First-Order Provenance Games [PDF]
, 2013 We propose a new model of provenance, based on a game-theoretic approach to query evaluation. First, we study games G in their own right, and ask how to explain that a position x in G is won, lost, or drawn.

Provenance for Aggregate Queries [PDF]
, 2011 We study in this paper provenance information for queries with aggregation. Provenance information was studied in the context of various query languages that do not allow for aggregation, and recent work has suggested to capture provenance by annotating ...

Provenance Circuits for Trees and Treelike Instances (Extended Version) [PDF]
, 2015 Query evaluation in monadic second-order logic (MSO) is tractable on trees and treelike instances, even though it is hard for arbitrary instances. This tractability result has been extended to several tasks related to query evaluation, such as counting ...

A Provenance Tracking Model for Data Updates [PDF]
, 2012 For data-centric systems, provenance tracking is particularly important when the system is open and decentralised, such as the Web of Linked Data. In this paper, a concise but expressive calculus which models data updates is presented.
