Best Named Entity Recognition APIs in 2024

What is Named Entity Recognition?

Named Entity Recognition, also called Entity Categorization or Entity Tagging, typically involves analyzing unstructured text data and categorizing named entities within text, such as people, organizations, locations, dates, and other predefined categories.

The technology uses machine learning and natural language processing (NLP) techniques to recognize patterns, context, and linguistic features, to determine the boundaries and types of named entities. The output can be used for various purposes, such as information extraction, content analysis, search, recommendation systems, and more.

NER APIs use cases

You can use NER in numerous fields, here are some examples of common use cases:

  1. Customer Relationship Management (CRM): automatically identify and extract entities from customer emails, support tickets, or social media interactions.
  2. Content Analysis: identify key entities from web pages, blog posts, or social media content and enable personalized recommendations based on user interests, preferences, or related entities.
  3. Market Research: analyze news articles, social media discussions, or customer reviews and identify mentions of brands, products, competitors, and other relevant entities to gain insights into market trends, sentiment analysis, or competitor analysis.
  4. Legal and Compliance: assist in analyzing legal documents, contracts, or case files to extract names of parties involved, important dates, legal terms, and other pertinent information for document classification, due diligence, or compliance monitoring.
  5. Healthcare and Biomedicine: extract medical entities such as diseases, symptoms, drugs, and treatment methods from clinical notes, research papers, or electronic health records.
  6. Financial Analysis: extract and categorize entities like company names, financial instruments, or market events from news articles, SEC filings, or financial reports. It can support investment decision-making, risk assessment, or portfolio management.

Performance variations of Named Entity Recognition

NER API performance can vary depending on several variables, including the technology used by the provider, the underlying algorithms, the amount of the dataset, the server architecture, and network latency. Listed below are a few typical performance discrepancies between several NER APIs:

  1. Region specialties: some NER APIs improve their machine learning algorithm to make them accurate for text in specific languages spoken in particular countries or regions. For example, some APIs perform well in English (US, UK, Canada, South Africa, Singapore, Hong Kong, Ghana, Ireland, Australia, India, etc.), while others are specialized in Asian languages (Korean, Japanese, Chinese, etc.).
  2. Rare language specialty: some NER providers care about rare languages and dialects. You can find NER APIs that allow you to process text in Gujarati, Marathi, Burmese, Pashto, Zulu, Swahili, etc.
  3. Domain-Specific Jargon: Performance can vary depending on the domain, such as medical, legal, or technical fields. Each domain has its own set of jargon and context which can affect accuracy.
  4. Entity Types and Granularity: The range of entity types (like person, location, organization) and the granularity (subtypes like city, country, or specific types of organizations) can influence how well an NER system performs.

Why choose Eden AI to manage your NER 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 API, 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.
