#UBODIn will be at #NEDB_Day_2026 on Jan 16 with two posters!

"Flow-centric Query Evaluation Pipelines" (Victoria, Andrew, Krishna) presents our preliminary efforts to make a scheduler-friendly query evaluation pipeline for our #Draupnir datalog engine. The key insight behind our work is decoupling state from operators. By making operators (mostly) stateless, we can inline better, and we can expose IO to the scheduler more efficiently.

"Benchmarking Tabular Representation Models on Longitudinal Data" (Pratik) presents our work on data integration for longitudinal studies. Longitudinal studies generate a slew of datasets that are almost alike, but not quite. Coupled with the fact that attributes are identified by prose questions rather than simple identifiers, they aren't a great fit for existing data integration/unionability tools. We'll specifically be presenting a benchmark, painstakingly adapted from the American National Election Survey, which shows that we need new data integration tools.

Delayed due to lack of picture, but it was *really* great to catch up with past #UBDB (pre-#UBDBPL) grads in the bay area last month. My PhD student @amazing_ying , MS thesis student Gourab, and Varsha and Harsh: 2/4 of best 5/662 team I've ever taught. (and Zhen too!)

😄

Alright... I've been putting this nonsense off for long enough. With much fanfare 🎉, the massive frontend rework that started on Amtrak's Empire Builder back in Summer '21, is now ready for public consumption.

Our workflow-style notebook #Vizier is officially 2.0 🎂.

Get it while it's hot: https://github.com/VizierDB/vizier-scala/releases/tag/v2.0.1

'Grats to Pratik and Juseung on their #HILDA2024 accept for "Drag, Drop, Merge: A Tool for Streamlining Integration of Longitudinal Survey Instruments", which explores schema integration in longitudinal studies, specifically in survey data with minor, yearly edits to the survey that accumulate over decades.

It is *really* fun to have a paper resulting from a hugely interdisciplinary collaboration between CS, Linguistics, Medicine, Stats (and soon-to-be Environmental Health).
