Event abstraction is a powerful tool for dealing with overly detailed process models generated from event logs. Here's how it can improve readability and manageability:

**1. Reducing Complexity:**

* Event logs often capture very granular activities.  Abstraction groups these low-level events into higher-level, more meaningful tasks. This reduces the number of elements in the model, making it less cluttered and easier to grasp at a glance.

**2. Focusing on the Big Picture:**

* By summarizing lower-level actions, event abstraction allows analysts to focus on the overall flow of the process.  They can see the key steps and decision points without getting bogged down in minute details.

**3. Improved Interpretability:**

* Complex process models can be overwhelming. Abstraction helps translate the technical details of the event log into a more human-readable format.  This makes it easier for stakeholders without technical expertise to understand the process.

Here are some techniques for applying event abstraction:

* **Pattern-based abstraction:** Identify frequently occurring sequences of events and represent them as a single, higher-level activity.
* **Clustering:** Group similar events based on pre-defined criteria, such as data used or system involved. 
* **Manual abstraction:**  Domain experts can define rules to combine specific events into more meaningful tasks.

**Overall, event abstraction helps create a more concise and user-friendly representation of the process, allowing for better analysis, communication, and ultimately, process improvement.**
