How Associa transforms doc classification with the GenAI IDP Accelerator and Amazon Bedrock

This can be a visitor publish co-written with David Meredith and Josh Zacharias from Associa.

Associa, North America’s largest group administration firm, oversees roughly 7.5 million householders with 15,000 workers throughout greater than 300 department places of work. The corporate manages roughly 48 million paperwork throughout 26 TB of knowledge, however their present doc administration system lacks environment friendly automated classification capabilities, making it troublesome to arrange and retrieve paperwork throughout a number of doc varieties. Each day, workers spend numerous hours manually categorizing and organizing incoming paperwork—a time-consuming, error-prone course of that creates bottlenecks in operational effectivity and probably ends in operational delays and lowered productiveness.

Associa collaborated with the AWS Generative AI Innovation Heart to construct a generative AI-powered doc classification system aligning with Associa’s long-term imaginative and prescient of utilizing generative AI to realize operational efficiencies in doc administration. The answer routinely categorizes incoming paperwork with excessive accuracy, processes paperwork effectively, and supplies substantial value financial savings whereas sustaining operational excellence. The doc classification system, developed utilizing the Generative AI Clever Doc Processing (GenAI IDP) Accelerator, is designed to combine seamlessly into present workflows. It revolutionizes how workers work together with doc administration programs by lowering the time spent on guide classification duties.

This publish discusses how Associa is utilizing Amazon Bedrock to routinely classify their paperwork and to assist improve worker productiveness.

Resolution overview

The GenAI IDP Accelerator is a cloud-based doc processing answer constructed on AWS that routinely extracts and organizes info from varied doc varieties. The system makes use of OCR know-how and generative AI to transform unstructured paperwork into structured, usable information whereas scaling seamlessly to deal with excessive doc volumes.

The accelerator is constructed with a versatile, modular design utilizing AWS CloudFormation templates that may deal with various kinds of doc processing whereas sharing core infrastructure for job administration, progress monitoring, and system monitoring. The accelerator helps three processing patterns. We use Sample 2 for this answer utilizing OCR (Amazon Textract) and classification (Amazon Bedrock). The next diagram illustrates this structure.

We optimized the doc classification workflow by evaluating three key elements:

• Immediate enter – Full PDF doc (all pages) vs. first web page solely
• Immediate design – Multimodal prompting with OCR information (utilizing the Amazon Textract analyze_document_layout) vs. doc picture solely
• Mannequin selection – Amazon Nova Lite, Amazon Nova Professional, Amazon Nova Premier, and Anthropic’s Claude Sonnet 4 on Amazon Bedrock

This complete analysis framework helped us determine the configuration that delivers the best accuracy whereas minimizing processing inference prices for Associa’s particular doc varieties and operational necessities. The analysis dataset consists of 465 PDF paperwork throughout eight distinct doc varieties. The dataset contains some samples recognized as draft paperwork or e-mail correspondences. These samples are categorized as doc kind Unknown on account of inadequate classification standards. The distribution of doc varieties throughout courses is unbalanced, starting from 6 samples for Insurance policies and Resolutions to 155 samples for Minutes.

Analysis: Immediate enter

We began our preliminary analysis utilizing full PDF paperwork, the place all pages of a PDF have been used as enter to the immediate for classification. The next desk exhibits the accuracy for full PDF classification utilizing Amazon Nova Professional with OCR and picture. We noticed a median classification accuracy of 91% contemplating the completely different doc varieties with a median value of 1.10 cents per doc.

Utilizing full PDF for doc classification demonstrates an accuracy of 100% for Certificates of Insurance coverage and 95% for Minutes. The system appropriately categorized 425 out of 465 paperwork. Nonetheless, for the Unknown doc kind, it achieved solely 40% accuracy, appropriately classifying simply 8 out of 20 paperwork.

Subsequent, we experimented with utilizing solely the primary web page of a PDF doc for classification, as proven within the following desk. This method improved general accuracy from 91% to 95% with 443 out of 465 paperwork categorized appropriately whereas lowering classification value per doc from 1.10 cents to 0.55 cents.

Other than improved accuracy and lowered value, the first-page-only method considerably improved Unknown doc classification accuracy from 40% to 85%. First pages usually include essentially the most distinctive doc options, whereas later pages in drafts or e-mail threads can introduce noise that confuses the classifier. Mixed with quicker processing speeds and decrease infrastructure prices, we chosen the first-page-only method for the following evaluations.

Analysis: Immediate design

Subsequent, we experimented on immediate design to judge whether or not OCR information is important for doc classification or simply utilizing the doc picture is adequate. We evaluated by eradicating the OCR textual content extraction information from the immediate and solely utilizing the picture in a multimodal immediate. This method removes the Amazon Textract prices and depends totally on the mannequin’s understanding of visible options. The next desk exhibits the accuracy for first-page-only classification utilizing Amazon Nova Professional with solely picture.

The image-only classification method demonstrates comparable points as the total PDF classification method. Though this methodology achieves an general accuracy of 93%, for Unknown doc varieties, it may classify solely 10 out of 20 paperwork appropriately with 50% accuracy. The next desk summarizes our analysis of an image-only method.

The image-only method removes OCR prices however reduces general accuracy from 95% to 93% and Unknown doc accuracy from 85% to 50%. Correct Unknown doc classification is vital for downstream human evaluate and operational effectivity at Associa. We chosen the mixed OCR and picture method to keep up this functionality.

Analysis: Mannequin selection

Utilizing the optimum configuration of first-page-only classification with OCR and picture, we evaluated completely different fashions to determine an optimum stability of accuracy and price, as summarized within the following desk. We concentrate on general classification efficiency, classification of unknown paperwork, and per-document classification prices.

General classification accuracy ranged from 95–96% throughout the fashions, with variation in unknown doc kind efficiency. Certificates of Insurance coverage, Plat Map, and Minutes achieved 98–100% accuracy throughout the fashions. Anthropic’s Claude Sonnet 4 achieved the best unknown doc accuracy (95%), adopted by Amazon Nova Premier (90%) and Amazon Nova Professional (85%). Nonetheless, Anthropic’s Claude Sonnet 4 elevated classification value from 0.55 cents to 1.21 cents per doc. Amazon Nova Premier achieved one of the best general classification accuracy at 1.12 cents per doc. Contemplating the trade-offs between accuracy and price, we chosen Amazon Nova Professional because the optimum mannequin selection.

Conclusion

Associa constructed a generative AI-powered doc classification system utilizing Amazon Nova Professional on Amazon Bedrock that achieves 95% accuracy at a median value of 0.55 cents per doc. The GenAI IDP Accelerator facilitates dependable efficiency scaling to excessive quantity of paperwork throughout their branches. “The answer developed by AWS Generative AI Innovation Heart improves how our workers handle and manage paperwork, and we foresee important discount of guide effort in doc processing,” says Andrew Brock, President, Digital & Expertise Providers & Chief Info Officer at Associa. “The doc classification system supplies substantial value financial savings and operational enhancements, whereas sustaining our excessive accuracy requirements in serving residential communities.”
