Performances of Sentiment Analysis vary according to the specificity of data used by each AI engine for their model training. This means that some APIs may perform great for some languages but won’t necessarily for others.

Performance variations according to the languages

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

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

Performance variations according to fields

Some Sentiment Analysis APIs trained their engine with specific data. Some APIs may excel at analyzing sentiment in general texts while others APIs can perform better on reviews or social media post.

Why choose Eden AI to manage your Sentiment Analysis 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 Sentiment Analysis 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, Summarization, Data Anonymization, Speech Recognition, Face Detection, and so forth.

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