When the verb is in the 3rd person singular, the construction is potentially ambiguous between a passive se-construction, in which the NP is the subject of the verb, and an indefinite se-construction, in which the NP is the object of the verb. Different solutions were taken by the different corpora.

In Tycho Brahe, ambiguous cases are annotated, by default, as passive constructions:

( (IP-MAT (VB-D Queimava)
          (NP-SE-1 (CL se))
          (NP-SBJ-1 (N louro))
          (PP (P com)
              (NP (ADJ-P certos) (N-P betumes) (ADJ-P odoríferos))))

In Cordial-Sin, Post Scriptum and Wochwel, ambiguous cases are annotated, by default, as impersonal constructions:

(IP-MAT (NP-SBJ-1 *exp*)
        (PP (P @A)
            (NP (D-F-P @as)
                (N-P vezes)))
        (VB-P-3S apanha@)

                     (NP  (DEM @aquilo))))
