The best sentiment analysis tools

Us humans, we’re clever. We read words and know whether they’re giving a positive or negative vibe. We see beyond sarcasm and understand the true sentiment. We get slang. All good, if you’re analyzing a couple of tweets. Listening to your entire audience? You’re gonna need help. Here’s my pick of the best sentiment analysis tools for the job.


Why is sentiment analysis important?

Customer feedback…

understanding/recognize comment's tone

Positive or negative?

Brands use sentiment analysis to find and measure customer opinions and attitudes towards their brand, products, services, campaigns. Analyzing sentiment on social media provides an excellent source of data and will provide digital consumer insights that can:

  • Determine brand reputation
  • Improve customer experience
  • Stop issues becoming a crisis
  • Determine future marketing strategies
  • Improve marketing campaigns and product messaging
  • Identify brand influencers
  • Test business KPIs
  • Generate leads

Cool, no? Social media sentiment analysis will improve your bottom line.

It’s more than tracking numbers. A surge in mentions could be perceived as a good thing. Particularly if you launched a new product, posted a new article, sent out a press release. But, are they positive mentions or negative?

The image above. You see the problem?

Using inaccurate sentiment analysis data can prove catastrophic. Choosing the right tool is essential. A tool that gets sarcasm. That reads the comment from John Doe and understands that he's being sarcastic. He's having a pop. He's being negative. So you have to choose the best. Some social media analysis vendors state that their sentiment analysis algorithm will be, at best, 50-60% accurate.

Until now...

What is sentiment analysis?

Sentiment analysis - opinion mining, text analysis, emotion AI - determines the emotional tone behind words, to understand the attitudes and opinions being expressed. As humans, we do this instinctively - without thinking.

How about content online?

Social media has given consumers a virtual soapbox, from where they can shout their opinions. Good and bad. While humans instantly recognize the sentiment behind a single comment, how should we cope with the explosion of content shared on social media?

Here’s some of what we’re dealing with:

  • 600M+ tweets per day, that’s 6,000 every second
  • 400 hours of video content uploaded to YouTube every minute
  • 500,000+ comments posted on Facebook every minute

We need tools to help. Sentiment analysis tools use natural language processing (NLP) to analyze online conversations and determine deeper context - positive, negative, neutral. These tools mimic our brains, to a greater or lesser extent, allowing us to monitor the sentiment behind online content.

AI-powered sentiment analysis is a hugely popular subject. It’s far too big to dig deep in this post. If you’re interested in reading in more detail, check out - The practical guide to sentiment analysis.
