Text Analysis with R for Students of Literature
Text Analysis with R for Students of Literature

Our ability to access, process, and analyze large quantities of data has been increasing at a dizzying pace over the last few years. This data-driven revolution is fundamentally changing many professional and academic fields. Many people, especially the long-term practitioners in humanities and similar disciplines, find this change worrying, and in many ways exactly contrary to the spirit of these disciplines. Pouring over long and demanding texts, while internalizing them and becoming personally immersed in them, seems to be at the very core of what these disciplines are all about. And yet, as both a lover of humanities and a die-hard techy, I find this latest development incredibly exciting.

The title of this short book makes it eminently clear who the intended audience is: students of literature who are interested in using R for textual analysis. R is a very powerful programming language used for statistical analysis. Textual analysis is a very prominent aspect of modern data science, so there are many well-known and established tools and techniques that can help one with this task. However, the aim of this book is neither to teach R or programming, but to give the Literature students just the most basic tools needed to do some relatively straightforward textual analysis. The book jumps straight into the examples almost from the very first page. The obvious virtue of this approach is that you can start doing some interesting work rather quickly, and as long as your own research doesn’t depart dramatically from the examples given in the book you should be able to use the books as a reference and a primer for your own work. However, if you have some slightly more demanding problems that you are trying to work on, then after finishing this book you might want to go to a specialized book on R programming that will give you enough foundation to work on a larger variety of problems.

The book takes the freely available text file of “Moby Dick” and runs a variety of textual analysis on it: simple word count and word frequencies, correlations between various “special” words, context analysis, etc. In the latter chapters it moves from a single book to a corpus of books for more interesting look at themes across many texts. I found the last chapter on topic modeling especially fascinating, but way too brief. I guess I will now have to take a look at other sources to learn more about this line of analysis.

This books is very pedagogical in its style. Oftentimes the author would present two different solutions to a particular problem - one using a very simple yet hard to understand R command, and another broken down into several self-contained chunks. I find this approach very educational and helpful.

Even though this is primarily a book intended for literature students, I would actually strongly recommend it to anyone interested in text mining, text analysis and natural language processing. It is a very gentle and approachable introduction to the whole world of textual analysis.

Introduction To Artificial Intelligence (Undergraduate Topics In Computer Science)
Introduction To Artificial Intelligence (Undergraduate Topics In Computer Science)
par Wolfgang Ertel
Edition : Broché
Prix : EUR 36,87

4.0 étoiles sur 5 Valuable and Pedagogical Introductory Text, 2 juillet 2015
Artificial Intelligence is by now a relatively old field, having originated in the early days of the digital computer revolution. However, it has had a very rocky and turbulent history, going through several cycles of overblown expectations followed by almost equally dramatic swings towards disillusionment and skepticism. In recent years, though, it has matured into a very solid and practical discipline that exercises an ever growing importance across a wide breadth of technologies and professions. We increasingly take speech recognition, handwriting recognition, and natural language search for granted. Basic familiarity with what Artificial Intelligence is, and what tools and techniques fall under its domain, are becoming ever important aspect of a variety of professions and occupations.

There is no shortage of books and resources on Artificial Intelligence. However, most of them fall squarely into two main camps: discursive overviews for the general audience, and highly advanced textbooks requiring deep familiarity with many advanced technical concepts. Ertel’s “Introduction to Artificial Intelligence,” even though it’s pretty technical in its own right, is still fairly accessible introduction to this field for anyone with solid grasp of basic college-level math and computer science concepts.

The book is organized somewhat chronologically along the lines of topics that have historically formed the main organizing principles for the study of Artificial Intelligence - first and second order logic, propositional calculus, PROLOG, machine learning, neural networks. Some of the earlier chapters’ material is a bit dated, and in some cases unfamiliar to students and practitioners in North America. For instance, it seems that PROLOG never quite got a hold on this side of Atlantic. There are a few more or less amusing examples of how quickly technology ages, such as references to Google Video links, which haven’t been around for a few years now. I would have also liked a substantially more material on machine learning and neural nets, maybe at the expense of the earlier chapters. These topics have a lot of practical applications today, and seem to be the guiding paradigms for Artificial Intelligence as a whole for a foreseeable future. Nonetheless, the book overall is very readable and relevant.

