Ngrams of Social Science Disciplines

January 24, 2011

An “ngram” is an n-word phrase.  So, “human science” is a 2-gram.  If you’ve been living under a rock, you may not have heard about the latest gift from google – having scanned most published books in a number of major languages, they recently provided us the data, and a tool for easy visualization, of the relative popularity of words and phrases over time.  I thought I’d explore some terms of broad interest to sociologists with no particular idea about what I’d find.  Please take a look and help me interpret them.

Below you’ll find the relative frequency with which the major social scientific disciplines (plus psychology) are mentioned in books.  Let me explain the numbers on the Y-axis.  “psychology” is the most common word.  In 1950, it accounted for about 0.0034% of all words published.  In other words, google takes all the books published in a given year, and counts how many occurrences there are for each word.  Then it divides that number by the total number of words published.  There are many methodological considerations… for example, each book only counts once, regardless of how many copies are sold.

So what do we see?  Well, the rank order doesn’t really change over time.  Psychology gets the most mentions, then economics, sociology, anthropology and finally political science.  It’s tempting to interpret this as measuring the prominence of each discipline, but this isn’t a great test.  For starters, authors aren’t generally referring to the academic discipline when they use the word “psychology,” but they are when they use the phrase “political science.”  Sociology is probably between the two in terms of, “the share of word-mentions which actually refer to the academic discipline.”

I feel a bit more comfortable making inferences based on how each of these terms changes over time.  For example.  In in 1950, sociology received almost twice as many mentions as anthropology.  The situation was similar in 1980.  But in 1999, anthropology achieved parity with sociology, and they have been close to even in the decade since.  This appears to be evidence that anthropology gained prominence, relative to sociology, in the last half of the twentieth century.  Naturally, I don’t think we should put too much stock in this single measure of prominence.  We might want to look at trends in the number of students, and people working in each discipline.  We could count mentions in periodicals, citations to academic articles.  We could look to see how each word is used, and how much their usage changes over time.  Do these other measures corroborate, counter, or otherwise contextualize these trends?

I can’t give you easy access to all that data, but you can explore ngrams for yourself!

So readers, what do you see in this graph?  Care to nominate and discuss plausible/potentially useful and/or plainly dangerous assumptions that help us interpret these ngrams or lead us astray?

Sociology Rankings

January 7, 2011

I’m guessing most of you reading this have likely already stumbled onto this elsewhere, but just in case – Kieran Healy and Steve Vaisey thought they could put some of the infrastructure Matt Salganik has developed for his projects to use generating a new set of sociology rankings. Enjoy.

1) There is an incredible debate going on at OrgTheory in response to Fabio mostly eliminating postmodernism from his one semester Social Theory course.  Fabio with support from Gabriel Rossman, debates Thomas, Craig and Andrew Perrin. 76 Comments so far!

2) The American Anthropological Association dropped the word “science” from it’s mission statement.  The most interesting discussion of the issue is found in the comments at Savage Minds:  Why anthropology is ‘true’ even if it is not ‘science’.

3) Andrew Gelman on Tukey and the proper relationship between statistical model and statistical method.

4) The Economist discourages you from getting a doctorate.

5) Andrew Abbott interviewed on teaching and being a student.
