Day 2 Keynote - Evolution of Moody's Search: Embracing Cloud-Native Solutions to Enable AI-Powered Product

This presentation will delve into Moody’s transformative journey in search architecture, showcasing a significant shift from traditional servers running legacy SOLR software to a cloud-native AWS OpenSearch framework. The transition not only addresses the need for high availability and scalability but also marks a departure from the conventional monolithic relevance system, Lucidworks, towards custom designed in-house AWS serverless relevance architecture. Collaborating closely with the OpenSource Connections (OSC) team, Moody’s is progressing towards establishing search as a platform, aiming to enhance cross-products usability seamlessly, including for AI use cases.

To ensure the relevancy of search results, Moody’s has incorporated Quepid into its framework, offering a robust solution for analyzing search queries, understanding user intent, and fine-tuning search algorithms. This component plays a pivotal role in the ongoing efforts towards search testing and validation harness, ultimately enhancing the quality of search results across Moody’s systems.

Gen-AI initiatives at Moody’s are equally noteworthy, focusing on the implementation of semantic-based search powered by OpenSearch as a vector store. This initiative is complemented by an AWS Glue ingestion pipeline and the refinement of Vector embedding and chunking algorithms using ML Models. The culmination of these efforts serves as the backbone for Moody’s innovative Generative AI product, ‘Research Assistant,’ delivering a sophisticated and intelligent search experience enabling streamlined workflows and significant improvement for users to find ratings, research, and data more efficiently, helping translate those findings into valuable insights.
