Named entity recognition (NER) is a very important task in the field of natural language processing.
It can help to extract information from text, such as person names, place names, and organizations. In this article, we will compare 6 of the best named entity recognition APIs to help you choose which one is best suited for your project!
Introduction to Named Entity Recognition
Named entity recognition (NER) is a field of natural language processing (NLP). It’s the process of identifying and recognizing names, locations, and organizations in text.
A NER API can help you identify different entities within your data by providing contextually relevant information about them.
Named entities include:
- People
- Organizations
- Places * Locations * Areas of interest (e.g., sports teams)
Why Named Entity Extraction is Important
Named entity recognition is a crucial step in text analysis. It involves identifying the names of persons, organizations, locations, and other entities from unstructured text.
It helps you extract information from a document by assigning it to a category (person, organization, etc.) which improves accuracy and reduces errors.
Here are some key benefits of NER:
- Named entities help improve accuracy in natural language understanding by removing ambiguity from words during textual analysis. They also increase the precision rate as they can be considered as fixed values instead of being calculated based on some rules or heuristics.
- The extraction process requires training data which should contain examples with appropriate types of entities along with their context (e.g., name of person) so that we can train our model accordingly; this ensures that our model doesn’t make any mistakes while recognizing specific data point or type within its context (e.g., `John Smith`).
How To Use a Named Entity Recognition API
A good place to start is with the documentation for the API. Each of these services has its own documentation, but they all contain instructions on how to use their APIs and integrate them into your project.
Once you’ve got an account with one of these services, all you have to do is create an instance of the class in your code and then call one of its methods. For example, if we wanted to detect named entities from a string like “John Smith,” we might do something like this:
```python
import nlp_api as nltk
(text) = 'John Smith'Comparison of the Top 6 NER APIs
- IBM Watson NER API
- RapidAPI: NER API
- Amazon Comprehend NLP APIs
- Google Cloud Natural Language API (Natural Language Understanding)
- Microsoft Azure Machine Learning, Entity Framework Core Extensions Library for Entity Classification and Detection with Linear Regression
Conclusion
The takeaways from this article are:
- The need for NER isn’t just limited to the world of AI. It can be used in many other industries and fields, including healthcare, marketing, and journalism.
- There are a lot of different types of projects you can build using NER APIs. These include:
- Document classification
- Sentiment analysis
- Entity extraction
- Topic extraction
- Information retrieval
From the comparison table, it is evident that each NER API has its own features and services. Hence, careful consideration is needed in order to pick the right NER API for your project.

Now that you are aware of the 6 best-named entity recognition APIs, it is time to make a choice and start using them in your project. There are many options available for developers to choose from such as IBM Watson, Azure Cognitive Services, and Microsoft Cognitive Services.
Each of these platforms offers different features and services which can be used based on their requirements. The one we liked most was Microsoft’s NER API because of its ease of use and flexibility in terms of integration with other services like Bing search engine results or Bing web crawlers which makes the entire process very simple indeed!
