    Abstract
    Das GOS Thesaurus-Handbuch wurde für die Teilnehmer an dem von der ROBERTBOSCH-STIFTUNG geförderten Projekt "Sammlungsmanagement für kulturgeschichtliche Museen in den neuen Bundesländern" (Spitzname: "Knorr-Projekt") geschrieben. Es basiert auf den bereits Mitte der 80er Jahre vom Institut für Museumskunde in Zusammenarbeit mit dem heutigen Konrad-Zuse-Zentrum für Informationstechnik Berlin (ZIB) durchgeführten und 1988 publizierten Arbeiten im Projekt "Kleine Museen".' Schon damals war zu erkennen, daß die international gültige Thesaurusnorm auch in den Museen auf dem Siegeszug war. Heute ist sie die Grundlage aller wichtigen Projekte zur internationalen Zusammenarbeit bei der Museumsdokumentation. GOS-Benutzer, die sich noch nie mit solchen Dingen befaßt haben, können dieses Handbuch als eine allgemeine Einführung in die Thesaurusarbeit benutzen, denn es behandelt alle Grundfunktionen eines Thesaurus nach DIN 1463. Es besteht aus einem "Lesebuch", in dem es mehr um die Zusammenhänge und etwas Hintergrundwissen geht sowie einem "Datenkatalog" mit der Beschreibung der Datenfelder des Thesaurus, gedruckt aus einer kleinen GOS-Datenbank, aus der auch die "H i l f e t e x t e " im GOS-Menü geholt werden. Wir haben uns - mit einiger Mühe allerdings - jeden Hinweis auf "gerade in Entwicklung befindliche" und "in wenigen Monaten freizugebende" Leistungen von GOS verkniffen und uns auschließlich auf Dinge beschränkt, die in den am Projekt direkt beteiligten Museen vor März 1997 routinemäßig angewendet wurden.

    Abstract
    We determine analytically the modulus of the second eigenvalue for the web hyperlink matrix used by Google for computing PageRank. Specifically, we prove the following statement: "For any matrix A=(cP + (1-c)E)**T, where P is an nxn row-stochasticmatrix, E is a nonnegative nxn rank-one row-stochastic matrix, and 0<=c<=1, the second eigenvalue of A has modulus Betrag (Lambda_sub2)<=c. Furthermore, if P has at least two irreducible closed subsets, the second eigenvalue Lambda_sub2 = c." This statement has implications for the convergence rate of the standard PageRank algorithm as the web scales, for the stability of PageRank to perturbations to the link structure of the web, for the detection of Google spammers, and for the design of algorithms to speed up PageRank.

    Abstract
    Um aus diesen beiden unabhangigen Systemen zur Inhaltserschlieung ein einheitliches, multilinguales Recherchevokabular zu bilden wurden im Rahmen des CrissCross Projekts unidirektionale Verbindungen von den einzelnen Sachschlagwortern der SWD zu den (teilweise) synthetisierten Notationen der DDC gescha en. Mittels dieser Verbindungen soll ein praziser und umfassender Zugang zu DDC-erschlossenen Dokumenten uber SWD-Schlagworter gewahrleistet werden. Da DDC-Notationen aber eher ihre Entsprechung in einer Kombination aus Schlagwortfolge und Sachgruppe haben, kann dieses Mapping in der Regel nur von SWD in Richtung DDC ausgewertet werden ohne dass ein groerer Informationsverlust auftritt. Deshalb haben die erstellten Mappings immer eine spezielle Verknupfungsrichtung, bei der die SWD als Ausgangsvokabular und die DDC als Zielvokabular dient. Das Dokument startet in Abschnitt 2 mit einem Uberblick uber die vier verschiedenen CrissCross-Mappingrelationen. Diese Mappingrelationen sollen im Rahmen einer Erweiterung fur die SKOS-Spezi kation4 semantisch reprasentiert werden. SKOS soll dabei sowohl benutzt werden, um die Konzepthierarchien der SWD und der DDC darzustellen als auch um die Mappings zwischen den beiden zu reprasentieren. Anhand von zwei konkreten Beispielen wird in Abschnitt 3 genauer erklart, welche Probleme insbesondere bei der Abbildung der CrissCross-Mappingrelationen mit Hilfe der SKOSSpezi kation auftreten. Insbesondere die Unidirektionalitat der ursprunglichen CrissCross-Mappings ist problematisch, da die in SKOS de nierten Mappingrelationen von einer Bidirektionalitat ausgehen. Das heit die Mappings mussen sowohl nutzbar sein fur die Suche in SWD-erschlossenen Bestanden als auch fur die Suche in DDC-erschlossenen Bestanden. Anhand der Beispiele in Abschnitt 3 wird deshalb auch eine initiale Losungsidee entwickelt, wie die Unidirektionalitat der CrissCross-Mappings aufgehoben werden kann.
    Basierend auf der Analyse und der initialen Losungsidee aus Abschnitt 3 werden anschlieend in Abschnitt 4 konkrete Losungsvorschlage unterbreitet, wie die Losungsidee im Rahmen einer SKOS-Erweiterung umgesetzt werden kann. Es werden mehrere Losungsvorschlage vorgestellt und miteinander verglichen. Ein wichtiger Teil der Losungsvorschlage ist die Repräsentation von koordinierten Konzepten. Der andere wichtige Teil ist die Herleitung der CrissCross-Mappingrelationen von den existierenden, bidirektionalen SKOS-Mappingrelationen. Diese beiden Erweiterungen der SKOSSpezifikation konnen zusammen dazu genutzt werden, die Mappings im Rahmen des Semantic Webs einem groeren Zielpublikum zur Verfugung zu stellen und nutzbar zu machen.
