A Lexical Theory of Quantification in Ambiguous Query Interpretation Abstract Although the connection between natural language syntax and semantics has received serious attention in both linguistics and computational linguistics for the last several decades, it does not appear that it has yet been entirely satisfactorily identified. The present dissertation focuses on quantifier scope ambiguity in an attempt to identify such a connection. We show that there are some readings that are incorrectly allowed by the theories and that other readings that are available are allowed for the wrong reason. First, we distinguish referential NP interpretations from quantificational NP interpretations. Most traditional theories of scope do not, and they are shown to significantly overgenerate readings and/or miss a crucial generalization regarding quantificationally va ailable readings. We present a hypothesis based on the notion of surface constituency to predict quantificationally va ailable readings. The hypothesis is tested on core English constructions, including transitive verbs, dative alternation (ditransitive) verbs, attitude verbs, complex NPs containing prepositional phrases, possessives, and subject or non-subject Wh-relatives also with pied-piping and various coordinate structures. We argue that the scopings allowed under the hypothesis are the ones that are available. We then present a competence theory of quantifier scope, couched in a combinatory categorial grammar framework. The theory defines the connection between syntax and semantics in a precise way, utilizing the dual quantifier eprr esentation. We show theoretical predictions on the core English constructions, and verify that the theoretical predictions are consistent with the predictions made by the hypothesis and that there are further reasonable theoretically predicted readings. Finally, we describe an implementation of the theory in Prolog. The implemented system takes English sentences as ambiguous queries (regarding scope), generates logical forms that are associated with them, and evaluates those logical forms with respect to a predefined database of facts. The system also works as a proof-checker of the theory. Comments University of Pennsylvania Institute for Research in Cognitive Science Technical Report No. IRCS-96-27.

  • Lexical and Syntactic Ambiguity As a Source of Humor: the Case of Newspaper Headlines
    Lexical and syntactic ambiguity as a source of humor: The case of newspaper headlines CHIARA BUCARIA Abstract The paper analyzes some forms of linguistic ambiguity in English in a specific register, i.e. newspaper headlines. In particular, the focus of the research is on examples of lexical and syntactic ambiguity that result in sources of voluntary or involuntary humor. The study is based on a corpus of 135 verbally ambiguous headlines found on web sites presenting humor- ous bits of information. The linguistic phenomena that contribute to create this kind of semantic confusion in headlines will be analyzed and divided into the three main categories of lexical, syntactic, and phonological ambi- guity, and examples from the corpus will be discussed for each category. The main results of the study were that, firstly, contrary to the findings of previous research on jokes, syntactically ambiguous headlines were found in good percentage in the corpus and that this might point to di¤erences in genre. Secondly, two new configurations for the processing of the disjunctor/connector order were found. In the first of these configurations the disjunctor appears before the connector, instead of being placed after or coinciding with the ambiguous element, while in the second one two ambig- uous elements are present, each of which functions both as a connector and a disjunctor. Keywords: Ambiguity; headlines; lexical; syntactic; disjunctor; connector.

  • Semantic Analysis on Sense of Ambiguity in the Headline Printed the Jakarta Post Published on March 13Th– April 13Th , 2015
    SEMANTIC ANALYSIS ON SENSE OF AMBIGUITY IN THE HEADLINE PRINTED THE JAKARTA POST PUBLISHED ON MARCH 13TH– APRIL 13TH , 2015 Erisa Kurniati Batanghari University [email protected] ABSTRACT This research was aim to find out the ambiguity which found in the headline of The Jakarta Post based on semantic analysis first classify it which one the most ambiguous (word, phrase or sentence), then the last interpret the sense of ambiguity based on semantic analysis. The researcher collected 100 data of headlines then reduced it into 10 data purposively the most ambiguous. There are 6 data of ambiguity interpreted into two interpretations and 4 data of ambiguity interpreted into three interpretations. From 10 data, the data researcher found a lexical ambiguity in the headlines of The Jakarta Post published on March 13th – April 13th, 2015. Key words: Semantic Analysis, Sense of Ambiguity. A. Background of the Study Nowadays, there are many ways to communicate with other due to the developments of technology. There are many media, whether electronic or printed media to share information and to keep in touch with the other. People can get the information about the development of the world and everything happens in a day from electronic and printed media. Newspaper, especially daily newspaper, has a big contribution for the people to get information about local or international events everyday because the news and information are up to date and accurate. As a consequence, there are many daily newspapers published in Indonesia and one of the daily English Newspaper is The Jakarta Post. Generally, people communicate perfectly and completely.

