Foreword
Hi. Welcome to our bi-annual Research Report. During the six months that this report spans, our team of research scientists, research engineers, survey specialists, analysts, design researchers, and our community officer alongside our research fellow, formal collaborators, and contractors led or significantly supported more than 30 projects and initiatives to support the development of new technologies and inform governance decisions in the Wikimedia Movement.
We continued to invest in strengthening the Wikimedia research communities. The team organized Wiki Workshop, the flagship event of the year for the Wikimedia research communities to engage in the research and scientific discourse around the Wikimedia projects; the Monthly Research Showcases to provide the space for the Wikimedia research community to showcase their latest work; the Research Fund through which, in collaboration with the Community Resources team, the team disseminated 261,730 USD to 8 accepted research proposals for funding; the Wikimedia Foundation Research Award of the Year through which we recognize novel research which has high potential for significant impact on the Wikimedia projects; and held more than 30 one-on-one public Office Hours to consult with the community members and the friends of the Wikimedia Movement on a variety of topics and questions. I am thankful to everyone who supported our work to strengthen the Wikimedia research community, especially in this moment where many research institutions and researchers can particularly benefit from the continuity of our services and support.
We made informed decisions about how to approach AI development in support of Wikipedia editors. At the Wikimedia Foundation we strive to take an intentional approach to opportunities and challenges and for me our new AI Strategy for Editors is a good example of that intentionality. I am proud that we prioritized not only what we will do, but also why, and how we will do that, embracing trade-offs that we had to make, and publicly communicating about our direction. I hope that the open knowledge institutions find strength and support through our approach and I hope that more people and organizations join us in our efforts to nurture the open knowledge ecosystem.
We are further investing in understanding Wikipedia reader needs, building on almost a decade long research on this front (See reports No. 1, No. 4, and No. 9 for some examples). What makes this moment particularly important for revisiting this line of research are the trends with regards to how online information is distributed and regulated. The risk of further intermediation because of AI is present and at the same time because many high traffic online platforms and tools are not prioritizing human agency in learning, Wikipedia has a unique opportunity to recognize this moment and experiment to help more readers access neutral point of view encyclopedic content and engage with knowledge directly through the platform, while their privacy is respected. The understanding through research such as the focus on discovery needs and motivations will equip us for further informed research, experimentation, and feature development in support of Wikipedia readers.
We are investing in understanding contributor motivations. The Wikimedia Foundation’s Multigenerational strategy calls on us to invest in fueling volunteer growth and a key component of that growth is motivating volunteers to contribute to Wikipedia “in perpetuity”. The focus on volunteer motivation is tightly related to the field of incentive design, which spans multiple fields of research including psychology, behavioral economics, computer science and more. This is a very important and novel area of research in that while the state of research is relatively mature when it comes to incentive design in for-profit endeavors, it is much less developed considering large scale social good products such as Wikipedia. I look forward to learning from the line of research started and for us to support informed decision making on the product and community governance and policy fronts through this work.
I now invite you to read the rest of this report to learn more about the Projects, the People on the team, Events, Donors, Collaborations, and Trends we watch.

Presentations and Keynotes
Through the following presentations and keynotes, we engaged with the research and scientific communities, and supported the Wikimedia communities in advancing their work.
We presented at the Wikimedia Youth Conference 2025 on Participation on Wikimedia Projects, discussing what we know about young readers, editors, and administrators, and future plans for young audience research. Slides
We gave a seminar titled A Tour through Source Reliability in Wikipedia at the Faculty of Engineering of the Free University of Bolzano.
We attended the ICWSM 25 conference to present ongoing work on article maintenance templates as part of a workshop on Computational Approaches to Content Moderation and Platform Governance.
