Download or read book An Introduction to Text Mining written by Gabe Ignatow and published by SAGE Publications. This book was released on 2017-09-22 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Students in social science courses communicate, socialize, shop, learn, and work online. When they are asked to collect data for course projects they are often drawn to social media platforms and other online sources of textual data. There are many software packages and programming languages available to help students collect data online, and there are many texts designed to help with different forms of online research, from surveys to ethnographic interviews. But there is no textbook available that teaches students how to construct a viable research project based on online sources of textual data such as newspaper archives, site user comment archives, digitized historical documents, or social media user comment archives. Gabe Ignatow and Rada F. Mihalcea's new text An Introduction to Text Mining will be a starting point for undergraduates and first-year graduate students interested in collecting and analyzing textual data from online sources, and will cover the most critical issues that students must take into consideration at all stages of their research projects, including: ethical and philosophical issues; issues related to research design; web scraping and crawling; strategic data selection; data sampling; use of specific text analysis methods; and report writing.
Download or read book The Nazis Knew My Name written by Magda Hellinger and published by Simon and Schuster. This book was released on 2022-03-15 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The “thought-provoking…must-read” (Ariana Neumann, author of When Time Stopped) memoir by a Holocaust survivor who saved an untold number of lives at Auschwitz through everyday acts of courage and kindness—in the vein of A Bookshop in Berlin and The Nazi Officer’s Wife. In March 1942, twenty-five-year-old kindergarten teacher Magda Hellinger and nearly a thousand other young women were deported as some of the first Jews to be sent to the Auschwitz concentration camp. The SS soon discovered that by putting prisoners in charge of the day-to-day accommodation blocks, they could deflect attention away from themselves. Magda was one such prisoner selected for leadership and put in charge of hundreds of women in the notorious Experimental Block 10. She found herself constantly walking a dangerously fine line: saving lives while avoiding suspicion by the SS and risking execution. Through her inner strength and shrewd survival instincts, she was able to rise above the horror and cruelty of the camps and build pivotal relationships with the women under her watch, and even some of Auschwitz’s most notorious Nazi senior officers. Based on Magda’s personal account and completed by her daughter’s extensive research, this is “an unputdownable account of resilience and the power of compassion” (Booklist) in the face of indescribable evil.

Download or read book A Preface to American Political Theory written by Donald S. Lutz and published by University Press of Kansas. This book was released on 1992-09-03 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Donald Lutz begins A Preface to American Political Theory by explaining what the book doesn't do. It doesn't begin with a panegyric to the American founding. It doesn't answer the following questions: "What are the basic principles in the U.S. Constitution? What were the intentions of the founders with respect to (fill in your own topic)? What is the meaning of pluralism, or separation of powers, or democracy, or (fill in your own concept)?" In short, it doesn't provide an overview of the content, development, or major conclusions of American political theory. What it does do is provide "a pre-theoretical analysis of how to go about studying questions like the ones above-how to conceptualize the project, how to proceed in looking for answers, how to avoid the logical traps peculiar to the study of American political theory." Lutz sets out to emancipate American political theorists from empiricism and inappropriate European theories and methadologies. The end result is to establish the foundation for the systematic study of American behavior, institutions, and ideas; to provide a general introduction to the study of American political theory; and to illustrate how textual analysis, history, empirical research, and analytic philosophy are all part of the enterprise. Designed for students and scholars in all disciplines, including political science, history, and legal studies, A Preface to American Political Theory doesn't provide answers to central continuing issues in American political theory. Rather, it provides an effective, sophisticated entree into the study of American political theory. Readers will be armed with the intellectual tools to engage in systematic study and makes them aware of the pitfalls they will inevitably encounter.

