Dear Experts, Supporters and Friends of Open Internet Search,
the current COVID-19 pandemic forces us once again to change the plans for the the 2nd international Open Search Symposium (OSSYM 2020) for this year: since we could have met with only a very small number of participants physically on site and CERN had to furthermore cancel all visits to the experimental sites for the rest of the year 2020, we decided to hold the 2nd Open Search Symposium as a pure online (web-based) event.
As you know the pandemic has tremendously boosted digital activities of individuals, society and economy as a whole. This continues to underpin how important it is to ensure that orientation in the digital sphere, as well as the access to digital knowledge, information and services via the internet remains neutral, open, democratic and in a privacy respecting way.
On 12-14 October the 2nd international Open Search Symposium (OSSYM 2020) will be held as a fully web-based, remote event, hosted by CERN. This event will allow us to dive even deeper into the societal, scientific and technical aspects of open and distributed internet search.
You are kindly invited to join this meeting, the networking activities and discussions online. More details and the relevant web links can be found below. The call for contributions has already been closed and we thank all the authors for their very interesting contributions! The OSSYM scientific program is now available online we are looking forward to interesting presentations and discussions as well as to expand the network and cooperation among research groups and experts in the context of Open Search during the symposium in October.
As you know, the development of a European Open Internet search community and infrastructure involves expertise from many different scientific and technical fields. It requires profound understanding of internet search technologies and new thinking for services and innovative applications, to be built on an open and distributed Internet search infrastructure in and for Europe.
Please register for OSSYM 2020 via the link below – and see you online in October!
Please pass on the message and inform your colleagues and peers about the upcoming OSSYM 2020. For any suggestions and further ideas for OSSYM 2020 please contact us at
