Layers and Operators in Lakota1 Avelino Corral Esteban Universidad Autónoma De Madrid
Kansas Working Papers in Linguistics, Vol. 36 (2015), 1-33 Layers and operators in Lakota1 Avelino Corral Esteban Universidad Autónoma de Madrid Abstract Categories covering the expression of grammatical information such as aspect, negation, tense, mood, modality, etc., are crucial to the study of language universals. In this study, I will present an analysis of the syntax and semantics of these grammatical categories in Lakota within the Role and Reference Grammar framework (hereafter RRG) (Van Valin 1993, 2005; Van Valin and LaPolla 1997), a functional approach in which elements with a purely grammatical function are treated as ´operators`. Many languages mark Aspect-Tense- Mood/Modality information (henceforth ATM) either morphologically or syntactically. Unlike most Native American languages, which exhibit an extremely complex verbal morphological system indicating this grammatical information, Lakota, a Siouan language with a mildly synthetic / partially agglutinative morphology, expresses information relating to ATM through enclitics, auxiliary verbs and adverbs, rather than by coding it through verbal affixes. 1. Introduction The organisation of this paper is as follows: after a brief account of the most relevant morpho- syntactic features exhibited by Lakota, Section 2 attempts to shed light on the distinction between lexical words, enclitics and affixes through evidence obtained in the study of this language. Section 3 introduces the notion of ´operator` and explores the ATM system in Lakota using RRG´s theory of operator system. After a description of each grammatical category, an analysis of the linear order exhibited by the Lakota operators with respect to the nucleus of the clause are analysed in Section 4, showing that this ordering reflects the scope relations between the grammatical categories conveyed by these operators. -
(2012) Perspectival Discourse Referents for Indexicals* Maria
To appear in Proceedings of SULA 7 (2012) Perspectival discourse referents for indexicals* Maria Bittner Rutgers University 0. Introduction By definition, the reference of an indexical depends on the context of utterance. For ex- ample, what proposition is expressed by saying I am hungry depends on who says this and when. Since Kaplan (1978), context dependence has been analyzed in terms of two parameters: an utterance context, which determines the reference of indexicals, and a formally unrelated assignment function, which determines the reference of anaphors (rep- resented as variables). This STATIC VIEW of indexicals, as pure context dependence, is still widely accepted. With varying details, it is implemented by current theories of indexicali- ty not only in static frameworks, which ignore context change (e.g. Schlenker 2003, Anand and Nevins 2004), but also in the otherwise dynamic framework of DRT. In DRT, context change is only relevant for anaphors, which refer to current values of variables. In contrast, indexicals refer to static contextual anchors (see Kamp 1985, Zeevat 1999). This SEMI-STATIC VIEW reconstructs the traditional indexical-anaphor dichotomy in DRT. An alternative DYNAMIC VIEW of indexicality is implicit in the ‘commonplace ef- fect’ of Stalnaker (1978) and is formally explicated in Bittner (2007, 2011). The basic idea is that indexical reference is a species of discourse reference, just like anaphora. In particular, both varieties of discourse reference involve not only context dependence, but also context change. The act of speaking up focuses attention and thereby makes this very speech event available for discourse reference by indexicals. Mentioning something likewise focuses attention, making the mentioned entity available for subsequent dis- course reference by anaphors. -
Acquaintance Inferences As Evidential Effects
The acquaintance inference as an evidential effect Abstract. Predications containing a special restricted class of predicates, like English tasty, tend to trigger an inference when asserted, to the effect that the speaker has had a spe- cific kind of `direct contact' with the subject of predication. This `acquaintance inference' has typically been treated as a hard-coded default effect, derived from the nature of the predicate together with the commitments incurred by assertion. This paper reevaluates the nature of this inference by examining its behavior in `Standard' Tibetan, a language that grammatically encodes perceptual evidentiality. In Tibetan, the acquaintance inference trig- gers not as a default, but rather when, and only when, marked by a perceptual evidential. The acquaintance inference is thus a grammaticized evidential effect in Tibetan, and so it cannot be a default effect in general cross-linguistically. An account is provided of how the semantics of the predicate and the commitment to perceptual evidentiality derive the in- ference in Tibetan, and it is suggested that the inference ought to be seen as an evidential effect generally, even in evidential-less languages, which invoke evidential notions without grammaticizing them. 1 Introduction: the acquaintance inference A certain restricted class of predicates, like English tasty, exhibit a special sort of behavior when used in predicative assertions. In particular, they require as a robust default that the speaker of the assertion has had direct contact of a specific sort with the subject of predication, as in (1). (1) This food is tasty. ,! The speaker has tasted the food. ,! The speaker liked the food's taste. -

