A mainstay of functional linguistics has been the claim that linguistic elements and patterns that are frequently used in discourse become conventionalized as grammar. This book addresses the two issues that are basic to this claim: first, the question of what types of elements are frequently used in discourse and second, the question of how frequency of use affects cognitive representations. Reporting on evidence from natural conversation, diachronic change, variability, child language acquisition and psycholinguistic experimentation the original articles in this book support two major principles. First, the content of people s interactions consists of a preponderance of subjective, evaluative statements, dominated by the use of pronouns, copulas and intransitive clauses. Second, the frequency with which certain items and strings of items are used has a profound influence on the way language is broken up into chunks in memory storage, the way such chunks are related to other stored material and the ease with which they are accessed to produce new utterances.

Re-examines frequency, entrenchment and salience, three foundational concepts in usage-based linguistics, through the prism of learning, memory, and attention.

The book addresses a controversial current topic in language acquisition studies: the impact of frequency on linguistic structure in child language. A major strength of the book is that the role of input frequency in the acquisition process is evaluated in a large variety of languages, topics and the two major theoretical frameworks: UG-based and usage-based accounts. While most papers report a clear frequency effect, different factors that may be interacting with pure statistical effects are critically assessed. An introductory statement is made by Thomas Roeper who calls for caution as he identifies frequency as a non-coherent concept and argues for a precise definition of what can and cannot be explained by statistical effects.

This book proposes that subjective expression shapes grammatical and lexical patterning in American English conversation. Analyses of structural and functional properties of English conversational utterances indicate that the most frequent combinations of subject, tense, and verb type are those that are used by speakers to personalize their contributions, not to present unmediated descriptions of the world. These findings are informed by current research and practices in linguistics which argue that the emergence, or conventionalization, of linguistic structure is related to the frequency with which speakers use expressions in discourse. The use of conversational data in grammatical analysis illustrates the local and contingent nature of grammar in use and also raises theoretical questions concerning the coherence of linguistic categories, the viability of maintaining a distinction between semantic and pragmatic meaning in analytical practice, and the structural and social interplay of speaker point of view and participant interaction in discourse.

Provides a dynamic network model of grammar that explains how linguistic structure is shaped by language use.

The present book finds and collects absolutely new aspects of word frequency. First, eminent characteristics (such as the h-point, first used in scientometrics, the k-, m-, and n-points) are introduced - it can be shown that the geometry of word frequency is fundamentally based on them. Furthermore, various indicators of text properties are proposed for the first time, such as thematic concentration, autosemantic text compactness, autosemantic density, etc. In detail, the autosemantic structure of a given text is evaluated by means of a graph representation and its properties (according to a problem from network research). Special emphasis is given to the part-of-speech differentiation, which plays a significant role in stylistics. On the basis of a general theory, which has been developed especially for linguistic research, problems of the frequency structure of texts with respect to word occurrence are investigated and discussed in detail. Methodologically, specific reference is made to synergetic linguistics, including some exemplary analyses, showing that there are points of contact with this field. A separate chapter is dedicated to within-sentence word position; this issue considers grammar as well as language genesis; another chapter is dedicated to the type-token ratio, discussing all established methods and their relevance for word frequency analysis. All methods presented in the book are statistically tested; to this end, some new tests have been developed. All procedures and calculations are conducted for 20 languages, ranging from Polynesia, Indonesia, India, and Europe to a North American Indian language. The broad distribution of the data and texts from all genres allows generalizations with respect to language typology.

This book is the first to provide a comprehensive survey of the computational models and methodologies used for studying the evolution and origin of language and communication. Comprising contributions from the most influential figures in the field, it presents and summarises the state-of-the-art in computational approaches to language evolution, and highlights new lines of development. Essential reading for researchers and students in the fields of evolutionary and adaptive systems, language evolution modelling and linguistics, it will also be of interest to researchers working on applications of neural networks to language problems. Furthermore, due to the fact that language evolution models use multi-agent methodologies, it will also be of great interest to computer scientists working on multi-agent systems, robotics and internet agents.
