Your question is Evaluating Unstructured Data for Alpha. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How do you evaluate the alpha-generating potential of a new, unstructured data set?
Explain the practical process from data quality assessment and feature construction through signal validation, backtesting, and production monitoring. Address how you would avoid look-ahead bias, survivorship bias, data leakage, overfitting, and false discoveries when the data set may contain many possible signals.
Keep the answer focused on a research workflow for systematic investment analysis.
