• Looking at the timing, I'm thinking there might have been a recent update or change. Has there been any significant product update or system change in the past 1-2 months?

Why it matters: Recent changes often correlate with performance shifts. Expected answer: Yes, there was a minor update to the NLP model. Impact on approach: If confirmed, we'd focus on the update's impact and potential rollback.

• Considering the scale of the drop, I'm wondering about data quality. Have there been any changes in the data sources or data collection methods recently?

Why it matters: Data quality directly impacts sentiment analysis accuracy. Expected answer: No significant changes in data sources or collection methods. Impact on approach: If unchanged, we'd look more closely at model performance and potential data drift.

• Given the nature of sentiment analysis, I'm curious about language coverage. Has there been any expansion or change in the languages supported by U-Analyze?

Why it matters: Language expansion could introduce new challenges in sentiment detection. Expected answer: Yes, we recently added support for two new languages. Impact on approach: If confirmed, we'd investigate the performance across different languages.

• Thinking about external factors, have there been any significant world events or social media trends that could have shifted the overall sentiment landscape?

Why it matters: External events can dramatically alter sentiment patterns. Expected answer: No major events, but there's been an uptick in sarcasm and irony in social media. Impact on approach: If confirmed, we'd look into improving detection of complex sentiment expressions.
