It isn't that easy to reverse engineer our models. We test our models for a certain degree of robustness (same concepts expressed in different ways will be generally picked up). Plus, if companies go out of their way to express risks in cryptic terms, our models picks up needlessly convoluted text as well. We also constantly retrain our models so I don't foresee this becoming a problem in the foreseeable future.
Thanks! Earnings transcripts sentiment analysis is not currently in our product roadmap. One of the reasons is that such tools are already available on the market. We wanted to explore more underutilized sources of information.
