Bias in OLAP Queries: Detection, Explanation, and Removal [PDF]
arXiv, 2018 On line analytical processing (OLAP) is an essential element of decision-support systems. OLAP tools provide insights and understanding needed for improved decision making. However, the answers to OLAP queries can be biased and lead to perplexing and incorrect insights.

Algèbre OLAP et langage graphique [PDF]
Congr\`es Informatique des Organisations et Syst\`emes
d'Information et de D\'ecision - INFORSID'06, Hammamet : Tunisie (2006), 2010 This article deals with OLAP systems based on multidimensional model. The conceptual model we provide, represents data through a constellation (multi-facts) composed of several multi-hierarchy dimensions. In this model, data are displayed through multidimensional tables. We define a query algebra handling these tables.
