ALLDATA 2021 - The Seventh International Conference on Big Data, Small Data, Linked Data and Open Data

April 18, 2021 - April 22, 2021

ALLDATA 2021: Program
Onsite and Online Options: In order to accommodate a large number of situations, we are offering the option for either physical presence or virtual participation (pdf slides or pre-recorded videos).

For 2021, all events will be held in a hybrid mode with five options: on site or virtual choices (live, prerecorded videos, voiced presentation slides, and .pdf slides).

We hope for better times allowing us to return to the traditional on site scientific events. However, we are ready to adapt any which way the conditions dictate. As an example, please see such a hybrid program from 2020: CYBER 2020 Program.
