These terms refer to the two types of alert that you can set up in persistent chat to help you stay in touch with activity in the chat rooms you’re following:

Notification alerts are sent automatically by Lync to alert you to activity in any room(s) you’re following. By DEFAULT, these alerts follow the settings in the Persistent Chat Options window. You can change those settings, and you can also customize your notifications if you want more distinctive alerts.

Topic feeds are automatic alerts triggered, not by activity in a specific room, but by the appearance of WORDS or PHRASES that you’ve told Lync to look for in the posts of the chat rooms you follow. A topic feed listing will display the name of the person who posted the message, the time it was posted, and the text of the message containing the target TERM(s).
