The logistics industry is undergoing a digital revolution driven by AI-powered automation. While traditional automation tools like Robotic Process Automation (RPA) streamline repetitive tasks, the next step is integrating them with conversational interfaces for a more intuitive user experience.
This article explores how Large Language Models (LLMs) can be leveraged to build chatbots that act as a user-friendly layer on top of existing automation technologies within logistics.
Despite their prevalence, there's a growing need to integrate APIs and RPAs into conversational automation systems. Task-oriented conversational automation, like chatbots and virtual assistants, represents the next step in user engagement and customer support, moving beyond basic Q&A tasks to include actionable steps. Incorporating APIs into these systems opens up numerous possibilities by enabling access to real-time data, performing complex tasks, and interfacing with external services as needed. Given that many business users lack technical expertise in software development and automation, task-oriented conversational systems address the primary barrier to adopting automation technologies.
One way to enhance the accessibility of automation technologies like RPA, especially unattended bots, is by encapsulating their API services within chatbots. Employing natural language for interactive automation can offer a more intuitive experience for business users, as conversational systems strive to communicate in a human-like manner. Traditionally, creating chatbots involves multiple steps including training an intent classifier, which necessitates expertise in machine learning, natural language processing, and domain-specific data from experts, Identification of the inputs and their data types (often called slots) required for invoking the API and, processing of the result of the API and providing next action recommendations.
LLMs with vast parameter sizes, ranging from millions to billions, have demonstrated promising outcomes in various natural language tasks, including intent recognition and language generation. These models are trained on trillions of tokens extracted from open-domain text sources. They have been used to enable a conversation for APIs in a few cases. However, when it comes to enterprise automation, specialized domain knowledge is often required, which is not inherently present in the data used for training these LLMs. Consequently, adjustments or additional contextual information are necessary to make these models relevant to specific domains or prompts. Unfortunately, many businesses, especially small and medium enterprises, face challenges in fine-tuning such models due to limited resources or expertise, making the process prohibitively expensive. Further, LLMs suffer from the problem of uncertain outputs and hallucinations with limited control over what is generated. In addition to that, there is the issue of the high cost of deployment that requires a lot of infrastructure (including GPUs) to scale.
To alleviate the above issues, we have created a human-guided process of authoring and wrapping API services as Digital Assistant/chatbot skills. This process is called the build step. The objective is to use LLMs in the build phase to assist the human to author the skills for the digital assistant. This is typically a one-time step for each automation. Subsequently, the system does not have to leverage LLMs while conversing with business users. Human-guided authoring of skills is a preferred approach until LLMs reach that level of maturity. It also provides a level of trust and indemnity to the client.
Our approach involves language generation using the meta-data from the OpenAPI specifications of the APIs. Harnessing the generative capabilities of LLMs offline during build step helps eliminate the run-time expenses associated with high-end hardware.
Challenges of Traditional Conversational Automation for Logistics
Despite the promise of conversational automation, developing chatbots tailored to complex logistics workflows presents unique challenges. Here's a closer look at the hurdles:
Introducing Human-guided LLMs for Building Conversational Interfaces
To address these challenges, we propose a human-in-the-loop approach that utilizes LLMs during the development phase to streamline chatbot creation for logistics tasks. This method marries the power of AI with human expertise, resulting in efficient and domain-specific chatbots.
Here's a breakdown of the process:
1. Offline LLM Support: During the initial setup, LLM capabilities are used offline to analyze the descriptions of logistics-specific APIs (Application Programming Interfaces) that connect the chatbot to backend functionalities. This analysis helps generate conversational elements like:

2. Human Review and Refinement: A human subject matter expert with deep logistics knowledge reviews the LLM-generated conversational elements. This expert ensures the accuracy, clarity, and domain-specificity of the prompts, questions, and suggestions. Their refinement tailors the chatbot's responses to the specific context of logistics workflows, preventing misunderstandings and ensuring smooth user interactions.
3. Conversational Interface Creation: The refined conversational elements are then used to build a chatbot interface that interacts with users through natural language. This interface can be integrated into various communication channels commonly used in logistics, such as warehouse management systems, enterprise resource planning (ERP) software, or standalone messaging applications.
Benefits for Logistics Professionals
This human-guided LLM approach offers a multitude of advantages for logistics professionals:
