SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enables automated text classification and emotion/sentiment detection for text data using pre-trained models or custom-trained classifiers.

Core Features & Use Cases

  • Pre-trained models: sms-spam-filter, imdb-sentiment, emotion-detection for quick analytics.
  • Custom training and model management: train, evaluate, save, and load models for domain-specific tasks.
  • Practical applications: content moderation, customer feedback analysis, and spam detection across chat, email, and social media.

Quick Start

Use the classifier CLI to quickly classify text with a pre-trained model: classifier -r sms-spam-filter "You won a free iPhone! Click here now!" For sentiment analysis: classifier -r imdb-sentiment "This product exceeded my expectations"

Frequently Asked Questions about classifier

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I classify text to detect spam in chat or email messages?

Text classification for spam detection uses the sms-spam-filter pre-trained model to automatically flag unwanted messages. You can run classifier -r sms-spam-filter "your text" to instantly categorize chat, email, or social media inputs.

Can I train a custom text classifier for domain-specific sentiment analysis?

Custom text classifier training allows you to build domain-specific sentiment models using the classifier train command. You can train, evaluate, save, and load custom models to accurately analyze customer feedback for your specific industry vocabulary.

What pre-trained models are available for emotion detection and sentiment analysis?

Pre-trained models for emotion detection and sentiment analysis include sms-spam-filter, imdb-sentiment, and emotion-detection. These models enable quick text analytics across short and long inputs without requiring custom training.

Does text classification work for both short chat messages and long feedback text?

Text classification supports both short and long text inputs for sentiment and emotion detection. The pre-trained and custom-trained models process varying text lengths to deliver accurate classification across customer feedback and chat data.

What is the best way to moderate user-generated content using automated text classification?

Automated text classification for content moderation uses pre-trained models to identify spam and detect emotions across social media inputs. The classifier CLI instantly evaluates text to filter inappropriate content and analyze customer feedback.

Do I need to install dependencies to run the classifier CLI for text classification?

The classifier CLI operates without external dependencies to perform text classification and emotion detection. You can immediately use commands like classifier -r <model> 'text' and classifier models to manage pre-trained and custom models.
