Dear Experts, Supporters and Friends of Open Internet Search,
due to the current COVID-19 pandemic, we needed to rearrange the plans for the the 2nd international Open Search Symposium (OSSYM 2020) and meetings on Open Search this year. The pandemic has tremendously boosted the digital and digital activities of individuals, society and economy as a whole. This underpins impressively 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. Thus, we are very pleased to invite you to the following to events on Open Internet Search:
12-14 October the 2nd international Open Search Symposium (OSSYM 2020) will be 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 these meetings and contributed to the scientific programme, networking activities and discussions. More details and the relevant web links can be found below. Both events will provide us with inspiring opportunities to expand the network and cooperation already initiated among research groups and experts in the context of Open Search.
As you know, the development of an European Open Internet search community and infrastructure involved expertise from many 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.
We are calling for your active participation in the Open Search Symposium 2020 in various formats: with scientific papers, sharing of practical experiences or by introducing concepts and positions during presentations and in the different interactive sessions.
Please pass on the message and inform your colleagues and peers about the upcoming events. For any suggestions and further ideas for OSSYM 2020 please contact us at
On behalf of the symposium/organizing committee,
Dr. Andreas Wagner, CERN
Prof. Dr. Christian Guetl , TU Graz
Prof. Dr. Michael Granitzer, Univ. Passau
Dr. Stefan Voigt, open search foundation
Preparatory Web meeting
As part of the Open Search Symposium (OSSYM) series the web meeting provided a forum to discuss and advance the ideas and concepts of Open Internet search in Europe. The web meeting allowed interested parties to come together for a couple of hours to listen to share keynotes and perspectives on Open Internet Search and discuss and prepare ideas for the Open Search Symposium to be hosted at CERN in October.
