Tradd.us is a free online translation service that combines the power of Google Translation Service and Open Calais to improve text translation and comprehension.

Open Calais is used to identify tags related to the text being translated, helping users to have a better understanding about what was translated and the context of the text.

Besides that Tradd.us can discover word synonyms, helping you understand, comprehend and assimilate new words.

We also show the best ranked sites and related terms based on the word or expression selected, in a quick and easy way!

SemanticProxy, created by the Calais team, makes it easy to generate rich semantic metadata for individual Web pages. Simply paste the page's URL into the tool.  Programmatic use of SemanticProxy requires a Calais API key (your current Calais key will work).

Run your own demo to see how easy tagging can be.

Submitting Content to Calais

If you’d like to start building simple workstreams that integrate Calais processing the command line Calais submission tool is a good starting point. The tool accepts input from STDIN, writes output to STDOUT and reads your processing parameters from a configuration file. You can download the application, source code and documentation here. Use of Calais Command Line requires a developer key and a current version (V 6) of the Java runtime environment on your machine.
