FAQ, content
The operator support system consists of a speech recognition function using artificial intelligence (IBM Watson) and an answer support function to
search and rank supporting document contents. In addition, we also implemented the function to record and store the feedback results from the
operator, the function to compile the recorded feedback results, the function to train Watson using the feedback result, the function to manage
operator support contents to be incorporated into Watson. We implemented a set of functions that is necessary for practical use.
