Top 5 Text Analytics APIs

Top 5 Text Analytics APIs

Text analytics helps you transform unstructured data, like social media conversations, into quantifiable and actionable insights. It involves two steps. First, you need to use text mining algorithms to understand and sort text. Then, you need to transform the results into data visualizations and reports that help you easily spot insights, trends, and patterns.

Thanks to text analytics, companies are able to understand and predict customer behavior, and make smarter business decisions. 

Using APIs built by SaaS tools like MonkeyLearn is the easiest way to get started. They even offer ready-to-use text analysis models, like this topic classifier for NPS feedback.

5. Lexalytics

Lexalytics is a text analytics platform consisting of different modular solutions: Salience, Semantria, Semantria Storage & Visualization (SSV), and semi-custom applications. 

Salience is an on-premise NLP tool oriented to data scientists looking to add NLP capabilities and custom machine learning models while having full access to the underlying technology. 

Semantria is a powerful cloud API for tasks like categorization, sentiment analysis, and entity extraction. These tools can all be combined with SSV to find trends in your data. Finally, you have semi-custom applications for specific data-based problems within your business. 

Top Open-Source Libraries for Text Analytics

Open-source libraries are a free and flexible way to build custom text analytics models. Developers can easily access them through APIs (mostly available in Python – the preferred language for NLP tasks), but you’ll need to be familiar with machine learning tasks. 

These are the best open-source libraries for text analytics:

  1. Scikit-learn | Simple and easy-to-use machine learning APIs
  2. NLTK | A favorite among students and researchers
  3. SpaCy | A neat, easy to use, and well-documented API
  4. TensorFlow | High-performance machine learning and deep learning

1. Scikit-learn

Scikit-learn is a simple and easy-to-use machine learning library in Python. It’s suitable for classification, regression, and clustering tasks, among others. One of the perks of this library is its versatility. It can be adapted to a variety of use cases. 

Access all of Scikit’s features, algorithms, and pre-built models via its clean and consistent API. If you are just getting started with text analytics, this library is a good fit.


NLTK is a popular Python library, well known among students and researchers. Here, you can find datasets, pre-trained models, an active forum, and an exhaustive suite of algorithms and tools to help you gain hands-on experience with text analytics.

Using the available text processing APIs, you can perform tasks like sentiment analysis, stemming and lemmatization, and named entity recognition. As NLTK shows all the possible algorithms for each task, you can try different methods to see which one works best for you. The downside is that this library has a quite steep learning curve and can be slow, especially if you have to work with large datasets.
