10 of The Best Text Mining APIs to Analyze Business Data

Text mining also referred to as text analysis, uses AI technology to find meaningful information in large volumes of unstructured text. 

This means that you can start getting value from your data ‒ like customer support tickets and social media mentions ‒ by sorting batches of text by topic, sentiment, urgency, language, and intent. Or extracting keywords, entities, and other relevant insights. 

Try out this sentiment analysis analyzer to see how quickly it sorts your text. 

The most popular way to get started with text mining is by integrating APIs into your existing tools. Instead of building software entirely from scratch, APIs enable you to harness the power of ready-made tools. You can choose from open-source or SaaS software, depending on skills, budgets, and timing.

While open-source software is free, flexible, and provides all kinds of resources, you’ll need a team of devs that are well versed in machine learning to use open-source APIs. SaaS tools, on the other hand, give you access to powerful text mining solutions that are fast and simple to implement with just a few lines of code: no programming skills or machine learning expertise needed.

Google Cloud NLP

Google Cloud Natural Language Processing provides a suite of AI and machine learning solutions to analyze unstructured text. 

Using the Cloud NLP API, developers can understand topics and sentiment in customer conversations, analyze syntax (like tokens, dependency, and part-of-speech), and identify entities across documents. 

To work with all these features, you can choose to use one of the powerful pre-trained models available, or build a custom machine learning model ‒ even with little machine learning expertise ‒ with the AutoML Natural Language tool. 

Pricing: there’s a free plan available. Pricing is subject to the features you use. 

Microsoft Azure

Microsoft Azure’s Text Analytics API is a suite of services built with Microsoft’s powerful machine learning algorithms. The API focuses on four main tasks: sentiment analysis, language detection, named entity recognition, and key phrase extraction. 

No training data or further customization is required to use these models, and you can get started even if you’re a programming novice. In fact, there are tutorials available, showing how you can use the API depending on your programming level.

Pricing: there’s a free plan available. The Standard Plan starts at $74.71/month and it’s based on the number of transactions.

Best Open-Source APIs

  1. NLTK
  2. SpaCy
  3. PyTorch
  4. Scikit-learn
  5. TensorFlow

Natural Language Toolkit (NLTK)

NLTK is the leading library for text mining in Python. With a focus on research and education, this library offers a wide variety of resources ‒ like algorithms, datasets, pre-trained models, and useful documentation ‒ that makes it perfect for those who want to get hands-on experience in text analysis. 

NLTK presents all available methods to solve specific text mining tasks, like topic classification or named entity recognition, and lets you decide which one delivers the best results. However, using this library is not ideal for tackling complex projects or dealing with large amounts of data. 

A series of APIs are available for NLTK, to support tasks like sentiment analysis, stemming & lemmatization, tagging, and more.

SpaCy 

SpaCy is a Python library for text mining with industrial-strength capabilities. It’s super fast, supports large-scale datasets, and excels at preparing text for deep learning. 

In this library, you’ll find pre-trained models for various tasks like text classification, named entity recognition, tagging, and dependency parsing. All of it, accessible through a simple and nicely documented API 

PyTorch

PyTorch is an open-source library for machine learning, developed by Facebook. It’s excellent for building deep learning models for machine translation, tagging, classification, and other text mining tasks, as well as for computer vision. Entirely integrated with Python, this library is easy to use and, therefore, a great option for beginners. Also, it comes with several pre-trained models.

The PyTorch API is a big favorite among academics and researchers because it’s simple, flexible, and powerful.

Scikit-learn

Scikit-learn is a popular machine learning library for Python. It hosts simple text mining tools to perform tasks like classification, regression, clustering, and more. It’s easy to use, versatile, and supported by a strong community. 

You can access all its functionalities through a well-documented and consistent API. Since it has an easy learning curve, Scikit-learn is great for embarking on your first text analysis project, although it’s not very useful for deep learning techniques.

TensorFlow

TensorFlow is a powerful open-source library for machine learning designed by Google. Primarily used for deep learning, it supports advanced text classification, summarization, tagging, and speech recognition tasks. Since it gives you the capacity to analyze data on a huge scale, large companies choose TensorFlow to build their models.

TensorFlow’s APIs are available in various programming languages, although the Python API is the easiest to use. TensorFlow has a steep learning curve, so it’s not the best option for beginners.

Final Note

With text mining tools, companies can gain powerful insights from written data and use them to create customer-centric experiences and increase productivity in the workplace.
