Bewertung der Softwarequalität von Forschungssoftware

IDEE

Software gewinnt in der Forschung immer mehr an Bedeutung. (...) Wir wollen untersuchen, welche Best Practices in der Softwareentwicklung angewandt werden und welche Bedeutung die Codequalität in Forschungssoftware hat. Die Ergebnisse werden einen Einblick in die aktuelle Codequalität geben und Möglichkeiten zur Verbesserung der Qualität und Korrektheit der verwendeten Programme aufzeigen. Konkret wollen wir die folgenden Forschungsfragen beantworten:

  • RQ1: Wie erheben, dokumentieren und analysieren Forscher Anforderungen an Forschungssoftware?
  • RQ2: Welche Prozesse befolgen Forscher und welche Teile beziehen sich auf Anforderungen?
  • RQ3: Welchen anforderungsbezogenen Herausforderungen stehen Forscher gegenüber?

ERGEBNIS

Es wurden Interviews durchgeführt, analysiert und die Ergebnisse zusammen mit den zukünftigen Herausforderungen und Visionen für Forschungssoftware in einer Veröffentlichung ausführlich dokumentiert.

Bajraktari, M. Binder, A. Vogelsang: "Requirements Engineering for Research Software: A Vision“, In: 32nd IEEE International Requirements Engineering (RE) 2024 conference, https://arxiv.org/abs/2405.07781

In dieser Veröffentlichung wird klar, dass es Handlungsbedarf gibt, um Fehler in der Software und mögliche falsche Schlussfolgerungen in der Forschung vermeiden zu können. Die Vision besteht darin, Bildungs- und Forschungslücken zu überbrücken, Software-Engineering in der Forschung zu fördern und Forscher zu befähigen, hervorragende Software zu entwickeln.

Establishing a modelling framework for agent-based models

with  Marijn van der Meij, Tim Reichenau, Andreas Bolten, Tony Reimann, Georg Bareth, and Karl Schneider

Agent-based models (ABMs) are known as a tool to model interactions between human agents in economics (Farmer and Foley, 2009) or social sciences (Bankes, 2002) or human-environment interactions (An, 2012). It is one of the methods to approach complex systems. Some even call them “a bridge between disciplines”‘ (Axelrod, 2006). ABMs are related to game theory; however, they can encompass more complex behaviour. Given their power to approach complex systems, we feel that ABMs should be part of the KPA’s repertoire of models to help answering pertinent questions relating to human-environment interactions within the Earth System Sciences. Eventually, ABMs could even be a link between the KPAs “Social and Economic Behavior” and “Intelligent Methods for Earth System Sciences”. ABMs require a thorough implementation to run at a reasonable speed. The (relatively) new language for data analysis, Julia (https://julialang.org/), promises such a framework for a successful implementation (https://github.com/juliadynamics/Agents.jl/). Thus, we suggest trying Julia’s capacity to provide a framework to implement ABMs. As a case study, we will use the research questions arising in the project A05 “Future roads” in the CRC 228 related to land-use change and development of a road network.

Establishing and testing a digital lab notebook

with Stephan Opitz

Electronic lab notebooks (ELN) are an important tool to ensure data safety and reproducibility of experimental results in a lab. It is part of a thorough research data management (https://fdm.uni-koeln.de/serviceangebot/servicekatalog-1). At the Faculty of Mathematics and Natural Sciences, we have the opportunity to test the software eLABJOURNAL. In this proposal, we suggest to test eLABJOURNAL in the Laboratory of the Institute of Geography within the working group Ecosystem Research and to report whether this software can be used more broadly within the KPA to e.g., exchange protocols between different working groups and coordinate our technical infrastructure (Großgeräte) more efficiently.

Establishing a framework for development of Shiny Apps for teaching

with Andreas Bolten

Shiny apps written in R (https://shiny.rstudio.com/) are interactive web apps. They can be used to teach e.g., statistics (https://stattlc.com/2021/08/17/ooh-shiny-r-shiny-apps-as-a-teaching-tool/) to beginners or for serious applications like reporting about systematic literature search according to PRISMA (https://estech.shinyapps.io/prisma_flowdiagram/.) We suggest (i) developing shiny apps for teaching within the KPA and (ii) creating teaching material that can serve to teach students to program such apps themselves. In order to deploy Shiny apps, a Shiny server is needed. To setup it, we kindly request the assistance of the KPA and in particular from Dr. Katja Sperveslage.

Dashboard Visualization for Atmospheric Rivers

The visualization of meteorological data requires effective and efficient interaction possibilities. Meteorological data have specific characteristics to be taken into account. Especially multiple aspects of data measurements on arctic atmospheric rivers. The use of visualization for publication purposes – in papers or online – requires a high amount of data accessibility and readability provided through a high number of filters and display options.

Our goal is to develop, implement and evaluate a novel dashboard visualization on meteorological data as well as to improve the given dashboard on atmospheric rivers designed during the “Visual Analysis Lab”. The output of the project can be used by all researchers in KPA.

