What is Text Classification in NLP and What are the Methods?

NLP in machine learning and AI development is playing a bigger role in understating the style of speech communication between humans and make it comprehensible to machines. And text classification plays an important role to classify sentences or text documents into a defined categories while integrating the NLP into machines.

Text classification for NLP is done to filter and organize the useful data from various sources like emails, chat, web pages, social media, surveys and many more. These texts are available in unstructured formats and getting the key information is very hard and time consuming.

But with the text classification and text annotation data is classified into a structured data sets making it in usable formats for algorithms in natural language processing (NLP) for AI or machine learning based model like chatbot to mimic like humans communicate.

Though, text classification provides a good framework to become familiar with textual data processing without lacking interest, either. As there are multiple applications of text classification like sentiment analysis and spam detection services.

Methods of Text Classification

Manual and automatic are two ways of text data classification executed as per the resource availability and requirements. In automated text classification, AI or machine learning based tools and techniques are used to classify the texts at faster rate and cost-effectively.

While on the other hand, manual text classification is little time taking but provides more qualitative work to supply the accurate training data for NLP. However, using the combination of both human-powered manual and automatic text classification can provide well-organize and classified data sets to make the NLP more effective and predictive in real-life use.

Cogito is providing the data classification solution for text, videos, audio and images with annotation and labeling to make the data recognizable for computer vision or machine use. From classifying texts to and annotate, Cogito offers a complete data classification and natural language processing annotation solution for machine learning companies at best level of pricing helping them to develop a prizewinning AI-based model.
