Top 10 Named Entity Recognition (NER) API

In this article, we will introduce our top 10 Named Entity Recognition (NER) APIs, how to choose and access the right engine according to your data.

What is Named Entity Recognition (NER)?

What does NER do?

Named Entity Recognition (NER) refers to a process of scanning a sentence or piece of text for entities that can be further categorized as names, organizations, locations, quantities, monetary values, percentages, etc.

NER API can help organizations better understand customer feedback, analyze trends in large amounts of text data, and extract valuable insights from unstructured text.

A brief history of NER methods

The history of Named Entity Recognition (NER) methods can be traced back to the Message Understanding Conferences (MUC) held in the 1990s in the US. At that time, MUC focused on Information Extraction (IE) research to extract structured information about company activities and defense-related activities from unstructured text sources such as newspaper articles. At that time, the number of entity categories was limited to 7 or 10, and NER taggers for annotating entities in text were created through hand-made dictionaries and rules or some supervised learning techniques.

Over the years, there has been a shift towards supervised learning techniques like Decision Trees and Support Vector Machines, which have become the dominant NER technology. With the advancement in NLP and machine learning, NER has evolved to cover a wider range of entity categories and improved accuracy in recognizing entities in text. Additionally, NER has been integrated into various NLP applications, such as sentiment analysis and text summarization, to extract valuable information from unstructured text data.

Some NER API use cases

You can use NER in numerous fields. Here are some examples of common use cases:

  • Healthcare: extract medical terms, diseases, and symptoms from patient notes and electronic health records, helping to improve patient care and identify potential health risks.
  • Finance: extract financial entities such as stock symbols, company names, and financial events from news articles, social media, and other sources, helping traders and investors make informed decisions.
  • Marketing: extract brand names, product names, and other relevant entities from social media and customer feedback, enabling businesses to gain insights into customer sentiment and identify areas for improvement.
  • Legal: extract legal terms, case citations, and other relevant entities from legal documents, helping lawyers and law firms streamline their document review processes.
  • E-commerce: extract product names, brand names, and other relevant entities from customer reviews and product descriptions, providing valuable insights into customer preferences and helping businesses improve their product offerings.

These are just a few examples of NER APIs uses case. This technology can be leveraged in diverse applications to extract relevant information for further purposes.

Why choose Eden AI to manage your APIs

Companies and developers from a wide range of industries (Social Media, Retail, Health, Finances, Law, etc.) use Eden AI’s unique API to easily integrate NER tasks in their cloud-based applications, without having to build their own solutions.‍

Eden AI offers multiple AI APIs on its platform amongst several technologies: Text-to-Speech, Language Detection, Sentiment Analysis, Summarization, Question Answering, Data Anonymization, Speech Recognition, and so forth.

We want our users to have access to multiple NER engines and manage them in one place so they can reach high performance, optimize cost and cover all their needs. There are many reasons for using multiple APIs:

Fallback provider is the ABCs

You need to set up a provider API that is requested if and only if the main NER API does not perform well (or is down). You can use confidence score returned or other methods to check provider accuracy.

Performance optimization.

After the testing phase, you will be able to build a mapping of providers performance based on the criteria you have chosen (languages, fields, etc.). Each data that you need to process will then be sent to the best NER API.

Cost - Performance ratio optimization.

You can choose the cheapest NER provider that performs well for your data.

Combine multiple AI APIs.

This approach is required if you look for extremely high accuracy. The combination leads to higher costs but allows your AI service to be safe and accurate because NER APIs will validate and invalidate each other for each piece of data.
