Start by acknowledging the challenge of rare events and the need for short-term proxies. Then propose a set of leading indicators that are sensitive to changes in harmful content exposure and user behavior, explaining why each is chosen. Emphasize the importance of balancing speed with validity and avoiding metrics that are too noisy or lagging.
Pro tip: Focus on metrics that are directly tied to the moderation action, such as appeal rates or user reports, as they can signal false positives/negatives quickly. Also, consider guardrail metrics to ensure you're not harming overall engagement.
Explain that because harmful content is rare, traditional metrics like prevalence may not show detectable changes in short-term tests. Therefore, we need leading indicators that are more sensitive.
Propose metrics such as user reports of harmful content, appeal rates on moderated content, and user engagement metrics (e.g., likes, shares) on moderated items. These can reflect immediate reactions to moderation decisions.
For each metric, explain why it would change quickly if the moderation system is altered. For example, an increase in user reports might indicate more harmful content slipping through, while a spike in appeals might suggest over-moderation.
Mention the need to monitor overall platform health metrics like daily active users, session time, or overall engagement to ensure the moderation change doesn't have unintended negative consequences.
Acknowledge that short-term metrics are proxies and may not perfectly correlate with long-term harm reduction. Suggest validating with longer-term or offline metrics when possible.

Start by clarifying the chatbot's goal and the knowledge base's role, then propose an experiment design (e.g., A/B test) that isolates the knowledge base's impact. Define a metric framework covering quality, usefulness, and business outcomes, and explain how you'd validate and iterate.
Pro tip: Emphasize guardrail metrics (e.g., customer satisfaction, escalation rate) to ensure improvements don't harm user experience, and discuss how you'd handle novelty effects and long-term value.
Define the chatbot's purpose (e.g., resolve queries, reduce agent workload) and formulate testable hypotheses about how knowledge base changes affect outcomes.
Choose an A/B test with random assignment, ensuring control and treatment groups differ only in the knowledge base version. Consider sample size, duration, and potential confounders.
Define primary metrics (e.g., resolution rate, CSAT) and secondary metrics (e.g., response accuracy, containment rate). Include guardrail metrics like escalation rate and user effort.
Use statistical tests to compare groups, check for significance, and segment by user type or query category. Assess practical significance and potential biases.
Based on results, decide whether to roll out, refine, or abandon changes. Set up ongoing monitoring to detect degradation and ensure long-term value.
