Dear @philipempl
Unfortunately the problem of resource-based conformance checking is significantly different from control-flow based conformance checking.
Based on some ideas for a lab project in an university, I can recommend you to:

Hello @fit-alessandro-berti,
thank you very much for your input on resource-based conformance testing. Your ideas are very interesting, and I appreciate your suggestions on approaching this problem. I will definitely consider using declarative models, anomaly detection, and using SNA metrics and extended metrics as you suggested.
Of course, I will also cite the research paper behind this great Github repository. Kudos for this work.

Hello @philipempl
I was one of the authors of the orgmining 2.0 paper and saw this thread by chance when checking the recent pm4py updates.
Our work on orgmining 2.0 has a published version (doi), in which we propose a new form of organizational models that allow evaluation of org. models vs. logs, paving the road to conformance checking. In that work we have not considered ordering of events due to our focus on organizational grouping.
There is some other relevant work built on control-flow models that are resource aware, which might be useful: De Leoni et al., Mannhardt et al.
Cheers
Dear @roy-jingyang
We also implemented your approach (OrgMining 2.0) in pm4py. See: https://pm4py.fit.fraunhofer.de/documentation#item-11-8
Cheers, Alessandro
Description:
I am currently working on a research paper where I need to identify malicious activities by detecting cases where a resource executes an unauthorized activity. To achieve this, I want to perform conformance checking using the pm4py library. However, when I use the alignments.apply_log() function, the conformance score is always 1, even when the activity is not covered by the model. Therefore, I would like to know if there is a way to incorporate the resource parameter in the conformance checking, so that I can detect when the right resource executes the right activity.
Steps to Reproduce:
Expected Result:
I expect the conformance checking to take into account the resource parameter and identify cases where the right resource does not execute the right activity.
Actual Result:
The conformance score is always 1, even when the activity-resource tuple is not covered by the model.
Additional Information:
I have searched through the pm4py documentation and repository, but could not find any answer, function, or parameter to my question.
