“… Automate labeling of tickets, either for training or for easier ticket resolution by a support agent [34] Chatbots [15,33,44] Spam detection [3] Performance optimization [24] Automated analysis of pictures attached to a support ticket [11] Business/process/text mining for better support system architecture [25,45] AI explainability in support ticket automating [22] Ticket resolution time prediction [10] Automated STSs in context of Internet of Things (IoT) [28] Using answering bot (Microsoft LUIS) for automated request responses [29] The findings and results in these topics were as diverse as the topics itself. Nevertheless, we were able to carve out some general findings: As in nearly any research in the field of Machine Learning the accessibility and quality of training data importantly influences the outcome of the project [1,3,25] The metrics precision and recall are by far the most-used metrics for evaluating ML ticket classification tools [5,6,18,36].…”
