ABSTRACT: In the last seven years we have carried out experimental research aimed at developing software that automatically codes open-ended survey responses. These projects have led to the generation of an industrial-strength software package now in operation at the Customer Insight division of a large international banking group, and now integrated into a widely-used software platform for the management of open-ended survey data. This software, which can code data at a rate of tens of thousands of open-ended responses per hour, and that can address responses formulated in any of five major European languages, is the result of contributions from different fields of computer science, including Information Retrieval, Machine Learning, Computational Linguistics, and Opinion Mining. Our approach is based on a learning metaphor, whereby automated verbatim coders are automatically generated by a general-purpose process that learns, from a user-provided sample of manually coded verbatims, th (literal)
