Sharepoint automatic suggestions for "topics of interest"

Hi all,

Recently a sharepoint page on which we were posting started auto-highlighting some words, marking them as "relevant" and making them clickable.

The highlight can be turned off after clicking  "No" in the following prompt, however after refreshing the page the word becomes highlighted again.

Is there a way to turn this off?

Will be grateful for any tips/help.

Thanks

S.
