Text Classification: Categorizing Text Documents

The process of giving predefined categories to free-text documents is known as text categorization (also known as text classification). It has significant applications in the real world and can offer conceptual perspectives of document collections.

Though the text is a very rich source of information, it can be quite challenging to draw relevant conclusions from it. Due to the advanced technologies in machine learning and natural language processing, sorting data has now become a mere cakewalk. 

What is Text Classification?

Machine learning methods such as text categorization classify unstructured text into a number of predetermined categories. Almost any type of text, including documents, medical studies, files, and information found on the internet, can be organized, structured, and classified using text classifiers.

For instance, new content can be categorized by themes, support tickets can be categorized by urgency, chat conversations can be categorized by language, brand mentions can be categorized by mood, and so forth.

One of the core functions of natural language processing is text classification, which has numerous applications in the areas of sentiment analysis, topic categorization, spam detection, and intent detection.

Why is Text Classification Important?

According to research, the text is one of the most prevalent forms of unstructured data and makes up about 80% of all information. The fact that text is messy makes it difficult and time-consuming to analyze, analyze, organize, and filter through text data, which prevents most businesses from taking full use of it.

Machine learning is used in this situation to classify text. With the help of text classifiers, businesses can quickly and efficiently organize all kinds of relevant text, including emails, legal documents, social media posts, chatbot conversations, surveys, and more.

By automating business procedures, businesses can save time on text data analysis, and they can also make data-driven judgments.

Why Use Machine Learning for Text Classification?

Some of the top reasons to use ML for text classification include the following:

  1. Scalability

It takes a long time and is much less accurate to analyze and organize things manually.

Machine learning can quickly and cheaply analyze countless emails, comments, surveys, and other types of data. Tools for text classification can be adjusted to suit any business’ demands, no matter how big or small.

  1. Real-time Analysis

Certain urgent situations demand that businesses recognize them as soon as possible and act right away (e.g., PR crises on social media). For you to quickly identify important information and take immediate action, machine learning text categorization can continuously and in real-time monitor brand mentions.

3.   Consistent Criteria

Due to distractions, exhaustion, and boredom, as well as human subjectivity, human annotators make mistakes when classifying text data, which leads to varying standards. The same set of standards and criteria are used for all data and outcomes when using machine learning, though. An unmatched level of accuracy is achieved once a text classification model has been appropriately trained.
