Probably. Looking at this page for an example…

<div id="othertags">

Tags:

<ul id="yourtaglist">

<li id="tag-87_349081"><a href="https://bbpress.org/forums/tags/tag" rel="tag">tag</a> </li>

</ul>

</div>

349081 is the user ID of whomever made the tag

tag-87 is the tag ID of the tag (which in this case is ‘tag’)

Now you can go to https://bbpress.org/forums/profile/349081 and easily see who that is so you can probably use get_username(349081) or something to get the name for a mouse over. I don’t know of a way to parse the tag ID number, though.
