How to approach DH?

-Text analysis
-Social network analysis
-Geo-spatial mapping
-Distance reading / content analysis
-Visual/sound analysis


Dirt Directory (
-comprehensive website/registry listing resources to help you conduct research
-can be categorized by your approach (text analysis, numeric data, etc.)

Tags (for twitter date collection)
-allows you to collect any tweet you want by the minute
-only need twitter and gmail account
-using twitter’s API including location, vast amounts of data

Voyant ( for text analysis
-load your own dataset
-enables you to quantify the humanities into datasets just as scientists and social scientists do
-shows (from left to right) a word cloud, an automatic summary (including words per sentence, frequent words, distinctive words, vocabulary density, etc.), the top five words, and words preceding and following specific words
-tool to exclude phrases you do not want to count as words

Programming Historian (
-valuable especially for isolated regions where resources may be more limited
-always looking for contributors
-tutorials are well-written
-using regular expression to clean OCR text

Open Refine (

Text grid labs – downloadable application for text analysis
-upload photos of manuscript
-can embed links, etc.

Gephi ( for visualization

Palladio ( for visualizing historical data
-perfect for exploring and catered to be user-friendly
-partially funded by NEH

Google nGram

Social network analysis
-lots of statistics
-all you need is two columns of two related persons
-difference from Palladio – shows nodes (persons beyond the first degree of separation)
-analysis includes:
-maximum geodesic distance – diameter (“hops” of degrees of separation from one side of the chart to the other side)
-centrality (how many times people have go through you to get to another relation)
-exemplifies “power law curve”
-Eigenvector unit – “proximity to power” (how close you are to people with high scores of centrality)


Omeka and
-free, easy, nice to use
-really good at presenting all the metadata, making it very accessible
-comprehensive source for manuscript, images, audio, video

-good for articles, books, embedding
-create things in zotero and you can embed on Omeka using a connecting tool
