Available in PDF, EPUB and Kindle. Book excerpt: Textual data contains a vast amount of information, yet for many researchers it has not been clear how the information could be used for an empirical analysis. Often times textual data are ignored or discarded in statistical analyses because regression and other statistical methods require numeric covariates. This dissertation will demonstrate how cutting-edge text mining technologies can improve empirical analyses by transforming textual data into numeric explanatory variables, thus allowing textual data to be incorporated into a statistical analysis. By transforming the textual data, the number of explanatory variables often becomes larger than the number of observations. For this reason, we explore the application of generalized additive models in tandem with adaptive lasso. In addition, we construct an algorithm for fitting a Gamma double generalized linear model with a group lasso penalty. Through this, we show how useful information can be extracted from textual data. We show how our methods can be applied through several insurance claims examples. We believe that our work can be widely used for other observational researchers in economics, business, statistical science, and social science.
Book Synopsis Supervised Machine Learning for Text Analysis in R by : Emil Hvitfeldt
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.

Book Synopsis Embeddings in Natural Language Processing by : Mohammad Taher Pilehvar
Download or read book Embeddings in Natural Language Processing written by Mohammad Taher Pilehvar and published by Morgan & Claypool Publishers. This book was released on 2020-11-13 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Embeddings have undoubtedly been one of the most influential research areas in Natural Language Processing (NLP). Encoding information into a low-dimensional vector representation, which is easily integrable in modern machine learning models, has played a central role in the development of NLP. Embedding techniques initially focused on words, but the attention soon started to shift to other forms: from graph structures, such as knowledge bases, to other types of textual content, such as sentences and documents. This book provides a high-level synthesis of the main embedding techniques in NLP, in the broad sense. The book starts by explaining conventional word vector space models and word embeddings (e.g., Word2Vec and GloVe) and then moves to other types of embeddings, such as word sense, sentence and document, and graph embeddings. The book also provides an overview of recent developments in contextualized representations (e.g., ELMo and BERT) and explains their potential in NLP. Throughout the book, the reader can find both essential information for understanding a certain topic from scratch and a broad overview of the most successful techniques developed in the literature.

This multi-purpose text can be used as an introduction to predictive models and the overall modeling process, a practitioner’s reference handbook, or as a text for advanced undergraduate or graduate level predictive modeling courses. To that end, each chapter contains problem sets to help solidify the covered concepts and uses data available in the book’s R package. This text is intended for a broad audience as both an introduction to predictive models as well as a guide to applying them. Non-mathematical readers will appreciate the intuitive explanations of the techniques while an emphasis on problem-solving with real data across a wide variety of applications will aid practitioners who wish to extend their expertise. Readers should have knowledge of basic statistical ideas, such as correlation and linear regression analysis. While the text is biased against complex equations, a mathematical background is needed for advanced topics.

Book Synopsis Leveraging Word Embeddings to Enrich Linguistics and Natural Language Understanding by : Ahmad Aljanaideh
Download or read book Leveraging Word Embeddings to Enrich Linguistics and Natural Language Understanding written by Ahmad Aljanaideh and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The availability of massive amounts of text on the internet has opened the door for building Natural Language Understanding (NLU) models for various tasks such as politeness detection and (dis)agreement detection. Word embeddings are considered essential to those models as those embeddings encode contexts in which words are used. Recent approaches in NLU have focused on using those embeddings to train complex models which optimize the classification performance of a task. The complexity of those models hinders the ability of using them to provide insight into the task at hand and to explain their decisions. We propose models that leverage word embeddings to not simply maximize classification performance but provide insight into the phenomenon/task being considered. The proposed models are driven to discover interpretable patterns from text. Those patterns can be used as features to improve the performance of explainable feature-based models. The tasks we consider include politeness detection, detecting if a conversation will derail and predicting the popularity of an opinion. We focus on the tasks of politeness detection and conversation derailment detection due to their important roles in conversations and their success. Moreover, we focus the task of predicting the popularity of an opinion as this task helps provides insight into what communities like or dislike. We illustrate how patterns discovered by the proposed models enrich linguistic analyses and in some cases help improve the performance of feature-based models of those tasks. We also propose a model for predicting distributions over annotations for the task of (dis)agreement detection as in an effort to provide more insight to how language could be interpreted by different listeners. Leveraging word embeddings to build models that are driven to provide insight into data can help expand the applicability of NLU models from simply making decisions to helping practitioners in learning about the task/phenomenon they are studying. Explainable models can help applications where it is important to obtain an explanation on how the model reached its decision. One example is automatically providing feed-back to forum users on why they where banned. Making Artificial Intelligence models (AI) more insightful, interpretable and explainable can enhance our trust of AI in general and encourage more practitioners to use it for their applications.
