In the digital age, data is the backbone of decision making, as organizations are constantly seeking ways to efficiently access and extract insights from the massive amounts of data they accumulate. Traditional search methods have served us well, but chat-based solutions have ushered in a new era of search capabilities.

Imagine typing a question about your company’s financial performance and receiving accurate and contextually relevant results. What about finding a favorite pair of running shoes without having to go through dozens of filters on a website? Or even booking a cruise without browsing many pages and clicking on all the options?

That’s the power of chat-based search, and generative AI is at the heart of this innovation. Technologies like Amazon Bedrock empower businesses to build intelligent chat-based interfaces that allow employees to interact with company data conversationally.

Implementing and Optimizing Chat-Based Search

Implementing chat-based search requires a strategic approach. As Slalom experts shared in the webinar, the following best practices ensure successful deployment:

  • Understand user needs: Understand your users’ specific needs and preferences. What questions are they likely to ask? What pain points can chat-based search alleviate?
  • Design natural conversations: Craft conversational interfaces that mimic natural human interactions. The goal is to create a seamless experience that feels intuitive and effortless.
  • Data preparation: Ensure your data is structured and organized, as this directly impacts the accuracy of search results. Clean, well-organized data enhances the effectiveness of chat-based search models.
  • Continuous learning: Chat-based search systems can learn and improve over time. Implement mechanisms to gather user feedback and iteratively refine the system based on user interactions.

AWS Options for Retrieval-Augmented Generation

What’s made this new era of search possible is a groundbreaking innovation known as retrieval-augmented generation (RAG), which seamlessly merges two components—retrieval and generation—to create a remarkably sophisticated and functional search experience.

At its core, RAG architecture leverages the strength of retrieval models to swiftly pinpoint relevant documents or pieces of information from a vast corpus. This initial retrieval stage ensures the system can quickly identify items the user seeks with natural-language inputs.

Here’s where the magic happens: the generation component of RAG architecture not only returns the items but, through prompt engineering and configuration, allows an organization to guide the user with responses that read and feel natural, akin to an authentic conversation between humans. This transformative process bridges the gap between raw data and user-friendly insights, elevating the conversational search experience.

In essence, RAG architecture enables users to engage with search systems conversationally. It empowers users to pose questions, seek clarification, and obtain valuable information effortlessly, mirroring the experience of interacting with an expert. Below, you will see an example of a RAG minimum viable product (MVP) solution architecture.

Whether employed for ecommerce site search to enhance customer exploration or for enterprise search to streamline employee retrieval of information within complex datasets, RAG architecture is an avenue for more intuitive, informative, and engaging interactions. This approach is reshaping how we navigate and extract value from the information available to us.

When deploying a chat-based search application, several architectural decisions exist apart from the frontend design, embeddings, and data storage. Focusing on the foundation model (FM) and whether to use a fully managed API service or self-hosted model endpoint is a big part of the decision-making required to build RAG architecture.

With AWS, you have the option of Amazon Bedrock for a fully managed FM API service, or the self-hosted models available within Amazon SageMaker, specifically Amazon SageMaker Jumpstart. Each approach has its strengths and considerations.

The selection of the vector database is also of utmost importance when considering the RAG architecture, as it plays a critical role in efficiently storing and retrieving high-dimensional representations of textual data. At a high level, the RAG-based architecture consists of two key components: a retriever and a generator.

The retriever leverages vector databases to swiftly search and retrieve pertinent passages or documents from a vast corpus of text, based on user queries. These retrieved passages then serve to enhance the generator’s knowledge, providing valuable context and information for generating accurate and contextually relevant responses. Consequently, this improved retrieval process improves the quality of responses generated by the RAG model, thereby enhancing the overall effectiveness and user-friendliness of the chat-based application.

Let’s delve into a comparative analysis to help you make an informed choice that aligns with your project’s requirements.

Amazon Bedrock FM API Service: The Power of Managed Simplicity

Amazon Bedrock makes FMs available through an API, which presents a compelling proposition for those seeking streamlined accessibility to advanced AI capabilities. With a fully managed service, you’re relieved from the complexities of model deployment, infrastructure management, and scalability concerns.

  • Data security: With the API-based access to third-party providers, security is always key to ensure the data is not being shared. With Amazon Bedrock, your data is encrypted at rest and in transit and developers can establish private connectivity between virtual private clouds (VPCs) and the Amazon Bedrock service using VPC endpoints

Leveraging Amazon Bedrock Knowledge Base

With the new knowledge bases capability in Amazon Bedrock, developers have an end-to-end managed service to easily enable RAG workflows for their generative AI applications on AWS, unlocking new possibilities for creating intelligent chat-based solutions.

Knowledge bases simplify the process of making company data accessible to Amazon Bedrock agents to efficiently retrieve and incorporate relevant contextual information from company data sources into the input prompts for foundation models, which prevents the need to continuously retrain models each time new data is added. This augmented data provides more focused context that improves the relevance, accuracy, and specificity of model completions.

Developers only need to specify the location of their data (for example, company documents stored in Amazon S3), select an embedding model such as Amazon Titan embeddings, and provide details of their vector database. Amazon Bedrock then handles ingesting the data, generating vector embeddings, populating the vector database, and keeping embeddings updated as new data is added.

For vector databases, developers can leverage fully managed options like vector engines for Amazon OpenSearch Serverless, Redis Enterprise Cloud, and Pinecone, which removes overhead of deploying and managing that infrastructure. Thus, pairing knowledge bases with Amazon Bedrock’s managed agents streamlines prompt engineering by automatically retrieving and integrating relevant data into the input based on user queries, as depicted below.

As a result, Amazon Bedrock knowledge bases eliminate many complex components of enabling RAG. Companies no longer have to build custom pipelines for data ingestion, embedding generation, and database population. The automation and abstraction provided by the knowledge base lets developers focus on the application logic and prompt engineering while leveraging RAG’s benefits. This streamlines deploying generative AI that dynamically taps into up-to-date company data to boost relevance.
