Quantifying the inconsistency of a database is motivated by various goals including reliability estimation for new datasets and progress indication in data cleaning. Another goal is to attribute to individual tuples a level of responsibility to the overall inconsistency, and thereby prioritize&nbsp;[&hellip;]

Uniform Reliability of Self-Join-Free Conjunctive Queries

Antoine Amarilli ; Benny Kimelfeld.

The reliability of a Boolean Conjunctive Query (CQ) over a tuple-independent probabilistic database is the probability that the CQ is satisfied when the tuples of the database are sampled one by one, independently, with their associated probability. For queries without self-joins (repeated relation&nbsp;[&hellip;]

Weight Annotation in Information Extraction

Johannes Doleschal ; Benny Kimelfeld ; Wim Martens ; Liat Peterfreund.

The framework of document spanners abstracts the task of information extraction from text as a function that maps every document (a string) into a relation over the document's spans (intervals identified by their start and end indices). For instance, the regular spanners are the closure under the&nbsp;[&hellip;]