One of the most valuable aspects of this book are the worked out examples and numerous (solved) exercises. Working through problems is, by far, the best way to learn any new material, and this book provides the reader with numerous and wide-ranging opportunity to do exactly that.

Overall, this is a very well written and pedagogical book that fills an important niche in the Artificial Intelligence educational literature. Highly recommended.

5.0 étoiles sur 5 Impressive Introduction to Predictive Modeling with R, 30 juin 2015
Ce commentaire fait référence à cette édition : Applied Predictive Modeling (Relié)
“Data Science” is the most exciting research and professional fields these days. It is creating a lot of buzz, both within the academy as well as in the business world. Detractors like to point out that most of the topics and techniques used by people who call themselves Data Scientists have been around for decades if not longer. However, has often been the case that a combination of topics and methodologies becomes important and concrete enough that a truly new subfield emerges.

Predictive Modeling is a particularly exciting subfield of Data Science. Thanks to the few recent high profile news grabbing success stories (the 2012 US presidential election, the Netflix prize, etc.) it has attracted a lot of attention and prominence. Thanks to the increased use and availability of data in all walks of life we are increasingly able to make reliable predictions and estimates regarding topics and issues that affect us in very substantive ways. This ability may sometimes seem almost magical, but behind it lay some very accessible ideas and techniques. “Applied Predictive Modeling” aims to expose many of these techniques in a very readable and self-contained book.

This is a very applied and hands-on book. It guides the reader through many examples that serve to illustrate main points, and it raises possible issues and considerations that are oftentimes overlooked or not sufficiently reflected upon. For instance, the way we model as simple of a data as a calendar date can have a significant impact on the kind of analysis and predictive model we choose. This is the kind of information that is often not discussed in other modeling books and can sometimes take years of practical experience before its impact is fully appreciated.

The book has a fairly low access bar, but it is definitely not intended for a complete novice. It assumes a fairly decent background in statistics, R language, and at least a passing understanding of machine learning. Many of these techniques are covered in this book, but mainly as summaries and refreshers. Each one of them could use up a book of its own, ore even a whole collection of books.

One of the best features of this book is that the authors understand that predictive modeling is not just a bunch of statistical and computational techniques. Understanding the data, how to obtain it, manipulate it, and format it, are some of the most crucial steps for predictive modeling (and other data-driven fields), and are often overlooked and not sufficiently explained in many other books and papers that I have come across. The same can be said about the model selection - the choice of a model and its predictive power will crucially depend on the kind of phenomena that we are predicting, as well as on what exactly are we trying to predict. This book does an excellent job in guiding the reader along these paths and installing the necessary intuitions required for successful predictive modeling. Here too, like with most things in life, there is no substitute for years of experience working with actual real world problems, but going through this book will ensure that you don’t have to stumble too much with your first steps.

Highly recommended.

Face to Face with Jesus: Reflections for a Disciple
Face to Face with Jesus: Reflections for a Disciple
par Bruno Forte
Edition : Broché
Prix : EUR 8,49

5.0 étoiles sur 5 Spiritual Companion to St. Mark's Gospel, 30 juin 2015
Ce commentaire fait référence à cette édition : Face to Face with Jesus: Reflections for a Disciple (Broché)
At the center of Christian life and ministry is the Bible, and at the center of the Bible are the Gospels. These powerful narratives of birth, life, death and resurrection of Jesus were written by the first century Christians in order to inform and instruct the new and aspiring followers about the essential aspect of Jesus’ unique message and mission.

Among the four canonical Gospels, the Gospel of Mark is usually assumed to be the earliest one written, and a source and inspiration for the other two “synoptic” Gospels. It is the shortest and in many respects the rawest of all the Gospels. It uses very direct and even unrefined language and narrative structure. The Jesus that Mark presents to us can sometimes seem very rough. This is not the “nice” Jesus that has pervaded many modern sentimentalist ideas about Him, and influenced much of the “moralistic therapeutic deism” that passes for Christianity in many circles these days.

