11 Best Named Entity Recognition Tools and Services

Article by Hengtee Lim | November 01, 2019

Named entity recognition (NER) tools play a major role in modern technology and information systems. You’ll find them everywhere, from content classification and e-commerce recommendations to social-media analytics and search engine optimization.

Although there’s no shortage of quality NER services available online, every project is unique. The best way to meet the specific goals of your project is with a custom dataset, annotated specifically for your purposes. Just how easy or difficult this is depends on the size of your project. While some projects can be done by yourself, others will require small groups or even whole teams.

It can be difficult to know which service best suits your circumstances. And that’s where our list of NER tools comes in. We’ve compiled a list of 11 entity annotation & NER tools and services. So whether your project is big or small, long or short, single language or multilingual, we hope this list helps you find the service you’re looking for!
