Abstract

This highly practical handbook teaches you how to unlock the value of your existing metadata through cleaning, reconciliation, enrichment and linking and how to streamline the process of new metadata creation. Libraries, archives and museums are facing up to the challenge of providing access to fast growing collections whilst managing cuts to budgets. Key to this is the creation, linking and publishing of good quality metadata as Linked Data that will allow their collections to be discovered, accessed and disseminated in a sustainable manner. This highly practical handbook teaches you how to unlock the value of your existing metadata through cleaning, reconciliation, enrichment and linking and how to streamline the process of new metadata creation. Metadata experts Seth van Hooland and Ruben Verborgh introduce the key concepts of metadata standards and Linked Data and how they can be practically applied to existing metadata, giving readers the tools and understanding to achieve maximum results with limited resources. Readers will learn how to critically assess and use (semi-)automated methods of managing metadata through hands-on exercises within the book and on the accompanying website. Each chapter is built around a case study from institutions around the world, demonstrating how freely available tools are being successfully used in different metadata contexts. This handbook delivers the necessary conceptual and practical understanding to empower practitioners to make the right decisions when making their organisations resources accessible on the Web. Key topics include, the value of metadata; metadata creation - architecture, data models and standards; metadata cleaning; metadata reconciliation; metadata enrichment through Linked Data and named-entity recognition; importing and exporting metadata; ensuring a sustainable publishing model. This will be an invaluable guide for metadata practitioners and researchers within all cultural heritage contexts, from library cataloguers and archivists to museum curatorial staff. It will also be of interest to students and academics within information science and digital humanities fields. IT managers with responsibility for information systems, as well as strategy heads and budget holders, at cultural heritage organisations, will find this a valuable decision-making aid.

Abstract

MES (Manufacturing Execution Systems) sind zwischen der Automatisierungs- und der Unternehmensleitebene von Änderungen in der Produktion betroffen. Darum ist ihre Adaptivität im Lebenszyklus der Produktionsanlagen erfolgskritisch. Zusätzlich agieren MES als Daten- und Informationsdrehscheibe. Daher müssen sie möglichst gut und nahtlos mit anderen Systemen zusammenarbeiten: MES müssen interoperabel werden und dabei die Semantik im Griff haben. Die vorliegende Arbeit begegnet beiden Aspekten.

Abstract

In dieser Arbeit werden zwei Mehrwertdienste für Suchsysteme vorgestellt, die typische Probleme bei der Recherche nach wissenschaftlicher Literatur behandeln können. Die beiden Mehrwertdienste semantische Heterogenitätsbehandlung am Beispiel Crosskonkordanzen und Re-Ranking auf Basis von Bradfordizing, die in unterschiedlichen Phasen der Suche zum Einsatz kommen, werden in diesem Buch ausführlich beschrieben und evaluiert. Für die Tests wurden Fragestellungen und Daten aus zwei Evaluationsprojekten (CLEF und KoMoHe) verwendet. Die intellektuell bewerteten Dokumente stammen aus insgesamt sieben Fachdatenbanken der Fächer Sozialwissenschaften, Politikwissenschaft, Wirtschaftswissenschaften, Psychologie und Medizin. Die Ergebnisse dieser Arbeit sind in das GESIS-Projekt IRM eingeflossen.

Abstract

Mit der Einführung von EAI im eigenen Unternehmen verbinden die meisten Unternehmer positive Ergebnisse und Wirkungen beim Betrieb ihrer IT-Systeme. Die Koexistenz vieler verschiedener Anwendungssysteme, Betriebssysteme und/oder Hardware spielt nur noch eine untergeordnete Rolle. Die Lauffähigkeit der Geschäftsprozesse wird durch EAI gewährleistet, und das nicht nur unternehmensintern, sondern auch -extern. Vergleichbar mit einem Plug & Play wird den Unternehmen suggeriert, dass eine EAI einfach und schnell eine homogene Umgebung wenn auch virtuell - erzeugt.
