Why this book

The literature on AI splits between the critique of the hype and the practical manual, and says little about the distance between what AI can do and what reaches the user ready to use. The book offers a method for closing that distance before, during and after each use: choose the tool by the type of work, structure and anchor requests in sources, and validate every result.

Other books say what AI can do; this one says when it's better with it.

"The purpose of this book is to guide professionals in applying Artificial Intelligence (AI) technologies with rigor, responsibility and method in their work of generating and applying knowledge."
