Personalized Environment for Querying Semantic Knowledge Graphs: a MapReduce Solution

Abstract : Querying according to a personalised context is an increasingly required feature on semantic graph databases. We define contexts by using constraints imposed on queries and not on data sources. No correction trial is performed on an inconsistent database but answers are ensured to be valid. Data confidence according to provenance is also taken into account. As constraint validation and query evaluation are two independent modules, our approach can be tested with di↵erent query evaluators. This paper focus on a MapReduce query environment.
