DataExposer: Exposing Disconnect between Data and Systems
Sainyam Galhotra, Anna Fariha, Raoni Lourenço +3
As data is a central component of many modern systems, the cause of a system malfunction may reside in the data, and, specifically, particular properties of the data. For example,…
Stochastic Package Queries in Probabilistic Databases
Matteo Brucato, Nishant Yadav, Azza Abouzied +2
We provide methods for in-database support of decision making under uncertainty. Many important decision problems correspond to selecting a package (bag of tuples in a relational d…
Causality-Guided Adaptive Interventional Debugging
Anna Fariha, Suman Nath, Alexandra Meliou
Runtime nondeterminism is a fact of life in modern database applications. Previous research has shown that nondeterminism can cause applications to intermittently crash, become unr…
Conformance Constraint Discovery: Measuring Trust in Data-Driven Systems
Anna Fariha, Ashish Tiwari, Arjun Radhakrishna +2
The reliability and proper function of data-driven applications hinge on the data's continued conformance to the applications' initial design. When data deviates from this initial…
New Results for the Complexity of Resilience for Binary Conjunctive Queries with Self-Joins
Cibele Freire, Wolfgang Gatterbauer, Neil Immerman +1
The resilience of a Boolean query is the minimum number of tuples that need to be deleted from the input tables in order to make the query false. A solution to this problem immedia…
Example-Driven Query Intent Discovery: Abductive Reasoning using Semantic Similarity
Anna Fariha, Alexandra Meliou
Traditional relational data interfaces require precise structured queries over potentially complex schemas. These rigid data retrieval mechanisms pose hurdles for non-expert users,…
