Introduction

In today's digital age, travel planning has become increasingly complex, with numerous options available for accommodations, transportation, and activities. To provide a more comprehensive travel assistance, our LLM-based service handling system requires integration with various third-party APIs. One such API is the Expedia Lodging API, which offers a vast array of accommodation-related services. In this article, we will explore the implementation of a new factory to integrate the Expedia Lodging API, enhancing our service's capabilities in the travel and accommodation sectors.

Background and Motivation

Our LLM-based service handling system currently integrates various third-party APIs, such as Ticketmaster for events. However, to provide a more comprehensive travel assistance, we need to expand our service's capabilities to include accommodation-related queries. The Expedia Lodging API offers a wide range of services, including hotel details, booking information, and rates. By integrating this API, our LLM will be able to handle accommodation-related queries effectively, making it a more valuable travel assistant.

Proposed Features

To implement the Expedia Lodging factory, we propose the following features:

Expedia Factory

The Expedia factory will be a new factory class that conforms to our existing abstract factory interface. This factory will be responsible for creating products that interact with the Expedia Lodging API. The factory will provide a standardized interface for creating products, making it easier to integrate with our existing LLM-based service handling system.

Expedia Product

The Expedia product will handle specific API calls to Expedia, such as fetching hotel details, booking information, and rates. It will parse natural language prompts to determine the appropriate API calls, similar to how our Ticketmaster integration works. The product will be designed to handle various types of accommodation-related queries, including:

Hotel Search: Find hotels near a specific location or with specific amenities.
Booking Information: Retrieve booking details, including room rates, availability, and cancellation policies.
Rate Comparison: Compare rates across different hotels or travel dates.

LLM Prompt Analysis

To effectively integrate the Expedia Lodging API, we need to enhance our LLM prompt analysis to include accommodation-related intents. This involves training or fine-tuning our LLM with prompts that are specifically geared towards lodging inquiries, such as:

Find hotels near me with free Wi-Fi: This prompt requires the LLM to identify the user's location and retrieve a list of hotels with free Wi-Fi in the area.
Show me pet-friendly hotels in New York for next weekend: This prompt requires the LLM to identify the user's location and retrieve a list of pet-friendly hotels in New York for the specified travel dates.

Create the Expedia factory class: This class will conform to our existing abstract factory interface and provide a standardized interface for creating products that interact with the Expedia Lodging API.
Implement the Expedia product: This product will handle specific API calls to Expedia, including fetching hotel details, booking information, and rates. It will parse natural language prompts to determine the appropriate API calls.
