Introducing LimeSurvey at WI

Surveys are an important method for data collection. Whether it is for conducting internal assessments, gathering feedback, or collecting valuable research data, a reliable survey tool is an integral piece in the methodological toolkit of any researcher. Using different survey tools for different projects leads to differences in the quality of data collection and unnecessary licensing costs. In order to find a more sustainable solution, the Methods Lab assessed some of the most popular survey tools with the aim of finding the ideal one to cater to the specific needs of the Weizenbaum Institute’s research groups and administrative departments. Important to us was to select a user-friendly, open-source survey tool suitable for research that can be hosted on our own servers

In this blog post, we introduce our choice: LimeSurvey. It is a free, open-source survey software with a strong commitment to data protection. It offers a versatile platform for data collection, making it ideal for researchers, academic institutions, and organizations of all sizes. In doing so, we hope that the insights from our survey tool comparison will prove useful to researchers and institutions beyond our own. 

Here are some of the distinctive advantages that we were able to identify, making LimeSurvey a compelling choice for research and data collection:

  • Cost-Effective and Open Source: LimeSurvey is open source, meaning, it is available for free when hosted on your own servers, thereby eliminating the need for costly licensing fees.
  • Data Protection: LimeSurvey prioritizes data privacy – a particular advantage appreciated by our IT department due to its compliance with the GDPR. Its servers are strategically located in Germany and Finland, ensuring adherence to stringent European data protection regulations.
  • User-Friendly Integration: LimeSurvey seamlessly integrates with existing user accounts, simplifying the onboarding process without requiring additional account setup.
  • Suitable for Research: LimeSurvey is designed with research needs in mind. It offers a wide range of features, including unlimited projects and administrators/accounts. This flexibility makes it suitable for both simple and complex research projects.
  • No Artificial Limits: LimeSurvey imposes no artificial limitations on user accounts, participants, or projects.

The WI LimeSurvey installation can be accessed by members of the institute here: https://limesurvey.weizenbaum-institut.de/index.php/admin/. Its use is documented in the internal Wiki.

Happy surveying!

Workshop Recap: Theory Construction – Building and Advancing Theories for Empirical Social Science (September 14, 2023)

On September 14th, 2023, the Methods Lab organized a workshop on the rationale and methodology of theory building in empirical research. The workshop was conducted by Adrian Meier (U of Erlangen-Nürnberg) and aimed to provide participants with an orientation for working with theories in a meaningful way that provides a foundation for empirical research.

In the first section of the workshop, Adrian outlined what theories are and how they relate to the overarching mission of science. The introduction focused on the differentiation between theories, concepts, constructs, and models and addressed the interplay between theories and empirical research.

After this introduction, the focus shifted to challenges and problems of social scientific theorizing. Participants were given the opportunity to add issues and questions they identified in the past when working with theories. Most prominently, they mentioned confusion due to different terminology that is used for specific concepts (i.e., synonymy and ambiguity), the “moving target” problem (as phenomena are changing while they are being studied), and the lack of incentivization to focus on theory in the formalized infrastructure of empirical research. Adrian elaborated on some of the underlying issues uniting many of these challenges: Theories are underdetermined by evidence, concepts and measurement instruments are rarely validated, and manipulations in experimental research are not precise enough.

In the last section of the workshop, participants learned about a recently proposed Theory Construction Methodology (Borsboom et al., 2021) and took part in an accompanying exercise. They were asked to read a one-pager summarizing crucial elements of the Mood Management Theory, a popular theory in the field of media psychology. Within this text, they should identify statements about phenomena the theory is supposed to explain, data that supported it (or not), as well as the theoretical statements (e.g., premises, propositions) themselves, to increase participants‘ sensitivity in differentiating between these elements in their own work. Lastly, Adrian gave an outlook on how theories can be formalized and how theory construction can be crucially fostered by non-confirmatory research practices.

The workshop was a great and unconventional addition to this year’s series of workshops organized by the Methods Lab. Adrian structured and executed it brilliantly and gave participants – who were associated with various fields of research and very engaged – lots of room for discussions.

We would like to thank Adrian for his thorough and inspiring workshop and hope he will contribute to the Methods Lab program again in the future. In the meantime, we recommend following him on X for updates on his research!

Workshop Recap: Whose Data Is It Anyway? Ethical, Practical, and Methodological Challenges of Data Donation in Messenger Groups Research (August 30, 2023)

On August 30th, 2023, the Methods Lab and Olga Pasitselska (U of Groningen) organized the workshop on data donation in messaging groups research. The workshop intended to tackle practical and ethical issues behind data collection, processing, and dissemination in the research of closed messaging groups. We asked four colleagues to share their experiences and struggles and provide their solutions for closed chat groups research. The invited speakers, Sérgio Barbosa (U Coimbra), Katharina Knop-Hülß (HMTMH Hannover), Connie Moon Sehat (Hacks/Hackers), and Julian Kohne (GESIS), paved the way for better conceptualization of messaging groups and application of tailor-made ethical and practical solutions. The workshop allowed for a cross-field discussion of ad-hoc developments in closed groups research and provided many insights for the audience, speakers, and organizers.