  • The Meaning of Language
    01:615:201 Introduction to Linguistic Theory Adam Szczegielniak The Meaning of Language Copyright in part: Cengage learning The Meaning of Language • When you know a language you know: • When a word is meaningful or meaningless, when a word has two meanings, when two words have the same meaning, and what words refer to (in the real world or imagination) • When a sentence is meaningful or meaningless, when a sentence has two meanings, when two sentences have the same meaning, and whether a sentence is true or false (the truth conditions of the sentence) • Semantics is the study of the meaning of morphemes, words, phrases, and sentences – Lexical semantics: the meaning of words and the relationships among words – Phrasal or sentential semantics: the meaning of syntactic units larger than one word Truth • Compositional semantics: formulating semantic rules that build the meaning of a sentence based on the meaning of the words and how they combine – Also known as truth-conditional semantics because the speaker’ s knowledge of truth conditions is central Truth • If you know the meaning of a sentence, you can determine under what conditions it is true or false – You don’ t need to know whether or not a sentence is true or false to understand it, so knowing the meaning of a sentence means knowing under what circumstances it would be true or false • Most sentences are true or false depending on the situation – But some sentences are always true (tautologies) – And some are always false (contradictions) Entailment and Related Notions • Entailment: one sentence entails another if whenever the first sentence is true the second one must be true also Jack swims beautifully.

  • Notes on Generalized Quantifiers
    Notes on generalized quantifiers Ann Copestake ([email protected]), Computer Lab Copyright c Ann Copestake, 2001–2012 These notes are (minimally) adapted from lecture notes on compositional semantics used in a previous course. They are provided in order to supplement the notes from the Introduction to Natural Language Processing module on compositional semantics. 1 More on scope and quantifiers In the introductory module, we restricted ourselves to first order logic (or subsets of it). For instance, consider: (1) every big dog barks 8x[big0(x) ^ dog0(x) ) bark0(x)] This is first order because all predicates take variables denoting entities as arguments and because the quantifier (8) and connective (^) are part of standard FOL. As far as possible, computational linguists avoid the use of full higher-order logics. Theorem-proving with any- thing more than first order logic is problematic in general (though theorem-proving with FOL is only semi-decidable and that there are some ways in which higher-order constructs can be used that don’t make things any worse). Higher order sets in naive set theory also give rise to Russell’s paradox. Even without considering inference or denotation, higher-order logics cause computational problems: e.g., when deciding whether two higher order expressions are potentially equivalent (higher-order unification). However, we have to go beyond standard FOPC to represent some constructions. We need modal operators such as probably. I won’t go into the semantics of these in detail, but we can represent them as higher-order predicates. For instance: probably0(sleep0(k)) corresponds to kitty probably sleeps.

  • Two-Dimensionalism: Semantics and Metasemantics
    Two-Dimensionalism: Semantics and Metasemantics YEUNG, \y,ang -C-hun ...:' . '",~ ... ~ .. A Thesis Submitted in Partial Fulfilment of the Requirements for the Degree of Master of Philosophy In Philosophy The Chinese University of Hong Kong January 2010 Abstract of thesis entitled: Two-Dimensionalism: Semantics and Metasemantics Submitted by YEUNG, Wang Chun for the degree of Master of Philosophy at the Chinese University of Hong Kong in July 2009 This ,thesis investigates problems surrounding the lively debate about how Kripke's examples of necessary a posteriori truths and contingent a priori truths should be explained. Two-dimensionalism is a recent development that offers a non-reductive analysis of such truths. The semantic interpretation of two-dimensionalism, proposed by Jackson and Chalmers, has certain 'descriptive' elements, which can be articulated in terms of the following three claims: (a) names and natural kind terms are reference-fixed by some associated properties, (b) these properties are known a priori by every competent speaker, and (c) these properties reflect the cognitive significance of sentences containing such terms. In this thesis, I argue against two arguments directed at such 'descriptive' elements, namely, The Argument from Ignorance and Error ('AlE'), and The Argument from Variability ('AV'). I thereby suggest that reference-fixing properties belong to the semantics of names and natural kind terms, and not to their metasemantics. Chapter 1 is a survey of some central notions related to the debate between descriptivism and direct reference theory, e.g. sense, reference, and rigidity. Chapter 2 outlines the two-dimensional approach and introduces the va~ieties of interpretations 11 of the two-dimensional framework.

