Development of a General-Purpose Categorial Grammar Treebank

It is ‘general-purpose’ in the sense that it is not tailored to a specific variant of CG, but rather aims to offer a theory-neutral linguistic resource (as much as possible) which can be converted to different versions of CG (specifically, CCG and Type-Logical Grammar) relatively easily. In terms of linguistic analysis, it improves over the existing Japanese CG treebank (Japanese CCGBank) on the treatment of certain linguistic phenomena (passives, causatives, and control/raising predicates) for which the lexical specification of the syntactic information reflecting local dependencies turns out to be crucial. In this paper, we describe the underlying ‘theory’ dubbed ABC Grammar that is taken as a basis for our treebank, outline the general construction of the corpus, and report on some preliminary results applying the treebank in a semantic parsing system for generating logical representations of sentences.

Direct Compositionality and Variable-Free Semantics: the Case of “Principle B”
Direct Compositionality and Variable-Free Semantics: The Case of “Principle B” Drafty outline/handout of material to be presented at the Workshop on Direct Compositionality Pauline Jacobson Brown University 0. The big picture goals: (A) To argue that direct compositionality is a much simpler hypothesis about the organization of the grammar than the competing views It is, therefore, the view we should hope is correct. Apparent challenges to this view should perhaps lead us to rethink some of the underlying assumptions which give rise to these challenges. (B) To point out: a consequence of at least a reasonably strong version of direct compositionality is that structured representations (e.g., trees) play no actual role in the grammar: they are not something that grammatical rules/principles can “see”. They are just convenient representation for the lnguist (representing the syntactic proof system and the compositional semantics) (C) To point out the consequences of this with respect to principles regarding the distribution of pronouns (reflexives, etc.). Standard assumption: these require the grammar to include principles which are stated on non strictly-local chucks of representation Hence: the hypothesis of direct compositionality should inspire us to rethink such statements (D) To discuss a second way in which binding principles have traditionally been taken to challenge direct compositionality (at least in its strong form): • there are many cases where there are binding type effects (e.g., "binding" of pronouns, "binding" of reflexives to satisfy Principle A, Principle B violations, etc.) but where on the surface, there is no big enough chunk of representation Typical example : connectivity in specificational sentences (1) What John is is proud of himself. -
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. -
Sequence-Of-Tense and the Features of Finite Tenses Karen Zagona University of Washington*
Sequence-of-tense and the Features of Finite Tenses Karen Zagona University of Washington* Abstract Sequence-of-tense (SOT) is often described as a (past) tense verb form that does not correspond to a semantically interpretable tense. Since SOT clauses behave in other respects like finite clauses, the question arises as to whether the syntactic category Tense has to be distinguished from the functional category tense. I claim that SOT clauses do in fact contain interpretable PRESENT tense. The “past” form is analyzed as a manifestation of agreement with the (matrix past) controller of the SOT clause evaluation time. One implication of this analysis is that finite verb forms should be analyzed as representing features that correspond to functional categories higher in clause structure, including those of the clausal left periphery. SOT morphology then sheds light on the existence of a series of finer- grained functional heads that contribute to tense construal, and to verbal paradigms. These include Tense, Modality and Force. 1. Introduction The phenomenon of sequence-of-tense (SOT) poses several challenges for the standard assumption that a “past tense” verb form signals the presence of a functional category in clause structure with an interpretable ‘past’ value. SOT is illustrated by the ‘simultaneous’ reading of sentence (1): (1) Terry believed that Sue was pregnant. a. The time of Sue’s pregnancy precedes time of Terry’s belief (precedence) b. The time of Sue’ pregnancy overlaps time of Terry’s belief (simultaneity) For the ‘precedence’ reading in (1a), the embedded clause tense is semantically transparent in the sense that the past form was corresponds to a past ordering relation (relative to the time of Terry’s belief). -

