Lab 4 Grading Rubric Notes: I think we discussed this at some point. The way to get the free order between the two complements of a ditransitive is to instantiate basic-head-2nd-comp-phrase. You didn't describe what you did for object optionality, nor what the facts are in Finnish. Your head-adj rules are probably overgenerating because you haven't constrained your non-modifier parts of speech to be [MOD <>]. Adding [MOD <>] to the defintion (addendum statement, actually) for noun, brought the number of parses for "minA annan tomaatit miehelle" down to one. Your write up does not describe agreement between adjectives and the nouns they modify, but your grammar seems to be implementing it. Please use full sentences in your write up to illustrate your points. I'd like to test the "big red house" example and give you some feedback on the attachment sites, but I can't without a full sentence (I don't feel like poking around in the parse chart). Your inflectional rules for adjectives need to specify the HEAD value of the mother: since you're inheriting from infl-head-change-only-ltol-rule, the type isn't copying up the HEAD values. If adj-lex doesn't say anything about the CASE value inside MOD, you could actually use infl-add-only-nocont-ltol-rule instead. The write up instructions requested that you describe how you tested your analyses (preferably with examples I can play with). You should also include more detail in the write up about the lexical types you added for modifiers. The constraints on the SUBJ appear to be common to all your verb types, and could be pulled up to verb-lex. dtr-verb-lex seems to be underspecified: it's not requiring, as far as I can tell, any of its arguments to be saturated ([SPR <>]) constituents. I see that you're handling it this way: ;; RGM 4-28-05 Fixed a head-comp-phrase overgeneration bug by restricting ;; the NON-HEAD-DTR to be a headed-phrase. This killed complements that were ;; only words. That is to say, complements can be single words, but they ;; better be phrasally licensed by a bare-np-phrase first. ... but you may want complements that are only words at some point. (Or, with coordinate NPs, complements that are phrasal but not, at the top level, headed-phrases.) Better, in my opinion, to constrain dtr-verb-lex (parallel to what you have for tr-verb-lex and itr-verb-lex). You know, any one of these overgeneration issues would have been a perfectly fine thing to post to EPost about... You're right that you need to add something to the adv-lex definition to force VP attachment (and rule out S attachment). Requiring a non-empty SUBJ value (parallel to your non-empty SPR value) on the MOD should do it.
