Visualizing Topics in ELH
Sun Nov 25, 2012
ELH I thought would be an interesting journal to try, as it publishes articles in each issue on quite a range of literary periods, often ranging from medieval to twentieth-century material. I assumed that LDA would be likely to identify each of these periods as a topic. To test this, I downloaded the entire set of articles from JSTOR and created a fifty-topic model. From there, I wanted to chart the proportion of each topic in each document. I was able to import the data in R and use ggplot2 to create the following graph:
As you can see, many of these topics are identifiable from even two-word samples. Others show a need of lemmatizing (a slow process using the python NLTK, though effective), or of further splitting. Perhaps fifty topics is not quite enough.
The code has to transform row data to column-form in order to be efficiently sorted. It then used the ggplot2 facet_wrap feature to create the graph. I’d be happy to share it, if anyone’s interested, though it uses a for-loop, which I understand to be bad R. You also have to pre-process the JSTOR files to associate dates with the files themselves. I have a perl script for this.
For reference, here is the complete list of topics generated by MALLET:
