Nikolaus Augsten on sabbatical leave until September 2022
Nikolaus Augsten is on sabbatical leave until September 2022. During this time, Martin Schäler leads the Database Group including all associated facilities.
Paper at SIGMOD 2022
Our paper on similarity queries for JSON documents with the title "JEDI: These aren't the JSON documents you're looking for..." has been accepted at the ACM International Conference on Management of Data (SIGMOD) 2022.

Paper at HardBD (ICDE Workshop) and DASFAA
Our co-authored paper "An Investigation of Atomic Synchronization for Sort-Based Group-By Aggregation on GPUs" got accepted at the Joint International Workshop on Big Data Management on Emerging Hardware and Data Management on Virtualized Active Systems (HardBD@ICDE2021). The paper investigates how to minimize the synchronization overhead for efficient sort-based group-by-aggregate computations on GPUs.
Our co-authored paper "Accurate Cardinality Estimation of Co-occurring Words Using Suffix Trees" got accepted at the International Conference on Database Systems for Advanced Applications (DASFAA) 2021. The paper allows accurate and fast estimation the expected frequencies of arbitrary word groups using suffix trees relevant e.g., for sophisticated physical relational operator selection.
An article in Süddeutsche Zeitung refers to the work of one of our group members
The research of our colleague Martin Schäler in the ESQUIRE project on privacy-preserving data analysis was mentioned in
news paper article
in Süddeutsche Zeitung.
The work was done when he was still at the Karlsruhe Institute of Technology (Karlsruhe, Germany) shortly before joining the Database Group in Salzburg.

Paper at BMC Bioinformatics
In an interdisciplinary project with the Department of Biosciences we have developed DeSignate, a tool for the identification of molecular characters for taxon diagnoses. DeSignate is freely available as a web application
and open source
. The resulting paper
was recently published in the BMC Bioinformatics Journal.
