Property AllowUnknownCategory

Namespace

LMKit.TextAnalysis

Assembly

LM-Kit.NET.dll

AllowUnknownCategory

Gets or sets a value indicating whether the categorization engine can identify when content does not match any of the predefined categories. If set to true, the engine returns -1 (for single-category methods) or an empty list (for multi-category methods) when no suitable category is identified. If set to false, the engine always assigns the content to the nearest matching category, even if confidence is low.

public bool AllowUnknownCategory { get; set; }

Property Value

bool

true to enable handling of unknown categories; otherwise, false. The default value is false.

Examples

using LMKit.Model;
using LMKit.TextAnalysis;
using System;
using System.Collections.Generic;

class Example
{
    static void Main()
    {
        LM model = LM.LoadFromModelID("llama-3.1");
        Categorization categorization = new Categorization(model);

        categorization.AllowUnknownCategory = true;

        var categories = new List<string> { "sports", "technology", "health" };
        string text = "An unidentified creature was spotted in the forest.";

        int index = categorization.GetBestCategory(categories, text);

        if (index == -1)
        {
            Console.WriteLine("The content did not match any known categories.");
        }
        else
        {
            Console.WriteLine($"Best Category: {categories[index]}");
        }

        Console.WriteLine($"Confidence: {categorization.Confidence:P1}");
    }
}

Remarks

Enable this property when it is critical to explicitly handle content that does not clearly match any provided category. Use the Confidence property after categorization to assess reliability of results.
