This posting makes the Great Books data set freely available.

As described previously, I want to answer the question, “How ‘great’ are the Great Books?” In this case I am essentially equating “greatness” with statistical relevance. Specifically, I am using the Great Books of the Western World’s list of “great ideas” as search terms and using them to query the Great Books to compute a numeric value for each idea based on term frequency inverse document frequency (TFIDF). I then sum each of the great idea values for a given book to come up with a total score — the “Great Ideas Coefficient”. The book with the largest Coefficient is then considered the “greatest” book. Along the way and just for fun, I have also kept track of the length of each book (in words) as well as two scores denoting each book’s reading level, and one score denoting each book’s readability.

The result is a canonical XML file named great-books.xml. This file, primarily intended for computer-to-computer transfer contains all the data outlined above. Since most data analysis applications (like databases, spreadsheets, or statistical packages) do not deal directly with XML, the data was transformed into a comma-separated value (CSV) file — great-books.csv. But even this file, a matrix of 220 rows and 104 columns, can be a bit unwieldily for the uninitiated. Consequently, the CSV file has been combined with a Javascript library (called DataTables) and embedded into an HTML for file general purpose use — great-books.htm.

The HTML file enables you to sort the matrix by column values. Shift click on columns to do sub-sorts. Limit the set by entering queries into the search box. For example:

- sort by the last column (coefficient) and notice how Kant has written the “greatest” book
- sort by the column labeled “love” and notice that Shakespeare has written seven (7) of the top ten (10) “greatest books” about love
- sort by the column labeled “war” and notice that something authored by the United States is ranked #2 but also has very poor readability scores
- sort by things like “angel” or “god”, then ask yourself, “Am I surprised at what I find?”

Even more interesting questions may be asked of the data set. For example, is their a correlation between greatness and readability? If a work has a high love score, then it is likely it will have a high (or low) score from one or more of the other columns? What is the greatness of the “typical” Great Book? Is this best represented as the average of the Great Ideas Coefficient or would it be better stated as the value of the mean of all the Great Ideas? In the case of the later, which books are greater than most, which books are typical, an which books are below typical? This sort of analysis, as well as the “kewl” Web-based implementation, is left up the the gentle reader.

Now ask yourself, “Can all of these sorts of techniques be applied to the principles and practices of librarianship, and if so, then how?”
