We conducted text mining on data from review sites where information and reputations about companies can be shared, and evaluated the labor environment score from that data through sentiment analysis.

Furthermore, by conducting morphological analysis of the review data and analyzing co-occurring keywords, we were able to identify common words between companies and visually confirm them.
