Object-Centric Process Mining (OCPM) is like a magnifying glass for analyzing how businesses and organizations operate. Imagine a very busy restaurant where each waiter, chef, and customer has specific interactions. OCPM helps us understand these interactions in detail, just like watching a scene in a movie in slow motion. It gives insights into how things work by looking at events from various perspectives. For example, we can see how a customer interacts with a waiter and how that interaction affects the chef's preparation time.
The core idea behind OCPM is to record events involving multiple objects or participants. Instead of just keeping track of one person at a time, OCPM takes into account everything happening at once. This way, it captures a fuller picture of what's going on, similar to capturing an entire soccer match rather than just following the ball.
The Importance of Leveling Up Analysis
When analyzing data, it’s essential to adjust how detailed or broad our view is. Think of it as using a camera with zoom capabilities. Sometimes we want to zoom in to see every tiny detail, like the toppings on a pizza. Other times, we want to zoom out to see the whole pizza being made. This balancing act between different levels of detail is called Granularity.
Higher granularity allows us to spot specific issues or patterns, while lower granularity helps in understanding the overall workflow. For instance, looking closely at individual test results in a hospital might reveal how long patients wait for tests, while a broader view shows patient flow throughout the hospital.
However, OCPM has faced obstacles with changing granularity. Some methods didn’t allow users to easily switch between detailed and broad views. This is where new operations come into play, enabling smoother transitions between levels of detail.
The Magic of Four Operations
To tackle the problem of adjusting granularity in OCPM, there are four operations: drill-down, roll-up, unfold, and fold. Each operation serves a unique purpose, much like different tools in a toolbox.
Drill-Down: The Micro Lens
Drill-down is like using a microscope. It lets analysts dive deeper into specifics by breaking down general categories into finer details. Imagine if, while exploring a menu, you want to see the specific ingredients in a dish rather than just the category of "pasta."
By drilling down, an analyst can separate different types of tests in a hospital setting, such as blood tests and ECGs. This ultimately helps in understanding patterns that would otherwise be missed if only looking at the general category of "tests."
Roll-Up: The Wide Angle
On the flip side, roll-up operates like a wide-angle lens. It takes detailed components and groups them into broader categories. If we think about the pizza again, this operation is akin to asking, “What type of pizza do we have?” instead of detailing every topping.
In healthcare, rolling up could mean summarizing patient interactions as “all tests” instead of focusing on each one. This is helpful when trying to get a general overview of processes without needing all the nitty-gritty details.
Unfold: Opening the Box
Next comes unfold, which adds another layer of understanding. When we unfold, we take an event and break it down by object type. For instance, instead of simply seeing a “test ordered,” we can see which test was ordered and by whom. It’s like taking that pizza box and laying everything out so you can see the different slices, toppings, and crust styles.
This operation helps analysts realize which tests are being ordered in sequence and how those actions relate to each other. It clarifies the connections between different activities, which is especially useful in complex scenarios.
Fold: Wrapping it Up
The last operation, fold, is the opposite of unfold. It groups various details back together, essentially summarizing the findings. If we think about the pizza analogy again, it’s like putting all the slices back in the box and presenting it as a whole pizza once more.
This is vital when analysts find that they need a more straightforward view after examining too many specifics. The fold operation helps maintain a clear perspective after diving deep into complexities.
Putting the Operations to the Test
To prove the effectiveness of these new operations, a case study was conducted using real-world data from a university. The dataset spanned four years and included information about student groups navigating through their courses. By applying the new methods, the researchers were able to analyze the learning processes with greater precision.
Gathering Data: A Classy Affair
Imagine gathering data from students as they progress through a course filled with numerous assignments. The researchers made sure to keep everything anonymous, like a magician concealing their tricks from the audience. Names were removed, and any sensitive info was flipped into a top-secret file.
This clever approach of using OCEL (Object-Centric Event Logs) captured the changing relationships among students, especially since groups were sometimes as dynamic as a game of musical chairs. The analysis aimed to uncover if these new operations improved the quality of process models created during the study.