In “Face to Face with Jesus” Bruno Forte takes Mark’s Gospel as the starting point for his more intimate exploration of Jesus and what a genuine encounter with Him means for our lives. This very short book is not meant to be a commentary on Mark’s Gospel. Forte uses several passages from this Gospel in order to illustrate his points and evince insights, sometimes quoting the passages at length. The familiarity with Mark’s Gospel is of course desirable, but not necessary, for full appreciation of this book. Rereading it would probably be a good idea though. The book reads like a very well written extended homily. Forte’s style is very erudite and yet approachable - this is by no means a recondite theological thesis. “Face to Face with Jesus” makes demands on us to take Jesus’ work and ministry very seriously and open ourselves to the possibility of radical inner transformation that He asks from us.

Forte is also very clear in promoting a very strong emphasis on the radically different and supernatural nature of Jesus’ message and life. Many Christians, even the most faithful ones, fall into the trap of conceptually and rhetorically sacrificing Jesus’ divinity in order to make him more accessible and intelligible in terms of modern social and cultural categories. “Face to Face with Jesus” is, fortunately, not one of those books.

Even though this is a very short book, the reader should really take his time to go through it thoughtfully and deliberately. Anything else would not do it justice. As a spiritual nourishment I highly recommend it to everyone wanting to grow in their faith.

The Antarctic: A Very Short Introduction
The Antarctic: A Very Short Introduction

Edition : Broché
Prix : EUR 10,55

4.0 étoiles sur 5 Good Intro to Antarctic, 8 avril 2015
Ce commentaire fait référence à cette édition : The Antarctic: A Very Short Introduction (Broché)
The Antarctic is perhaps the strangest and most fascinating place on Earth. The last continent to be discovered and explored, it is still politically a unique and peculiar geographic entity. Its extremely harsh climate makes it uniquely inhospitable and unwelcoming place for humans to visit. And yet, like many such remote and mysterious places it has been drawing explorers, adventurers and visitors for as long as it has been known.

This is a very well written and pretty detailed book about the Antarctic. It explains well what is usually meant by the terms Antarctic and Antarctica, and how these entities are usually treated in international law and politics. The book spends quite a bit of space explaining the geography and climate of this remote region. However, the book’s unique strength lays in its treatment of the political nature of The Antarctic. Ever since it was discovered various nations had laid claims on the vast regions of the Antarctic. Oftentimes these claims overlap, and have resulted in contentions that have not been properly resolved to this day. Since the 1950s, though, Antarctica has enjoyed a very unique status in international law thanks to the treaty that made the whole continent into one great scientific lab.

The book covers several interesting scientific investigations that have been going on in the Antarctic for years. Unfortunately, it doesn’t mention any of the really cool Physics and Astronomy experiments that have been performed there in recent years.

Another topic that I wish the book explored was the treatment of The Antarctic in arts, literature and film. There is a mention of Edgar Allan Poe’s “The Narrative of Arthur Gordon Pym of Nantucket”, but it was only mentioned in passing as an example of early misconceptions about the Antarctic. Due to its “alien” nature the Antarctic has been a source of inspiration for quite some time, and several of my favorite movies are set over there.

The author also mentions in passing several topics and social concerns that seem to have become the focal points of all academic writing these days, but are completely at odds with a book of this nature. They feel very out of place and even grotesque when talked about in a book about the Antarctic, but fortunately they don’t take up much space and can be safely skipped.

Overall, this is a fairly interesting and well-written book. Despite the few shortcomings I noted, I still think it’s probably the best short introduction to the Antarctic, and one of the better books in this Very Short Introduction series. Recommended.

5.0 étoiles sur 5 Murakami's Modern Fairy Tale, 8 avril 2015
Ce commentaire fait référence à cette édition : The Strange Library (Broché)
As a long time Murakami fan I was really excited to see this “new” book pop up under his name on Amazon. It turns out that this is a reprint of one of his very first prominent stories, adapted to a look and feel of an illustrated comic book. In fact, the well-crafted and richly illustrated book is a wonderful publishing gem in its own right. In the age where more and more books are consumed in the electronic format, it’s a wonderful sensory experience to enjoy the book as a physical artifact again. This is one of those books that you definitely want to get in the hard copy.

After the disappointment that I’ve had with 1Q84, I decided to go back and reread some early Murakami. “The Strange Library” contains many of the themes and narrative elements from Murakami’s early works: the longing and loss, strange subterranean buildings, mysterious animals and strangers, and, of course, the Sheep Man. The story/book is part allegory part modern fairy tale. It’s a very dark and brooding tale that may leave you saddened and perplexed. It still has a lot of insight into the intimate corners of our nature. Like most other Murakami stories, it is also replete with plot twists and embellishment that don’t seem to lead anywhere, but, like a true labyrinth, are necessary for the whole to function following its own inner logic.

