This paper presents a novel approach to the unsupervised learning of syntactic analyses of natural language text. Most previous work has focused on maximizing likelihood according to generative PCFG models. In contrast, we employ a simpler probabilistic model over trees based directly on constituent identity and linear context, and use an EM-like iterative procedure to induce structure. This method produces much higher quality analyses, giving the best published results on the ATIS dataset.

Stephen Mulhall offers a new way of interpreting one of the most famous and contested texts in modern philosophy: remarks on "private language" in Wittgenstein's Philosophical Investigations. He sheds new light on a central controversy concerning Wittgenstein's early work by showing its relevance to a proper understanding of the later work.

Taking as its starting point significant similarities between a formal language model—Grammar Systems—and a grammatical theory—Autolexical Syntax—in this paper we suggest the application of the former to the topic of the latter. To show the applicability of Grammar Systems Theory to grammatical description, we introduce a formal-language-theoretic framework for the architecture of natural language grammar: Linguistic Grammar Systems. We prove the adequacy of this model by highlighting its features (modularity, parallelism, interaction) and by showing the similarity between (...) this framework and accepted and well-known grammatical models (e.g. Autolexical Syntax).

The primary concern of Stephen Mulhall's book is to investigate an interpretation of Wittgenstein's remarks on private language, associated paradigmatically with Norman Malcolm. On this reading, the grammar of our ordinary concepts of language, reference, meaning, rule, etc. is held to prohibit or exclude the idea of a private language. The attempt to give expression to the idea is held to result in a violation of the grammar of these concepts, which connects them essentially with the idea (...) of public criteria that are accepted as establishing that a word has been correctly used. Something that philosophers have been inclined to regard as a possibility is shown to be excluded: the attempt to describe it results in .. (shrink)

Universal Grammar (UG) is a theory about the innate linguistic knowledge that child language learners bring to the task of language acquisition. This chapter examines the findings of experimental research on children's knowledge of one principle of UG, called Principle C. It presents the defining properties of Principle C. The chapter reviews empirical evidence showing that children apply Principle C to a range of disparate‐looking phenomena. It also presents empirical findings that document children's assignment of hierarchical structure to (...) strings of words. The empirical evidence supports a conclusion – that child language learners access a level of linguistic representation in addition to the constituent structure that is formed using Merge. This additional component of the language apparatus is called Logical Form. The chapter looks at a string of words where Principle C applies at the level of Logical Form. Cleft sentences are one such case. (shrink)

This book argues that language is a network of concepts which in turn is part of the general cognitive network of the mind. It challenges the widely-held view that language is an innate mental module with its own special internal organization. It shows that language has the same internal organization as other areas of knowledge such as social relations and action schemas, and reveals the rich links between linguistic elements and contextual categories. Professor Hudson presents a new (...) theory of how we learn and use our knowledge of language. He puts this to work in a series of extended explorations of morphology, syntax, semantics, and sociolinguistics. Every step of his argument and exposition is illustrated with examples, including the kind mainstream theory finds it hard to analyse. He introduces the latest version of his influential theory of Word Grammar and shows how it can be used to explain the operations of language and as a key to understanding the associated operations of the mind.

Using an asymptotic characterization of probabilistic finite state languages over a one-letter alphabet we construct a probabilistic language with regular support that cannot be generated by probabilistic CFGs. Since all probability values used in the example are rational, our work is immune to the criticism leveled by Suppes (Synthese 22:95–116, 1970 ) against the work of Ellis ( 1969 ) who first constructed probabilistic FSLs that admit no probabilistic FSGs. Some implications for probabilistic language modeling by HMMs are (...) discussed. (shrink)

Traditional grammar and current theoretical approaches towards modelling grammatical knowledge ignore language in interaction: that is, words such as huh, eh, yup or yessssss. This groundbreaking book addresses this gap by providing the first in-depth overview of approaches towards interactional language across different frameworks and linguistic sub-disciplines. Based on the insights that emerge, a formal framework is developed to discover and compare language in interaction across different languages: the interactional spine hypothesis. Two case-studies are presented: confirmationals and (...) response markers, both of which show evidence for systematic grammatical knowledge. Assuming that language in interaction is regulated by grammatical knowledge sheds new light on old questions concerning the relation between language and thought and the relation between language and communication. It is essential reading for anyone interested in the relation between language, cognition and social interaction. (shrink)

