An introduction to information retrieval, the foundation for modern search engines, that emphasizes implementation and experimentation. Information retrieval is the foundation for modern search engines. This textbook offers an introduction to the core topics underlying modern search technologies, including algorithms, data structures, indexing, retrieval, and evaluation. The emphasis is on implementation and experimentation; each chapter includes exercises and suggestions for student projects. Wumpus—a multiuser open-source information retrieval system developed by one of the authors and available online—provides model implementations and a basis for student work. The modular structure of the book allows instructors to use it in a variety of graduate-level courses, including courses taught from a database systems perspective, traditional information retrieval courses with a focus on IR theory, and courses covering the basics of Web retrieval. In addition to its classroom use, Information Retrieval will be a valuable reference for professionals in computer science, computer engineering, and software engineering.

One kiss could be enough to kill in the first book in the fan-favorite Dark Elements trilogy, from the #1 New York Times bestselling author of the Blood and Ash series. Seventeen-year-old Layla just wants to be normal—fit in at school and go out on a real date with the gorgeous Zayne, who she's crushed on since forever. Trouble is, Zayne treats Layla like a sister—and Layla is anything but normal. She's half demon, half gargoyle, with abilities no one else possesses. And even though Zayne is a Warden, part of the race of gargoyles tasked with hunting demons and keeping humanity safe, Layla's kiss will kill anything with a soul—including him. Then she meets Roth—a tattooed, sinfully hot demon who claims to know her secrets. Though Layla knows she should stay away, it’s tough when that whole no-kissing thing isn't an issue. Trusting Roth could ruin her chances with Zayne—and brand her a traitor to the Warden family that raised her. But as Layla discovers she's the sole reason for a violent demon uprising, kissing the enemy suddenly pales in comparison to the looming end of the world. The Dark Elements Book 1: White Hot Kiss Book 2: Stone Cold Touch Book 3: Every Last Breath

WHAT VALUABLE COMPANY IS NOBODY BUILDING? The next Bill Gates will not build an operating system. The next Larry Page or Sergey Brin won’t make a search engine. If you are copying these guys, you aren’t learning from them. It’s easier to copy a model than to make something new: doing what we already know how to do takes the world from 1 to n, adding more of something familiar. Every new creation goes from 0 to 1. This book is about how to get there. ‘Peter Thiel has built multiple breakthrough companies, and Zero to One shows how.’ ELON MUSK, CEO of SpaceX and Tesla ‘This book delivers completely new and refreshing ideas on how to create value in the world.’ MARK ZUCKERBERG, CEO of Facebook ‘When a risk taker writes a book, read it. In the case of Peter Thiel, read it twice. Or, to be safe, three times. This is a classic.’ NASSIM NICHOLAS TALEB, author of The Black Swan

Bill Bryson's biography of William Shakespeare unravels the superstitions, academic discoveries and myths surrounding the life of our greatest poet and playwright. Ever since he took the theatre of Elizabethan London by storm over 400 years ago, Shakespeare has remained centre stage. His fame stems not only from his plays - performed everywhere from school halls to the world's most illustrious theatres - but also from his enigmatic persona. His face is familiar to all, yet in reality very little is known about the man behind the masterpieces. Shakespeare's life, despite the scrutiny of generations of biographers and scholars, is still a thicket of myths and traditions, some preposterous, some conflicting, arranged around the few scant facts known about the Bard - from his birth in Stratford to the bequest of his second best bed to his wife when he died. Taking us on a journey through the streets of Elizabethan and Jacobean England, Bryson examines centuries of stories, half-truths and downright lies surrounding our greatest dramatist. With a steady hand and his trademark wit, he introduces a host of engaging characters, as he celebrates the magic of Shakespeare's language and delights in details of the bard's life, folios, poetry and plays.

The purpose of authority control is to ensure consistency in representing a value - a name of a person, a place name, or a term or code representing a subject - in the elements used as access points in information retrieval. The primary purpose of this study is to produce a framework that will provide a clearly stated and commonly shared understanding of what the subject authority data/record/file aims to provide information about, and the expectation of what such data should achieve in terms of answering user needs.

Computer games, the Internet, and other new communications media are often seen to pose threats and dangers to young people, but they also provide new opportunities for creativity and self-determination. As we start to look beyond the immediate hopes and fears that new technologies often provoke, there is a growing need for in-depth empirical research. Digital Generations presents a range of exciting and challenging new work on children, young people, and new digital media. The book is organized around four key themes: Play and Gaming, The Internet, Identities and Communities Online, and Learning and Education. The book brings together researchers from a range of academic disciplines – including media and cultural studies, anthropology, sociology, psychology and education – and will be of interest to a wide readership of researchers, students, practitioners in digital media, and educators.
