TL;DR
This paper introduces iPACK, an incident-aware method for aggregating duplicate support tickets in cloud systems by integrating customer tickets and cloud incident data, significantly improving accuracy over existing approaches.
Contribution
The paper presents iPACK, a novel incident-aware approach that fuses customer and cloud incident information to effectively identify duplicate tickets in complex cloud environments.
Findings
iPACK achieves an F1 score of 0.871 to 0.935.
It outperforms state-of-the-art methods by 12.4% to 31.2%.
Extensive evaluation on real-world Azure data validates its effectiveness.
Abstract
In cloud systems, incidents are potential threats to customer satisfaction and business revenue. When customers are affected by incidents, they often request customer support service (CSS) from the cloud provider by submitting a support ticket. Many tickets could be duplicate as they are reported in a distributed and uncoordinated manner. Thus, aggregating such duplicate tickets is essential for efficient ticket management. Previous studies mainly rely on tickets' textual similarity to detect duplication; however, duplicate tickets in a cloud system could carry semantically different descriptions due to the complex service dependency of the cloud system. To tackle this problem, we propose iPACK, an incident-aware method for aggregating duplicate tickets by fusing the failure information between the customer side (i.e., tickets) and the cloud side (i.e., incidents). We extensively…
