Hybrid datafication of maintenance logs from AI-assisted human tags

Abstract

One of the main challenges of applying AI to certain datasets derives from the datasets themselves being unstructured, unclear, and ambiguous. Furthermore, the insights that are to be gained reflect the quality of the data itself; if the data is skewed, so will be the insights. This problem is not unique to AI technology. People looking back at logs of past events often struggle to understand what was recorded, and to put together a timeline amongst a range of actors. AI technology can help humans sort the data out, but it does not provide the same insight often found in the background knowledge of human participants. This contextual weakness has made unstructured data hard to process. In our work, we have studied typical manufacturing maintenance logs to explore whether and how we can apply AI technologies to gain more insight from this - often vast and under-used - data-source. Our approach combines AI techniques for NLP, machine learning, and statistical processing with human contextual knowledge to quickly develop structured semantics reflecting unique datasets.
