Analyzes different kinds of reformulations used in information retrieval systems where full text databases are accessed through natural language queries. Tests of these reformulations on large full text databases managed by the Syntactic and Probabilistic Indexing and Retrieval of Information in Texts (SPIRIT) system are described, and an expert…

Describes SCISOR (System for Conceptual Information Summarization, Organization and Retrieval), a prototype intelligent information retrieval system that extracts useful information from large bodies of text. It overcomes limitations of linguistic coverage by applying a text processing strategy that is tolerant of unknown words and gaps in…

Summarizes a range of theoretical approaches to language acquisition. Argues that language representations emerge from interactions at all levels from brain to society. Connectionism, which provides a set of computational tools for exploring the conditions under which emergent properties arise, is discussed, and simulations of emergence of…

Pinpoints specificities of computer-aided corpus-based work in foreign language pedagogic contexts and assesses how they can feed into language teaching and learning practices generally, despite the ostensible pedagogic and processing shortcomings of corpus-based work in these kinds of contexts. (Author/VWL)

Presents a new dimension of lexical variation--contextual distinctiveness. CD is a corpus-derived summary measure of the frequency distribution of the contexts in which a word occurs, and it is naturally compatible with contextual theories of semantic representation and meaning. An experiment shows that CD is a better predictor of lexical decision…

The author replies to a critique a paper he wrote on defining applied linguistics as a field of inquiry and the extent to which corpus analysis can properly inform its practices. (Author/VWL)

This paper surveys work on applying the insights of lexicalized grammars to low-level discourse, to show the value of positing an autonomous grammar for low-level discourse in which words (or idiomatic phrases) are associated with discourse-level predicate-argument structures or modification structures that convey their syntactic-semantic meaning…

The distinction between singular and plural enters into linguistic phenomena such as morphology, lexical semantics, and agreement and also must interface with perceptual and conceptual systems that assess numerosity in the world. Three experiments examine the computation of semantic number for singulars and plurals from the morphological…

The target article represents a significant advance in the level of sophistication applied to models of bilingual word recognition, and Dijkstra and van Heuven are to be congratulated on this endeavour. Bearing in mind the success of the (computational) BIA model in capturing detailed patterns of experimental data, I look forward to future…

Dramatic advances in personal computer technology have given language teachers access to vast quantities of machine-readable text, which can be analyzed with a view toward improving the basis of language instruction. Corpus linguistics provides analytic techniques and practical tools for studying language in use. This volume includes both an…

Within child language acquisition research, there has been a fair amount of controversy regarding children's knowledge of the grammatical properties associated with verbal inflection (e.g., tense, agreement, and aspect). Some researchers have proposed that the child's early grammar is fundamentally different from the adult grammar, whereas others…

Colloquial Singapore English is an outer circle variety that exhibits contact induced linguistic change. It has been characterized as the L variant in diglossic opposition to standard English. In this paper, the authors address two related issues: (1) the extent to which the Singapore English diglossia is supported by corpus data, and (2) the…

This article has two goals: to report on the trialling of fourteen 1,000 word-family lists made from the British National Corpus, and to use these lists to see what vocabulary size is needed for unassisted comprehension of written and spoken English. The trialling showed that the lists were properly sequenced and there were no glaring omissions…

This study investigates whether second language (L2) phonological learning can be characterized as a gradual and systematically patterned replacement of nonnative segments by native segments in learners' speech, conforming to a two-stage implicational scale. We adopt a dynamic approach to language variation based on Gatbonton's (1975, 1978)…

Corpora have been used for pedagogical purposes for more than two decades but empirical studies are relatively rare, particularly in the context of grammar teaching. The present study focuses on students' attitudes towards grammar and how these attitudes are affected by the introduction of concordancing. The principal aims of the project were to…
