What is comment sentiment analysis?

Sentiment tells you how people feel; intent tells you what they want. For lead generation the second question matters more — 'this looks expensive' and 'what does this cost' are both about price, but only one is a buying signal. Sentiment alone would treat them as the same negative-ish remark and file them together, which is how commercial questions end up sitting in the wrong queue. Put simply, sentiment is a content metric and intent is a revenue metric: a channel can look healthy in a sentiment dashboard while every buying question in it goes unanswered for a week, which is roughly how long it takes a prospect to shortlist someone else.
