For the Dutch Ministerie van VWS we developed a classification solution, with which employees of the ministery can add keywords to publications of the ministery’s website. The system gives suggestions to users, which can be accepted or rejected. Also, new keywords, not generated by the system, can be added. Another advantage of semi-automatic classsification is, that the system quickly adopts new insights, gets trained, and becomes better every day. In about a year’s time we reached a classification accuracy of over 97%! The user interface was developed by the ministery itself.
