The result of questionnaire studies are presented which shows (i) that conjuncts are scope islands in Japanese and (ii) that left-node raising can nullify such scope islands. This finding confirms the theory advanced in Yatabe (2001), in which semantic composition is almost entirely carried out within order domains, and arguably contradicts the theory proposed in Beavers and Sag (2004), which introduces a mechanism called Optional Quantifier Merger to deal with the fact that right-node raising and left-node raising can have semantic effects.
The so-called floating quantifier constructions in languages like Korean display intriguing properties whose successful processing can prove the robustness of a parsing system. This paper shows that a constraint-based analysis, in particular couched upon the framework of HPSG, can offer us an efficient way of analyzing these constructions together with proper semantic representations. It also shows how the analysis has been successfully implemented in the LKB (Linguistic Knowledge Building) system.
In this paper I suggest an interface level of semantic representations, that on the one hand corresponds to morpho-syntactic entities such as phrase structure rules, function words and inflections, and that on the other hand can be mapped to lexical semantic representations that one ultimately needs in order to give good predictions about argument frames of lexical items. This interface level consists of basic constructions that can be decomposed into five sub-constructions (arg1-role, arg2-role ... arg5-role). I argue in favour of phrasal constructions in order to account for altering argument frames and maybe also coercion without having to use lexical rules or multiple lexical entries.
This paper provides a background on the role of world knowledge in disambiguating modals and proposes treating the disambiguation of counterfactuals as a slightly more tractable sub-case of the general problem. Using a model theoretic possible worlds approach, counterfactuals are disambiguated with respect to a world of evaluation resembling classic Formal Semantic treatments (e.g., Kratzer 1977, 1981, 1989; Lewis 1973; Veltman 2005). The world, which provides a context of evaluation, is located through the interaction of the antecedent and consequent propositions with world knowledge axioms. This approach to modal disambiguation provides a connection between a grammar and the type of inferences typically handled in Knowledge Representation Systems (e.g., Hobbs et al. 1990) in a limited domain. The model theoretic semantics are linked with typed feature structures in an HPSG syntax (Pollard and Sag 1994). This grammar is implemented in TRALE, Penn's (2004) Prolog-based framework for typed feature structure grammar development. The compositional semantics in TRALE is specified in Penn and Richters' (2004, 2005) Constraint Language for Lexical Resource Semantics (CLLRS). This semantic component provides a semantic parse in which heads and arguments are combined systematically and the scope of negation or quantification can be accurately reflected. In the case of counterfactuals, the CLLRS semantic parse is passed to a model-theoretic interpreter. The mapping between the CLLRS semantic parse and the well-formed formulas of the model is defined by checking the parseability of the formula in the compositional semantics. Sets of possible worlds interact with constraints on world knowledge and constraints defining counterfactual validity. The truth value for a counterfactual is returned to the grammar relative to a context of evaluation. The results of counterfactual evaluation are returned in a form consistent with the grammar's internal compositional semantics. By the method described above, the interpreter provides a grammar-external component in which inferences involving world knowledge have the potential to be more efficiently evaluated. Through the development of model-checking techniques, for instance, it could be shown whether or not well-formed formulas and constraints hold in larger models and move towards capturing more fine-grained modal inferences in a larger domain.
In this article, I will present a survey of control structures in Korean. The survey is based on a sample of seventy SOA-argument-taking predicates, which are classified with respect to their complementation patterns and control properties. As a result, Korean is characterized as a language in which semantically determined control is predominant, whereas constructionally induced control is only marginal. In the discussion of the sample, I will show that there are two major classes of verbs exhibiting semantic control: the first class consists of matrix verbs such as hwuhoyhata 'regret' or kangyohata 'force', which require obligatory coreference between a matrix argument and the embedded subject due to their lexical meaning. The verbs of the second class are utterance verbs such as malhata 'tell', which select clauses headed by the quotative complementizer ko. With these verbs, subject, object, or split control arises if specific modal suffixes are attached to the verb heading the complement clause. In the second part of the paper, I will provide a lexical analysis of control in Korean, which adopts the Principle of Controller Choice proposed by Farkas (1988) as well as additional constraints which have to be assumed independently.
In anaphora resolution theory, it has been assumed that anaphora resolution is based on a reversed mapping of antecedent salience and anaphora complexity: minimal complex anaphora refer to maximal salient antecedents. In order to ex-amine whether and by which developmental steps German children gain command of this mapping maxim we conducted an experiment on production and comprehension of intersentential pronouns including the three pronoun types zero, personal, and demonstrative pronoun. With respect to antecedent salience, the experiment varied syntactic role (subject/object) and in/animacy. Six age groups of children (age range from 2;0 to 6;0) and an adult control group has been tested. The hypothesis arising from the mapping maxim is that zero pronoun correlates with more salient antecedents than personal and demonstrative pronoun, the latter correlating with the least salient antecedents. The results are: In production, children first establish the opposition of zero pronoun with animate antecedents vs. demonstrative pronoun with inanimate antecedents. In a next step, syntactic role comes into play and a more complex system opposing the three presented pronoun types is established. In comprehension, however, the effect of pronoun type re-mains weak and antecedent features remain a strong factor in reference choice. However, also adults employ pronoun type and antecedent features. The oldest children and the adults show variation in personal pronoun resolution according to the animacy pattern of the potential antecedents. In case of identical animacy features, the subject is the preferred candidate; in case of distinct animacy features, there is a tendency to choose the object antecedent.
