plötzlich 800 Millionen Dollar wert. Yang ließ seine Promotion ruhen. Bis heute. Trotzdem ist er alles andere als ein lässiger Abhänger. Er war immer smart, strebsam und arbeitete, wenn es sein musste, Tag und Nacht. Damit erfüllte er in den Jahren des Internet-Booms jenes Klischee, das asiatischen Einwanderern nachgesagt wurde. Nur hatte das jetzt keinen negativen Touch mehr. "Sie sind so etwas wie die Helden der Jahrhundertwende", schrieb das Time Magazin über erfolgreiche asiatische Einwanderer. Ein Beispiel: Jerry Yang.

    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.

    Abstract
    »Googeln« ist längst als Verb für die Internet-Suche in den Sprachgebrauch eingegangen, aber auch das Unternehmen selbst findet sich seit der 23. Ausgabe des Dudens im offiziellen Sprachschatz der Deutschen. Der Namen der Suchmaschine stammt vom Wort Googol, einer Eins mit hundert Nullen. Googol wurde von Milton Sirotta, einem Neffen des USMathematikers Edward Kasner, geprägt. Der Name verdeutlicht symbolisch das Ziel, die enorme Menge an Informationen im Web und auf der ganzen Welt zu organisieren. Die Gründer von Google konnten lange Zeit von einem Sympathie-Bonus zehren, der ihnen als Jungunternehmer und Garagenfirma entgegengebracht wurde - aber auch ein technischer Vorsprung gegenüber den damaligen und heutigen Konkurrenten sorgten für den Aufstieg des Unternehmens in der Gunst der Nutzer. Die Bekanntheit der Suchmaschine wurde fast ausschließlich über Mund-zu-Mund-Propaganda erreicht. Wichtig waren dabei die neuartige PageRank-Technologie, mit der die Websites komplex bewertet werden sowie das schlichte Design der Suchmaschine. Google profitiert zudem bis heute vom Ruf eines High-Tech-Unternehmes. Google ist seit Herbst 2004 ein börsennotiertes Unternehmen (mit mehr als 3.000 Mitarbeitern und über 100.000 Servern) und kann wohl auch im jahr 2005 die Spitzenposition im Suchmaschinenmarkt behaup ten: Während im Dezember 2004 im US-amerikanischen Markt der Anteil bei rund 48 Prozent der vermittelten Suchanfragen lag (einschließlich AOL, Netscape und Excite), beträgt dieser Anteil in Deutschland über 80 Prozent (einschließlich AOL und T-Online). Google hat den Erfolg jedoch nicht gepachtet: Die Hauptkonkurrenten Yahoo! und MSN sind Google im US-amerikanischen Markt dicht auf den Fersen. Und möglicherweise zieht eines Tages ein anderes Unternehmen mit einer völlig revolutionären Suchtechnologie an Google vorbei. Deshalb wird viel für die Entwicklung der Technologie und die Kundenbindung getan. Dazu gehören Entwicklungen wie die Toolbar, Deskbar, Desktop-Suche und der E-Mail-Dienst Gmail.
