Satisfaction meter

Definition:


Sentiment analysis (or opinion mining) is a natural language processing technique used to determine whether data is positive, negative or neutral. Sentiment analysis is often performed on textual data to help businesses monitor brand and product sentiment in customer feedback, and understand customer needs.


History:


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

Use cases:


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

  • Healthcare: analyze satisfaction surveys to identify negative points and improve hospitals
  • Banking: analyze text from social media campaigns to make sure that its customers did not turn to other banks.
  • Call centers: identify negative interactions in calls, to analyze it with other NLP techniques
  • Retail: analyze after-sales service requests to identify those which must be treated


The Multi cloud approach


When you need a Sentiment Analysis engine, you have 2 options:

  • First option: multiple open source Sentiment Analysis engines exist, they are free to use. Some of them can be performant but it can be complex to set up and use. Using an open source AI library requires data science expertise. Moreover, you will need to set up a server internally to run open source engines.
  • Second option: you can use engines from your cloud provider. Actually, cloud providers like Google Cloud, AWS, Microsoft Azure, Alibaba Cloud or IBM Watson are all providing multiple AI engines including Sentiment Analysis. This option looks very easy because you can stay in a known environment where you might have abilities in your company and the engine is ready-to-use.

The only way you have to select the right provider is to benchmark different providers’ engines with your data and choose the best OR combine different providers’ engines results. You can also compare prices if the price is one of your priorities, as well as you can do for rapidity.

This method is the best in terms of performance and optimization but it presents many inconveniences:

  • you may not know every performant providers on the market
  • you need to subscribe and contract with all providers
  • you need to master each providers API documentation
  • you need to check their pricings
  • You need to process data in each engine to realize the benchmark

Here is where Eden AI becomes very useful. You just have to subscribe and create an Eden AI account, and you have access to many providers engines for many technologies including Sentiment Analysis. The platform allows you to benchmark and visualize results from different engines, and also allows you to have centralized cost for the use of different providers.
