Preface

This volume contains the papers of WOWS 2024, the first International Workshop
on Open Web Search, co-located with the 46th European Conference on Informa-
tion Retrieval (ECIR) in Glasgow, UK, on 28 March 2024.


WOWS 2024 had two calls for contributions. The first call targets scientific contri-
butions on cooperative search engine development. This includes cooperative
crawling of the web and cooperative deployment and evaluation of search en-
gines. We specifically highlight the potential of enabling public and commercial
organizations to use an indexed web crawl as a resource to create innovative
search engines tailored to specific user groups, instead of relying on one search
engine provider. The second call aims at gaining practical experience with joint,
cooperative evaluation of search engine prototypes and their components using
the Information Retrieval Experiment Platform TIREx.


The workshop involved a keynote by Negar Arabzadeh from the University of
Waterloo, 8 paper presentations (5 full papers and 3 short papers accepted out of
13 submissions), and a breakout session with participant discussions. WOWS
received funding from the European Union’s Horizon Europe research and
innovation program under grant agreement No 101070014 (OpenWebSearch.EU,
https://doi.org/10.3030/101070014). We would like to thank the Program
Committee members for helpful reviews and suggestions to improve the
contributions to the workshop. Special thanks go to Christine Plote, Managing
Director of the Open Search Foundation for the WOWS 2024 website at:
