  • In general, do the results look valid? Do any of these algorithms yield results that might be considered confusing or less than perfect?

  • Note that results can be downloaded.  What might be advantages of this portability?

On your own - network analysis and image analysis

Immersion

Immersion is a tool for discovering the connections in a corpus of email.  It analyzes the flow data (information found in email headers) and represents these as a network of entities.  The analysis is done in real time on the flow data for which you provide credentials.  The display is rich and  interactive. 
By design, Immersion collects only header information (From, To, Cc and Timestamp).  However, using the actual flow data from your account may cause concerns regarding privacy - Be sure to read over the FAQs to understand what information you are granting access to, and how it will be used.  If you do not like the terms of the tool, you can experience it with their demo data. 

Image analysis

Ukiyo-e.org is a database and image similarity analysis engine, created by John Resig to aide aid researchers in the study of Japanese woodblock prints.  The data is over 213,000 digital copies of prints from 24 institutions, and their cataloging metadata.  Metadata is indexed and searchable, as you might expect. (Details are noted in the about page.)  But images are also searchable.  Resig'sImage search uses the TinEye matching engine to determine edges in an uploaded sample and compares with analyzed edges in database, returning probable matches (edge analysis).  Use samples below to experiment.