Sérgio Barbosa explained his approach of joining activist WhatsApp groups in Brazil. Sérgio suggested that informed consent cannot be assumed as a one-off solution: instead, one should go beyond the check-list of ethical guidelines and learn by doing and negotiating with the group members. When joining these types of groups, researchers should clearly state the purposes of the research and disclose their identity, and also share the outcome of the research and promote it in the local community as well. Different approaches should be taken, depending on the type of groups: for example, pro-democracy groups and extremist groups should be treated differently, independent of the group size.

Dr. Katharina Knop-Hülß shared insights about studying non-professional secondary groups (e.g., choir, sport, volunteer groups) with her highly unobtrusive and highly invasive research approach of scraping chats’ content. Since these groups were representative of intimate environments of everyday communication, they can be considered as “safe spaces”, closed from the public eye. To account for the sensitive nature of the data collection, Katharina used an opt-in approach, provided pseudonymized chat logs to the participants before they consented to participate, and complied with the requirement not to share this data with anyone beyond the research team, even after the data was pseudonymized.

Julian Kohne introduced his digital platform for WhatsApp data donation that automatically cleans and anonymizes the data, reducing researchers’ exposure to and intervention in the raw data. In his research, Julian takes a participant-centered approach: the data collection tool is designed to maximize usability and control of the data for research participants. They can pre-process the data in a way that allows them to review the chat logs and decide what exactly they want to donate, deleting undesirable pieces of data, up to the possibility of deleting time stamps and other meta-data. With that, the tool also allows researchers to track how much and what types of data was deleted.

Dr. Connie Moon Sehat presented the meta-review of closed messaging apps research that aimed to determine what are the conditions in terms of indexed invites, group size, discussion topics, or other aspects of closed groups that make them arguably public or private. Adding to the previous speakers’ examples of their research with activist/public and hobby and friends/private types of groups, the review summarized the discussed points and provided a framework for mapping chat groups according to the multiple parameters. Whether researchers scraped the groups without entering them, entered with invitation, disclosed or not their identity and research interest, depended on the nature of the groups and public interest that can justify researchers’ intervention into the closed communication spaces. Connie also stressed the possible differences in perceptions of groups’ “publicness” between users, researchers, and platforms, that also should be taken into account.

After four presentations, we continued the discussion with the online and offline audience, addressing the issues of generalizability of messaging data (what slice of the “natural” social interaction are we looking at here?), the role of language, and the differences between long- and short-term groups. We also discussed what is the role of the researcher in the automated versus manual data collection process, and how participants can benefit from data donation.

The workshop provided theoretical and practical insights for messaging groups research and outlined future directions for collaboration in creating the guidelines for ethical closed messaging research and data donation.

Workshop Recap: Introduction to Topic Modeling (June 15, 2023)

On June 15, the Methods Lab organized the workshop Introduction to Topic Modeling in collaboration with the research group Platform Algorithms and Digital Propaganda. The workshop aimed to provide participants with a comprehensive understanding of topic modeling – a machine-learning technique used to determine clusters of similar words (i.e., topics) within bodies of text. The event took place at the Weizenbaum Institute in a hybrid format, bringing together researchers from various institutions.

The workshop was conducted by Daniel Matter (TU Munich) who guided the participants through basic concepts and applications of this method. Through theory, demonstrations, and practical examples, participants gained insight into commonly used algorithms such as Latent Dirichlet Allocation (LDA) and BERT-based topic models. The workshop enabled participants to assess the advantages and drawbacks of each approach, equipping them with a foundation in topic modeling while, at the same time, providing plenty of new insights to those with prior expertise.

During the workshop, Daniel explained the distinction between LDA and BERTopic, two popular topic modeling strategies. LDA, or Latent Dirichlet Allocation, a commonly used method for topic modeling, operates as a generative model and treats each document as a mixture of topics. LDA aims to determine the topic and word distributions that maximize the probability of generating the documents in the corpus. With LDA, as opposed to BERTopic, the number of topics must be known beforehand.

BERTopic, on the other hand, belongs to the category of Embeddings-Based Topic Models (EBTM), which take a different approach. Unlike LDA, which treats words as distinct features, BERTopic incorporates semantic relationships between words. BERTopic follows a bottom-up approach, embedding documents in a semantic space and extracting topics from this transformed representation. Unlike LDA, which can be applied to short and long text corpora, BERTopic generally works better on shorter text, such as social media posts or news headlines.

When deciding between BERTopic and LDA, it is essential to consider the specific requirements of the text analysis. BERTopic’s strength lies in its flexibility and ability to handle short texts effectively, while LDA is preferred when strong interpretability is needed.

With this workshop, we at the Methods Lab hope to have provided our attendees with a solid understanding of topic modeling as a method. By exploring the concepts, applications, and advantages of each approach, these tools can be used to unlock hidden semantic structures within textual data, enabling researchers to employ them in various domains and facilitating tasks such as document clustering, information retrieval, and recommender systems.

