I will be giving an invited talk at the #ecir2026 IR4Good track about #openwebsearcheu: "Towards a shared infrastructure for assembling web search engines"

https://djoerdhiemstra.com/2026/towards-a-shared-infrastructure-for-assembling-web-search-engines/
Towards a shared infrastructure for assembling web search engines
Web search engines are essential for navigating the web. Suppose we look at the web as a service that is provided by public utility companies, a service similar to electricity, water or telephone. To make sure that everyone has access to the web, public utility companies have to be subject to public control and regulation. Without regulation, a single firm may abuse their natural monopoly, for instance by raising prices, by deteriorating the service, by delivering unequal quality to different groups, or by pushing advertisements and propaganda. Equity requires that all citizens can access the web at a fair price, and at a sufficient level of quality, via transparent, well-regulated, community-based or government-based control. OpenWebSearch.eu is a European Union funded project that researches what a transparent, well-regulated, community-based web search engine would look like. The project builds the index for a web search engine on open infrastructure that is distributed over four data centers in four different European countries. The data centers cooperatively crawl the web, cooperatively preprocess and enrich the web data, and cooperatively build an inverted index that is shared with the world. We envision a future where a search engine is “assembled” from parts provided by many different companies, based on public standards. I will discuss public standards for search engine indexes, such as the common index file format (CIFF) and approaches based on open data formats like Parquet and open cloud object storage like S3. Furthermore, I will show how researchers can query the Open Web Index remotely using a low-cost local machine, without the need to download the full index, even though it currently consists of more than 10 billion web pages. _To be presented at the European Conference on Information Retrieval (ECIR 2026)IR 4Good track on 30 March 2026 in Delft, the Netherlands_

looking forward to visiting my alma mater, @djoerd and talk about indexing the #chemistry on the web and what role @openwebsearcheu could play here: "Search engines and finding the long tail of science: is Bioschemas the solution?"

🔎 The #OpenWebSearchEU project, coordinated by @mgrani.bsky.social and #OpenSearch Foundation, aims to strengthen Europe's digital sovereignty. With the launch of the #OpenWebIndex (OWI), it has reached a milestone for open internet search:

A European Web Data Infrastructure will offer large-scale access to Web data for all European companies, SMEs and innovators. The proof of concept is already available. #openwebsearcheu

@heiseonline Nur nutzt man damn halt immer noch besagte US-Dienste, nur eben mit einem Scraping-Dienst dazwischen. Mit @MetaGer wird zwar nicht gescrapt, aber wir brauchen echte EU-basierte Alternativen wie @openwebsearcheu und bald @nolm.
Und ja, das ist Eigenwerbung, aber ich mache den Kram ja […]

@egonw We do that in @openwebsearcheu! We are already parsing schema.org, mostly for locations. I don't know how much work it would be to do this for bioschemas too (and to crawl those sites). If you DM me your email address, I can get you in contact with my colleagues to find out.

Sounds like everyone agrees that "an open European search index would be nice" (hello @openwebsearcheu 👋) but of course the Commission's DMA enforcement official in the room cannot say anything about that; more EU funding for the #digitalcommons is a political decision which requires support […]

Apparently @openwebsearcheu does not obey robots.txt. That's not a good way to start a project.

@djoerd @openwebsearcheu it should not be a lot of work. I have been doing this for various schema.org types for some time, but do not have the scalability. I'll DM
