Library Carpentry ist eine globale Community, die Software- und Datenkenntnisse an Menschen im Bibliotheksbereich vermittelt. Zum Tagesgesch{\"a}ft der Bibliothekar*innen im Metadatenmanagement geh{\"o}rt unter anderem die Aufbereitung von Rohdaten, das Zusammenf{\"u}hren von Daten aus unterschiedlichen Quellen, sowie die Umstrukturierung von Form und Inhalt. Oft enthalten die Rohdaten f{\"u}hrende Leerzeichen, falsche Zeichenkodierungen, verschiedene Datumsformate, Dubletten, nicht standardisierte Schreibweisen von Namen und weitere Inkonsistenzen. Um solche fehlerhaften Daten erkennen und korrigieren zu k{\"o}nnen, wird oft auf mehrere Werkzeuge zur{\"u}ckgegriffen. Ein echtes Multifunktionstool f{\"u}r diese Aufgabe ist "OpenRefine".In diesem Hands-On Lab wird "OpenRefine" vorgestellt und zur Transformation und Bereinigung von Daten eingesetzt. Die Teilnehmenden bearbeiten eine beispielhafte bibliothekarische Datei (Auszug aus dem DOAJ) mit "OpenRefine" und lernen die Kernfunktionalit{\"a}ten mit interaktiven {\"U}bungseinheiten kennen. Damit bietet dieses Hands-On Lab einen Einstieg in das Werkzeug "OpenRefine" und soll die Teilnehmenden zum praktischen Einsatz der Software in ihrer t{\"a}glichen Arbeit motivieren.Ein erster {\"U}berblick der Kursinhalte kann unter https://librarycarpentry.org/lc-open-refine/ eingesehen werden. Mitzubringen ist ein eigener Laptop. Bitte installieren Sie vor dem Hands-On Lab die Software OpenRefine auf Ihrem Laptop. Installationsanweisungen finden Sie auf der Library Carpentry Webseite: https://librarycarpentry.org/lc-open-refine/setup.html.

NFDI4Energy, part of the National Research Data Infrastructure (NFDI) initiative in Germany, aims to enhance data management and accessibility in energy research, advancing open science principles. However, the current extent of openness within energy research remains insufficiently explored. This study addresses two pivotal questions: To what extent do researchers in the energy domain follow open access publishing and data sharing practices? What trends and challenges emerge within the field of energy research? A bibliometric analysis was conducted using OpenAlex, an open metadata platform for scholarly outputs, to assess patterns of open access publications, data-sharing mentions, and collaboration networks in energy research. The preliminary findings indicate that openness in energy research exhibits variability across different subfields. Renewable energy research demonstrates a higher proportion of both general and open access publications, while data sharing remains sporadic, with few references to reusable datasets in publications. This presents a range of potential challenges, which were also elaborated upon in further detail in the study. While the use of OpenAlex ensures adherence to open data principles, there are also limitations, such as the potential for gaps and duplicates in the metadata, as well as difficulties in tracing implicit data sharing practices. Nevertheless, these findings already contribute to an understanding of the current state of openness in energy research and inform strategies within the NFDI4Energy consortium and for energy research to promote fair and transparent scientific practices.}, language = {en} } @misc{Lu2024, author = {Lu, Linna}, title = {Bibliometric Topic Analysis: Assisting Researchers in Identifying Research Trends and More}, series = {TK 4: Forschungsnahe Dienste und Open Science/ Bibliometrie - offen, lokal, global (05.06.2024, 14:00 - 15:30, Saal E / 2.

Current services tend to focus on bibliometrics as a research evaluation tool, although bibliometrics has the potential to offer much more. In today's fast-paced world of scientific publishing, researchers need to be able to quickly and efficiently navigate through vast amounts of information to identify emerging trends and gain research-relevant insights. Bibliometric topic analysis is a powerful complementary method that can help researchers meet this challenge. In this contribution, the methods, concepts, and tools of bibliometric topic analysis are presented and exemplary analyses of selected topic areas are carried out. The results of the analyses are illustrated with visualizations, thereby revealing the complex thematic landscapes, hidden patterns, and future research paths. Through this type of analysis, researchers can gain timely insights into research trends and identify potential cooperation partners, gaining numerous advantages for their research endeavors. Our library offers advisory services on bibliometric topic analysis, with the aim of integrating it into topic-specific research training, thereby significantly extending traditional research methods. We are aware of the potential challenges and limitations of this approach and emphasize responsible use of the associated methods, resources, and implications. The aim is to promote scientific research through the conscientious use of bibliometrics tailored to the specific needs of researchers.}, language = {de} }