A big thank you to Daniel for inducting us into the world of topic modeling and to all our participants!

Our next workshop, Whose Data is it Anyway? Ethical, Practical, and Methodological Challenges of Data Donation in Messenger Groups Research, will take place on August 30, 2023. See you there!

Workshop Recap: From Civic Tech to Science – Reimagining Science-Society Relations (July 6, 2023)

On July 6, Nicolas Zehner gave the workshop From Civic Tech to Science: Reimagining Science-Society Relations at the Weizenbaum Institute. Civic tech encompasses a diverse array of empowering technologies that enable democratic participation by allowing citizens to engage with societal issues and contribute to positive change. What insights can science gain from civic tech initiatives? How can they contribute to inclusive knowledge creation? And how can the design of these initiatives help rethink science-society relations? Those were some of the key questions that guided this workshop.

The workshop involved three introductory position statements, each shedding light on different aspects of civic tech’s impact. The position statement on “The Journalism of Things,” exemplified by projects like “Radmesser” and “Bienenlive,” demonstrated how civic tech can impact citizen behavior, raise topic visibility, and foster transdisciplinary knowledge. Dr. Beatrice Jetto’s position statement, “Blockchain-based Civic Tech Ecosystem: Bridging the Gap Between Research and Practice Objectives”, highlighted the potential of blockchain-based civic tech in making citizen participation in urban development more inclusive and transparent. Furthermore, Nicolas Zehner’s statement position, “AI, Environmental Protection, and the Promise of Participation”, discussed how Artificial Intelligence (AI) can serve as a platform for reimagining science-society relations and a gateway to thinking about more global issues by reintroducing the concept of “awareness of uncertainty” as a form of knowledge.

Following the position statements, the workshop engaged participants in group work sessions, facilitating discussions on knowledge transfer beyond conventional science communication. Collaboratively, they explored ways to create infrastructures that foster collaboration and include data subjects, avoiding the reproduction of existing power structures and ensuring equitable civic tech initiatives.

Workshop Recap: DSA – Data Access for Research (June 21, 2023)

Data is an invaluable asset for scientific research. However, accessing platform data for academic purposes has become increasingly challenging, particularly with the closure of free access to APIs like Twitter’s. Recognizing the significance of data accessibility for research, the Weizenbaum Institute organized the workshop Datenzugang für die Forschung – Der Digital Services Act (DSA) in collaboration with the European New School of Digital Studies (ENS) to explore the potential of the upcoming Digital Services Act (DSA) in facilitating data access for academic research.

The DSA is set to bring about improvements in data access for researchers under Article 40. However, the DSA’s regulations must be thoughtfully implemented at the national level to achieve these goals fully. With the closure of free access to Twitter’s API, there is an urgency to find robust solutions to enable researchers to access platform data for scientific inquiry. The DSA, expected to come into force in February 2024, holds promises to provide avenues for researchers to obtain the data they need for their academic research. Still, it also brings about its own set of challenges.

The workshop aimed to foster an open forum where researchers from diverse disciplines, particularly those who work or plan to work with platform data, could come together to provide recommendations for the effective implementation of the DSA. Organized by Ulrike Klinger (ENS) and Jakob Ohme (WI) and supported by the Stiftung Mercator, the workshop addressed crucial questions surrounding data access requests, eligible data, and the verification process by authorities and platforms.

The workshop started with a welcoming address from Ulrike Klinger. Jakob Ohme then provided an overview of the DSA’s Article 40, shedding light on its potential implications for researchers. This was followed by presentations on the DSA’s implementation in Germany by Gökhan Cetintas from the Bundesministerium für Digitales und Verkehr and Andrea Sanders-Winter from the Bundesnetzagentur, who offered insights into the data access rules under the DSA.

After a coffee break, Jessica Gabriele Walter from Aarhus University presented on DSA40 and scholarly networks in other EU countries, providing a broader perspective on data access challenges and solutions. Richard Kuchta from Democracy Reporting International later delved into “The Data Access Problem” and emphasized the necessity of a vetting process to ensure data security and accuracy.

The latter part of the workshop involved group work in which participants engaged in the discussion and expansion of a policy paper draft prepared by the Weizenbaum Institute and ENS, based on inputs from an early expert round. The goal was to develop actionable recommendations that would benefit the research community in Germany and the EU. Breakout sessions centered on topics like “Vetting Access,” “Access Modes,” and “Infrastructure,” allowing participants to delve deeper into specific aspects of data access.

The workshop brought together an interdisciplinary group of researchers with a shared vision: enabling access to platform data for academic purposes. By combining their expertise and perspectives, participants crafted recommendations for the effective implementation of the DSA, ensuring that data access for research remains equitable and secure. As the DSA comes into force and takes shape, the outcomes of this workshop are expected to serve as a significant step forward in fostering inclusive dialogue on the future of data accessibility.
