Věra Jourová
Vice President of the European Commission for Values and Transparency
Keynote | 5 October | 9:00 |
Keynote
Věra Jourová is currently Vice President of the European Commission for Values and Transparency and deals with democracy, rule of law, media pluralism and fight against disinformation. From 2014 to 2019, she served as EU Commissioner for Justice, Consumers and Gender Equality. In 2014, before arriving to the European Commission, Ms Jourová held the position of Minister for Regional Development in the Czech Republic. Previous to this, from 2006 to 2013, she worked in her own company as an international consultant on European Union funding, and was also involved in consultancy activities in the Western Balkans relating to the European Union Accession.

Ricardo Baeza-Yates
Director of Research
Institute for Experiential AI, Northeastern University, USA
Keynote | 5 October | 15.30 |
„Bias in Search and Recommender Systems“
Ricardo Baeza-Yates is Director of Research at the Institute for Experiential AI of Northeastern University. Before, he was VP of Research at Yahoo Labs, based in Barcelona, Spain, and later in Sunnyvale, California, from 2006 to 2016. He is co-author of the best-seller Modern Information Retrieval textbook published by Addison-Wesley in 1999 and 2011 (2nd ed), that won the ASIST 2012 Book of the Year award. From 2002 to 2004 he was elected to the Board of Governors of the IEEE Computer Society and between 2012 and 2016 was elected for the ACM Council. In 2009 he was named ACM Fellow and in 2011 IEEE Fellow, among other awards and distinctions. He obtained a Ph.D. in CS from the University of Waterloo, Canada, in 1989, and his areas of expertise are web search and data mining, information retrieval, bias on AI, data science and algorithms in general.
In his presentation, Ricardo will cover all biases that affect search and recommender systems. They include biases on the data, the algorithms as well as the user interaction, in particular the ones related to relevance feedback loops (e.g., ranking and personalization). In each case he will cover the main concepts and when known, the techniques to ameliorate them, as well as biases that might be product of the evaluation methods used. Finally, he will also explore the cognitive biases involved.
Angella Ndaka
The Centre for Africa Epistemic Justice
University of Otago, Newzealand
Keynote | 6 October | 9.00 |
„Inclusion by whose terms? When being in doesn’t mean digital and web search inclusion“
Angella Ndaka is an early career researcher at the University of Otago (New Zealand), Winner of Women in AI Awards APAC 2023 and among the top 100 women in AI Ethics List 2023. Her PhD research focused on sustainable AI techno-futures. Moreover, she heads the Centre for Africa Epistemic Justice, a think tank following her “quest for Africa to find its legitimate place in the face of the current and future technological revolution.”
In her talk, Angella will show how AI can impact different communities, landscapes, and sectors differently, and how industry, governments, and organizations may adapt, innovate, and strategize to respect the values of the wider society.
Christoph Schuhmann
Computer Scientist, Teacher, Co-Founder of LAION e.V., Germany
Keynote | 4 October | 13.15 |
„Democratizing AI through community organizing“
Christoph Schuhmann is an educator and computer scientist who co-founded the German non-profit organization LAION e.V., which strives to democratize state-of-the-art AI research and models. He studied computer science, physics, and psychology at the University of Vienna. Before actively working on AI, he produced the documentary „Schools of Trust“ about schools where kids can learn what they are curious about, without mandatory curricula, grades, or other extrinsic rewards. In the past 10 years, Schuhmann has advised over 50 start-up groups for such schools on education and business matters, completely for free (as his „hobby“), to accelerate the growth of this movement. Nowadays, Schuhmann works as a tenured high school teacher and spends his free time organizing LAION’s community with thousands of scientists, developers, and engineers, who are united by one common goal: making state-of-the-art AI models openly accessible for everyone in the world, as a humanitarian right.
In this talk, he’ll delve into the vital role of open-source AI and grassroots development in democratizing AI benefits. Open-source AI enables broader participation, transparency, and innovation, which is crucial in mitigating the monopolistic control of AI by a few corporations. This grassroots approach fosters inclusivity, allowing citizens, businesses, and organizations to actively contribute to and benefit from AI advancements. He will explore the work of the Large-Scale Artificial Intelligence Network (LAION), a non-profit advocating for a publicly funded supercomputer to nurture large-scale, open-source AI models. LAION’s efforts, such as developing openCLIP and OpenAssistant, underscore the potential of open-source AI in offering accessible, non-profit alternatives. His argument: By democratizing AI, we can ensure the technology’s benefits reach all corners of society, fueling a more equitable future.
Industry Track “Alternative Search Engines”
Colin Hayhurst
CEO, Mojeek, United Kingdom
Industry Track “Alternative Search Engines”
| 5 October | 17.00 |
„Web Scale Search from the Ground Up: Establishing a Viable Alternative to Big Tech.“
Colin Hayhurst is the Chief Executive Officer of Mojeek Limited, a fully remote company with its roots in the UK. Mojeek is an international web search engine, used globally, that has no dependencies on any other company. With no-tracking Mojeek offers an alternative to proposition and solution to users and API customers alike. Colin has significant commercial and technical experience in startups, academia and industry. He has been a co-founding CEO or CTO of several startups in high-performance computing, web-infrastructure and machine learning respectively. He has conducted R&D in high energy physics, including contributing to design work for the CERN LHC beam dump and ATLAS detector.
In his talk, Colin will outline the very different path taken by Mojeek to build and establish a viable web scale international search engine. Mojeek is a commercial alternative to Big Tech, with a very different proposition, most notably no-tracking. He will discuss the technical challenges at Mojeek, including how one delivers a fast user and API customer service, for an index of over 7 billion pages. The business model and guiding principles on which Mojeek is based, and designed, shall be explained.
Anke Meinders
Managing Director of fragFINN e.V., Germany
Industry Track “Alternative Search Engines”
| 5 October | 17.00 |
„For children only – the search engine fragFINN“
Anke Meinders is the Managing Director of the NGO fragFINN e.V. and has been working as a media pedagogue for fragFINN e.V. since 2007. She studied education and has been interested in the relationship between education and digital media for children from the very beginning. Due to her many years of experience at fragFINN, she is very familiar with online content for the young target group. Keeping the search engine fragFINN interesting and attractive for children over time is a great and exciting task for fragFINN and the team.
In her talk Anke will introduce the concept and initial idea behind fragFINN, a website and an app offering children their own space in the Internet where they can surf, search and play safely. The fragFINN search engine is based on a so-called ‚positive list‘ of websites that are both interesting and safe for children. Anke will outline how the fragFinn search engine works and what the special needs of the target group of children are. Over the years fragFINN has developed steadily. Children’s surfing habits are also changing at a fast pace. Anke will report on these changes and the challenges for fragFINN in the case study. She will also explain how AI can support the testing of the websites and the quality of the search results in the future.
Viktor Lofgren
Founder, Marginalia Search
Industry Track “Alternative Search Engines”
| 5 October | 17.00 |
„Assumptions about the shape of the web“
Viktor Lofgren is the Founder of Marginalia Search, a small specialised search engine, based in Sweden. The search engine takes you of the beaten track by letting you find small quality web pages. These pages barely surface in commercial search engines because they are snowed under by larger commercial websites and search engine marketing.
