When used on their own, Voyant, Carto, and Palladio, three digital humanities tools, have much to offer humanities scholars. There are some similarities between them, but each has a specialty.
Voyant’s many tools allow users to see what is included in the texts, to view trends, and to analyze the details of what happened in the interviews. It is the only one of the tools which allows users to read the actual documents.
Carto, a mapping tool, has many ways to present information using geography. It is superior to Palladio as far as answering the where things happened question, and its very useful interactive tools help to answer the when question. It does answer the who was involved question, but not to the extent that Palladio does.
Palladio, a visualization tool, is like Carto in the way that it helps readers to grasp trends in geographical locations. In the WPA Alabama interviews, Palladio can tie locations of interviews or place enslaved with each other and with topics such as the interviewer. However, it is not a mapping tool. Like Voyant, Palladio can present viewers with information regarding topics and their frequencies.
Voyant, Carto, and Palladio work well together because they complement each other. With the Alabama WPA texts, for example, one can read the actual texts in Voyant, learn more about connections between these interviewers and interviewees in Palladio, and trace when the interviews happened through Carto. Thanks to these tools, digital humanities scholars are able to gain many new insights into topics such as the WPA Slave Narratives.
