The facts of ; (Standard American) English seem to be that finite non-wh relatives ; do not allow extraction of the highest subject, but non-finite ones ; do: ; ; (1) Kim likes the book Sandy bought. ; (2) *Kim likes the person buys books. ; (3) Kim found a book to buy for Sandy. ; (4) Kim found a person to buy Sandy a book. ; ; A simple hack involving case won't work, because embedded subjects ; can be extracted in the finite case: ; ; (5) Sandy likes the program Kim thinks works. ; ; Another tack is to treat (3) and (4) above differently, where ; the to in (3) is to_c_prop and the to in (4) is to_c_nonprop. ; The motivation for this is that the former allows a discourse ; PRO interpretation, while the latter doesn't, so it is tempting ; to says that the latter doesn't involve PRO at all. The idea is ; that to_c_prop builds a non_wh_rel which can then serve as a ; modifier, while to_c_nonprop has a MOD value to start off with, ; and can be a modifier directly once it builds a hcomp. To_c_nonprop ; would bind the index of its MOD value to that of its subject. ; ; However, this is unsatisfactory for several reasons. First, the ; ones like (4), built with to_c_nonprop, have no message for the ; relative. Second, since MOD is a head feature now, to_c_prop must ; also be MOD < nbar > . Once this is true, there is no obvious way to ; keep it from serving directly as a modifier without building a ; non_wh_rel. Finally, we run into problems with lexical SLASH ; amalgamation. Something has to be said about the subject value of ; to_c_nonprop, otherwise it runs the risk of having a non-terminated ; SLASH value. However, on the one hand, to_c_nonprop is the to of ; raising constructions, so sometimes its SUBJ must be able to be ; canonical_synsem, and on the other, on this analysis, it can also ; head modifiers in which its SUBJ goes unexpressed. To take care ; of the latter, something must be said in the lexical entry, but ; unexpressed is not compatible with canonical_synsem. ; ; The only other possibility I can see is to let the subject extraction ; apply lower, as in to [like Sandy] in [a person to like Sandy], but ; this requires letting subject extraction apply to base forms, which ; would most likely be a royal mess. ; ; In sum, given the facts of SAE and the rest of the grammar as ; it is, (3) and (4) must be built with the same to. In (3) there ; is an extracted complement and in (4) there is an extracted ; subject. In the case of infinitival non_wh_rels, the grammar ; doesn't care.

The SLASH value is not set in the basic ; schema, but rather in each of the subtypes: in head_mod_phrase_simple the ; SLASH value is passed up from both daughters, but in the ; extracted_adj_phrase the SLASH value of the mother is effectively the ; adjunct that would have modified the head. ; ; DPF (6-Sept-98) Constrained HD-DTR to have empty QUE as well as REL, to ; block adverbs modifying "how", "where", etc. ; DPF (4-Mar-99) But this unfortunately also blocks "which consultant who fell" ; since making "consultant" be QUE empty means via lexical threading that its ; specifier must also be QUE empty. So we would have to find some other way of ; blocking modifiers of "where" etc, but perhaps the generalization is wrong ; anyway; consider "right where", "exactly when" "just how". ; DPF 25-Aug-99 - Removed CONJ cnil from HD-DTR, to allow "oh, and your name" ; DPF 6-Apr-01 - Mysteriously, it seems that we have not been copying up ALTMIN ; from head-dtr to mother for head-mod phrases.

Most modifiers identify their message with their ; modifiee's message, but tags don't. (Modifiers cannot simply identify their ; own message with that of their modifiee, since some signs (like "not") ; can be either a modifier or an argument, and hence need a message value ; independent of that of their modifiee. ; SLASH of mother is append of SLASH lists for the two daughters. In principle ; this allows distinct slash values on the two daughters, without enforcing ; parasitic gaps.

Rather we want the SORT of the dtr to ; constrain the ARG0 of the derived "PP" itself (its E-INDEX), not what the PP ; modifies. ; DPF 09-Jun-03 - Made dtr be MODIFD.LPERIPH bool to exclude "Kim arrived ; times I left" ; DPF 22-Jul-03 - Might think to make SPR's MIN be much_deg_rel rather than ; simply degree_rel to avoid spurious ambig for "right now", given two entries ; "right" for 'very' and 'much' type degree specifiers.

Fixed ; DPF 01-may-04 - Continuing the pendulum swing of 2-Sept-00 and 17-Jul-01, ; removed SPR again, since we get "right now" as an NP, and have just added ; an analysis for "too late" and "too long" where these gradable NPs take ; "too", "very", etc. before pumping to PP. ; DPF 25-sept-04 - Removed SYNSEM..MOD..MSG no_msg, since we want to allow ; e.g. 'tomorrow, can you come' using adj_i_ques rule. Rather, make MSG ; value same as that of MOD, like ordinary prepositions. ; DPF 12-nov-05 - Added MOD..NORM norm_rel to prevent these from ; modifying lexical NP-adverbials as in e.g. "here there" ; DPF 05-dec-05 - Re: 25-sep-01 - Not clear what that comment meant, but ; removed AGR reentrancy since this was preventing e.g. "Here lies Kim" ; where the AGR ends up not being of type 'index' ; DPF 30-sept-06 - Re: 12-nov-05: But this interferes in interaction with ; appositives, as in "the manager today, Abrams, arrives."

