Interactive Data-aware Heuristic Miner - query/filter problems

carvalhomb

Hello, all,

when trying to use the Interactive Data-aware Heuristic Miner plugin interface, I'm running into a strange behavior.

I'm trying to run queries against a log that has many trace-level attributes. I only get zero results when querying for any attribute that is not literal typed. However, I'm sure that the queries should yield results, as they run fine when I try the very same queries using Felix Mannhardt's Log Enhancement's log visualizer. Also, when the trace-level attributes are moved to event-level, the queries also yield the expected results.

Has anyone noticed this? Is it a bug? Or should I be writing the queries differently when querying for trace-level attributes?

Thanks in advance!
Regards,
Maira

HI Maira, the underlying query engine should be the same, but it is wired up differently. Could you give an example query and log that shows the issue?

Hi Felix, thanks for the reply!

I cannot share my dataset, unfortunately, but I'll try to explain better what I mean and give some examples.

I have an event log imported from a CSV. Case-level attributes in my dataset are columns that start with "CASE_". I converted the log from CSV to XES, and then used your plugin to move attributes from event to trace level. I confirmed in the event log visualization that the attributes are showing at the case level, not at event level.

The query I am trying to perform that works well in this setup looks like this (CASE_CLUSTER is a literal typed attribute):
CASE_CLUSTER="Cluster_01"
I press enter and I see the text under the search field: "using 70/1391 traces, 467/15769 events"
Then, if I try:
CASE_LENGTH>1
(CASE_LENGTH is a continuous typed attribute)
I get "using 0/1391 traces, 0/15769 events", even though I'm 100% sure I have entries that have CASE_LENGTH larger than 1. In fact, the exact same query in the Log Visualizer plugin gives me 746 traces. 

Another example:
CASE_TYPE=1
(CASE_TYPE is discrete typed)
also gives zero results in IDHM, but 129 traces in the Log Visualizer plugin.

All the above queries give me the expected results if I don't move attributes from event to trace level.

Does that make sense?

Best regards,
Maira
