I would:
1) avoid bothering with minting number IDs for each node; just let
the bnode carry it.
2) Use 'a' instead of :tag.

               (PP
                   of/IN
                   (NP
                       the/DT
                       company/NN
                   )
               )

@prefix pos: <http://eg.com/parts-of-speech#>

[ a pos:PP;
  pos:comprises (
    [ pos:string "of"; a pos:IN ]
    ( a pos:NP;
        pos:comprises (
            [ pos:string "the"; a pos:DT ]
            [ pos:string "company"; a pos:NN ]
        )
    )
 )
] .
