Abstract:

This research investigates the application of Large Language Models (LLMs) to augment conversational agents in process mining, aiming to tackle its inherent complexity and diverse skill requirements. While LLM advancements present novel opportunities for conversational process mining, generating efficient outputs is still a hurdle. We propose an innovative approach that amend many issues in existing solutions, informed by prior research on Natural Language Processing (NLP) for conversational agents. Leveraging LLMs, our framework improves both accessibility and agent performance, as demonstrated by experiments on public question and data sets. Our research sets the stage for future explorations into LLMs' role in process mining and concludes with propositions for enhancing LLM memory, implementing real-time user testing, and examining diverse data sets.

Summary Notes

Making Process Mining User-Friendly with Conversational AI

The world of data analytics is constantly advancing, and process mining has become essential for businesses looking to improve their operations.

However, the complexity of process mining often requires a deep understanding of data models and specific domains, making it challenging for non-experts to navigate, particularly in critical sectors like healthcare and manufacturing.

This is where the integration of Large Language Models (LLMs) into conversational AI comes into play, offering a simpler way to access complex data insights through easy-to-use conversational interfaces.

The Challenge at Hand

Process mining focuses on analyzing event data to identify operational bottlenecks, compliance risks, and optimization opportunities.

Despite its potential, the technical nature of current tools can be a barrier for many. LLMs, like GPT-4, promise a solution by allowing users to interact with complex datasets through natural language, eliminating the need to understand data querying languages or process mining techniques.

However, using LLMs effectively requires specialized prompt engineering.

A User-Friendly Framework for Conversational AI in Process Mining

Framework Architecture Overview:

• Task-Oriented Design: The framework uses LLMs to create tasks like generating SQL queries from user questions, ensuring accurate and relevant insights.
• Challenges and Solutions:
• Integrates domain-specific knowledge to accurately understand industry or process terms.
• Develops mechanisms to correct malformed SQL queries and handle complex multi-query questions.
• Adapts to diverse data models to avoid incorrect assumptions.

Experimental Evaluation Insights:

• Effectiveness: LLMs accurately understood and responded to user queries 77% of the time, with 68% of responses being correct or partially correct.
• Areas for Improvement: Enhancements in response categorization were identified, helping to better understand the accuracy of the answers provided.

Looking Forward: Impacts and Future Directions

The fusion of conversational AI with process mining is more than just a technical innovation; it's changing how businesses interact with data. This new approach lowers the barrier to entry for using complex event data, enabling insights at all organizational levels.

Future Directions Include:

• External Memory for LLMs: Adding the ability for conversational agents to remember past interactions and user preferences.
• Advanced Prompt Engineering: Creating more sophisticated prompts to improve LLM response accuracy and relevance.
• Real-Time User Testing: Continuously refining the conversational interface through live user feedback to meet the diverse needs of enterprises.

Conclusion

Incorporating LLMs into process mining significantly broadens the accessibility of advanced data analytics.

This advancement not only makes process mining tools more efficient but also empowers individuals across an organization to directly engage with their process data.

As this technology evolves, it promises to unlock deeper insights, fostering innovation and optimization across industries.

Enterprises embarking on this journey are not just adopting a new tool but are leading a shift towards inclusive, data-driven decision-making, setting the stage for operational excellence and a competitive edge in the market.
