How to Use Text Annotations for Machine Learning?


This article has everything you want to know about machine learning text annotation.

Reading a line such as: “You nailed it.” A human can definitely comprehend the rich meaning behind this context as the person who is writing is appreciating someone for doing something amazing.

However, a natural language processing system will have trouble grasping the exact meaning of the sentence completely and may misinterpret it as a negative sentiment. Text annotations can help fix the misinterpretation, leading towards a more accurate meaning of the context.

Text annotation is the machine learning process to give meaning to blocks of text. Be it short phrases or long sentences, AI models do the work with the help of additional information via definitions, meaning, and its main intent.

Why is Machine Learning Text Annotation Important?

To impart the richness of human languages is the predominant reason why text annotation is necessary for NLP. Even though machines are becoming smart, Annotation feeds them the information to interpret human language and understand our perspective.

Currently, chatbots are the most popular application of NLP (natural language processing). Though chatbots offer interesting automated solutions, poorly functioning chatbots can be detrimental to the firm’s reputation, user experience, and eventually customer loyalty.

There are three types of text annotations:

  • Named Entity Tagging (NET) – used to assign labels to phrases or words within a text such as “actor or “city. They are used in chatbots, screening processes for hiring and recruiting people, medical records, etc.
  • Sentiment Annotation – helps in understanding the emotion behind the text – positive, negative, or neutral. They are used to understand customer insights, social media posts, and comments, etc.
  • Semantic Annotation – understand the user’s intent in specific descriptions such as industrial or banking jargon.

These Machine learning text annotations must be accurate and complete. Poor text annotations can cause the machine to show grammatical errors. With accurate annotated text data, the machine can communicate efficiently. This can save a lot of time, money, and effort in an organization and help them focus on other goals.

Even though human annotators can annotate text, almost the entire best quality machine learning annotations come from text annotation tools. These tools deliver excellent results from the ability to understand complex emotions to expert comments on high-tech topics.

That said, what should companies do when facing large-scale projects? Text annotation tools are an excellent solution to complete large-scale data annotation work.

Most companies are looking for human annotators for labeling text data. However, AI-based text annotation tools are way better when analyzing sentiment data because it is usually nuanced and depends on trending slang and other language usages.

Extensive text annotation and classification tools can help you deploy AI models faster and cheaper. The path you take depends on the difficulty of the problem that you are trying to solve, apart from the resources and financial commitment your company wants to provide.

Many companies offer powerful text annotation tools that ensure superior annotations. Be it sentiment annotation, semantic annotation, or named entity recognition, many companies that provide machine learning text annotations help you successfully run your Artificial Intelligence and Machine Learning projects.
