RAGE Against the Machine: Retrieval-Augmented LLM Explanations
Joel Rorseth, Parke Godfrey, Lukasz Golab +2
This paper demonstrates RAGE, an interactive tool for explaining Large Language Models (LLMs) augmented with retrieval capabilities; i.e., able to query external sources and pull r…
CREDENCE: Counterfactual Explanations for Document Ranking
Joel Rorseth, Parke Godfrey, Lukasz Golab +3
Towards better explainability in the field of information retrieval, we present CREDENCE, an interactive tool capable of generating counterfactual explanations for document rankers…
Discovery and Contextual Data Cleaning with Ontology Functional Dependencies
Zheng Zheng, Longtao Zheng, Morteza Alipour Langouri +3
Functional Dependencies (FDs) define attribute relationships based on syntactic equality, and, when usedin data cleaning, they erroneously label syntactically different but semanti…
Efficient Discovery of Approximate Order Dependencies
Reza Karegar, Parke Godfrey, Lukasz Golab +3
Order dependencies (ODs) capture relationships between ordered domains of attributes. Approximate ODs (AODs) capture such relationships even when there exist exceptions in the data…
Joint Variational Autoencoders for Recommendation with Implicit Feedback
Bahare Askari, Jaroslaw Szlichta, Amirali Salehi-Abari
Variational Autoencoders (VAEs) have recently shown promising performance in collaborative filtering with implicit feedback. These existing recommendation models learn user represe…
Discovering Domain Orders through Order Dependencies
Reza Karegar, Melicaalsadat Mirsafian, Parke Godfrey +4
Much real-world data come with explicitly defined domain orders; e.g., lexicographic order for strings, numeric for integers, and chronological for time. Our goal is to discover im…
Errata Note: Discovering Order Dependencies through Order Compatibility
Parke Godfrey, Lukasz Golab, Mehdi Kargar +2
A number of extensions to the classical notion of functional dependencies have been proposed to express and enforce application semantics. One of these extensions is that of order…
ABC of Order Dependencies
Pei Li, Michael Bohlen, Jaroslaw Szlichta +1
We enhance constrained-based data quality with approximate band conditional order dependencies (abcODs). Band ODs model the semantics of attributes that are monotonically related w…
Guided Automated Learning for query workload re-Optimization
Guilherme Damasio, Vincent Corvinelli, Parke Godfrey +4
Query optimization is a hallmark of database systems enabling complex SQL queries of today's applications to be run efficiently. The query optimizer often fails to find the best pl…
Authority-based Team Discovery in Social Networks
Morteza Zihayat, Aijun An, Lukasz Golab +2
Given a social network of experts, we address the problem of discovering a team of experts that collectively holds a set of skills required to complete a given project. Most prior…
Efficient Discovery of Ontology Functional Dependencies
Sridevi Baskaran, Alexander Keller, Fei Chiang +2
Poor data quality has become a pervasive issue due to the increasing complexity and size of modern datasets. Constraint based data cleaning techniques rely on integrity constraints…
Effective and Complete Discovery of Order Dependencies via Set-based Axiomatization
Jaroslaw Szlichta, Parke Godfrey, Lukasz Golab +2
Integrity constraints (ICs) provide a valuable tool for expressing and enforcing application semantics. However, formulating constraints manually requires domain expertise, is pron…
Effective Keyword Search in Graphs
Mehdi Kargar, Lukasz Golab, Jaroslaw Szlichta
In a node-labeled graph, keyword search finds subtrees of the graph whose nodes contain all of the query keywords. This provides a way to query graph databases that neither require…
OptImatch: Semantic Web System with Knowledge Base for Query Performance Problem Determination
Guilherme Damasio, Piotr Mierzejewski, Jaroslaw Szlichta +1
Database query performance problem determination is often performed by analyzing query execution plans (QEPs) in addition to other performance data. As the query workloads that org…
Fundamentals of Order Dependencies
Jaroslaw Szlichta, Parke Godfrey, Jarek Gryz
Dependencies have played a significant role in database design for many years. They have also been shown to be useful in query optimization. In this paper, we discuss dependencies…
