Abstract

IoT devices supporting business processes (BPs) in sectors like manufacturing, logistics or healthcare collect data on the execution of the processes. In the last years, there has been a growing awareness of the opportunity to use the data these devices generate for process mining (PM) by deriving an event log from a sensor log via event abstraction techniques. However, IoT data are often affected by data quality issues (e.g., noise, outliers) which, if not addressed at the preprocessing stage, will be amplified by event abstraction and result in quality issues in the event log (e.g., incorrect events), greatly hampering PM results. In this paper, we review the literature on PM with IoT data to find the most frequent data quality issues mentioned in the literature. Based on this, we then derive six patterns of poor sensor data quality that cause event log quality issues and propose solutions to avoid or solve them.

  • Time shifts commonly arise from incorrect calibration of individual sensors.

    “Such situations commonly arise, for instance, from incorrect calibration of individual sensors, for example, [36].”

    From Case-Based Data Quality Management for IoT Logs: A Case Study Focusing on Detection of Data Quality Issues (2025) · cites this paper as [36]

    Pattern 6 describes activity start or end times being logged incorrectly because sensor detection does not coincide with the activity. It suggests changing sensor placement or range, but does not attribute these time shifts to incorrect calibration of individual sensors or say that calibration errors commonly cause them.

  • Bertrand et al. reviewed the IoT-BPM literature and found that the most often reported DQIs, i.e., noise, outliers, and missing data, correspond to the most often reported issues in IoT in general by Teh et al.

    “Bertrand et al. [36] reviewed the IoT-BPM literature to describe the IoT DQIs and the event log DQIs encountered by previous research. The results indicate that the most often reported DQIs, i.e., noise, outliers, and missing data, correspond to the most often reported issues in IoT in general by Teh et al. [6].”
  • Although IoT data quality is acknowledged as a problem in IoT-enhanced BPM, there is little literature proposing methods to address data quality in this context.

    “Although IoT data quality is acknowledged as a problem in IoT-enhanced BPM [11,31,36], there is little literature proposing methods to address data quality in this context.”
  • Neglecting these errors results in flawed data, which can lead to unreliable analyses and ultimately erroneous decisions.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