So in the base case (the ; first time this rule applies in a series of mid-conj's), the left dtr is ; optionally marked with a comma (RPUNCT comma_or_no_punct), but since the ; mother is [LPUNCT no_punct, RPUNCT comma_punct], the only way this rule ; can reapply is if the phrase picks up a left comma in order to match the ; requirement on the right dtr's LPUNCT. (This arrangement looks like it ; would in principle accept a double comma on the left dtr in a recursively ; applied structure, as in "Abrams, Browne,, Chiang, and Devito", but the ; preprocessor doesn't admit the two successive commas, so we can live with ; this flaw for now.) ; [ abrams [, [ browne [ and Chiang ]]]] ; [ abrams [, [ [ browne ,] [ and Chiang ]]]]] ; [ devito [, [ abrams [, [ [ browne ,] [ and Chiang ]]]]] ; This means that we get a spurious analysis for complex conjunctions where the ; conjoined phrase ends in a comma or period, since that licenses a left comma ; on the final conjunct: [arise [, smile [, [and [ go .]]]]]. FIX?? later. ; DPF 10-may-05 - Use new feature PUNCT.PAIRED to enable constraint on presence ; of commas in three (or more) part coordination, ensuring that if the ; next-to-last conjunct is comma-marked, all leftward conjuncts are too, ; while if the next-to-last conjunct is not comma-marked, the next one ; doesn't have to be either, but can be. The way it works is that the ; affixation rule for comma punctuation stamps [PAIRED no-ppair], while ; a non-punctuated sign is underspecified for PAIRED. This mid_coord_rule ; type propagates that PAIRED property up from its left dtr, so it's still ; visible on the mid-coordinated phrase. Then the top_coord_rule requires ; that its left dtr unifies its PUNCT.PNCTPR value with the PAIRED value of ; its right dtr. The effect is that if the next-to-last conjunct is unmarked, ; it will not restrict the PNCTPR value of the top conjunct, but if the ; next-to-last is comma-marked, it imposes a constraint (eventually) on the ; top conjunct's PNCTPR value, forcing it to be a comma. basic_mid_coord_rule := binary_rule_right_to_left & basic_coord_phr & [ SYNSEM [ LOCAL.CONJ phr-conj & [ CHEAD #chead, CREL basic_conj_relation & [ LBL #ltop, PRED implicit_conj_rel, ARG0 #cind & non_expl, R-INDEX #ind ] ], PUNCT [ LPUNCT no_punct, RPUNCT #rpunct, PAIRED #paired, PNCTPR #rpnctpr] ], LCONJ-DTR.SYNSEM [ LOCAL.CONJ cnil, PUNCT [ LPUNCT no_punct, RPUNCT comma_or_no_punct, PNCTPR #pnctpr, PAIRED #paired ] ], RCONJ-DTR.SYNSEM [ LOCAL [ CONT.HOOK.INDEX #ind, CONJ complex-conj & [ CHEAD #chead ] ], PUNCT [ LPUNCT no_punct, RPUNCT #rpunct, PAIRED #pnctpr, PNCTPR #rpnctpr ] ], C-CONT.HOOK [ LTOP #ltop, INDEX #cind & conj-ind ] ]. ; Not NP mid-coord, whose LTOP must be free. ; mid_coord_rule := basic_mid_coord_rule & [ SYNSEM.LOCAL.CONJ.CREL.LBL #ltop, C-CONT.HOOK.LTOP #ltop ]. ; Edited variant requires left dtr to be comma marked. mid_coord_edgen_rule := mid_coord_rule & [ LCONJ-DTR.SYNSEM.PUNCT.RPUNCT comma_punct ]. ; Informal variant has no comma on left dtr mid_coord_infgen_rule := mid_coord_rule & [ LCONJ-DTR.SYNSEM.PUNCT.RPUNCT no_punct, GENRE nonformal ]. ; Coordination of non-nominal phrases (S's and VPs) ;; DPF 25-Feb-01 - Changed division of labor with these two rules, so the first now ;; conjoins all phrases with event index values, while the second conjoins nominal ;; phrases. ;; DPF 21-Aug-01 - Added E-INDEX.E.TENSE real_tense to both dtrs in order to ;; block conjunction of no-copula VPs (want the no-cop after conjunction). ;; DPF 12-Oct-06 - Changed determination of mother's TAM to come from first ;; daughter rather than second.
