around as an ADP?

[AngledLuffa]

Is it a mistag? I would think this instance of around is an ADP.

# sent_id = GUM_vlog_covid-28

Also, in general I find myself wondering why around is never an RP in the XPOS this treebank, such as open up_RP vs come around_RB or close around_RB. Although it's not very consistent in PTB to label around as RP vs RB in turn around, get around, etc, it looks like RP is more common. However, this time around_RP, last time around_RP is consistent. Even this time around isn't 100% consistent, though

                    (NP
                      (ADJP (RB even) (JJR more) )
                      (NN caution) )
                    (PP (IN than)
                      (NP (DT the) (JJ first) (NN time) (RB around) ))))))))

"which was around like 6:00 pm" should be ADP, yes.

The idiom "this time around" (more generally "X time around") is interesting. My gut feeling is that "around" can be omitted so it is a modifier, presumably RB/ADV/advmod.

If memory serves RP should be aligned with compound:prt, which (unfortunately IMO) is defined in terms of idiomaticity. "come around" would presumably be RB/ADV/advmod if it is purely spatial and RP/ADP/compound:prt in the idiomatic meaning of 'change to my preferred opinion'.

Yes, this is an error, will fix

Indeed, it's not consistent in PTB, but while RP is more common in PTB proper, RB is more common overall in OntoNotes 5 (which also includes WSJ but much more other data as well). So in sum we went with the OntoNotes majority and decided to consistently tag it RB in these contexts.
