Text mining technology, used for this social media service, was originally developed by a research group from the University of Illinois. This service provides us the technology that has been put into practical use of our marketing researches.
While other services pick up only the keywords, this service is able to analyze the whole sentence and search related comments as well. Therefore, it can detect the sentence even though it doesn't include the keyword that has been set up. Also, it can analize the meaning of the words within the context and sort them into three different levels: positive, negative, and neutral.
After collecting the related comments, they will be encoded using NLP (Natural Language processing) and statistical analysis method.
