Output-Sensitive Evaluation of Acyclic Conjunctive Regular Path Queries
Mahmoud Abo Khamis, Alexandru-Mihai Hurjui, Ahmet Kara +3
Conjunctive Regular Path Queries, or CRPQs for short, are an essential construct in graph query languages. In this paper, we propose the first output-sensitive algorithm for evalua…
Advancing Fact Attribution for Query Answering: Aggregate Queries and Novel Algorithms
Omer Abramovich, Daniel Deutch, Nave Frost +2
In this paper, we introduce a novel approach to computing the contribution of input tuples to the result of the query, quantified by the Banzhaf and Shapley values. In contrast to…
Output-Sensitive Evaluation of Regular Path Queries
Mahmoud Abo Khamis, Ahmet Kara, Dan Olteanu +1
We study the classical evaluation problem for regular path queries: Given an edge-labeled graph and a regular path query, compute the set of pairs of vertices that are connected by…
