The original WWW interface for LSI was devised by Susan Dumais and Loren Shih at Bellcore. The prototype interface was designed to work with the original Bellcore implementation of LSI, making it obsolete when LSI++ was completed. The interface has been completely reworked to add new features, to make it easier to use, and to hide the details of LSI from the user as much as possible. The new LSI WWW interface uses the LSI++ Application Programming Interface to set the parameters for a query, process the query, and formulate the results.