INTRODUCTION Does it matter that the editors of thirty-three law journals, including those at Yale and Michigan, think that there is a "passive tense"? l Does it matter that the United States Courts of Appeals for the Sixth2 and Eleventh3 Circuits think that there is a "passive mood"? Does it matter that the editors of fourteen law reviews think that there is a "subjunctive tense"?4 Does it matter that the United States Court of Appeals for the District of Columbia Circuit thinks that there is a "subjunctive voice'"? 5 There is, in fact, no "passive tense" or "passive mood." The passive is a voice. 6 There is no "subjunctive voice" or "subjunctive tense." The subjunctive is a mood.7 The examples in the first paragraph suggest that there is widespread unfamiliarity among lawyers and law students * B.A., Trinity College; J.D., Harvard University; Professor, Quinnipiac University School of Law. -

Chapter 1 Negation in a Cross-Linguistic Perspective
Chapter 1 Negation in a cross-linguistic perspective 0. Chapter summary This chapter introduces the empirical scope of our study on the expression and interpretation of negation in natural language. We start with some background notions on negation in logic and language, and continue with a discussion of more linguistic issues concerning negation at the syntax-semantics interface. We zoom in on cross- linguistic variation, both in a synchronic perspective (typology) and in a diachronic perspective (language change). Besides expressions of propositional negation, this book analyzes the form and interpretation of indefinites in the scope of negation. This raises the issue of negative polarity and its relation to negative concord. We present the main facts, criteria, and proposals developed in the literature on this topic. The chapter closes with an overview of the book. We use Optimality Theory to account for the syntax and semantics of negation in a cross-linguistic perspective. This theoretical framework is introduced in Chapter 2. 1 Negation in logic and language The main aim of this book is to provide an account of the patterns of negation we find in natural language. The expression and interpretation of negation in natural language has long fascinated philosophers, logicians, and linguists. Horn’s (1989) Natural history of negation opens with the following statement: “All human systems of communication contain a representation of negation. No animal communication system includes negative utterances, and consequently, none possesses a means for assigning truth value, for lying, for irony, or for coping with false or contradictory statements.” A bit further on the first page, Horn states: “Despite the simplicity of the one-place connective of propositional logic ( ¬p is true if and only if p is not true) and of the laws of inference in which it participate (e.g. -
The Logic of Argument Structure
32 San Diego Linguistic Papers 3 (2008) 32-125 Circumstances and Perspective: The Logic of Argument Structure Jean Mark Gawron San Diego State University 1 Introduction The fox knows many things but the hedgehog knows one big thing. Archilochus cited by Isaiah Berlin Berlin (1997:“The Hedgehog and the Fox”) The last couple of decades have seen substantial progress in the study of lexical semantics, particularly in contributing to the understanding of how lexical semantic properties interact with syntactic properties, but many open questions await resolution before a consensus of what a theory of lexical semantics looks like is achieved. Two properties of word meanings contribute to the difficulty of the problem. One is the openness of word meanings. The variety of word meanings is the variety of human experience. Consider defining words such as ricochet, barber, alimony, seminal, amputate, and brittle. One needs to make reference to diverse practices, processes, and objects in the social and physical world: the impingement of one object against another, grooming and hair, marriage and divorce, discourse about concepts and theories, and events of breaking. Before this seemingly endless diversity, semanticists have in the past stopped short, excluding it from the semantic enterprise, and attempting to draw a line between a small linguistically significant set of concepts and the openness of the lexicon. The other problem is the closely related problem of the richness of word meanings. Words are hard to define, not so much because they invoke fine content specific distinctions, but because they invoke vast amounts of background information. The concept of buying presupposes the complex social fact of a commercial event. -
Grounding Lexical Meaning in Core Cognition
Grounding Lexical Meaning in Core Cognition Noah D. Goodman December 2012 (Updated June 2013) Abstract Author's note: This document is a slightly updated and reformatted extract from a grant proposal to the ONR. As a proposal, it aims describe useful directions while reviewing existing and pilot work; it has no pretensions to being a systematic, rigorous, or entirely coherent scholarly work. On the other hand, I've found that it provides a useful overview of a few ideas on the architecture of natural language that haven't yet appeared elsewhere. I provide it for those interested, but with all due caveats. Words are potentially one of the clearest windows on human knowledge and con- ceptual structure. But what do words mean? In this project we aim to construct and explore a formal model of lexical semantics grounded, via pragmatic inference, in core conceptual structures. Flexible human cognition is derived in large part from our ability to imagine possible worlds. A rich set of concepts, in- tuitive theories, and other mental representations support imagining and reasoning about possible worlds|together we call these core cognition. Here we posit that the collection of core concepts also forms the set of primitive elements available for lexi- cal semantics: word meanings are built from pieces of core cognition. We propose to study lexical semantics in the setting of an architecture for language understanding that integrates literal meaning with pragmatic inference. This architecture supports underspecified and uncertain lexical meaning, leading to subtle interactions between meaning, conceptual structure, and context. We will explore several cases of lexical semantics where these interactions are particularly important: indexicals, scalar adjec- tives, generics, and modals. -
