Infinite Probabilistic Databases [PDF]
, 2020 Probabilistic databases (PDBs) are used to model uncertainty in data in a quantitative way. In the standard formal framework, PDBs are finite probability spaces over relational database instances.

From Causes for Database Queries to Repairs and Model-Based Diagnosis and Back [PDF]
, 2014 In this work we establish and investigate connections between causes for query answers in databases, database repairs wrt. denial constraints, and consistency-based diagnosis.

Dynamic Provenance for SPARQL Update [PDF]
, 2014 While the Semantic Web currently can exhibit provenance information by using the W3C PROV standards, there is a "missing link" in connecting PROV to storing and querying for dynamic changes to RDF graphs using SPARQL.

FASTAGEDS: Fast Approximate Graph Entity Dependency Discovery
, 2023 This paper studies the discovery of approximate rules in property graphs. We propose a semantically meaningful measure of error for mining graph entity dependencies (GEDs) at almost hold, to tolerate errors and inconsistencies that exist in real-world ...

Share the Tensor Tea: How Databases can Leverage the Machine Learning Ecosystem
, 2022 We demonstrate Tensor Query Processor (TQP): a query processor that automatically compiles relational operators into tensor programs. By leveraging tensor runtimes such as PyTorch, TQP is able to: (1) integrate with ML tools (e.g., Pandas for data ...