This may not be the best Murakami story, but it is still an immensely satisfying reading experience. Especially for his die-hard fans.

Hormones: A Very Short Introduction

Ce commentaire fait référence à cette édition : Hormones: A Very Short Introduction (Broché)
In popular culture hormones are considered chemicals that cause a lot of disruptive or unwanted behaviors: from a teenager’s acting out, to rampant promiscuity, to drug abuse in professional sports. In this view hormones are thought as something of an “add on” to your normal bodily homeostasis. However, hormones are an essential part of our biological makeup, and without them we simply couldn’t function. They are the overarching “signaling” chemicals, generally secreted in one part of the body and carried by the bloodstream to the other parts.

This is a very well written and thorough book on hormones. It gives a short historical account of their discovery and the evolution of our understanding of these important substances. The book covers the biochemistry of hormones, and the physiology of their secretion and action. Unsurprisingly, the bulk of the book deals with human hormones and the associated physiological conditions that accompany them.

The book gave me a new appreciation of the incredibly subtle and complex role that hormones play in our bodies. It also managed to dispel certain myths that I’ve had about hormones. (For instance, both testosterone and estrogen are present in both sexes. They are not THE sex hormones as conventionally understood.) I also learned how much interaction there is between different hormones, and that this is still an area that is not completely well understood, where a lot of current research is going on.

As an aside, just like with any other book written for the general audience that contains “medical” information, there is a danger that a fair number of readers of this book may be tempted to self-diagnose after reading it. Don’t. You will most likely misdiagnose yourself, and make yourself unnecessarily worried. If you suspect that you might have a medical condition that could possibly be related to hormonal imbalances, you should consult your doctor.

Overall, this is a pretty good book that taught me a lot of new things about hormones and human physiology in general. Highly recommended.

The Python Workbook: A Brief Introduction With Exercises and Solutions

5.0 étoiles sur 5 Solid Python Exercise Book, 24 février 2015
Ce commentaire fait référence à cette édition : The Python Workbook: A Brief Introduction With Exercises and Solutions (Relié)
Python is a very popular and very powerful modern programing language. In terms of its syntax and style it might be one of the “cleanest” programming languages out there. Yet, its deceptively simple code often belies the underlining power and efficiency. In terms of professional development, knowledge of Python is right now probably one of the most sought out technical skills. Learning Python is very learning for many technical professions, and this small books is a very useful resource to have for exactly such purpose.

The best way to learn any new skill is to do a lot of exercises and solve a lot of problems. This workbook provides 174 relatively straightforward excises that cover most important programming topics. The exercises are dived into eight different sections, such as “Loop Exercises,” “Dictionary Exercises,” “Recursion Exercises,” etc. The statement of the exercises/problems is very clear and well explained, and it’s usually covered in one or two paragraphs. The exercises also state if they are solved or not, and how long in terms of lines of program the solutions are.

As is to be expected from an workbook of this kind, many of the exercises come with a solution that is provided at the back of the book. The solutions are very to the point and concise, with a minimal amount of comments and explanations. Comments are given in the form of commented-out lines of code, while the short explanations are given on the side in grey boxed areas. All the code is properly and cleanly formatted. It is also color coded, which is a nice bonus and greatly helps with readability.

The content and the difficulty level of this book are both very accessible. The book is suitable for a gentle introductory college level course, or even a solid high school intro to programming course. None of the exercises require more than a few dozen lines of code to implement, and thus are not too demanding on your time and effort. A book like this one might in fact be ideal for someone aiming to learn programming or Python on his own. It can also be a very good supplementary material for an online course, which is in fact how I have been mostly using it. After a few weeks of going through these exercises I find that my Python fluency has greatly increased, and I am able to think in Pythonese and code much more efficiently. The book is a great resource for acquiring the basic coding fluency, but for more advanced programming skills you will need a more substantial reference.

