... asso- ciated with his educational background. To our knowledge, Read-X is the first web-based system that performs real-time searches and returns results classified thematically and by reading level within seconds. ... Search results and analyses are returned within a few seconds to a maximum of a minute or two depending on the speed of the con- nection. Read-X is enhanced with an added com...