Contradiction Detection with Contradiction-Specific Word Embedding
algorithms Article Contradiction Detection with Contradiction-Specific Word Embedding Luyang Li, Bing Qin * and Ting Liu Research Center for Social Computing and Information Retrieval, School of Computer Science and Technology, Harbin Institute of Technology, Haerbin 150001, China; [email protected] (L.L.); [email protected] (T.L.) * Correspondence: [email protected]; Tel.: +86-186-8674-8930 Academic Editor: Toly Chen Received: 18 January 2017; Accepted: 12 May 2017; Published: 24 May 2017 Abstract: Contradiction detection is a task to recognize contradiction relations between a pair of sentences. Despite the effectiveness of traditional context-based word embedding learning algorithms in many natural language processing tasks, such algorithms are not powerful enough for contradiction detection. Contrasting words such as “overfull” and “empty” are mostly mapped into close vectors in such embedding space. To solve this problem, we develop a tailored neural network to learn contradiction-specific word embedding (CWE). The method can separate antonyms in the opposite ends of a spectrum. CWE is learned from a training corpus which is automatically generated from the paraphrase database, and is naturally applied as features to carry out contradiction detection in SemEval 2014 benchmark dataset. Experimental results show that CWE outperforms traditional context-based word embedding in contradiction detection. The proposed model for contradiction detection performs comparably with the top-performing system in accuracy of three-category classification and enhances the accuracy from 75.97% to 82.08% in the contradiction category. Keywords: contradiction detection; word embedding; training data generation; neural network 1. Introduction Contradiction is a kind of semantic relation between sentences. -
Interpreting Focus
INTERPRETING FOCUS BART GEURTS ROB VAN DER SANDT UNIVERSITY OF NIJMEGEN UNIVERSITY OF NIJMEGEN B A R T.G E U R T S@P H I L.R U.N L R V D S A N D T@P H I L.K U N.N L Abstract Although it is widely agreed, if often only tacitly, that there is a close connection between focus and presupposition, recent research has tended to shy away from the null hypothesis, which is that focus is systematically associated with presupposition along the following lines: The Background-Presupposition Rule (BPR) Whenever focusing gives rise to a background λx.ϕ(x), there is a presup- position to the effect that λx.ϕ(x) holds of some individual. This paper aims to show, first, that the evidence in favour of the BPR is in fact rather good, and attempts to clarify its role in the interpretation of focus particles like ‘only’ and ‘too’, arguing that unlike the former the latter is focus-sensitive in an idiosyn- cratic way, adding its own interpretative constraints to those of the BPR. The last part of the paper discusses various objections that have been raised against the BPR, tak- ing a closer look at the peculiarities of ‘nobody’ and ‘somebody’, and comparing the interpretative effects of focusing with those of it-clefts. 26 1 Introduction The phenomenon generally known as focusing raises two questions. First: what is it? Second: how does it affect interpretation? This paper discusses the second question, and proposes a partial answer to it. The first question will not be addressed here. -
Ten Choices for Lexical Semantics
1 Ten Choices for Lexical Semantics Sergei Nirenburg and Victor Raskin1 Computing Research Laboratory New Mexico State University Las Cruces, NM 88003 {sergei,raskin}@crl.nmsu.edu Abstract. The modern computational lexical semantics reached a point in its de- velopment when it has become necessary to define the premises and goals of each of its several current trends. This paper proposes ten choices in terms of which these premises and goals can be discussed. It argues that the central questions in- clude the use of lexical rules for generating word senses; the role of syntax, prag- matics, and formal semantics in the specification of lexical meaning; the use of a world model, or ontology, as the organizing principle for lexical-semantic descrip- tions; the use of rules with limited scope; the relation between static and dynamic resources; the commitment to descriptive coverage; the trade-off between general- ization and idiosyncracy; and, finally, the adherence to the “supply-side” (method- oriented) or “demand-side” (task-oriented) ideology of research. The discussion is inspired by, but not limited to, the comparison between the generative lexicon ap- proach and the ontological semantic approach to lexical semantics. It is fair to say that lexical semantics, the study of word meaning and of its representation in the lexicon, experienced a powerful resurgence within the last decade.2 Traditionally, linguistic se- mantics has concerned itself with two areas, word meaning and sentence meaning. After the ascen- dancy of logic in the 1930s and especially after “the Chomskian revolution” of the late 1950s-early 1960s, most semanticists, including those working in the transformational and post-transforma- tional paradigm, focused almost exclusively on sentence meaning.
