NLP at AWS scale — sentiment, entities, PII, and topics in seconds

AnalyticsSupportDeveloperAIAutomation

AWS Comprehend is Amazon's managed natural language processing service that reads your text and returns structured intelligence — sentiment scores, named entities, key phrases, dominant language, syntax trees, and PII flags — without requiring you to train or host any model. Connect it to Actionist and your agents gain the ability to classify support tickets by tone, redact sensitive data before it spreads, extract contract parties from uploaded PDFs, run topic modelling across thousands of documents overnight, and react to async job completions via EventBridge — all in plain language, all without touching the AWS console.

Eliminates manual work. Eliminates the manual reading, tagging, and routing of free-text inputs — support tickets, survey responses, contracts, and review corpora — that would otherwise require a human to categorise before any downstream action can be taken.

Support email sentiment triage, zero manual routing

When a support email arrives, the agent reads its sentiment and entity signals through AWS Comprehend, flags frustrated customers in under 10 seconds, and routes the ticket to the right queue — critical cases get a Slack alert to the team lead and a Google Calendar block for a callback, all before a human has opened their inbox.

FAQs

Questions about AWS Comprehend + Actionist

How do I connect AWS Comprehend to Actionist?
Open the Apps tab, find AWS Comprehend, and click Connect. The recommended path is MCP — Actionist's MCP server handles the AWS IAM credential handshake and scopes permissions to only the Comprehend actions your workflows need. If you prefer direct key management, choose API Token and provide your AWS Access Key ID, Secret Access Key, and target region.
Which AWS IAM permissions does the agent need?
For real-time operations — Detect* and Classify* — the agent needs comprehend:DetectDominantLanguage, comprehend:DetectSentiment, comprehend:DetectEntities, comprehend:DetectKeyPhrases, comprehend:DetectSyntax, comprehend:DetectPiiEntities, and comprehend:ClassifyDocument. For async jobs, add comprehend:StartDocumentClassificationJob, comprehend:StartSentimentDetectionJob, comprehend:StartEntitiesDetectionJob, and comprehend:StartTopicsDetectionJob. Scope the policy to the specific resources your workflows use.
Can the agent combine AWS Comprehend with other apps?
Yes — that is the primary design. A typical flow is: Gmail triggers on a new support email → the agent calls Analyse sentiment → if Negative confidence exceeds 0.85, it creates a ClickUp task and pings the support lead in Slack. Comprehend's structured output slots naturally into any downstream action: update a HubSpot contact, log a Notion entry, write a Google Sheets row, or post a Discord alert.
What are the most common use cases for AWS Comprehend agents?
Customer support routing by detected sentiment, PII redaction before sharing documents with vendors, named-entity extraction from contracts and invoices, key phrase clustering across survey responses, language detection for multilingual content routing, async topic modelling on large document corpora, and custom document classification using a trained Comprehend endpoint. Each maps to one or more actions the agent can call in plain English.
Does the agent support asynchronous Comprehend jobs?
Yes. The agent can start a Topics Detection, Sentiment Detection, Entities Detection, or Targeted Sentiment Detection job and then react when the job completes — via the 'Sentiment job completed' or 'Topics detection job completed' EventBridge triggers — rather than polling. This lets you run overnight batch jobs on large S3 corpora and pick up the results automatically when they finish.
How does the agent avoid processing the same document twice?
Track a job ID or a document hash in a lightweight store — a Google Sheets row, a Notion property, or a DynamoDB item — before submitting to Comprehend. On each trigger, the agent checks whether the ID already exists and skips resubmission if it does. For EventBridge-triggered flows, the event payload carries the job ID, so idempotency checks are straightforward.
What text size limits should I know about?
Real-time operations (DetectSentiment, DetectEntities, etc.) accept up to 5,000 UTF-8 bytes per call. For larger documents, split the text into chunks before calling the action, or use the async job actions (Start sentiment detection job, Start topics detection job) which accept documents stored in S3 with no per-document byte cap. Batch operations accept up to 25 documents per call, each up to 5,000 bytes.
Which languages does AWS Comprehend support?
Real-time sentiment, entity, and key phrase detection support Arabic, Chinese (Simplified and Traditional), English, French, German, Hindi, Italian, Japanese, Korean, Portuguese, and Spanish. Dominant language detection supports 100 languages. Syntax detection and PII detection are English-only. Custom classifiers and entity recognisers can be trained on any of the supported languages. Always check the AWS Comprehend documentation for the most current language matrix.
