Tackle a variety of tasks in natural language processing by learning how to use the R language and tidy data principles. This practical guide provides examples and resources to help you get up to speed with dplyr, broom, ggplot2, and other tidy tools from the R ecosystem. You’ll discover how tidy data principles can make text mining easier, more effective, and consistent by employing tools already in wide use. Text Mining with R shows you how to manipulate, summarize, and visualize the characteristics of text, sentiment analysis, tf-idf, and topic modeling. Along with tidy data methods, you’ll also examine several beginning-to-end tidy text analyses on data sources from Twitter to NASA datasets. These analyses bring together multiple text mining approaches covered in the book. Get real-world examples for implementing text mining using tidy R package Understand natural language processing concepts like sentiment analysis, tf-idf, and topic modeling Learn how to analyze unstructured, text-heavy data using R language and ecosystem

This book is intended to provide an overview for the identification and establishment of biodiversity islands. It presents examples and case studies where the biodiversity islands approach is being used in a variety of locations and contexts worldwide. It will contribute to design parameters on appropriate sizing and spatial distribution of biodiversity islands in order to be effective in conservation and regeneration across the landscape, using integrated landscape management approaches. This book is essential given the current worldwide trend of habitat destruction and the need to preserve biodiversity and its values. The chapters are organized in five sections. The first section provides the introduction. Section 2,3 and 4 discuss the challenges and alternatives of establishment and management, case studies across the globe, safeguarding of the environmental, economic, and social benefits, and the final section offers a conclusion. The contributing authors present views from the academic, the practitioner and the policymaker perspectives, offering alternatives and suggestions for promoting strategies that support biodiversity conservation through intentionally designed frameworks for sustainable forest landscapes. Readers will discover suggestions and concrete examples that can be used by a variety of stakeholders in various settings throughout the world. This book is useful to researchers, farmers, foresters, landowners, land managers, city planners, and policy makers alike.
