A brief history of Sentiment Analysis methods

The origin of Sentiment Analysis can be traced to the 1950s, when Sentiment Analysis was primarily used on written paper documents.

Sentiment Analysis engines appeared in the early 2000s and became increasingly popular due to the abundance of data from social networks, especially those provided by Twitter.

Today, however, it is widely used to mine subjective information from content on the Internet, including texts, tweets, blogs, social media, news articles, reviews, and comments.

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 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, Question Answering, Data Anonymization, Speech recognition, 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.
