Best Topic/Entity Extraction APIs in 2024

What is Topic Extraction?

Topic Extraction API, also known as Entity Extraction or Taxonomy of content, uses natural language processing (NLP) techniques to identify the main ideas and concepts in the text and group them into meaningful topics.

The technology typically takes in a piece of text as input and returns a list of topics along with their associated keywords or phrases. It can be used to analyze various types of text data, including articles, social media posts, customer reviews, and more. Topic Extraction API can be useful in a variety of applications, such as content categorization, sentiment analysis, trend analysis, and search engine optimization.

It’s worth noting that Topic Extraction API can be used instantly, unlike Custom Text Classification which requires a dataset beforehand.

Topic Extraction APIs uses cases

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

  • Academic Research: analyze large volumes of text data and identify key themes and topics. This information can be used to inform research questions, identify knowledge gaps, and conduct literature reviews.
  • Business: analyze customer reviews, feedback, and comments to identify customer needs, preferences, and sentiments. This information can be used to improve products and services, enhance customer satisfaction, and increase customer retention.
  • Healthcare: extract relevant information from medical records, such as symptoms, diagnoses, and treatments. This information can be used to identify patterns and trends in patient health outcomes, inform clinical decision-making, and improve patient care.
  • News and Media: categorize automatically news articles based on their content and topics, making it easier to manage and search for relevant news stories. It can also help to identify trending topics and news events in real time.
  • Law Enforcement: analyze data on various platforms and sources to detect criminal activities, track suspects, and identify potential threats.
  • E-commerce: analyze product descriptions, reviews, and feedback to identify popular products, customer preferences, and trends. This information can be used to optimize product listings, improve customer satisfaction, and increase sales.
  • Social Media Analysis: identify trending topics, monitor brand reputation, and detect customer sentiment. This information can be used to improve social media engagement strategies.

These are just a few examples of Topic Extraction APIs uses case. This technology can be used in various fields to extract meaningful insights from unstructured text data.

Performance variations of Topic Extraction APIs

For all companies who use Topic Extraction in their software: cost and performance are real concerns. The Topic Extraction market is quite dense and all those providers have their benefits and weaknesses.

Performances of Topic Extraction APIs vary according to the specificity of data used by each AI engine for their model training

Performance variations across languages

Topic Extraction APIs perform differently depending on the language of the text and some providers are specialized in specific languages. Different specificities exist

  • Region specialties: some Topic Extraction 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.).
  • Rare language specialty: some Topic Extraction providers care about rare languages and dialects. You can find Topic Extraction APIs that allow you to process text in Gujarati, Marathi, Burmese, Pashto, Zulu, Swahili, etc.

Performance variations according to fields

Some Topic Extraction APIs trained their engine with specific data. This means their performance can vary depending on several factors, such as the length and complexity of the text, and the type of content being analyzed. For example, some Topic Extraction APIs may perform best in identifying key topics in structured news articles, while others may be better suited to analyzing informal and diverse topics found in forum discussions or social media post.

Why choose Eden AI to manage your Topic Extraction 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 Topic Extraction 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, Logo Detection, Question Answering, Data Anonymization, Speech Recognition, and so forth.

We want our users to have access to multiple Topic Extraction 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 Topic Extraction 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 Topic Extraction API.
  • Cost - Performance ratio optimization: You can choose the cheapest Topic Extraction API 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 Topic Extraction APIs will validate and invalidate each other for each piece of data.