  • Leibniz and the Necessity of the Best Possible World
    This is a preprint of an article whose final and definitive form will be published in the Australasian Journal of Philosophy; the Australasian Journal of Philosophy is available online at: http://www.tandf.co.uk/journals/. LEIBNIZ AND THE NECESSITY OF THE BEST POSSIBLE WORLD Martin Pickup Leibniz has long faced a challenge about the coherence of the distinction between necessary and contingent truths in his philosophy. In this paper, I propose and examine a new way to save genuine contingency within a Leibnizian framework. I conclude that it succeeds in formally solving the problem, but at unbearable cost. I present Leibniz’s challenge by considering God’s choice of the best possible world (Sect. 2). God necessarily exists and necessarily chooses to actualise the best possible world. The actual world therefore could not be different, for if it were different it would be a distinct and inferior world and hence would not be created. In Sect. 3 I defend Leibniz from this challenge. I argue that while it is necessary for God to choose to create the best possible world, it is not necessary for any world to be the best possible. This is because the criterion for judging perfection can itself be contingent. Different criteria will judge different worlds as the best. Thus it is necessary for God to create the best, but not necessary which is the best. Distinguishing between possible worlds in Leibniz’s sense and in the modern sense allows a fuller exposition of this position. There are worries that can arise with the claim that the criterion of perfection is contingent.

  • Against Logical Form
    Against logical form Zolta´n Gendler Szabo´ Conceptions of logical form are stranded between extremes. On one side are those who think the logical form of a sentence has little to do with logic; on the other, those who think it has little to do with the sentence. Most of us would prefer a conception that strikes a balance: logical form that is an objective feature of a sentence and captures its logical character. I will argue that we cannot get what we want. What are these extreme conceptions? In linguistics, logical form is typically con- ceived of as a level of representation where ambiguities have been resolved. According to one highly developed view—Chomsky’s minimalism—logical form is one of the outputs of the derivation of a sentence. The derivation begins with a set of lexical items and after initial mergers it splits into two: on one branch phonological operations are applied without semantic effect; on the other are semantic operations without phono- logical realization. At the end of the first branch is phonological form, the input to the articulatory–perceptual system; and at the end of the second is logical form, the input to the conceptual–intentional system.1 Thus conceived, logical form encompasses all and only information required for interpretation. But semantic and logical information do not fully overlap. The connectives “and” and “but” are surely not synonyms, but the difference in meaning probably does not concern logic. On the other hand, it is of utmost logical importance whether “finitely many” or “equinumerous” are logical constants even though it is hard to see how this information could be essential for their interpretation.

  • Scope Ambiguity in Syntax and Semantics
    Scope Ambiguity in Syntax and Semantics Ling324 Reading: Meaning and Grammar, pg. 142-157 Is Scope Ambiguity Semantically Real? (1) Everyone loves someone. a. Wide scope reading of universal quantifier: ∀x[person(x) →∃y[person(y) ∧ love(x,y)]] b. Wide scope reading of existential quantifier: ∃y[person(y) ∧∀x[person(x) → love(x,y)]] 1 Could one semantic representation handle both the readings? • ∃y∀x reading entails ∀x∃y reading. ∀x∃y describes a more general situation where everyone has someone who s/he loves, and ∃y∀x describes a more specific situation where everyone loves the same person. • Then, couldn’t we say that Everyone loves someone is associated with the semantic representation that describes the more general reading, and the more specific reading obtains under an appropriate context? That is, couldn’t we say that Everyone loves someone is not semantically ambiguous, and its only semantic representation is the following? ∀x[person(x) →∃y[person(y) ∧ love(x,y)]] • After all, this semantic representation reflects the syntax: In syntax, everyone c-commands someone. In semantics, everyone scopes over someone. 2 Arguments for Real Scope Ambiguity • The semantic representation with the scope of quantifiers reflecting the order in which quantifiers occur in a sentence does not always represent the most general reading. (2) a. There was a name tag near every plate. b. A guard is standing in front of every gate. c. A student guide took every visitor to two museums. • Could we stipulate that when interpreting a sentence, no matter which order the quantifiers occur, always assign wide scope to every and narrow scope to some, two, etc.? 3 Arguments for Real Scope Ambiguity (cont.) • But in a negative sentence, ¬∀x∃y reading entails ¬∃y∀x reading.

