Railgun: managing large streaming windows under MAD requirements [article]

Ana Sofia Gomes, João Oliveirinha, Pedro Cardoso, Pedro Bizarro
2021 arXiv   pre-print
Some mission critical systems, e.g., fraud detection, require accurate, real-time metrics over long time sliding windows on applications that demand high throughput and low latencies.  ...  As these applications need to run 'forever' and cope with large, spiky data loads, they further require to be run in a distributed setting.  ...  The Data Systems Research, CIDR 2009, Asilomar, CA, USA, January 4-7, 2009, Online Design of the Borealis Stream Processing Engine.  ...

Dennis Przytarski, Christoph Stach, Clémentine Gritti, Bernhard Mitschang
2021 Future Internet  
When, in 2008, Satoshi Nakamoto envisioned the first distributed database management system that relied on cryptographically secured chain of blocks to store data in an immutable and tamper-resistant manner  ...  As a result, we identify future research challenges with regard to query processing in blockchain systems.  ...  In Proceedings of the 9th Biennial Conference on Innovative Data Systems Research, CIDR ’19, Asilomar, CA, USA, 13–16 January 2019; pp. 111:1–111:9. 106.

An ASP-based Approach to Answering Natural Language Questions for Texts [article]

Dhruva Pendharkar, Kinjal Basu, Farhad Shakerin, Gopal Gupta
2021 arXiv   pre-print
CASPR can be regarded as a system that answers questions by "understanding" the text and has been tested on the SQuAD data set, with promising results.  ...  An approach based on answer set programming (ASP) is proposed in this paper for representing knowledge generated from natural language texts.  ...  In CIDR 2015, Seventh Biennial Conference on Innovative Data Systems Research, Asilomar, CA, USA, January 4-7, 2015, Online Proceedings.
