How does a text analysis API work?

Text analysis APIs integrate with websites and apps to analyze and convert high-level information into machine-readable text format. The API documentation tells the API what to look for and how to implement function calls.

Finding actionable insights from data can take hours for business owners, whereas computers canunderstand binary data and can’t interpret high-level languages.

Artificial Intelligence (AI)-powered text analysis APIs automatically extract data to execute different types of data classification. These APIs are particularly helpful for sentiment analysis, opinion mining, keyphrase extraction, language detection, and Named Entity Recognition.

You can, for instance, use a text analysis API to read and evaluate customer testimonials, recognize customer emotions regarding your brand, and address negative feedback on time.

Who needs a text analysis API?

A text analysis API is useful for anyone evaluating large quantities of text, including businesses, developers, and customer success teams.

Sources that businesses analyze to find data insights include:

  • Emails
  • Online reviews
  • Support tickets
  • Product feedback
  • Social media posts
  • Customer survey responses
  • Online customer interactions

With text analysis APIs, you can gain insights without manually navigating millions of data points from various sources.

What to look for in a text analysis API

Text analysis APIs today offer many functions as text classifiers in Machine Learning. You should want a solution that does it all, so make sure to look out for:

Key phrase extraction

Identifying document themes requires you to extract key phrases, terms, keywords, and segments. Businesses use keyphrase extraction to spot main concepts and themes in unstructured texts.

Entity recognition

Named Entity Recognition (NER) or entity chunking, identifies and categorizes identity-related information across texts—such as people, places, companies, and more. This entity data extraction process helps you preprocess data efficiently and easily identify a wide variety of entities.

Social media sentiment extraction

Modern customers use social media to share product experiences and feedback with their peers. Choose a text analysis tool that analyzes social sentiment, emojis, posts, and hashtags to help you meet customer expectations.

Language detection

Businesses use Automatic Language Detection (ALD) to classify texts based on language changes, down to the word level. This feature helps companies ensure they can meet customers’ needs in their mother tongue. Plus, you can also monitor dialects for collecting speech data and slang usage for surveillance or new word discovery.

Opinion mining

Sentiment analysis or opinion mining helps you analyze customer opinions and sentiments. It uses computational linguistics and Natural Language Processing (NLP) to identify and extract positive, negative, and neutral opinions to inform business decisions.

Speed, customization, and accuracy

Companies need custom data processing environments to crunch unstructured text data and find insights faster. Also, ensure that the text analysis API of your choice can adopt machine-learned training for multi-language analysis.

Intuitive interface

Finally, you want a text analysis tool that you can learn quickly, with minimal instructions. Tools with intuitive interfaces offer enhanced data visualization dashboards for finding real-time data trends and performance metrics.

Choosing a text analysis API with these features is essential for insight extraction and informed decision-making.
