4. Verified word prediction system
-Stop predicting words that are only spoken!
In order to predict a word that comes out with big data, you need to have an advanced prediction system. Wordcast has produced a word prediction system that can analyze words of big data and produce wordbooks in real time. In addition, we received verification through the TTA on the system's analysis speed, hit rate, and elimination of unnecessary words. Through this system, there are a total of six vocabularies provided by Wordcast, and various vocabularies for each exam will be provided in the future, such as firefighters.
List of currently provided vocabulary words: SAT English, 9th grade officials (national, local, and Seoul), 7th grade officials (national, local, and Seoul), police officers, court officials, and parliamentary officials
