The Second International Workshop on Open Web Search (WOWS) aims to promote and discuss ideas and approaches to open up the web search ecosystem so that small research groups and young startups can leverage the web to foster an open and diverse search market.

Therefore, the workshop, which takes place at ECIR2025, has two calls that support collaborative and open web search engines: (1) for scientific contributions, and (2) for participation in the WOWS-Eval shared task for collaborative evaluations of the Open Web Index.

The first call aims for scientific contributions to building collaborative search engines, including collaborative crawling, collaborative search engine deployment, collaborative search engine evaluation, and collaborative use of the web as a resource for researchers and innovators.

Submission Guidelines

Submissions to WOWS should be 5 to 12 pages. Reviewing will be single-blind. Please, use the single-column CEUR-WS format available at http://ceur-ws.org/Vol-XXX/CEURART.zip
