The article “Active querying approach to epidemic source detection on contact networks” has been published in Nature Scientific Reports by DDIS alumni Dr. Martin Sterchi in collaboration with Lorenz Hilfiker, Rolf Grütter & Abraham Bernstein! The paper’s problem of interest is the identification of an epidemic’s patient zero given a network of contacts and a set of infected […]

During May of this year, The Web Conference 2019 took place in San Francisco. Bibek Paudel, recent graduate of DDIS, was there to present a paper and poster titled ‘Iterative Learning Embeddings and Rules for Knowledge Graphs’. This paper was created in collaboration with —among others— visiting scholar Wen Zhang. We congratulate them on their […]

The paper “Machines Tuning Machines: Configuring Distributed Stream Processors with Bayesian Optimization” by Lorenz Fischer, Shen Gao, and Abraham Bernstein was accepted at the IEEE Cluster 2015 conference. The paper presents an approach based on bayesian optimization that automatically tunes the myriad of parameters that a distributed stream processing system exposes. The paper will soon […]

On June 13 Cosmin Basca successfully defended his thesis “Federated SPARQL Query Processing. Reconciling Diversity, Flexibility and Performance on the Web of Data”. In his thesis Cosmin explores new, highly-efficient approaches for federated SPARQL querying. In particular Cosmin presents the Avalanche federated query processor. A Clearly relaxed Cosmin after the defense…

Freshly minted PhD Philip Stutz and DDIS student Bibek Paudel successfully presented TripleRush — a paper co-authored with Ela Verman and Abraham Bernstein — at the World Wide Web Conference in Florence. TripleRush is a highly parallelized and distributed in-memory graph database (or triple store) that performs better than its competitors. It also has the special feature of […]
