The Ultimate List of Sentiment Analysis Tools for 2020

Today, almost all online communications happen via text. Emails, live chats, social media comments, tweets, the list is endless. It’s impossible for human agents to cope with all the information that is produced on a daily basis (2.5 quintillion bytes of data is created every day!). Instead, companies need to implement tools that can help filter and interpret all the texts they receive. 

Discovering how customers feel toward a product or service is essential today, but analyzing this data by hand is inefficient and boring. Luckily, sentiment analysis tools are here to help. This software uses Natural Language Processing (NLP) to examine pieces of text and automatically evaluate the overall feeling behind your customers’ messages, classifying them into positive, negative, or neutral. 

You can build your own sentiment analysis from scratch using open source libraries, but this process is quite demanding in terms of time and resources. Plus, you’ll need to have a deep understanding of coding and machine learning to build an effective and reliable sentiment analysis model. 

Sentiment analysis tools come in handy if you want to avoid the hassle of building a model from scratch. They are ready to use, so you won’t need to set up any infrastructure. Also, some sentiment analysis tools can be easily integrated with other everyday apps like Excel, Google Sheets, or Zapier

Now that you understand what a sentiment analysis tool is and some of their benefits, let’s take a look at the top eight tools for sentiment analysis in 2019.

Additionally, you can define a dictionary to include any specific vocabulary that you might use in your field.

5. Rosette | API for Sentiment Analysis in 30 Languages

Working with Rosette is a breeze. This is an API that uses AI to analyze natural language. It was first used to perform sentiment analysis on social media, but eventually branched out to analyze entire documents and individual entities mentioned in the text, for example, the sentiment expressed by customers when they mention a specific product, company, or person. Rosette is able to identify parts of speech by means of morphological analysis and lemmatization (the grouping of inflected word forms so they are not analyzed separately).

If you’re an international company you can train Rosette’s sentiment analysis tool to identify up to 30 languages. 

Pricing: Variable.

6. Repustate | Customizable API for Sentiment Analysis

Repustate even offers a free trial so you can try the tool to see if it really suits your needs.