We attended the Wikimedia+Libraries International Convention 2025 and presented a talk titled Wikipedia's role in the Artificial Intelligence ecosystem and the fight against disinformation, highlighting the critical importance of Wikipedia in supporting underrepresented languages on the web and its unique position in promoting reliable, multilingual knowledge in the age of AI. Slides
We attended CHI 2025 where we hosted a Wikimedia Research booth to strengthen the Wikimedia research communities by raising awareness about Wikimedia research in the CHI community.
We attended WWW 2025, which has published much Wikimedia research and is where WikiWorkshop was co-located for several years. This year, the conference was held in Sydney, Australia, which also enabled us to reach a community of researchers with whom we generally have fewer opportunities for co-location.
We gave a talk in Wikiherramientas in support of Wikimedistas de Uruguay showcasing several research findings from the work of the team to raise awareness among Wikimedia affiliates about the potential for turning research insights into changes on the ground. Video
Office Hour Series
We held over 30 one-on-one office hours to support researchers by answering questions about proposed or ongoing projects, guiding dataset access and analysis, sharing insights on Wikimedia Research team initiatives, exploring potential collaborations, and more. Learn more
Research Showcases
Our Monthly Research Showcases featured diverse presentations on content integrity, editor motivations, gender gaps, reader attention and curiosity, and Wikipedia Admin recruitment, retention, and attrition. Learn more
Wiki Workshop
We held the 12th edition of Wiki Workshop, for the first time over two days. More than 250 participants joined us in this year's edition, composed of researchers, Wikimedia volunteers, WMF staff, and more. We received 62 submissions for the research track and held new programming, including two AMA sessions with Wikipedia administrators.
If you missed the event, worry not! You can review the schedule, check out the accepted extended abstracts, and even watch the recorded sessions.
Research Fund
This year, we made some changes to the Research Fund in order to better support the research community and increase the impact of the funds we give. We revamped the fund to include three proposal types (standard 12‑month research, extended up to 24 months with a possible third year, as well as event and community building), higher funding limits (up to 150K for extended research), a one‑stage review process, and clearer eligibility criteria. We received 61 submissions, funded 8 projects, distributing a total amount of over 260,000 USD among these projects.
WikiNLP
We worked on co-organizing the second edition of WikiNLP which will take place as part of ACL 2025. The event will create a space for showcasing Wikimedia's contributions to the NLP community and highlighting approaches to ensure the sustainability of this relationship for years to come.
WMF-RAY
Since 2021 we have recognized novel research that has the potential to have significant impact on the Wikimedia projects or the research space. We worked on award selection and organized the award ceremony. Learn more about the winners and watch the award ceremony if you missed it. Congratulations to the 2025 winners.
The people on the Research team
New members
Debra Kumar joined us in April 2025 as Manager, User Experience Research. Debra is a mixed-methods researcher with a background in computer science and psychology (B.S., Iowa State University) and a Masters’ in Human-Computer Interaction (University of Michigan). Prior to joining Wikimedia, Debra worked for 11 years as a User Experience Researcher at Google, where she worked on Gmail and Google Search. In this role, she led researchers and research across countries to understand user needs and inform product direction. On Google Search, this research focused on understanding the role that video plays in information-seeking online and when and why users prefer video or visual content over text-based information sources – as well as understanding young people’s information-seeking behaviors and preferences both on Google Search and off. Within the Wikimedia Research team, she is managing the Design Research team and also contributing to the research community initiatives within the broader Research team.
Collaborations
The Research team's work has been made possible through the contributions of our past and present formal collaborators. During the last six months we did not create new formal collaborations. Instead we focused more heavily on wrapping up existing collaborations, and we initiated internal conversations about which areas of research we want to pitch for new formal collaborations. We expect to gradually start adding formal collaborations in the coming six months.
We also want to take this opportunity to thank Benjamin Mako Hill (University of Washington) for extensively supporting our team's efforts on two major fronts. Mako served as a Research Fund co-chair during the past six months as well as the Award co-chair for the WMF Research Award of the Year (WMF-RAY).
To inquire about becoming a formal collaborator, please tell us more about yourself and your interests.