Already hailed as a masterpiece, Foundations of Language offers a brilliant overhaul of the last thirty-five years of research in generative linguistics and related fields. "Few books really deserve the cliché 'this should be read by every researcher in the field'," writes Steven Pinker, author of The Language Instinct, "but Ray Jackendoff's Foundations of Language does." Foundations of Language offers a radically new understanding of how language, the brain, and perception intermesh. The book renews the (...) promise of early generative linguistics: that language can be a valuable entrée into understanding the human mind and brain. The approach is remarkably interdisciplinary. Behind its innovations is Jackendoff's fundamental proposal that the creativity of language derives from multiple parallel generative systems linked by interface components. This shift in basic architecture makes possible a radical reconception of mental grammar and how it is learned. As a consequence, Jackendoff is able to reintegrate linguistics with philosophy of mind, cognitive and developmental psychology, evolutionary biology, neuroscience, and computational linguistics. Among the major topics treated are language processing, the relation of language to perception, the innateness of language, and the evolution of the language capacity, as well as more standard issues in linguistic theory such as the roles of syntax and the lexicon. In addition, Jackendoff offers a sophisticated theory of semantics that incorporates insights from philosophy of language, logic and formal semantics, lexical semantics of various stripes, cognitive grammar, psycholinguistic and neurolinguistic approaches, and the author's own conceptual semantics.

The goal of this study is to reintegrate the theory of generative grammar into the cognitive sciences. Generative grammar was right to focus on the child's acquisition of language as its central problem, leading to the hypothesis of an innate Universal Grammar. However, generative grammar was mistaken in assuming that the syntactic component is the sole course of combinatoriality, and that everything else is “interpretive.” The proper approach is a parallel architecture, in which phonology, syntax, and semantics are autonomous (...) generative systems linked by interface components. The parallel architecture leads to an integration within linguistics, and to a far better integration with the rest of cognitive neuroscience. It fits naturally into the larger architecture of the mind/brain and permits a properly mentalistic theory of semantics. It results in a view of linguistic performance in which the rules of grammar are directly involved in processing. Finally, it leads to a natural account of the incremental evolution of the language capacity. Key Words: evolution of language; generative grammar; parallel architecture; semantics; syntax. (shrink)

In recent years, the study of formal semantics and formal pragmatics has grown tremendously showing that core aspects of language meaning can be explained by a few principles. These principles are grounded in the logic that is behind - and tightly intertwined with - the grammar of human language. In this book, some of the most prominent figures in linguistics, including Noam Chomsky and Barbara H. Partee, offer new insights into the nature of linguistic meaning and pave the (...) way for the further development of formal semantics and formal pragmatics. Each chapter investigates various dimensions in which the logical nature of human language manifests itself within a language and/or across languages. Phenomena like bare plurals, free choice items, scalar implicatures, intervention effects, and logical operators are investigated in depth and at times cross-linguistically and/or experimentally. This volume will be of interest to scholars working within the fields of semantics, pragmatics, language acquisition and psycholinguistics. (shrink)

This book is a collection of essays, weaving together cognitive psychology, psycho-linguistics, developmental psychology, modern philosophy and behavioural sciences. It raises the question, how grammar relates to our remarkable ability to cooperate for future needs and how our thought process is related to grammatical parameters.

The scope and audacity of Bhaṭṭoji Dīkṣita’s contributions to Sanskrit grammar has made him one of early-modern India’s most influential, if not controversial, intellectuals. Yet for as consequential as Bhaṭṭoji’s has been for histories of early-modern scholasticism, his extensive corpus of non-grammatical writings has attracted relatively little scholarly attention. This paper examines Bhaṭṭoji’s work on Vedānta, the Tattvakaustubha, in order to gage how issues of language became an increasingly important site of inter-religious critique among early-modern Vedāntins. In the Tattvakaustubha, (...) Bhaṭṭoji reproaches Madhvācārya, the founder of the eponymous Mādhva or Dvaita Vedānta system, for his use of ungrammatical words. In extending his accusations of grammatical negligence to include Madhva’s early commentator Jayatīrtha, Bhaṭṭoji sought to undermine Mādhva claims to authoritative scriptural exegesis. Bhaṭṭoji’s provocation impelled later Mādhva scholars like Rāghavendratīrtha to bring a sharper set of grammatical tools to core commentarial works. Where others have pointed to Vyāsatīrtha as a turning point for Mādhva scholastic discourse in the areas of Pūrva Mīmāṃsā and Navya Nyāya, this paper suggests that it was the post-Bhaṭṭoji scholar Rāghavendratīrtha who brought a hitherto unrivaled grammatical expertise to Mādhva writings. That both Mādhva and Advaita Vedāntins wielded grammatical legitimacy as a cudgel against the other raises important socio-historical questions about the relationship between text-criticism, conceptions of scholastic legitimacy, and inter-religious contestation in early-modern South Asia.

