Text Classification

Text Classification is the task of categorizing text into predefined labels or classes. It is a key technique in natural language processing (NLP) that enables machines to analyze and interpret textual data by assigning relevant categories based on the content and context of the text. This process can be applied in various domains such as spam detection, sentiment analysis, topic labeling, and intent recognition.

Text classification typically involves several steps, including data preprocessing (such as tokenization, stemming, and removing stop words), feature extraction (converting text into numerical representations), and training machine learning algorithms to recognize patterns in the data. Common algorithms used for text classification include support vector machines, decision trees, and deep learning methods like recurrent neural networks (RNNs) and transformer-based models.

The effectiveness of text classification depends on the quality of the training data, the choice of features, and the learning algorithms used. Overall, text classification is fundamental for automating tasks that involve understanding and organizing large volumes of text.
