The purpose of this book is to study the development of computational corpus linguistics to discuss its design, use, and implementation. The work intends to demonstrate the remarkable ease with which the functionalities needed in a corpus system can be implemented, when based upon adequate means of representing, querying, and reasoning. Apart from being interesting from a theoretical point of view, the practical aspects of corpus linguistics are highlighted, too: as the proof of the pudding is in the eating, the book also includes the implementation of corpora in action by comparing the definition of paparazzo' gained on the first hand from dictionaries, on the second hand from the databases presented by corpora, while on the third hand from corpus data issued by media releases. The author, throughout her studies - Physics, English language, and Law - has always shown particular interest in words: their meaning, context and the effect they make on public mind - since the rightselection of words may deter, or contrariwise, encourage audience to go on listening/reading. Just like in case of texts appearing on covers of books..