This paper continues a conversation about Wittgenstein’s picture of language and meaning and its potential applications for educational theorising. It takes the form of a response to Wolff-Michael Roth’s earlier paper “Heeding Wittgenstein on “understanding” and “meaning”: A pragmatist and concrete human psychological approach in/for education,” in which Roth problematizes the use of the terms “understanding” and “meaning” in education discourse and proposes their abandonment. Whilst we agree with Roth about a series of central points, at the same time (...) we maintain that he has taken his argument in directions antithetical to our reading of Wittgenstein’s work. We offer four points of departure, exploring themes of: appropriate questioning; eliminativism; language-games and grammar; and productivity, explanation, and a science of learning. We conclude by discussing ways consistent with Wittgenstein’s thought to go on in thinking about education. (shrink)

Although the two volumes of _Logic, Language, and Meaning _can be used independently of one another, together they provide a comprehensive overview of modern logic as it is used as a tool in the analysis of natural language. Both volumes provide exercises and their solutions.

We develop an approach to automatically identify the most probable multiword constructions used in children’s utterances, given syntactically annotated utterances from the Brown corpus of CHILDES. The found constructions cover many interesting linguistic phenomena from the language acquisition literature and show a progression from very concrete toward abstract constructions. We show quantitatively that for all children of the Brown corpus grammatical abstraction, defined as the relative number of variable slots in the productive units of their grammar, increases globally with (...) age.

While rules and exemplars are usually viewed as opposites, this paper argues that they form end points of the same distribution. By representing both rules and exemplars as (partial) trees, we can take into account the fluid middle ground between the two extremes. This insight is the starting point for a new theory of language learning that is based on the following idea: If a language learner does not know which phrase‐structure trees should be assigned to initial sentences, (...) s/he allows (implicitly) for all possible trees and lets linguistic experience decide which is the “best” tree for each sentence. The best tree is obtained by maximizing “structural analogy” between a sentence and previous sentences, which is formalized by the most probable shortest combination of subtrees from all trees of previous sentences. Corpus‐based experiments with this model on the Penn Treebank and the Childes database indicate that it can learn both exemplar‐based and rule‐based aspects of language, ranging from phrasal verbs to auxiliary fronting. By having learned the syntactic structures of sentences, we have also learned the grammar implicit in these structures, which can in turn be used to produce new sentences. We show that our model mimicks children’s language development from item‐based constructions to abstract constructions, and that the model can simulate some of the errors made by children in producing complex questions.

Dewey proposed a new theory of language, in which the form (such as symbols) and content of language are not separated. The content of language includes the physical aspects of the world, which are purely quantitative: the life process, which involves functional responses to qualities, and the human life process, which involves the conscious integration of the potentiality of qualities to form a functional whole. The pinnacle of this process is individuality, or the emergence of a unique (...) function to change social habits through a democratic process. However, there is a real danger that the form and content of language become split. To prevent such a split, Dewey proposed education through the basic occupations of the production of food, clothing and shelter. (shrink)

We introduce a set of biologically and computationally motivated design choices for modeling the learning of language, or of other types of sequential, hierarchically structured experience and behavior, and describe an implemented system that conforms to these choices and is capable of unsupervised learning from raw natural-language corpora. Given a stream of linguistic input, our model incrementally learns a grammar that captures its statistical patterns, which can then be used to parse or generate new data. The grammar constructed (...) in this manner takes the form of a directed weighted graph, whose nodes are recursively (hierarchically) defined patterns over the elements of the input stream. We evaluated the model in seventeen experiments, grouped into five studies, which examined, respectively, (a) the generative ability of grammar learned from a corpus of natural language, (b) the characteristics of the learned representation, (c) sequence segmentation and chunking, (d) artificial grammar learning, and (e) certain types of structure dependence. The model's performance largely vindicates our design choices, suggesting that progress in modeling language acquisition can be made on a broad front—ranging from issues of generativity to the replication of human experimental findings—by bringing biological and computational considerations, as well as lessons from prior efforts, to bear on the modeling approach.

