Change Analysis flags the events worth investigating
Every analysis cycle now runs a change-analysis pass and writes the results back as queryable insights against your dataset, categories, subcategories, and individual topics. You no longer have to spot shifts yourself by scrubbing through charts. The interesting moments come to you.
What it detects
Four families of event, each with a significance score so only the ones that actually matter surface in the UI:
- Step changes in volume. Step-ups and step-downs in how often a topic or category is being mentioned, with the date of the change marked on the trend chart.
- Emerging themes. Topics that are new or newly active in this analysis window compared to the previous one.
- Concentration shifts. When mentions of a topic cluster more tightly, or spread out, across the dataset.
- Distribution shifts. When the mix changes across sources, sentiment, or sub-issues for a given category.
Where you see it
The events show up wherever you’re already looking. On trend charts they appear as dated annotations on the line, with the full period range in the tooltip. On insight detail pages, the right rail lists the recent changes for that topic. At the dataset level, the hero of an overview now leads with sentiment and the topic trends that have moved the most.
Runs on the first batch too
Previously change analysis only ran on incremental refreshes, which meant the first time you loaded a dataset you saw none of it. It now spawns automatically on initial-batch ingestion, so newly imported datasets land with the full set of detected events already in place.
