"The main focus of this book is the investigation of linguistic variation in Spanish, considering spoken and written, specialised and non-specialised registers from a corpus linguistics approach and employing computational updated tools. The ten chapters represent a range of research on Spanish using a number of different corpora drawn from, amongst others, academic manuals, research articles, student writings, formal conversations, spoken casual interactions, and technical reports. A variety of methodologies are brought to bear upon these corpora including multi-dimensional and multi-register analysis, latent semantic analysis and lexical bundles."--book jacket.
