Generative Benchmark Creation for Table Union Search
Koyena Pal, Aamod Khatiwada, Roee Shraga +1
Data management has traditionally relied on synthetic data generators to generate structured benchmarks, like the TPC suite, where we can control important parameters like data siz…
DIALITE: Discover, Align and Integrate Open Data Tables
Aamod Khatiwada, Roee Shraga, Renée J. Miller
We demonstrate a novel table discovery pipeline called DIALITE that allows users to discover, integrate and analyze open data tables. DIALITE has three main stages. First, it allow…
Explaining Dataset Changes for Semantic Data Versioning with Explain-Da-V (Technical Report)
Roee Shraga, Renée J. Miller
In multi-user environments in which data science and analysis is collaborative, multiple versions of the same datasets are generated. While managing and storing data versions has r…
Semantics-aware Dataset Discovery from Data Lakes with Contextualized Column-based Representation Learning
Grace Fan, Jin Wang, Yuliang Li +2
Dataset discovery from data lakes is essential in many real application scenarios. In this paper, we propose Starmie, an end-to-end framework for dataset discovery from data lakes…
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…
DomainNet: Homograph Detection for Data Lake Disambiguation
Aristotelis Leventidis, Laura Di Rocco, Wolfgang Gatterbauer +2
Modern data lakes are deeply heterogeneous in the vocabulary that is used to describe data. We study a problem of disambiguation in data lakes: how can we determine if a data value…
