What does that tell us? That at least 86 people were put off booking the hotel by a negative review (would you vote a negative review helpful and then book)?
Of course, it's much more than 'just' 86*, because very few potential guests bother to vote 'helpful' when viewing TripAdvisor reviews - so it is essential that hotels take all the action they can to minimise these negatives.
To see how effective Dialogue is, have a look at the last two paragraphs of this post; negatives posted about this client have been reduced by over half in just two months.
At the risk of stating the obvious: if your guests' negative opinions are managed in private, they can't possibly put an potential guest off booking. And, on top of that, your ranking on TripAdvisor will rise.
*Needless to say, it's not just the people who are voting negative reviews 'helpful' who are being put off booking, but potentially anyone who reads them. We have lots of anecdotal evidence (from TripAdvisor) about the number of people who read a review compared with those who vote - in one such case there are 6 'helpful' votes where 425 people have read the review; that's 70 people 'reading' for every one who voted.
