Process mining as visualization technique

user — Fri, 27 Jan 2012 15:22:05 +0000

Process mining can produce a flowchart which is better to look at rather then 3millions rows of event data.

Animation adds to the flowchart yet another element: one can see the frequent paths taken or time delays between steps.

Preferred Concept Ancestor/Parent

In a recent process mining effort, I saw and interesting problem.

In order to simplify a log, it is important to transform events (e.g., Ultrasound of Abdomen) to a less granular events in order to make the process instances more similar to each other. But how to choose the correct ancestor concept for that – should it be Ultrasound study or Radiology Report (any one of them) or should be imaging of abdomen.

The two approaches I ended up with is a choosing a preferred hierarchy level for a given domain (e.g., anti-infectives level for drugs) or go by parent with a certain among of descendant concepts. (e.g., concepts with 500 descendant concepts are too broad parents) Solving it for any concept is not so trivial.

Does your IDR support well terminology abstractions of this kind?

Nitro – software for log transformation

ProM family of programs has a new tool.

Nitro

It can transfor CSV file into the new XES log format. Old standard was MXML. However, the new version of ProM (version 6), still supports and internally uses MXML.

More complex process representation which better models real life

Not just processes but Proclets!

You can have two patient process instances affect each other.

Process mining book

Many IT systems end up producing logs of events. These logs can be analyzed.

There is a new book by a very well know workflow researcher: Wil M.P. van der Aalst.

Highlights (taken from Springer site)

First book on process mining, bridging the gap between business process modeling and business intelligence.
Written by one of the most influential and most-cited computer scientists and the best-known BPM researcher.
Self-contained and comprehensive overview for a broad audience in academia and industry.
The reader can put process mining into practice immediately due to the applicability of the techniques and the availability of the open-source process mining software ProM.

Workflow handbook series – the 2011 book

user — Fri, 08 Jul 2011 12:48:10 +0000

Workflow Management Coalition published every year one book in a workflow handbook series. It often contains interesting case studies and hints about the future. In 2011, the book does not contain any interesting insights relevant directly to healthcare since the 2011 book focuses on social networks and workflow.

To provide more detail on the ability to work with RetroGuide or FlowGuide related data in tools like Weka or R, we provide some screenshots here.

HF extract tool (former (less suitable) name RetroGuide Admin)

MXML is format for ProM process mining tool. (workflow log schema)
Data buton creates CSV file.

There is also option to extract into ARFF.
