Study Notes
Amazon Comprehend Overview
- Amazon Comprehend is a fully managed, serverless service for natural language processing (NLP).
- It leverages machine learning to analyze text, extracting insights and relationships.
- It understands text language, identifying key phrases, places, people, brands, and events.
- Sentiment analysis is possible, determining the positive or negative tone of text.
- Text analysis includes tokenization and part-of-speech tagging (if needed).
- Text collections can be organized by topics.
Use Cases
- Analyze customer interactions (e.g., emails) to understand positive/negative experiences.
- Automatically categorize articles by topic.
Advanced Settings
- Custom Classification: Users define categories for documents (e.g., support requests, billing, complaints).
- Training data is placed in Amazon S3 and used to train a custom classifier.
- A custom classifier analyzes incoming documents (e.g., emails) and categorizes them based on the trained categories.
- Supports various document formats: text, PDF, Word, images.
Real-time and Batch Analysis
- Real-time: Analyze documents or emails as they arrive.
- Synchronous analysis: Allows processing multiple documents simultaneously.
- Asynchronous analysis: Ideal for larger batches.
Named Entity Recognition (NER)
- Comprehend automatically recognizes predefined entities like people, places, organizations, dates.
- Example text demonstrates NER in highlighting entities.
Custom Entity Recognition
- Users define custom entities relevant to their business (e.g., policy numbers, escalation phrases).
- Training involves providing examples of the custom entities.
- A custom entity recognizer is trained and used for specific searches in documents.
- Can be used with real-time or asynchronous analysis.