Precision and Fitness: The Performance Check
After applying the new operations to the data, the results were promising. The metrics of fitness and precision were calculated to assess how accurately the discovered models reflected the actual processes.
Fitness refers to how well the model aligns with real-world behavior, while precision measures how closely the model excludes irrelevant activities. Think of it like having a basketball team that plays exactly like a coach’s game plan (fitness) but also doesn’t let any players drift off to play soccer instead (precision).
The Results: A Balanced Scorecard
The results were impressive! Most of the groups showed improved fitness and precision scores after the operations were used. It was as if the students had suddenly figured out exactly how to make perfect pizza after reviewing their recipes more closely.
However, not all groups fared well. A few experienced low scores. The researchers traced these issues back to the way students participated in the course—some switched groups frequently, causing confusion in the data representation. It was like trying to follow a fast-paced sports game where players kept changing teams mid-play!
Creative Trouble: Outliers and Errors
To understand why some groups exhibited low scores, the researchers looked at outliers, which are values that stand out from the rest. The two groups that struggled were those with a high turnover rate. Students frequently changed groups like it was a game of tag. This resulted in models that didn’t accurately reflect their actual experiences.
In these cases, traditional OCPM techniques were not able to keep up with the dynamic nature of the groups, leading to errors in model discovery.
Lessons Learned: A Touch of Comedy
This entire exploration revealed a valuable lesson—while complex processes can be tricky to capture, multi-dimensional analysis (using our new operations) is much like using a GPS that can help avoid traffic jams. To simplify things: if you make the pizza easier to read (with clear labels and toppings), it’s less likely that someone will complain they didn’t order mushrooms!
Conclusion: A Slice of Insight
In summary, Object-Centric Process Mining and its new operations—drill-down, roll-up, unfold, and fold—have proven essential tools for analyzing business processes. They allow users to capture complexity in a manageable way, offering both detailed insights and a broad overview when needed.
The practical application in an educational setting showcased the effectiveness of these operations, helping analysts gain deeper insights into student interactions and progress. It’s like going from a black-and-white photo of an event to a vibrant, full-color image where every detail comes to life.
Future Directions: What Lies Ahead?
As we look ahead, there’s much to explore! Future research can focus on making it easier to calculate fitness and precision, and improving techniques for tracking dynamic relationships.
The evolution of OCPM will pave the way for better insights, allowing organizations to streamline their processes effectively. By integrating the new operations into existing tools, analysts will be better equipped to handle the complexities of modern workflows, ultimately leading to improved efficiency and greater success.
And who knows? Maybe one day, we’ll be able to roll-up a slice of data analysis while enjoying a slice of pizza—talk about a win-win situation!

Title: Advancing Object-Centric Process Mining with Multi-Dimensional Data Operations
Abstract: Analyzing process data at varying levels of granularity is important to derive actionable insights and support informed decision-making. Object-Centric Event Data (OCED) enhances process mining by capturing interactions among multiple objects within events, leading to the discovery of more detailed and realistic yet complex process models. The lack of methods to adjust the granularity of the analysis limits users to leverage the full potential of Object-Centric Process Mining (OCPM). To address this gap, we propose four operations: drill-down, roll-up, unfold, and fold, which enable changing the granularity of analysis when working with Object-Centric Event Logs (OCEL). These operations allow analysts to seamlessly transition between detailed and aggregated process models, facilitating the discovery of insights that require varying levels of abstraction. We formally define these operations and implement them in an open-source Python library. To validate their utility, we applied the approach to real-world OCEL data extracted from a learning management system that covered a four-year period and approximately 400 students. Our evaluation demonstrates significant improvements in precision and fitness metrics for models discovered before and after applying these operations. This approach can empower analysts to perform more flexible and comprehensive process exploration, unlocking actionable insights through adaptable granularity adjustments.
