In diesem Beitrag widmen wir uns der Frage, welche Schritte unternommen werden müssen, um Skripte, die bei der Aufbereitung und/oder Auswertung von Forschungsdaten Anwendung finden, so FAIR wie möglich zu gestalten. Dabei nehmen wir sowohl Reproduzierbarkeit, also den Weg von den (Roh)daten zu den Ergebnissen einer Studie, als auch Wiederverwertbarkeit, also die Möglichkeit, die Methoden einer Studie mittels des Skripts auf andere Daten anzuwenden, in den Fokus und beleuchten dabei die folgenden Aspekte: Arbeitsumgebung, Datenvalidierung, Modularisierung, Dokumentation und Lizenz.
In unserem Beitrag diskutieren wir Aspekte einer Forschungsdateninfrastruktur für den wissenschaftlichen Alltag auf Projektebene und argumentieren für eine Unterstützung von Projekten während der Erfassung und Bearbeitung von Daten, d. h. vor deren endgültiger Veröffentlichung. Dabei differenzieren wir zwischen Projekten, deren primäres Ziel es ist, eine Ressource aufzubauen (ressourcenschaffende Projekte, kurz RP) und solchen, die zur Beantwortung einer konkreten Forschungsfrage Daten sammeln und auswerten (Forschungsprojekte, kurz FP). Wir argumentieren dafür, dass bei den offenkundigen Unterschieden zwischen beiden Projektarten die grundsätzlichen Ansprüche an das alltägliche Forschungsdatenmanagement im Kern sehr ähnlich (wenn auch unterschiedlich akzentuiert und skaliert) sind. Diese Ähnlichkeit rührt nicht zuletzt daher, dass im Rahmen von FP gesammelte Daten in Bezug auf das Projektziel primär Mittel zum Zweck sein mögen, sie jedoch bereits im Arbeitsprozess in unterschiedlichem Maß von unterschiedlichen Beteiligten genutzt werden. Wir gehen konkret auf die Aspekte Datenorganisation und -verwaltung, Metadaten, Dokumentation und Dateiformate und deren Anforderungen in den verschiedenen Projekttypen ein. Schließlich diskutieren wir Lösungsansätze dafür, Aspekte des Forschungsdatenmanagements auch in (kleineren) Forschungsprojekten nicht post-hoc, sondern bereits in der Projektplanung als Teil der alltäglichen Arbeit zu berücksichtigen und entsprechende Unterstützung in der Forschungsinfrastruktur vorzusehen.
Signposts for CLARIN
(2021)
An implementation of CMDI-based signposts and its use is presented in this paper. Arnold, Fisseni et al. (2020) present signposts as a solution to challenges in long-term preservation of corpora. Though applicable to digital resources in general, we focus on corpora, especially those that are continuously extended or subject to modification, e.g., due to legal injunctions, but also may overlap with respect to constituents, and may be subject to migrations to new data formats. We describe the contribution signposts can make to the CLARIN infrastructure, notably virtual collections, and document the design for the CMDI profile.
CMDI Explorer
(2021)
We present CMDI Explorer, a tool that empowers users to easily explore the contents of complex CMDI records and to process selected parts of them with little effort. The tool allows users, for instance, to analyse virtual collections represented by CMDI records, and to send collection items to other CLARIN services such as the Switchboard for subsequent processing. CMDI Explorer hence adds functionality that many users felt was lacking from the CLARIN tool space.

This paper addresses long-term archival for large corpora. Three aspects specific to language resources are focused, namely (1) the removal of resources for legal reasons, (2) versioning of (unchanged) objects in constantly growing resources, especially where objects can be part of multiple releases but also part of different collections, and (3) the conversion of data to new formats for digital preservation. It is motivated why language resources may have to be changed, and why formats may need to be converted. As a solution, the use of an intermediate proxy object called a signpost is suggested. The approach will be exemplified with respect to the corpora of the Leibniz Institute for the German Language in Mannheim, namely the German Reference Corpus (DeReKo) and the Archive for Spoken German (AGD).
The perception of prosodic prominence is influenced by different sources like different acoustic cues, linguistic expectations and context. We use a generalized additive model and a random forest to model the perceived prominence on a corpus of spoken German. Both models are able to explain over 80% of the variance. While the random forests give us some insights on the relative importance of the cues, the general additive model gives us insights on the interaction between different cues to prominence.
A frequently replicated finding is that higher frequency words tend to be shorter and contain more strongly reduced vowels. However, little is known about potential differences in the articulatory gestures for high vs. low frequency words. The present study made use of electromagnetic articulography to investigate the production of two German vowels, [i] and [a], embedded in high and low frequency words. We found that word frequency differently affected the production of [i] and [a] at the temporal as well as the gestural level. Higher frequency of use predicted greater acoustic durations for long vowels; reduced durations for short vowels; articulatory trajectories with greater tongue height for [i] and more pronounced downward articulatory trajectories for [a]. These results show that the phonological contrast between short and long vowels is learned better with experience, and challenge both the Smooth Signal Redundancy Hypothesis and current theories of German phonology.
The current paper presents a corpus containing 35 dialogues of spontaneously spoken southern German, including half an hour of articulography for 13 of the speakers. Speakers were seated in separate recording chambers, mimicking a telephone call, and recorded on individual audio channels. The corpus provides manually corrected word boundaries and automatically aligned segment boundaries. Annotations are provided in the Praat format. In addition to audio recordings, speakers filled out a detailed questionnaire, assessing among others their audio-visual consumption habits.
