Google Cloud Natural Language API

The Google Cloud Natural Language API provides powerful tools for analyzing and understanding text. It can perform tasks such as sentiment analysis, entity recognition, and syntax analysis, allowing developers to integrate advanced natural language processing capabilities into their applications.

• Supports multiple languages including English, Spanish, French, and more.
• Offers entity recognition to identify names, places, and other significant terms.
• Provides sentiment analysis to gauge the emotional tone of a text.
• Enables syntax analysis for understanding grammatical structure.

Step-by-Step Setup

1. Go to the Google Cloud Console.
2. Create a new project or select an existing one.
3. Enable the Natural Language API for your project.
4. Set up billing if required.
5. Create API credentials (API key or service account).

Example Code

Below is a simple Swift example of how to use the Google Cloud Natural Language API to analyze the sentiment of a text:

import Foundation

let apiKey = "YOUR_API_KEY"
let url = URL(string: "https://language.googleapis.com/v1/documents:analyzeSentiment?key=\(apiKey)")!

let text = "I love programming with Swift!"
let json: [String: Any] = [
    "document": [
        "type": "PLAIN_TEXT",
        "content": text
    ],
    "encodingType": "UTF8"
]

let jsonData = try! JSONSerialization.data(withJSONObject: json)

var request = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.httpBody = jsonData

let task = URLSession.shared.dataTask(with: request) { data, response, error in
    guard let data = data, error == nil else {
        print("Error: \(error?.localizedDescription ?? "No data")")
        return
    }
    let result = try! JSONSerialization.jsonObject(with: data, options: [])
    print(result)
}
task.resume()
