P2 1-1:

4 V’s of Big Data

• VOLUME 量大
• VELOCITY 数据增长速度
• VARIETY 种类多
• VERACITY 真实性

Is on the interplay between event data and processes, and process models.

Process mining use cases

P3 1-2:

Three types of mining :

• Process discovery 流程发现
• Performance checking 一致性检查
• Enhancement 增强

It is not just about collecting data , it's about analyzing processes.
That is one of the key things.

Event Log Table ：

Every line, corresponds to an event .

Three types of relationships between models and event data:

• Play-Out

• Play-In

• Replay

Play-out is about the classical use of process models not involing any event data.

Play-in corresponds to discovery.

Play Out:

Single execution for single trace:

Many execution for many traces:

P4 1-3:

Process Discovery

For example:

We can see a sentence and compare that to atrace in an event log, and we can think of the language as a process model.

P5 1-4:
