In my amateur-quest, to retrieve some archive that might have a semblance of approaching moderately large data for a poetry analysis project, I imagined OpenLibrary.org might offer an opportunity to download some poetry that is in the open domain. My first encounter was not encouraging. Thousands of the books listed there under poetry are distributed by the library of congress under what is know as a DAISY lock which requires a key to open and is only accessible to the blind. Imagine a library where a significant portion of the books are locked shut. Aaron Schwartz would not be amused.
Word counting is the ‘Hello World’ of big data. And my data is relatively tiny.
Below are 25 images in 5 increasing small time scales for 5 different variables (line length, verse length, avg word length, # of words per poem, # of verses per poem) derived from an analysis of a corpus of 10.5k poems scraped from poetryfoundation.org.

Recursive Deep Models for Semantic Compositionality Over a Sentiment Treebank by Socher et al. introduces Recursive Neural Tensor Network (RNTN), a model for extracting sentiment from longer phrases that outperforms previous models. The model is trained on a corpus of 215,154 phrases that were labelled using Amazon Turk. Using RNTN, single sentence accuracy increases from 80% up to 85.4%; and negation is accurately captured (a task no previous model succeeded at).
I’ve been spending some hours this weekend reviewing math at the amazing Khan Academy. The following reflection is meant as a contemplation of a trend and not in any way a critique of their valuable work.
Consider the screenshot below: where the value assigned to IAK of 66º does not accurately reflect it’s value. Both angles IAK and GCJ, if measured with a tool like a compass, are 45º angles. Yet IAK is labelled 66º and the correct answer to the angle GCJ is 24º. It does not seem like an important mislabelling, yet there is a fundamental conceptual issue at stake here. And it has a relation to poetry (perhaps tenuous) but it’s an issue of trust. As Tom Waits said: “The large print giveth, the small print taketh away”. Exactly as here: where the faint inscription at the bottom states: “Note: Angles not necessarily drawn to scale.”
