Semi-Autonomous Labeling of Unstructured Maintenance Log Data for Diagnostic Root Cause Analysis
Michael E. Sharp, Thurston B. Sexton, Michael P. Brundage
To facilitate root cause analysis in the manufacturing in- dustry, maintenance technicians often ll out \maintenance tickets" to track issues and corresponding corrective actions. A database of these maintenance-logs can thus provide problem descriptions, causes, and treatments for the facility at large. However, when similar issues occur, di erent technicians rarely describe the problem in an identical man- ner. This leads to description inconsistencies within the database, which makes it dicult to categorize issues or learn from similar cause-e ect relationships. One way to solve this problem is via natural language processing (NLP) techniques to properly tag similar ticket descriptions, allowing for more formalized statistical learning of patterns in the main- tenance data as a special type of short-text data. This paper showcases a proof-of-concept pipeline for merging multiple machine learning (ML) and NLP techniques to cluster and tag maintenance data, as part of a broader research thrust to extract structured data from largely un- structured natural-language diagnostic databases. The accuracy of the proposed method is tested on real data from a small manufacturer.
