Can your system tell “John Smith” apart from “John Smith”?
Organizations requiring identity intelligence increasingly face challenges due to complexity of matching names and entities across vast, multilingual, and constantly evolving datasets. Whether helping border security, combating financial crimes, or maintaining regulatory compliance, the accuracy of identity and entity resolution directly determines whether threats are detected, investigations succeed, and regulatory requirements are met. Yet, linguistic diversity, transliterations, inconsistent data formats, and legacy system limitations continue to create friction, leading to false positives, missed matches, and costly manual reviews. As customers ingest and analyze petabytes of unstructured and structured data in Amazon OpenSearch Service, the need for intelligent, scalable, and multilingual matching becomes increasingly important. This is where the integration of Babel Street (an AWS Partner) with OpenSearch Service provides a solution that helps organizations enhance precision, reduce noise, and accelerate insights from their high-volume data environments.
This post explores how combining Babel Street Match with OpenSearch Service provides a solution that helps your organization to handle large-scale, multilingual data.
The growing complexity of identity and entity resolution
As organizations ingest and analyze massive volumes of multilingual and inconsistently formatted data, accurately matching names and entities becomes increasingly difficult. Variations in spelling, transliterations, semantic differences, cultural naming conventions, and incomplete or noisy records can contribute to mismatches. These challenges are compounded by legacy systems, fragmented data pipelines, operational inefficiencies, and evolving regulatory requirements—especially in sectors where precision is a requirement.
Evaluating and enhancing identity in high-volume enterprise environments
Amazon OpenSearch Service is a fully managed, scalable search and analytics service that enables organizations to ingest, search, visualize, and analyze massive volumes of data in near real time. Built to handle structured and unstructured information from diverse sources, it powers use cases ranging from security analytics and log monitoring to enterprise search and advanced analytical applications.
Babel Street delivers risk intelligence trusted by organizations across government, defense, and the private sector. The offering combines access to vast volumes of multilingual data with advanced analytics to uncover hidden identities, secure vendor networks, and identify emerging risks with precision, speed, and scale. From national security to regulatory compliance and enterprise resilience, Babel Street provides the strategic advantage needed to stay ahead of risk, safeguard operations, and protect missions.
Babel Street Match, an offering from Babel Street incorporates advanced identity risk intelligence capabilities, which enhance the precision and reliability of screening processes. This advanced solution uses sophisticated matching techniques to verify identities and identify variations in personal data—including aliases, alternate spellings, and differences in biographical details, helping organizations separate legitimate individuals from potential threats. The ability to screen names, addresses, dates, and other identifiers across different scripts and languages helps reduce false positives and negatives, helps accurately detect critical risks with transparent scoring to meet compliance and audit requirements. Further, Babel Street Match streamlines screening workflows, reduces the burden of manual reviews, and elevates the accuracy of threat detection.
The following diagram shows the details of OpenSearch Service and Babel Street Match Plugin integration.
Babel Street Match integrates directly with the OpenSearch Service domain through a lightweight plugin that runs inside your own AWS account where you have full control of your data. The Match plugin sends encrypted match requests to Babel Street’s fully managed Match engine, where the core matching engine performs the entity-resolution logic. The results return to you in real time, enhancing your existing OpenSearch Service workflows with advanced name- and entity-matching capabilities. Meanwhile, Babel Street’s control plane handles licensing, monitoring, and AWS Marketplace integration behind the scenes, provides continuous validation, automated updates, and a seamless operational experience.

Customer Success Stories
Here’s how leading organizations are leveraging Babel Street Match and Amazon OpenSearch Service to solve real-world identity challenges:
- A European online brokerage faced AML (anti-money laundering) compliance challenges with its outdated name-matching system, which produced excessive false positives and couldn’t process longer multilingual names. After implementing Babel Street Match on OpenSearch Service, the firm achieved up to 70% better accuracy across 25 languages—significantly reducing manual work and speeding customer payments.
Babel Street Match Improves FI’s Name-Matching Accuracy by Up to 70% on OpenSearch - A major border agency struggled with an outdated screening system that flagged 15% of travelers as potential watchlist matches—overwhelming agents and creating long queues. After implementing Babel Street Match, false positives dropped dramatically (from 80,000 to just 100 in one test), hardware needs fell by 70%, and travelers with common names can now pass through faster. As one stakeholder put it: “Name matching is not our biggest problem anymore.”
