"I find this book very useful, as predictive modelling with text is
an important field in data science and statistics, and yet the one
that has been consistently under-represented in technical
literature. Given the growing volume, complexity and accessibility
of unstructured data sources, as well as the rapid development of
NLP algorithms, knowledge and skills in this domain is in
increasing demand. In particular, there’s a demand for pragmatic
guidelines that offer not just the theoretical background to the
NLP issues but also explain the end-to-end modelling process and
good practices supported with code examples, just like "Supervised
Machine Learning for Text Analysis in R" does. Data scientists and
computational linguists would be a prime audience for this kind of
publication and would most likely use it as both, (coding)
reference and a textbook."
~Kasia Kulma, data science consultant"This book fills a critical
gap between the plethora of text mining books (even in R) that are
too basic for practical use and the more complex text mining books
that are not accessible to most data scientists. In addition, this
book uses statistical techniques to do text mining and text
prediction and classification. Not all text mining books take this
approach, and given the level of this book, it is one of its
strongest features."
~Carol Haney, Quatrics"This book would be valuable for advanced
undergraduates and early PhD students in a wide range of areas that
have started using text as data…The main strength of the book is
its connection to the tidyverse environment in R. It's relatively
easy to pick up and do powerful things."
~David Mimno, Cornell University"The authors do a great job of
presenting R programmers a variety of deep learning applications to
text-based problems. Perhaps one of the best parts of this book is
the section on interpretability, where the authors showcase methods
to diagnose features on which these complex models rely to make
their prediction. Considering how important the area of
interpretability is to natural language processing research and is
often skipped in applied textbooks, the authors should be commended
for incorporating it in this book."
~Kanishka Misra, Purdue University"In conclusion, the presented
book is extremely useful for graduate students, advanced
researchers, and practitioners of statistics and data science who
are interested in learning cutting-edge supervised ML techniques
for text data. By utilizing the tidyverse environment and providing
easy-to-understand R code examples with detailed study cases of
real-world text mining problems, this book stands out and is a
worthwhile read."
-Han-Ming Wu, National Chengchi University, Biometrics, September
2022"The volume is a valuable methodological resource, primarily
for students interested in data science, concerned with:
understanding the fundamentals of preprocessing steps required to
transform a corpus, not always large, into a structure that is a
good fit for modeling; implementation of machine learning and deep
learning algorithms for building text predictive models under given
research contexts in which they have to be integrated."