Genes: A Very Short Introduction-

Ce commentaire fait référence à cette édition : Genes: A Very Short Introduction- (Broché)
For as long as humans have been occupied with agriculture and raising of cattle, concern with selecting the best crops and the best farm animals has been an important intellectual topic. However, only with the work of Gregor Mendel in the late nineteenth century have we started to get a better quantitative picture of how heritability really works. Remarkably enough, most of the deep insights that Mendel came up with have survived subsequent major revolutions in our understanding of molecular nature of inheritance.

This little book aims to cover all of the major topics in the study of genes and genetics. It has a short historical preamble which is followed by the attempt to give the best definition of what genes are. The book deals in some detail with the biochemistry of cells and cellular development. It also goes into some detail to cover the human genetics, and human pathologies that have genetic component in particular. It contains a lot of interesting information in its very short format.

To its credit the book does not shy away from some more controversial topics in human heritability and genetics, such as the existence and nature of races and group differences. The book tries to present all sides of such debates fairly and equitably. (A bit too equitably for my taste.) It leaves it up to the reader to form his own conclusions, or to seek out additional resources and information on these matters.

One of the biggest insights that I’ve gained from reading this short book is that the very notion of a “gene” is not as well defined on the most fundamental level as I had previously thought. The notion of a “gene” is best defined and most useful for single well defined characteristic of an organism that is due to a very precise single region of the DNA sequence. (Even there there are many important caveats.) For heritable characteristics that are far less well defined in terms of their determination by the DNA code the very notion of a gene becomes much more dubious. Nonetheless, our main macro insights about genes and genetics are still largely valid, but we need to keep our expectations from the molecular genetics somewhat in check.

The book is very well written, and it is organized thoughtfully and comprehensively. It still uses quite a bit of scientific jargon and more advanced concepts that many general readers may be unfamiliar with. Nonetheless, all of that should make for a more educational and informative book. I really enjoyed reading it and would strongly recommend it to anyone who has any interest in genetics, biology, or science in general.

Microbiology: A Very Short Introduction

Ce commentaire fait référence à cette édition : Microbiology: A Very Short Introduction (Broché)
Biology is a fascinating discipline and one of the oldest scientific subjects. Fascination with the living world is deeply ingrained in the human psyche - we do depend on the knowledge and understanding of other organisms for our survival. However, for most of the human history the systematic study of biology focused almost exclusively on macroscopic organism. Only with the invention of the microscope were we able to study the tiniest organism - the unicellular organism that predominate the Biosphere.

This short book covers all of the known microorganism in a more or systematic way - bacteria, archaea, unicellular eukaryotes, and it even briefly goes over the viruses. (There are a few very good Very Short Introduction books that cover some of those biological entities in their own right.) The book gives you a remarkable amount of information about microbiology for its size. It covers the evolution of microorganisms, and their biochemistry. Unsurprisingly, it gives a lot of space to microorganisms that cause various diseases, especially in humans. Historically this was the primary motivation for studying the microorganisms, and it’s still a very relevant medical issues. Unfortunately, however, it has biased us to think of all microorganisms as harmful. The vast majority of them are either neutral or beneficial. Human body in terms of the sheer number of cells is more microbial than multicellular. Our guts alone are an incredible microbiological ecosystems, and we are only now starting to understand how many of them affect our well being.

One of the issues that I have with this book is that it is pretty dense in terms of jargon and concepts that it covers. The writing style and the presentation are very fluid and well organized, but you still have a lot of very high-level scientific concepts that might be unfamiliar to most readers of this book. If you are willing to be challenged, though, this could be an ideal small book to get you acquainted with the up-to-date science and biology lingo.

The book seems very fresh and up to date with the latest insights and developments in the field of microbiology. One of the more interesting insights for me was the recent prevailing theory of the tree of life which postulates that the eukaryotes evolved from archaea. Thus, it seems to upend the three-pronged tree of life picture (bacteria, archaea and eukaryotes) that has been around for just a few decades. Another interesting thing that I’ve learned from this book is that the vast majority of microorganisms cannot be cultured in the lab, and are thus not very well studied or understood. This puts in perspective the amount of knowledge that we have about the natural world.

Unfortunately, this book will not bring you any closer to the understanding of the ultimate origins of life. This topics remains an enduring mystery, and for its resolution will likely require much more powerful analytical, experimental and computational resources than we have today.

This is a very interesting and well written little book that I would strongly recommend to anyone interested in biology or science in general.
