A more detailed comparison

Visualizations might be a good option for you if...

  • You have limited or no coding experience
  • You want to do a preliminary exploration of your data
  • You are interested in exploring geographic analysis, sentiment analysis, and topic modeling
  • You want to do a classroom demo of some text analysis methods

Limitations:

  • Not all sources are available in Visualizations
  • Full text cannot be downloaded off the platform; however you can export the data used to produce the visualization
  • Limited ability to customize the visualizations
  • Maximum of 10,000 documents per visualization
  • Maximum of 10 visualization projects

Workbench might be a good option for you if...

  • You have more advanced coding experience (in R or Python)
  • You want to use your own text analysis methodologies 
  • You want to export the data to perform your own analysis
  • You want to upload your own data to the virtual environment to do analysis

Limitations:

  • Rolling 7 day export limit of 30MB per week per Workbench
  • 1 million metadata records per week per workbench
  • Due to copyright/source text licensing, you are unable to download a complete, un-altered copy of all full-text holdings. You are able to download aggregated and analyzed data that cannot be reassembled into full-texts, such as word counts, topic models, rearranged texts, etc. Please reach out to us if you have any questions or concerns about this policy.
