Machine Learning Techniques for Text

By: Nikos Tsourakis

Overview of this book

With the ever-increasing demand for machine learning and programming professionals, it's prime time to invest in the field. This book will help you in this endeavor, focusing specifically on text data and human language by steering a middle path among the various textbooks that present complicated theoretical concepts or focus disproportionately on Python code. A good metaphor this work builds upon is the relationship between an experienced craftsperson and their trainee. Based on the current problem, the former picks a tool from the toolbox, explains its utility, and puts it into action. This approach will help you to identify at least one practical use for each method or technique presented. The content unfolds in ten chapters, each discussing one specific case study. For this reason, the book is solution-oriented. It's accompanied by Python code in the form of Jupyter notebooks to help you obtain hands-on experience. A recurring pattern in the chapters of this book is helping you get some intuition on the data and then implement and contrast various solutions. By the end of this book, you'll be able to understand and apply various techniques with Python for text preprocessing, text representation, dimensionality reduction, machine learning, language modeling, visualization, and evaluation.

Generating Text in Chatbots

Cutting-edge artificial intelligence applications can now produce uncannily humanlike creations, from written essays to music and drawings. These applications are a great promise toward artificial general intelligence, to the point where machines understand or learn any intellectual task that humans can perform. Unhindered conversation with a machine has always been at the forefront of this vision. Interestingly, the most common depiction of machine intelligence in popular culture is conversational agents that can mimic human dialogs. In this chapter, we will deal with a particular type: chatbots.

Chatbots have received much hype in recent years; in this chapter, we will discuss related topics from the perspective of natural language generation. Particular emphasis is given to language modeling, which is an integral part of modern chatbot deployments. First, we will look deeper at this core component of modern natural language processing and contrast...