Download or read book Prose Fiction An Introduction to the Semiotics of Narrative written by Ignasi Ribó and published by Open Book Publishers. This book was released on 2019-12-13 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: This concise and highly accessible textbook outlines the principles and techniques of storytelling. It is intended as a high-school and college-level introduction to the central concepts of narrative theory – concepts that will aid students in developing their competence not only in analysing and interpreting short stories and novels, but also in writing them. This textbook prioritises clarity over intricacy of theory, equipping its readers with the necessary tools to embark on further study of literature, literary theory and creative writing. Building on a ‘semiotic model of narrative,’ it is structured around the key elements of narratological theory, with chapters on plot, setting, characterisation, and narration, as well as on language and theme – elements which are underrepresented in existing textbooks on narrative theory. The chapter on language constitutes essential reading for those students unfamiliar with rhetoric, while the chapter on theme draws together significant perspectives from contemporary critical theory (including feminism and postcolonialism). This textbook is engaging and easily navigable, with key concepts highlighted and clearly explained, both in the text and in a full glossary located at the end of the book. Throughout the textbook the reader is aided by diagrams, images, quotes from prominent theorists, and instructive examples from classical and popular short stories and novels (such as Jane Austen’s Pride and Prejudice, Franz Kafka’s ‘The Metamorphosis,’ J. K. Rowling’s Harry Potter, or Dostoyevsky’s The Brothers Karamazov, amongst many others). Prose Fiction: An Introduction to the Semiotics of Narrative can either be incorporated as the main textbook into a wider syllabus on narrative theory and creative writing, or it can be used as a supplementary reference book for readers interested in narrative fiction. The textbook is a must-read for beginning students of narratology, especially those with no or limited prior experience in this area. It is of especial relevance to English and Humanities major students in Asia, for whom it was conceived and written.
Download or read book Supervised Machine Learning for Text Analysis in R written by Emil Hvitfeldt and published by CRC Press. This book was released on 2021-10-22 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Text data is important for many domains, from healthcare to marketing to the digital humanities, but specialized approaches are necessary to create features for machine learning from language. Supervised Machine Learning for Text Analysis in R explains how to preprocess text data for modeling, train models, and evaluate model performance using tools from the tidyverse and tidymodels ecosystem. Models like these can be used to make predictions for new observations, to understand what natural language features or characteristics contribute to differences in the output, and more. If you are already familiar with the basics of predictive modeling, use the comprehensive, detailed examples in this book to extend your skills to the domain of natural language processing. This book provides practical guidance and directly applicable knowledge for data scientists and analysts who want to integrate unstructured text data into their modeling pipelines. Learn how to use text data for both regression and classification tasks, and how to apply more straightforward algorithms like regularized regression or support vector machines as well as deep learning approaches. Natural language must be dramatically transformed to be ready for computation, so we explore typical text preprocessing and feature engineering steps like tokenization and word embeddings from the ground up. These steps influence model results in ways we can measure, both in terms of model metrics and other tangible consequences such as how fair or appropriate model results are.
Download or read book Kierkegaard s Writings IX Volume 9 written by Søren Kierkegaard and published by Princeton University Press. This book was released on 2009-09-21 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prefaces was the last of four books by Søren Kierkegaard to appear within two weeks in June 1844. Three Upbuilding Discourses and Philosophical Fragments were published first, followed by The Concept of Anxiety and its companion--published on the same day--the comically ironic Prefaces. Presented as a set of prefaces without a book to follow, this work is a satire on literary life in nineteenth-century Copenhagen, a lampoon of Danish Hegelianism, and a prefiguring of Kierkegaard's final collision with Danish Christendom. Shortly after publishing Prefaces, Kierkegaard began to prepare Writing Sampler as a sequel. Writing Sampler considers the same themes taken up in Prefaces but in yet a more ironical and satirical vein. Although Writing Sampler remained unpublished during his lifetime, it is presented here as Kierkegaard originally envisioned it, in the company of Prefaces.

[CivilWarLand in Bad Decline] is scary, hilarious, and unforgettable.”—Tobias Wolff “Saunders makes the all-but-impossible look effortless.”—Jonathan Franzen “Not since Twain has America produced a satirist this funny.”—Zadie Smith “An astoundingly tuned voice—graceful, dark, authentic, and funny—telling just the kinds of stories we need to get us through these times.”—Thomas Pynchon
Download or read book Concepts of Biology written by Samantha Fowler and published by . This book was released on 2018-01-07 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.

Download or read book An Introduction to Statistical Learning written by Gareth James and published by Springer Nature. This book was released on 2023-08-01 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Introduction to Statistical Learning provides an accessible overview of the field of statistical learning, an essential toolset for making sense of the vast and complex data sets that have emerged in fields ranging from biology to finance, marketing, and astrophysics in the past twenty years. This book presents some of the most important modeling and prediction techniques, along with relevant applications. Topics include linear regression, classification, resampling methods, shrinkage approaches, tree-based methods, support vector machines, clustering, deep learning, survival analysis, multiple testing, and more. Color graphics and real-world examples are used to illustrate the methods presented. This book is targeted at statisticians and non-statisticians alike, who wish to use cutting-edge statistical learning techniques to analyze their data. Four of the authors co-wrote An Introduction to Statistical Learning, With Applications in R (ISLR), which has become a mainstay of undergraduate and graduate classrooms worldwide, as well as an important reference book for data scientists. One of the keys to its success was that each chapter contains a tutorial on implementing the analyses and methods presented in the R scientific computing environment. However, in recent years Python has become a popular language for data science, and there has been increasing demand for a Python-based alternative to ISLR. Hence, this book (ISLP) covers the same materials as ISLR but with labs implemented in Python. These labs will be useful both for Python novices, as well as experienced users.