  • On the Logic of Two-Dimensional Semantics
    Matrices and Modalities: On the Logic of Two-Dimensional Semantics MSc Thesis (Afstudeerscriptie) written by Peter Fritz (born March 4, 1984 in Ludwigsburg, Germany) under the supervision of Dr Paul Dekker and Prof Dr Yde Venema, and submitted to the Board of Examiners in partial fulfillment of the requirements for the degree of MSc in Logic at the Universiteit van Amsterdam. Date of the public defense: Members of the Thesis Committee: June 29, 2011 Dr Paul Dekker Dr Emar Maier Dr Alessandra Palmigiano Prof Dr Frank Veltman Prof Dr Yde Venema Abstract Two-dimensional semantics is a theory in the philosophy of language that pro- vides an account of meaning which is sensitive to the distinction between ne- cessity and apriority. Usually, this theory is presented in an informal manner. In this thesis, I take first steps in formalizing it, and use the formalization to present some considerations in favor of two-dimensional semantics. To do so, I define a semantics for a propositional modal logic with operators for the modalities of necessity, actuality, and apriority that captures the relevant ideas of two-dimensional semantics. I use this to show that some criticisms of two- dimensional semantics that claim that the theory is incoherent are not justified. I also axiomatize the logic, and compare it to the most important proposals in the literature that define similar logics. To indicate that two-dimensional semantics is a plausible semantic theory, I give an argument that shows that all theorems of the logic can be philosophically justified independently of two-dimensional semantics. Acknowledgements I thank my supervisors Paul Dekker and Yde Venema for their help and encour- agement in preparing this thesis.

  • On Considering a Possible World As Actual
    ON CONSIDERING A POSSIBLE WORLD AS ACTUAL Robert Stalnaker “Hell is paved with primary intensions” English proverb1 1. Introduction In Naming and Necessity2, Saul Kripke presented some striking examples that convinced many philosophers that there are truths that are both necessary and a posteriori, and also truths that are both contingent and a priori. The classic examples of the former are identity statements containing proper names (Hesperus = Phosphorus) and statements about the nature of natural kinds (Gold has atomic number 79). Realistic examples of the second kind of statement are harder to come by - perhaps there are none - but once one sees the idea it is easy to construct artificial examples. The most famous example is based on Gareth Evans’s descriptive name “Julius.”3 “Julius” is, by stipulation, a proper name of the person (whoever he might be) who invented the zip. So the statement “Julius invented the zip” can be known a priori to be true, but since the description is used to fix the reference rather than to give the meaning , of the name, the fact that Julius invented the zip is a contingent fact. Someone other than Julius (the person we in fact named) might have invented the zip, and if some else had invented it instead, it would not have been true that Julius invented the zip. The divergence of the two distinctions was surprising, but the examples are simple and relatively transparent. Kripke’s exposition pointed the way to an abstract description of the phenomena that made it clear, on one level at least, what is going on.

  • Quantification of Damages , in 3 ISSUES in COMPETITION LAW and POLICY 2331 (ABA Section of Antitrust Law 2008)
    Theon van Dijk & Frank Verboven, Quantification of Damages , in 3 ISSUES IN COMPETITION LAW AND POLICY 2331 (ABA Section of Antitrust Law 2008) Chapter 93 _________________________ QUANTIFICATION OF DAMAGES Theon van Dijk and Frank Verboven * This chapter provides a general economic framework for quantifying damages or lost profits in price-fixing cases. We begin with a conceptual framework that explicitly distinguishes between the direct cost effect of a price overcharge and the subsequent indirect pass-on and output effects of the overcharge. We then discuss alternative methods to quantify these various components of damages, ranging from largely empirical approaches to more theory-based approaches. Finally, we discuss the law and economics of price-fixing damages in the United States and Europe, with the focus being the legal treatment of the various components of price-fixing damages, as well as the legal standing of the various groups harmed by collusion. 1. Introduction Economic damages can be caused by various types of competition law violations, such as price-fixing or market-dividing agreements, exclusionary practices, or predatory pricing by a dominant firm. Depending on the violation, there are different parties that may suffer damages, including customers (direct purchasers and possibly indirect purchasers located downstream in the distribution chain), suppliers, and competitors. Even though the parties damaged and the amount of the damage may be clear from an economic perspective, in the end it is the legal framework within a jurisdiction that determines which violations can lead to compensation, which parties have standing to sue for damages, and the burden and standard of proof that must be met by plaintiffs and defendants.