Design and implementation of a soil-sediment database system for complex geoscientific and spatial data

Due to progress in experimental technology and computational processing, geoscientific research produces increasingly more and more complex data from an increasing number of various sources and methods.(…) In Geosciences, placing observations in their spatial context is very important. (…) A modular and scalable database system deployed on the organisational level of an institute-wide laboratory rather than a research project, may help overcome the aforementioned challenges. The proposed project seeks to develop an integrated database system for geoscientific research that integrates the data management in the course of the research process from fieldwork documentation to laboratory results. Moreover, collaboration between research groups of the Institute for Geography (mainly AG Bareth, AG Bogner, AG Mansfeldt, AG Schneider, AG Reimann) and participants of the Key Profile Area (KPA) (e.g. AG Dunai, AG Grunert, AG Melles and others) will be explored. The goals of database system development are to:

  • provide long-term storage of research data and metadata beyond the organisational and temporal limits of individual projects,
  • simplify fieldwork and laboratory documentation,
  • allow simple and comprehensive query of data records across different projects, spatial and temporal scales, using programming interfaces,
  • be modular and scalable and
  • fulfil the requirements of the DFG

New ground-based dataset input for developing a new machine learning self-supervised classification approach to identify cloud regimes.

Cloud mesoscale organization is crucial in determining cloud response to climate change, especially in the tropical region. Self-supervised machine learning (MLSV) method applied to satellite data successfully classifies cloud regimes in the trades during the EUREC4A campaign (Chatterjee et al., 2023). However, it still does not exploit the information from different observing geometries, like ship-based profiling observations. Model studies show that the evaporation of precipitation can play a crucial role in cold pool development, altering cloud spatial patterns and organization. We suggest preparing precipitation's evaporation rate (ER) measured from ship-based observations (Acquistapace et al., 2021) as input for MLSV. We will calculate ER by applying the method described by Tridon et al., 2017. First, we will use the mean cloud ER to understand better cloud regimes obtained using only satellite data. Finally, we will test the feasibility of including such data as input for the MLSV algorithm, hopefully revealing a new potential extension of the MLSV method that could benefit various applications and diverse scientific goals in intelligent methods for earth sciences.

Digitalisierung der Lehrsammlung des GeoMuseums

Das GeoMuseum des Instituts für Geologie und Mineralogie der Universität zu Köln beheimatet eine große Sammlung an Gesteinen, Mineralen und Fossilien. Einige dieser Stücke sind im Museumsraum ausgestellt und für die Öffentlichkeit zugänglich. Die meisten Stücke befinden sich jedoch in den Lagerräumen des Museums. Darunter befindet sich auch eine umfangreiche Lehrsammlung aus sedimentären, magmatischen und metamorphen Gesteinen, welche in der Vergangenheit intensiv für die Lehre genutzt wurde. Unser Ziel ist es, die Aufmerksamkeit unserer Dozierenden am Institut (und evtl. darüber hinaus) auf die Lehrsammlung zu erhöhen, in dem wir diese digitalisieren. 

Zur Digitalisierung wird derzeit ein Photogrammetrie-Labor in den Räumlichkeiten des GeoMuseums eingerichtet (u.a. mit Geldern des Albertus-Magnus Lehrpreises 2023). Voraussichtlich kann im neuen Jahr mit der Aufnahme der Lehrsammlung (etwa 350 Stücke) begonnen werden. Hierzu sollen die Stücke zuerst gewogen, dann fotografiert (aus mehreren Perspektiven zur Erstellung eines 3D-Modells) und petrographisch beschrieben werden. Die Daten und Informationen werden in einer digitalen Datenbank eingetragen und schließlich mit allen Dozierenden des Instituts geteilt.

Workshop COSMO 2024 "Pushing the boundaries of cosmogenic nuclides"

We support the COSMO 2024 workshop in Cologne (20-24 May 2024). This workshop is part of a biannual series of workshops, which developed from the ‘Nordic workshop on cosmogenic nuclides’ (last held in Norway 2018, 4NWCN, Bergen University), into a Pan-European workshop. After a corona-related break, the last workshop COSMO 2022 was hosted jointly by the University of Edinburgh and the University of Glasgow, UK. The convenors for COSMO 2024 in Cologne are Steven Binnie (UoC), Tibor Dunai (UoC) and Hella Witmann-Oelze (GFZ-Potsdam).
The scope of the workshop is to present and discuss novel developments in cosmogenic nuclide methodologies and applications to earth surface system sciences. This field of geochronometry has grown over the last several decades to become well recognised and established within the broader Earth Science community, and the broadening remit and increased profile of this workshop series reflects this.

Workshop zum Thema "Approaching complex systems: How do qualitative and quantitative methods contribute to climate change adaptation research?"

As our planet is challenged by manifold crises, concepts like complex systems and systems thinking are fundamental for many disciplines in the KPA and beyond. However, different disciplines have their own understanding and way to treat those concepts. In practice, systems thinking includes a broad array of qualitative and quantitative methods and tools designed to better understand system behaviours and intervene in the context of complexity and uncertainty. We suggest a workshop where these concepts can be discussed focusing on climate change adaptation. We aim at inviting experts from both, quantitative and qualitative areas to work intensively on controversial statements (part of the concept of the workshop which will be developed and sent to participants beforehand). This workshop will bring together different disciplines and intensify KPA’s links outside the Faculty and University, thus  increasing its national and international visibility.
