"Classifying Opinion and Editorials can be time-consuming and difficult work for any data science team, but Cloud Natural Language was able to instantly identify clear topics with a high-level of confidence. This tool has saved me weeks, if not, months of work to achieve a level accuracy that may not have been possible with our in-house resources."
