Constant-Delay Enumeration for Nondeterministic Document Spanners
Antoine Amarilli, Pierre Bourhis, Stefan Mengel +1
We consider the information extraction framework known as document spanners, and study the problem of efficiently computing the results of the extraction from an input document, wh…
Enumeration on Trees with Tractable Combined Complexity and Efficient Updates
Antoine Amarilli, Pierre Bourhis, Stefan Mengel +1
We give an algorithm to enumerate the results on trees of monadic second-order (MSO) queries represented by nondeterministic tree automata. After linear time preprocessing (in the…
Enumeration on Trees under Relabelings
Antoine Amarilli, Pierre Bourhis, Stefan Mengel
We study how to evaluate MSO queries with free variables on trees, within the framework of enumeration algorithms. Previous work has shown how to enumerate answers with linear-time…
Counting Answers to Existential Positive Queries: A Complexity Classification
Hubie Chen, Stefan Mengel
Existential positive formulas form a fragment of first-order logic that includes and is semantically equivalent to unions of conjunctive queries, one of the most important and well…
