Have you ever tried to analyze the sentiment of a long-form document like a financial report, technical whitepaper or regulatory filing? You probably noticed that the sentiment score often feels way off. That’s because most sentiment analysis tools return a single, aggregated sentiment score—usually positive, negative, or neutral—for the entire document. This approach completely misses the complexity and nuance embedded in long-form content.
I encountered this challenge while analyzing annual reports in the finance industry. These documents are rarely uniform in tone. The CEO’s message may sound upbeat, while the “Risk Factors” section could be steeped in caution. A single sentiment score doesn’t do justice to this mix.
