A first glimpse of the event log

Getting an idea about the event log scope

How many cases are described?
How many distinct activities are performed?
How many events are recorded?
What is the time period in which the data is recorded?

library(bupaR)

This information can be viewed by printing the summary of an event log

summary(learning)

or using count functions.

n_cases(learning)

Activities

Activities describe the flow of the process

Which actions are performed?
In what order are they performed?

Exploring sequences of activities

Each case is described by a sequence of activities, its trace.

Exploring sequences of activities

A frequency table of traces can be retrieved with the traces function

traces(learning)

They can be visualized using the trace_explorer function

trace_explorer(learning)

Let's practice!
