Daffodil: Strategic Support during the Information Search Process in Digital Libraries

Sowohl die rechnergestützte Informationssuche in einer realen Bibliothek als auch die in einer digitalen Bibliothek stellen heute immer noch ein zeitaufwändiges und damit teures Unterfangen dar. Als wesentliche Gründe können drei Problembereiche identifiziert werden. Zum Ersten existieren zahlreiche Zugangspunkte mit jeweils unterschiedlichen Formularen, Anfragesprachen und unterschiedlicher inhaltlicher Qualität. Zum Zweiten fehlt eine dringend benötigte anbieterübergreifende Integration der Informationen und Dienste. Zum Dritten schließlich wird der Benutzer durch die unbefriedigende Funktionalität nicht ausreichend in seinem Informationssuchprozess unterstützt. Alle diese Punkte führen letztendlich zu langwierigen und damit teuren Suchprozessen. Diese Dissertation stellt sich der Aufgabe, den oben genannten Problembereichen in geeigneter Weise zu begegnen und eine adäquate Lösung zu erarbeiten. Dazu erhält der Benutzer durch "strategische Unterstützung" in Form von verschiedenen integrierten Diensten von einem aktiven System eine Hilfestellung, um so sein Informationsbedürfnis effektiv und effizient befriedigen zu können. Die Ergebnisse dieser Arbeit, die durch eine ausführliche Evaluation belegt worden sind, bieten sowohl theoretische als auch praktische Lösungen zur Entwicklung und zur Nutzung von digitalen Bibliotheken: * Der theoretische Teil zeigt ein Modell für verteilte Bibliotheksdienste auf, strukturiert diese und stellt sie in einen Gesamtzusammenhang. Dadurch wird die Modellierung neuer Dienste erleichtert und ein positiver Nutzen kann schon im Vorfeld diskutiert werden. * Der praktische Teil basiert auf dem entwickelten Modell und ermöglicht * den Benutzern, effektiv und effizient einer umfassenden Literatursuche nachzugehen und diese auch nachhaltig zu verwalten. * den Entwicklern von digitalen Bibliotheken durch Zugriff auf eine Vielzahl von Basisdiensten darüber hinausgehende Dienste zu entwickeln. Insgesamt kann das DAFFODIL-System als Basisarchitektur für die Entwicklung und Evaluation von digitalen Bibliotheken verwendet werden und trägt somit zur wissenschaftlichen Forschung in diesem Bereich bei

DDI-FlatDB: Next steps

We analyzed our current data structures and working habits of, and with the DDI-FlatDB with respect to efficiency of data access and the effectiveness of the developer, adopting new DDI versions. For data structures within DDI we found internal links, directing forward and backward within a study as well as links to external sources, like institutions or controlled vocabulary. Instantiating these links lead currently to slow access times and to load large portions of XML snippets. In order to overcome this drawbacks the idea is to extend the DDI-FlatDB to instantiate all links within a link database based on Linked Open Data principles. This will lead to an efficient access within and across surveys. We will describe how we plan to store the links as triplets and what the advantages will be. Along adapting DDI and XML for the CESSDA CV Manager, we found, that the description of the mapping of DDI elements via XPaths to our entities is still a complex tasks and involves XPath creation and verification of results, which lead to inefficient turnaround times. We plan to create a specific editor for capturing the structure when editing XPaths, so the developing time will be more efficient and less error-prone

Enhancing FAIR Compliance in Research Data Infrastructures: Insights from Applications of the RDA FAIR Data Maturity Model and the F-UJI Automated FAIR Data Assessment Tool

We share experiences assessing KonsortSWD using two approaches (manual and automated assessments). We used the FAIR Data Maturity Model (RDA-FDMM), which proposes 41 FAIR indicators organized into three classes (essential, important, useful) and five assessment levels. We applied RDA-FDMM to KonsortSWD's PID service, aiming to assign PIDs to data elements below the study level (such as survey variables). The indicators were manually assessed using the pass-or-fail method. We used the F-UJI Tool to automatically assess the GESIS Search as a relevant repository in the context of KonsortSWD. Tools like F-UJI offer valuable feedback on how to improve FAIR scores by automated means. Our experience highlights the importance of evaluating both machine-readable and non-machine-readable elements. As the research ecosystem evolves, providing easily machine-readable metadata becomes increasingly important. We recommend adopting a "FAIR by design" approach early in product or service development to ensure FAIR principles are embedded in project outcomes.KonsortSWD is funded by the German Research Foundation (DFG) within the framework of the NFDI – project number: 442494171

Metadata Schema x-econ Repository

Since May 2017, the x-hub project partners OVGU Magdeburg, University of Vienna, and GESIS dispose of a new repository, called x-econ (https://x-econ.org). The service is dedicated to all experimental economics research projects to disseminate user-friendly archiving and provision of experimental economics research data. The repository x-econ contains all necessary core functionalities of a modern repository and is in a continuous optimization process aiming at functionality enhancement and improvement. x-econ is also one pillar of the multidisciplinary repository x-science (https://x-science.org). The present documentation, which is primarily based on the GESIS Technical Reports on datorium 2014|03 and da|ra 4.0, lists and explains the metadata elements, used to describe research information

Assigning Creative Commons Licenses to Research Metadata: Issues and Cases

This paper discusses the problem of lack of clear licensing and transparency of usage terms and conditions for research metadata. Making research data connected, discoverable and reusable are the key enablers of the new data revolution in research. We discuss how the lack of transparency hinders discovery of research data and make it disconnected from the publication and other trusted research outcomes. In addition, we discuss the application of Creative Commons licenses for research metadata, and provide some examples of the applicability of this approach to internationally known data infrastructures.Comment: 9 pages.

25th annual computational neuroscience meeting: CNS-2016

The same neuron may play different functional roles in the neural circuits to which it belongs. For example, neurons in the Tritonia pedal ganglia may participate in variable phases of the swim motor rhythms [1]. While such neuronal functional variability is likely to play a major role the delivery of the functionality of neural systems, it is difficult to study it in most nervous systems. We work on the pyloric rhythm network of the crustacean stomatogastric ganglion (STG) [2]. Typically network models of the STG treat neurons of the same functional type as a single model neuron (e.g. PD neurons), assuming the same conductance parameters for these neurons and implying their synchronous firing [3, 4]. However, simultaneous recording of PD neurons shows differences between the timings of spikes of these neurons. This may indicate functional variability of these neurons. Here we modelled separately the two PD neurons of the STG in a multi-neuron model of the pyloric network. Our neuron models comply with known correlations between conductance parameters of ionic currents. Our results reproduce the experimental finding of increasing spike time distance between spikes originating from the two model PD neurons during their synchronised burst phase. The PD neuron with the larger calcium conductance generates its spikes before the other PD neuron. Larger potassium conductance values in the follower neuron imply longer delays between spikes, see Fig. 17.Neuromodulators change the conductance parameters of neurons and maintain the ratios of these parameters [5]. Our results show that such changes may shift the individual contribution of two PD neurons to the PD-phase of the pyloric rhythm altering their functionality within this rhythm. Our work paves the way towards an accessible experimental and computational framework for the analysis of the mechanisms and impact of functional variability of neurons within the neural circuits to which they belong
