Provenance

IEEE Security & Privacy, 2016
Collecting and processing provenance, i.e., information describing the production process of some end product, is important in various applications, e.g., to assess quality, to ensure reproducibility, or to reinforce trust in the end product. In the past, different types of provenance meta-data have been proposed, each with a different scope. The first

Provenance semirings

Proceedings of the twenty-sixth ACM SIGMOD-SIGACT-SIGART symposium on Principles of database systems, 2007
We show that relational algebra calculations for incomplete databases, probabilistic databases, bag semantics and why-provenance are particular cases of the same general algorithms involving semirings. This further suggests a comprehensive provenance representation that uses semirings of polynomials.

On provenance and privacy

Proceedings of the 14th International Conference on Database Theory, 2011
Provenance in scientific workflows is a double-edged sword. On the one hand, recording information about the module executions used to produce a data item, as well as the parameter settings and intermediate data items passed between module executions, enables transparency and reproducibility of results.

Data Provenance

Foundations and Trends in Databases, 2021
Data provenance has evolved from a niche topic to a mainstream area of research in databases and other research communities. This article gives a comprehensive introduction to data provenance. The main focus is on provenance in the context of databases.

The Provenance of WINE

2012 Ninth European Dependable Computing Conference, 2012
The results of cyber security experiments are often impossible to reproduce, owing to the lack of adequate descriptions of the data collection and experimental processes. Such provenance information is difficult to record consistently when collecting data from distributed sensors and when sharing raw data among research groups with variable standards ...

Computational Provenance

Computing in Science & Engineering, 2008
Systematic mechanisms for capturing and exploring lineage information of digital artifacts are at the heart of a new field of research called computational provenance. This special issue aims to raise awareness and contribute to a better understanding of the issues surrounding computational provenance to the broader CiSE community.
