Is there an option for ACE so that these cases can be handled?</p><p class=MsoNormal>Moreover, we came across the example “The phosphorus self-combusts.” vs ?“The phosphorus is self-combusted.” Where the first doesn’t parse, the second does, but doesn’t generate (again presumably because of "_combusted/VBN_u_unknown_rel"). It seems to not recognise verbs with a “self-“ prefix, but does for past participles.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Many thanks,</p><p class=MsoNormal>Alex</p></div></body></html>
