Abstract

We investigated a topic-based navigation guidance system in the World Health Organization portal, compared the link connection network and the semantic connection network derived from the guidance system, analyzed the characteristics of the 2 networks from the perspective of the node centrality (in_closeness, out_closeness, betweenness, in_degree, and out_degree), and provided the suggestions to optimize and enhance the topic-based navigation guidance system. A mixed research method that combines the social network analysis method, clustering analysis method, and inferential analysis methods was used. The clustering analysis results of the link connection network were quite different from those of the semantic connection network. There were significant differences between the link connection network and the semantic network in terms of density and centrality. Inferential analysis results show that there were no strong correlations between the centrality of a node and its topic information characteristics. Suggestions for enhancing the navigation guidance system are discussed in detail. Future research directions, such as application of the same research method presented in this study to other similar public health portals, are also included.

Abstract

The Digital Public Library of America brings together the riches of America's libraries, archives, and museums, and makes them freely available to the world. In order to do this, DPLA has had to build elements of the national digital platform to connect to those institutions and to serve their digitized materials to audiences. In this article, we detail the construction of two critical elements of our work: the decentralized national network of "hubs," which operate in states across the country; and a version of the Hydra repository software that is tailored to the needs of our community. This technology and the organizations that make use of it serve as the foundation of the future of DPLA and other projects that seek to take advantage of the national digital platform.

Abstract

Im Jahr 2007 hat die GWLB gemeinsam mit der HAAB, der Universitätsbibliothek Johann Christian Senckenberg und mehreren Stiftungen die Königliche Gartenbibliothek Herrenhausen erworben. Neben den textuellen Materialien enthält die Bibliothek auch viele nicht-textuelle Materialien wie Herbarien, Zeichnungen und auch Gouachen mit Abbildungen von Obstsorten aus der ehemaligen Obstbaumplantage. Nachdem in einem ebenfalls hier abgedruckten Aufsatz technische und inhaltliche Aspekte, die bei der Planung und Durchführung von Digitalisierungsprojekten von nicht-textuellen Materialien zu beachten sind, erläutert wurden, sollen im Folgenden konkrete Beispiele unterschiedlicher Präsentationen digitaler Bildbestände besprochen werden. Das Canadian Heritage Information Network bietet als Grundlage für die Beurteilung von Bilddatenbanken eine 37 Seiten umfassende Word-Datei zu Abklärung aller möglichen Anforderungen (bspw. Inventarisierung, Ausleihe, verschiedene Suchoptionen, Urheberrecht, Langzeitarchivierung, Kostenrechnung für Druckaufträge usw.) an eine Bilddatenbank an . Diese Liste ist ursprünglich für den Museumsbereich zusammengestellt worden und darum für den Bibliotheksbereich nur teilweise übertragbar. Die folgenden Beispiele wurden daher nach eigenen Kriterien miteinander verglichen, um zu analysieren, welche Angebote bzw. Bestandteile dieser Angebote als Anregung für die Präsentation nicht-textueller Materialien wie den Gouachen der Königlichen Gartenbibliothek dienen könnten. Hierbei wurden die Punkte Erschließung, Sicherung, Digitalisierung, Metadaten und Präsentation betrachtet. Nach einer umfassenden Recherche wurden von der Fülle der unterschiedlichen Internetpräsentationen insgesamt 14 verschiedene Angebote ausgewählt. Zur Verbesserung der Übersichtlichkeit wurden die Datenbanken thematisch zusammengefasst (allgemeine Portale, pomologische und botanische Datenbanken, sowie andere Themenbereiche). Auf den folgenden Seiten werden einige der untersuchten Datenbanken kurz vorgestellt.
