A Unified Approach for Resilience and Causal Responsibility with Integer Linear Programming (ILP) and LP Relaxations
Neha Makhija, Wolfgang Gatterbauer
Resilience is one of the key algorithmic problems underlying various forms of reverse data management (such as view maintenance, deletion propagation, and various interventions for…
SANTOS: Relationship-based Semantic Table Union Search
Aamod Khatiwada, Grace Fan, Roee Shraga +4
Existing techniques for unionable table search define unionability using metadata (tables must have the same or similar schemas) or column-based metrics (for example, the values in…
Principles of Query Visualization
Wolfgang Gatterbauer, Cody Dunne, H. V. Jagadish +1
Query Visualization (QV) is the problem of transforming a given query into a graphical representation that helps humans understand its meaning. This task is notably different from…
Any-k Algorithms for Enumerating Ranked Answers to Conjunctive Queries
Nikolaos Tziavelis, Wolfgang Gatterbauer, Mirek Riedewald
We study ranked enumeration for Conjunctive Queries (CQs) where the answers are ordered by a given ranking function (e.g., an ORDER BY clause in SQL). We develop "any-k" algorithms…
Relational Diagrams: a pattern-preserving diagrammatic representation of non-disjunctive Relational Queries
Wolfgang Gatterbauer, Cody Dunne, Mirek Riedewald
Analyzing relational languages by their logical expressiveness is well understood. Something not well understood or even formalized is the vague concept of relational query pattern…