The target article advanced the null, unified and widely misinterpreted generative hypothesis regarding second language (L2) acquisition. Postulating that UG (Universal Grammar) constrains L2 knowledge growth does not entail identical developmental trajectories for L2 and first language (LI) acquisition; nor does it preclude a role for the L1. In embracing this hypothesis, we maintain a distinction between competence and performance. Those who conflate the two repeat fundamental and by no means unprecedented misconstruals of the generative enterprise, and more (...) specifically, of the empirical content of the null hypothesis regarding L2 linguistic knowledge growth. We hope to have identified certain common goals, the adoption of which might constitute a firm foundation for continued productive interdisciplinary development of contemporary theoretical and experimental L2 acquisition research.

We started from the fact that type theory, in the way it was implemented in IL, makes it costly to deal with nominalization processes. We have also argued that the type hierarchy as such doesn't play any real role in a grammar; the classification it provides for different semantic objects is already contained, in some sense, in the categorial structure of the grammar itself. So, on the basis of a theory of properties (Cocchiarella's HST*) we have tried to build a (...) language (IL*) whose syntax does not contain any explicit typing of expressions. Some of the consequences that this move brings about in the overall organization of the grammar can be summarized as follows:it allows for a simple treatment of infinitives, gerunds, factives and, in general, all those phenomena which might be analyzed as cases of nominalization;it provides a simpler and more constrained semantics than IL, since IL* doesn't go beyond second order, and its non-modal basis is axiomatizable;it suggests that the role of logical form in a theory of grammar could be that of a family of theories of semantic objects;it eliminates the extrinsic limitations of a type hierarchy on the choice of the system of syntactic categories.I think that it is interesting to notice how having an explicit semantic framework helps to provide a sense in which it is legitimate to regard the syntax of a language as ‘autonomous’.

Sound and Grammar: A Neo-Sapirian Theory of Language by Susan F. Schmerling offers an original overall linguistic theory based on the work of the early American linguist Edward Sapir, supplemented with ideas from the philosopher-logicians Kazimierz Ajdukiewicz and Richard Montague and the linguist Elisabeth Selkirk. The theory yields an improved understanding of interactions among different aspects of linguistic structure, resolving notorious issues directly inherited by current theory from (post- ) Bloomfieldian linguistics. In the theory presented here, syntax is a (...) filter on a phonological algebra, not a linguistic level; linguistic expressions are phonological structures, and syntax is semantically relevant relations among phonological structures. The book shows how Neo-Sapirian grammar sheds new light on syntax-phonology interactions in English, German, French, and Spanish. (shrink)

The current conception of the relation between UG and the grammar of a language rules out the no-access hypothesis, but does not distinguish between the full-access and partial-access hypotheses. The former raises the issue of why language acquisition in child and adult should be so different. The evidence presented in Epstein et al.'s target article seems inconclusive regarding a choice between hypotheses.

This paper introduces a novel perspective on Agentive Cognitive Construction Grammar (AgCCxG) by examining the intricate interplay between mind and language through the lens of both Active Inference and Peircean semiotics. AgCCxG emphasizes the impact of intention and purpose on linguistic choices as a cognitive imperative to balance the symbolic Self (Intelligent Agent) with the dynamics of the environment. Among other things, the paper posits that linguistic constructions, particularly Constructional Attachment Patterns (CAPs), like argument structure constructions, embody experienced interactions (...) with the world through reenactment routines via the integration of multisensory channels. Unlike traditional usage-based approaches (e.g., construction grammars), AgCCxG embraces a robust theory of signs that reveals human representation as a continuous process of semiotic hybridization for the creative prediction of uncertain scenarios. Importantly, the paper challenges the notion of the mind as a unified, rational, uncertainty-reducing machine by asserting that physical processes governing open biological systems profoundly influence the linguistic sign system. Intelligent agents’ adaptability in expressing incongruous realities thus highlights the role of semiotic hybridization in preserving an agent’s autonomy and semiotic boundary. (shrink)

To clarify Wittgenstein's status as an analytic philosopher, we must study his use of the expressions 'language', 'grammar', etc. We tend to take 'language' as an abstract mass-noun and to generalize quite specific remarks. We overlook the possibility of taking 'our grammar' to refer to our particular description of the use of words rather than to what we describe. Preserving the ambiguity of 'Sprache' between language and speech calls for a neutral translation, e.g. 'what we say'. Wittgenstein's (...) 'descriptions of the grammar of our language' are more varied and purpose-specific than usually recognized. (shrink)
