This is a partial list. On the left are the occurrence counts. It's not surprising that Jacy predicates are not covered by the ERG, but when they are very frequent it means that JaEn should perhaps have a hand-built rule to catch the cases when the automatically extracted rules fail to transfer something. In some cases, there is such a rule, but it has become outdated. For instance, neg_x is not covered because JaEn's rule still targets neg_v. Similarly, JaEn targets coord instead of coord_c.

And here's some of those that aren't covered on the ERG side:

  30754 EP 'def_q' is not covered
  16051 EP 'implicit_q' is not covered
   5386 EP '_good_a_at-for' is not covered

    259 EP '_i_n_num' is not covered
    240 EP 'numbered_hour' is not covered
    188 EP 'pron' is not covered

There some other reasons for these, but generally it's also because the hand-built JaEn rules are out of date. The def_q and implicit_q ones are because the modified SEM-I for the ERG missed.

_koto_n_nom can perhaps just be dropped, or be added to the auto-include set for my extractor (gets included in an extracted transfer rule even if it didn't exist in the predicate alignment, as long as it is incorporated into the rest of the MRS fragment).

unspec_adj and degree have the same count because they always co-occur. There should be a general rule or two written for these. Maybe:

;;; e.g. 2 キロ の 水 -- 2 kilograms of water
degree+unspec_adj--noun+of_p := monotonic_mtr &
[ INPUT.RELS < #m [ LBL #h1, ARG0 #x2 ],
               [ PRED "ja:degree", LBL #h3, ARG1 #e4, ARG2 #x2 ],
               [ PRED "ja:unspec_adj", LBL #h3, ARG0 #e4, ARG1 #x3 ],
               [ LBL #h3, ARG0 #x3 ] >,
  OUTPUT.RELS < #m [ LBL #h1, ARG0 #x2 ],
                [ PRED "_of_p_rel", LBL #h1, ARG1 #x2, ARG2 #x3 ],
                [ ARG0 #x3 ] > ].

and a different rule for the generic_entity case... although the rule above might be broken...

_you_n would be tough to write rules for... but maybe it can just be dropped.
