GetTopCategories(IList<string>, string, int, bool, CancellationToken)

Classifies the specified plain text into up to a specified maximum number of categories.

public List<int> GetTopCategories(IList<string> categories, string content, int maxCategories, bool normalize = true, CancellationToken cancellationToken = default)

Parameters

categories IList<string>

A list of predefined category names.

content string

The plain text to be classified.

maxCategories int

The maximum number of top categories to return.

normalize bool

Optional. Specifies whether input parameters should be normalized. The default is true.

cancellationToken CancellationToken

Examples

// Synchronous usage:
var categories = new List<string> { "finance", "travel", "entertainment", "politics", "technology" };
string text = "The government unveiled a new technology policy impacting the finance sector.";

// Returns the top 3 categories:
IList<int> topCategories = categorization.GetTopCategories(categories, text, 3);

Console.WriteLine("Top categories:");
foreach (var index in topCategories)
{
    Console.WriteLine(categories[index]);
}

cancellationToken CancellationToken

A CancellationToken used to cancel the operation.

Returns

List<int>

A list of zero-based indices representing the top matching categories for the given image.

Exceptions

InvalidModelException

Thrown if the underlying model does not support vision when an image is provided.
