Metadata as Support for Data Provenance

2017
Provenance tackles problems as: provides information to a user about his data that are given to him or passed by him; informs a user in which way a foreign user has used his data; allows rollback mechanisms on wrong data; observes the currentness of data for closed contracts and creates a history of data for a user.

Empowering Provenance in Data Integration

2009
The provenance of data has recently been recognized as central to the trust one places in data. This paper presents a novel framework in order to empower provenance in a mediator based data integration system. We use a simple mapping language for mapping schema constructs, between an ontology and relational sources, capable to carry provenance ...

Provenance Management for Data Exploration

2010
Computing has been an enormous accelerator to science and industry alike and it has led to an information explosion in many different fields. The unprecedented volume of data acquired by sensors, derived by simulations and analysis processes, and shared on the Web opens up new opportunities, but it also creates many challenges when it comes to managing

Provenance in Linked Data Integration. [PDF]

, 2010
The open world of the (Semantic) Web is a global information space offering diverse materials of disparate qualities, and the opportunity to re-use, aggregate, and integrate these materials in novel ways. The advent of Linked Data brings the potential to expose data on the Web, creating new challenges for data consumers who want to integrate these data.

Provenance for Web 2.0 Data

2012
In this paper, we look at Web data that comes from multiple sources, as in the Web 2.0. We argue that Web data is more than just its content. Rather, a piece of Web data carries along different facets, such the transformations that data underwent, the different perspectives that users have on the content, and the context in which a statement is made ...

Provenance in a Modifiable Data Set

2013
Provenance of data is now widely recognized as being of great importance, thanks in large part to pioneering work [4, 6] by Peter Buneman and his collaborators in a stream that continues to produce influential papers today [1-3, 7]. When we consume data from a database, we often care about where these data come from, how they were derived, and so forth.

On Provenance of Data Fusion Queries.

2011
Data Lineage is an open research problem. This is particularly true in data integration systems, where information coming from different sources, potentially uncertain or even inconsistent with each other, is integrated. In this context, having the possibility to trace the lineage of certain data can help unraveling possible unexpected or questionable ...
