Sonar-TS: Search-Then-Verify Natural Language Querying for Time Series Databases
Researchers have introduced Sonar-TS, a new framework designed to improve natural language querying for time series databases. This neuro-symbolic approach uses a Search-Then-Verify pipeline, first employing a feature index to identify candidate data windows via SQL, and then using generated Python programs to confirm these candidates against raw signals. To facilitate evaluation, the team also developed NLQTSBench, a novel benchmark for assessing natural language queries on large-scale time series data. AI
