Top 10 Best Tools, Libraries and Packages for Sentiment Analysis to Measure Brand Sentiment in 2020

How often do we receive a text from our friends and family and often get caught up or confused about what they intend to mean, if they are joking or being serious! As humans, we really don’t put up quite well over the tone and emotions behind text messages and this ultimately leads to not fully understanding the intent behind a message, making characters like sarcasm or wittiness hard to process! 

With the approach of online technology including social media, it was getting harder to determine the intent behind a message as there was no definite way to recognize the sentiment behind human interactions over text messages. Due to this underlying problem, it became a matter of concern for businesses as there was no proper way to decipher the sentiment behind customer reviews and to interpret whether there is a positive or negative correlation between the product/services and the customer experience. Considering the limitations such as word limit and distorted feedback, the customer service team lacked the information required in order to approach the query.

With the forthcoming of text-oriented communications like social media, there had to be an efficient way which could allow businesses to accurately analyse their brand sentiment and also the feedback from their customers. This paved a way for the use of a sentiment analysis tool which can effectively measure the sentiment behind text and also analyze the tone behind customer reviews and feedback from all over the internet. 

With that being said, let’s dive into what a sentiment analysis tool is and then move forward to our top 10 best tools for sentiment analysis in 2020.

Why use a Sentiment Analysis Tool?

To be precise, a sentiment analysis tool interprets text conversion, processes the tone behind the content and displays the accurate intent behind a message!  It thus takes the construct from user reviews and analyses the feedback into a measurable format on the basis of the language, tone and intent behind it. 

Brands use this information to evaluate the key areas of improvement and also engage with customer queries efficiently using all online mediums.

Sentiment Analysis for Brands

By using an automated framework to evaluate text-based communications, companies are able to discover how consumers actually feel about their goods, services and marketing strategies. 

By investing the time into a sentiment analysis software or tool, it not only gives the correct insight into understanding the ideal customer, but also saves a lot of valuable time for our team members. 

Instead of going through every customer feedback and responding one at a time, a sentiment analysis tool quickly analyses the input and interprets the data in the form of a neutral, positive or negative sentiment score and displays the analytics from analyzing these results in a visual format in the form of graphs and charts to better understand the trend over time in customer feedback. 

Having a basic perspective about how a sentiment analysis tool works and how it’s optimum for brands, let’s dive straight into our top 10 best sentiment analysis tools, libraries and packages in 2020.

Such scores are defined by how much a given sentence occurs in the vicinity of a collection of recognized positive terms (eg, nice, fantastic, spectacular) and a collection of poor words (eg, terrible, horrific, awful).
