"abstract": "This paper argues that various kinds of displaced structures in English should be licensed by a more explicitly formulated type of rule schema in order to deal with what is called weak connectivity in English. This paper claims that the filler and the gap site cannot maintain the total identity of features but a partial overlap since the two positions need to obey the structural forces that come from occupying respective positions. One such case is the missing object construction where the subject fillers and the object gaps are to observe requirements that are imposed on the respective positions. Others include passive constructions and topicalized structures. In this paper, it is argued that the feature discrepancy comes from the different syntactic positions in which the fillers are assumed to be located before and after displacement. In order to capture this type of mismatch, syntactically relevant features are handled separately from the semantically motivated features in order to deal with the syntactically imposed requirements.",

For instance, Hukari and Levine (1991) formulated a rule that ignores [CASE] feature in this construction, and Levine and Hukari (2006, p 355 ) also suggested a rule as shown in (5) (5) partial representation of SYNSEM value for tough lexical rule",

This is because the feature specification in the tough lexical rule explicitly mentions NP as the SLASH value. To correct this problem, we may loosen the lexical rule to such a degree that the filler and the gap may be minimally different from each other, and thus the SLASH value could be simply a phrase (i.e., XP) instead of an NP.

The problems with these examples are twofold: one involves a reanalysis assumption; the other relates to category mismatch as in MOCs. These examples show that passives are not simply a process of demoting and promoting some arguments. If the passive sentences like (3b) and (3c) are to be generated, there should be a process that concatenates relied and on, in addition to the ordinary passive lexical rule since rely on or think of cannot be an input the Passive Lexical Rule (PLR) of Sag and Wasow (1999, p235) as it is. Even though the verb-preposition sequence can somehow be fed into the Passive Lexical Rule, the least oblique complement cannot be S-bar or S, since it would be governed by a preposition, not by the verb in question, in the active counterpart. Furthermore, the PRL demotes the first element of ARG-STR value and promotes the least oblique argument in the remainder so that the category next to the main verb becomes the subject in ordinary cases. But this general rule would license the following ill-formed cases shown in (7a), (7b) and (7c). Furthermore, the well-formed ones in (7a'), (7b'), and (7c') are not generated by the PLR.",

In order to take care of this situation, some parochial passive rules need to be posited. What is clear is that the Sag and Wasow's (1999) PLR cannot deal with the examples shown above and that it has to be flanked with subsidiary rules. One instance of such rules that can deal with (7c') would look like the one proposed in (8) and this would take care of the two problems: need for reanalysis and categorical mismatch. In fact, the rule proposed by Sag and Wasow does not take care of the examples in (7a') and (7b'). This cannot be dealt with by a kind of extraposition operation, either, since the (7a) and (7b) are not well-formed sentences. Therefore, the passive forms without prepositions, like thought and said are to be dealt with separately from the ones with prepositions.",

Then there seems to be no apparatus within this version that can incorporate this generalized category (XP, for instance) into specific rules because a gap is a product of lexicon-internal operation regarding argument structure, but not a rule-to-rule operation. The point is that the lexicon-internal operation cannot deal with generalized categories like XP but fullfledged syntactic categories regarding part-of-speech features. The rule in (8), first, takes a verb-preposition sequence and changes it to a passive form and concatenates the preposition to the passive form. Second, the prepositional object is promoted to a subject position but the promoted one only carries an index identical to INDEX value of the original object.",

"text": "Topicalized constituents carry some special discourse functions that make the constituents prominent and such discourse properties seem to be shared by MOCs and Passives as well. Investigating into this discourse property in full length would be beyond the scope of this paper, but I will talk briefly about this property, assuming that the topic phrase, passive subject and MOC's subject act as a link between the preceding utterance and the following. Consider the following sentence. What is common among these constructions is that the constituents in question are discourse oriented and, thus, their grammatical functions are somewhat 'diluted' in the sense that the phrases in question are not adjacent to their lexical governor. In some cases, the meanings are not identical. For example, the third utterance in (11) is not identical to the compared pair in meaning and it may be the more appropriate form of utterance than the other in this context. So the category mismatch is somewhat related to non-adjacency to the lexical governor and this is common to many discourse-oriented constructions. So the solution to the mismatch should reflect this property. So the requirement imposed on this construction will be whether it is interpretable on a discourse level as well as on a semantic level. In the same way as we dealted with passives, the rule schema for the topicalized construction should be loosened as shown in (12):(12) Head-Filler Rule (Revised)",

"text": "What this rule does is to allow the mismatch between the filler and gap as long as they share a certain semantic property, that is, the same index. On a discourse level, some propositions can be referred to by nouns like the fact, the proposal, the assumption, and so on. This type of anaphoric reference may be reflected partially in the rule in (12). This formulation of head-filler rule may over-generate some ill-formed sentences like the ones in (13a) and (13c). In this paper, the solution to this over-generation will be sought based on the (im)possibility of a kind of reference or processing. In (13a), the awkwardness comes from semantic mismatch since the location role imposed by semantics of the verb put cannot be satisfied by the noun fact. This is why (13b) is also ill-formed. In other word, (13a) is not acceptable for the same reason that (13b) is unacceptable. As for (13c), we would say that there is no known (co-)reference relation between NP and PP, unlike the case of NP and S-bar 3 . Let us compare (13c) with (14): The kind of relation that is frequently found between NP and S-bar within or across sentences as shown in (14) cannot be found between NP and PP. We think this is why (13c) is unacceptable. The loosened head-filler rule in (12), however, may over-generate the ill-formed ones in (15b) and (15c):",
