Invisible Search in Everyday Life

How can we understand search and search engines in everyday life? In his lecture Sundin will introduce and discuss some key concepts from his  new book Invisible Search and Online Search Engines: The Ubiquity of Search in Everyday Life (2019, with Jutta Haider); specifically he will elucidate the notions friction of relevance and infrastructural meaning-making. The lecture broadens a traditional understanding of searching in information science by locating searching squarely in society and as entwined with the conditions of everyday life.

A call for fair search engines

Search engines like Google have a massive influence on what information users get to see, and on what search results users select. It has been often lamented that search engines are biased. I, however, argue that we have only scratched the surface because search engine bias is a multifaceted concept and the discussion usually solely focuses on some aspects. Further to giving an overview of the topic, I will show how search engine providers (and regulators) can take steps towards making search fair. Whereas a bias-free search engine is impossible, a fair search is. Here, I will not only focus on the big web search engines but also on how developers and product owners can make their search systems fair.

Product Search at

OTTO is one of the largest full-range online retailer in Germany with over 2.9 million products. Thus the internal on-site product search with more than 1 million search queries per day is the most critical feature to make relevant products and information easy to find. Achieving the right balance between business, measuring search quality and user needs can be quite challenging when building an ecommerce search engine. How we at OTTO respond to these challenges will be part of this talk.

Data Science in Search Engine Development

Machine Learning has been an essential part of large-scale search engine development even before the term "data science" was coined. With the increasing interest in data science and artificial intelligence, the impact of self-learning algorithms on search engine development, relevance and transparency has to be reviewed. In addition, what is the chance for new search engines to succeed without the vast amount of data that has already been collected?
