Component description
How the Text Classification component works
Classification Component
The Classification component is designed to perform text classification, sorting incoming text into one or more user-defined categories. This is particularly useful in AI workflows where automatic categorization, routing, or labeling of incoming messages or documents is required.
What the Component Does
At its core, this component takes an input text and classifies it according to a set of categories and their optional descriptions. It supports integration with conversational history and allows customization of the classification logic using various configuration options. The component is model-agnostic and can leverage any compatible language model, including lightweight models, making it flexible and efficient for a variety of use cases.
Key Inputs
| Input Name | Type | Required | Description |
|---|---|---|---|
| Input Text | Message | Yes | The main text to be classified. |
| Chat History | InMemoryChatMessageHistory | No | Previous conversation messages to provide context and improve classification accuracy. |
| LLM (Model) | BaseChatModel | No | Specifies which large language model to use for the classification. |
| Categories | Data (Nested Dict) | Yes | A dictionary of category names and optional descriptions to define what the text should be classified into. |
| Classification Type | Dropdown (str) | Yes | Choose how many categories can be selected: One or More, Zero or More, One Only, Zero or One. |
| Custom System Message | Message | No | An optional system prompt to further guide the classification model’s behavior. |
| Tool Description | str (multiline) | No | A description for the tool, helpful when used within agent frameworks. |
| Tool Name | str | No | Optional, for referencing this tool in agent-based workflows. |
| Verbose | bool | No | Option to enable verbose output for debugging or transparency. |
