Book Description
Class-tested and coherent, this textbook teaches classical and web information retrieval, including web search and the related areas of text classification and text clustering from basic concepts. It gives an up-to-date treatment of all aspects of the design and implementation of systems for gathering, indexing, and searching documents; methods for evaluating systems; and an introduction to the use of machine learning methods on text collections. All the important ideas are explained using examples and figures, making it perfect for introductory courses in information retrieval for advanced undergraduates and graduate students in computer science. Based on feedback from extensive classroom experience, the book has been carefully structured in order to make teaching more natural and effective. Slides and additional exercises (with solutions for lecturers) are also available through the book's supporting website to help course instructors prepare their lectures.

Book Description
From the #1 bestselling author of The Bomber Mafia, the landmark book that has revolutionized the way we understand leadership and decision making. In his breakthrough bestseller The Tipping Point, Malcolm Gladwell redefined how we understand the world around us. Now, in Blink, he revolutionizes the way we understand the world within. Blink is a book about how we think without thinking, about choices that seem to be made in an instant--in the blink of an eye--that actually aren't as simple as they seem. Why are some people brilliant decision makers, while others are consistently inept? Why do some people follow their instincts and win, while others end up stumbling into error? How do our brains really work--in the office, in the classroom, in the kitchen, and in the bedroom? And why are the best decisions often those that are impossible to explain to others? In Blink we meet the psychologist who has learned to predict whether a marriage will last, based on a few minutes of observing a couple; the tennis coach who knows when a player will double-fault before the racket even makes contact with the ball; the antiquities experts who recognize a fake at a glance. Here, too, are great failures of "blink": the election of Warren Harding; "New Coke"; and the shooting of Amadou Diallo by police. Blink reveals that great decision makers aren't those who process the most information or spend the most time deliberating, but those who have perfected the art of "thin-slicing"--filtering the very few factors that matter from an overwhelming number of variables.

Book Description
"The 2012 report recognized that expanding women's agency - their ability to make decisions and take advantage of opportunities is key to improving their lives as well as the world. This report represents a major advance in global knowledge on this critical front. The vast data and thousands of surveys distilled in this report cast important light on the nature of constraints women and girls continue to face globally. This report identifies promising opportunities and entry points for lasting transformation, such as interventions that reach across sectors and include life-skills training, sexual and reproductive health education, conditional cash transfers, and mentoring. It finds that addressing what the World Health Organization has identified as an epidemic of violence against women means sharply scaling up engagement with men and boys. The report also underlines the vital role information and communication technologies can play in amplifying women's voices, expanding their economic and learning opportunities, and broadening their views and aspirations. The World Bank Group's twin goals of ending extreme poverty and boosting shared prosperity demand no less than the full and equal participation of women and men, girls and boys, around the world." -- Publisher's description.

""Free Culture goes beyond illuminating the catastrophe to our culture of increasing regulation to show examples of how we can make a different future. These new-style heroes and examples are rooted in the traditions of the founding fathers in ways that seem obvious after reading this book. Recommended reading to those trying to unravel the shrill hype around 'intellectual property.'"" - Brewster Kahle, founder of the Internet Archive.

Book Description
“If you are curious and open to the life around you, if you are troubled as to why, how and by whom political power is held and used, if you sense there must be good intellectual reasons for your unease, if your curiosity and openness drive you toward wishing to act with others, to ‘do something,’ you already have much in common with the writers of the three essays in this book.” — Adrienne Rich With a preface by Adrienne Rich, Manifesto presents the radical vision of four famous young rebels: Marx and Engels’ Communist Manifesto, Rosa Luxemburg’s Reform or Revolution and Che Guevara’s Socialism and Humanity.
