Fault-Tolerant Customer Lookup from Unstructured Data

This Data App demonstrates how the M|Box Table Indexing nodes can be combined with LLMs to find records in large datasets using unstructured text data.

The Customer Lookup Data App:

  • Loads a dataset containing 100,000 customer records, including names, phone numbers, addresses, and other attributes.

  • Builds a multi-field search index using the Table Indexer node to enable efficient and robust lookup across multiple customer attributes.

  • Uses the LLM-powered Document Entity Extractor component to extract relevant customer metadata from a user-provided email.

  • Matches the extracted information against the indexed dataset using the Table Index Matcher node to reliably identify the correct customer record.

M|Box's fast, fault-tolerant indexing enables reliable customer identification, even when the input contains typos, incomplete information, or minor inconsistencies introduced by user input or LLM-generated metadata.
