Imagine having to read every word of every article about your industry you can find. This is probably not feasible, although many of these articles contain valuable information that can benefit your business.  

With named entity recognition, you can scan text for specific keywords that let you know what each article is about, which provides a wealth of information on its own and helps you determine which ones to look closer at.  

Here is an overview of named entity recognition (NER) with a focus on some of the best-named entity recognition APIs to use in your application. 

What is named entity recognition?  

Named entity recognition is a common NLP technique that can help you inspect and make sense of the information you want to understand and work with.  

This method, which is also frequently referred to as entity detection, can quickly scan a document, identify words, and categorize them.  

How does named entity recognition work? 

Named entity recognition uses machine learning to automatically break up the text it is given and sort the terms it contains—called entities—into predetermined categories.  

A NER tool can semantically analyse a piece of text to quickly pull out pull out specific pieces of information information and categorize them to provide information that you can be used to learn more about topics relevant to your company. 

The named entity recognition process typically uses two distinct steps to make sense of information and assign it to a particular category, making it possible to use it according to the user's preferences.  

The named entity recognition process begins by identifying terms within a particular document and then sorting this information into specific categories that allow the user to be more productive. 

What is named entity recognition used for?  

Named entity recognition can help you quickly identify key pieces of information in a wide range of material, such as names of specific people, locations, businesses or other organisations, and other entities that are mentioned in the text.

For example, this can help your business analyse information that may be useful when planning your own marketing strategies.  

It is used in many industries, such as finance, marketing, hospitality, health care and a lot more, to take advantage of their data, especially the unstructured. 

Why is named entity recognition important? 

Named entity recognition can scan and categorize information in a much shorter time than a human would need, helping to determine the specific value that each article, social media post, or other type of text provides in the larger context of your organisation. 

In short, it's a great time and money saver. 

Top-named entity recognition APIs  

Here are some of the top NER APIs offering a variety of features that may be a good fit for your business depending on cost, features, ease of implementation, reliability, and scalability.

Google Cloud NLP joins Google's constantly growing suite of cutting-edge digital products that extend the boundaries of what technology can do for businesses. This natural language AI API prioritises creating content that comes as close to content created by a human as possible, which provides text analysis at a higher level that flows more clearly than what many AI programs are currently capable of providing. 

This API is Google's more complex option, which means it targets larger businesses than its basic AutoML product.  

Pros of Google Cloud NLP 

Google Cloud NLP is a top choice among large international corporations because it provides some of the best multilingual named entity recognition and other AI content that is currently available. This API provides services in 10 different languages, which makes it a significantly more efficient option than finding humans with the language skills to handle the same projects.  

In terms of features, it has text summarization, question answering, text generation, translation, language detection, tokenization, lemmatization, and sentiment analysis capabilities. 

This program also provides several options to choose from, which can help you find a program that best fits your industry. These programs include:  

  • AutoML 
  • Natural Language API 
  • Healthcare Natural Language AI  

Cons of Google Cloud NLP  

Although this API is a strong option in the areas it does provide, Google Cloud NLP is somewhat more limited in the types of information it is currently capable of handling. Many users have found that this API needs significantly more training to be capable of performing fewer tasks than many of the other options on the market.  

Google Cloud NLP is also a more expensive option than many of its competitors, which means it may be more difficult to experiment with than other options. Although this API provides free credits to new customers, the higher cost of this program may not be worthwhile once your business uses these credits and needs to shift to an ongoing subscription. 

2) Microsoft Azure cognitive services

It targets businesses of all sizes and industries that are interested in leveraging AI and machine learning capabilities to enhance their applications. 

Pros of Microsoft Azure 

Microsoft Azure Cognitive is a cost-effective platform that can handle multiple languages, making it useful for diverse applications globally. Developers can leverage this technology along with the Applied AI Services to tailor pre-built AI solutions. Another positive aspect of this tool is its focus on data security. 

Cons of Microsoft Azure 

Despite having a sufficient level of user-friendly, Azure showed a low accuracy rate in testing and had a significant latency period of more than 3200ms. Additionally, it needs to be expertly managed and maintained and requires platform expertise. Ultimately, it received poor ratings from users for its customer support.

AssemblyAI is a versatile entity recognition API option that targets everything from small businesses to major enterprises. It specialises in revenue intelligence and conversation intelligence, areas that have not yet been explored in depth by a large number of similar programs.  

This API goes beyond the basics of recognising relatively simple terms from text. AssemblyAI expands upon this emerging concept by transcribing large amounts of speech, distinguishing between speakers, and creating accurate summaries of the information that a document it is given contains.  

Pros of AssemblyAI 

AssemblyAI provides some of the API industry's leading statistics as far as the overall accuracy of the entities it identifies and categorises, which makes it a top choice among business owners that are interested in pushing the limits of what artificial intelligence tools are currently capable of and using the information AI provides to improve the efficiency and functionality of their businesses.  

This API also prioritises frequently updating the types of information the program is capable of recognising, which makes it a frontrunner when it comes to adding to the overall range of ways businesses can benefit from adding an artificial intelligence API to their digital toolbox. 

AssemblyAI is one of the most accurate speech-to-text API. It is generally better at using proper capitalisation and punctuation than many other AI programs, which means that the information it provides can be closer to the final product and require less extra work from a human to make the text it creates usable.  

Also, you can use this API for free on a limited trial. 

Cons of AssemblyAI 

Although AssemblyAI is a strong platform overall and a good choice for many users, its versatility is somewhat limited because it is only a web-based program.

Frequently asked questions 

Named Entity Recognition (NER) is an NLP technique that identifies and categorizes named entities in a piece of text, such as names of people, organizations, and locations. 

An example of NER is identifying the name of a person, such as "Barack Obama," in a sentence, and categorizing it as a "person" entity type. Another example is identifying the name of a location, such as "New York City," and categorizing it as a "location" entity type. 

The methods of NER include rule-based methods, statistical methods (such as Hidden Markov Models and Conditional Random Fields), and deep learning methods (such as Recurrent Neural Networks and Transformers).