Categorial Grammar and Lexical-Functional Grammar∗
Categorial Grammar and Lexical-Functional Grammar¤ Reinhard Muskens Department of Linguistics Tilburg University The Netherlands Proceedings of the LFG01 Conference University of Hong Kong, Hong Kong Miriam Butt and Tracy Holloway King (Editors) 2001 CSLI Publications http://csli-publications.stanford.edu/ ¤I wish to thank the participants of LFG2001, especially Mary Dalrymple and Ron Kaplan, for valuable feedback. All comments are very welcome. Abstract This paper introduces ¸-grammar, a form of categorial grammar that has much in common with LFG. Like other forms of categorial grammar, ¸-grammars are multi-dimensional and their components are combined in a strictly parallel fashion. Grammatical representa- tions are combined with the help of linear combinators, closed pure ¸-terms in which each abstractor binds exactly one variable. Mathe- matically this is equivalent to employing linear logic, in use in LFG for semantic composition, but the method seems more practicable. While ¸-grammars could be used to formalize many approaches to grammatical theory, they are certainly natural as a basis for the formalization of LFG. This leads to a theory I would like to call ¸- LFG. In this paper it will be shown how the standard components of LFG can be set up in the framework. We will have descriptions of c-structure, descriptions of f-structure, and semantics. The di®erence between de¯ning and constraining information will be explained in terms of entailment, and requirements on long-distance paths in f- structure will be explained in terms of entailment in the presence of a simple set of axioms. 1 Introduction In this paper I want to discuss a version of Lexical-Functional Grammar (LFG) that is also a version of Categorial Grammar (CG). -
The Categorial Fine-Structure of Natural Language
1 The categorial fine-structure of natural language Johan van Benthem, Amsterdam & Stanford, March 2003 Abstract Categorial grammar analyzes linguistic syntax and semantics in terms of type theory and lambda calculus. A major attraction of this approach is its unifying power, as its basic function/ argument structures occur across the foundations of mathematics, language and computation. This paper considers, in a light example-based manner, where this elegant logical paradigm stands when confronted with the wear and tear of reality. Starting from a brief history of the Lambek tradition since the 1980s, we discuss three main issues: (a) the fit of the lambda calculus engine to characte- ristic semantic structures in natural language, (b) coexistence of the original type-theoretic and more recent modal interpretations of categorial logics, and (c) the place of categorial grammars in the total architecture of natural language, which involves mixtures of interpretation and inference. 1 From Montague Grammar to Categorial Grammar Logic and linguistics have had lively connections from Antiquity right until today (GAMUT 1991). A recurrent theme in this history is the categorial structure of language and ontology, from Aristotle's grammatical categories to Russell's theory of types in the foundations of mathematics. Further bridges were thrown as logic and linguistics developed, with Lambek 1958 as a major advance in sophistication, many years ahead of its time. Large-scale logical analysis of natural language really took off around 1970, thanks to Montague's work (Montague 1975, Partee 1997). This system connects linguistic structure and logical semantics in the following architecture. The pivotal deep structure are syntax trees formed by grammatical construction rules. -

The main aim of linguistic theory is to showhow these larger units of meaning arise out of the combination of the smaller ones. This is mo deled by means of a grammar. Computational linguistics then tries to implement this pro cess in an ecientway.Itis traditional to sub divide the task into syntax and semantics, where syntax describ es how the di erent formal elements of a textual unit, most often the sentence, can b e combined and semantics describ es how the interpretation is calculated. In most language technology applications the enco ded linguistic knowledge, i.e., the grammar, is separated from the pro cessing comp onents. The grammar consists of a lexicon, and rules that syntactically and semantically combine words and phrases into larger phrases and sentences. A variety of representation languages have b een develop ed for the enco ding of linguistic knowledge. Some of these languages are more geared towards conformity with formal linguistic theories, others are designed to facilitate certain pro cessing mo dels or sp ecialized applications. Several language technology pro ducts that are on the market to day employ annotated 109 110 Chapter 3: Language Analysis and Understanding phrase-structure grammars, grammars with several hundreds or thousands of rules describing di erent phrase typ es.

The first chapter deals with Ajdukiewicz and Bar-Hillel categorial grammars (AB grammars), their relation to context-free grammars and their learning algorithms. The second chapter is devoted to the Lambek calculus as a deductive system; the weak equivalence with context free grammars is proved; we also define the mapping from a syntactic analysis to a higher-order logical formula, which describes the seman- tics of the parsed sentence. -
An Experimental Approach to Linguistic Representation
BEHAVIORAL AND BRAIN SCIENCES (2017), Page 1 of 61 doi:10.1017/S0140525X16002028, e282 An experimental approach to linguistic representation Holly P. Branigan Department of Psychology, University of Edinburgh, Edinburgh, EH8 9JZ, United Kingdom [email protected] http://www.ed.ac.uk/profile/holly-branigan Martin J. Pickering Department of Psychology, University of Edinburgh, Edinburgh, EH8 9JZ, United Kingdom [email protected] http://www.ed.ac.uk/profile/martin-pickering Abstract: Within the cognitive sciences, most researchers assume that it is the job of linguists to investigate how language is represented, and that they do so largely by building theories based on explicit judgments about patterns of acceptability – whereas it is the task of psychologists to determine how language is processed, and that in doing so, they do not typically question the linguists’ representational assumptions. We challenge this division of labor by arguing that structural priming provides an implicit method of investigating linguistic representations that should end the current reliance on acceptability judgments. Moreover, structural priming has now reached sufficient methodological maturity to provide substantial evidence about such representations. We argue that evidence from speakers’ tendency to repeat their own and others’ structural choices supports a linguistic architecture involving a single shallow level of syntax connected to a semantic level containing information about quantification, thematic relations, and information structure, as well as to a phonological level. Many of the linguistic distinctions often used to support complex (or multilevel) syntactic structure are instead captured by semantics; however, the syntactic level includes some specification of “missing” elements that are not realized at the phonological level.
