We can definitely tell that with the development of e-commerce, SaaS tools and digital technologies, sentiment analysis is becoming the thing.

What is Sentiment Analysis?

There’s a couple of definitions, be it by Wikipedia, by Brandwatch, or by Lexalytics. All in all, sentiment analysis boils down to one thing:

It’s the process of analyzing online pieces of writing to determine the emotional tone they carry.

In simple words, sentiment analysis is used to find the author’s attitude towards something. Some tools categorize pieces of writing as positive, neutral, or negative.

Here’s an example of a negative piece of writing because it contains hate.

Who Uses Sentiment Analysis?

Sentiment analysis and opinion mining have many applications ranging from ecommerce, marketing, to politics and any other research.

Let’s see how these areas make use of sentiment analysis.

Ecommerce and marketing

Reputation management

Sentiment analysis can be used in reputation management — to analyze web and social media mentions about a product, a service, a marketing campaign or a brand.

This is how companies can discover consumer attitudes towards them, their products, services, or marketing campaigns on discussion forums, review sites, Twitter, Instagram, Facebook and other publicly available sources.

Customer feedback

Companies also do sentiment analysis to collect and analyze customer feedback.

These days, consumers use social media to share both their positive and negative experiences with brands. Sentiment analysis tools can detect both mentions conveying super positive pieces of content showing strengths of a product, or a service and negative mentions, bad reviews, or technical problems users write about online.

Crises prevention

Some sentiment analysis tools like Brand24 collect and analyze pieces of writing including predefined keywords in real time. On seeing a negative mention, a company can quickly react and nip the problem in the bud before it escalates into a social media crisis.

United Airlines

Last year, United Airlines experienced an image crisis. Using a social media monitoring tool, we analyzed the sentiment of #UnitedAirlines hashtag. I wonder if they used a sentiment analysis tool at that time.

Here’s what popped out:

UBER

Some time ago UBER used social media monitoring and sentiment analysis tool to discover if users like the new version of their app.

It’s a pretty good case study that illustrates the use of sentiment analysis.

“At Uber, we use social listening on a daily basis, which allows us to understand how our users feel about the changes we’re implementing. As soon as we introduce a modification, we know which parts of it are greeted with enthusiasm, and which need more work. We’re happy that the new app was received so well because we’ve put a lot of work into it.”

Politics

Sentiment analysis is also used in politics. In 2012, the Obama administration used sentiment analysis tools to analyze the reception of policy announcement during 2012 presidential election.

During the last presidential election in the US, some organizations analyzed, for example how many negative mentions about particular candidates appeared in the media and news reports.

There have been at least a few academic papers examining sentiment analysis in relation to politics.

  • Prediction of Indian election on the basis of Twitter sentiment analysis
  • Political Data Science: Analyzing Trump, Clinton and Sanders Tweets and Sentiment
  • Analysis of political sentiment in presidential elections in Egypt using Twitter data

Research

Sentiment analysis and opinion mining finds application in any form of research and can extract sentiment from any piece of writing on the Web.

How sentiment analysis is done?

The science behind sentiment analysis is based on algorithms using natural language processing to to categorize pieces of writing as positive, neutral, or negative.

The algorithm is designed to identify positive and negative words, such as “fantastic”, “beautiful”, “disappointing”, “terrible”, etc.

This, however, isn’t always that easy.

Sentiment analysis challenges

Due to language complexity, sentiment analysis has to face at least a couple of issues.

Contrastive conjunction

One problem a sentiment analysis tool has to face is contrastive conjunctions — they happen when one piece of writing (a sentence) consists of two contradictory words (both positive and negative).

  • Example sentence: “The weather was terrible, but the hike was amazing!”

Named-entity recognition

Another big problem sentiment analysis algorithms face is named-entity recognition. Words in context have different meaning.

  • Does “Everest” refer to the mountain or to the movie?

Anaphora resolution

Also known as pronoun resolution, describes the problem of references within a sentence: what a pronoun, or a noun refers to.

  • Example sentence: “We went to the theater and went for a dinner. It was awful.”

Sarcasm

Is there any sentiment analysis tool detecting sarcasm? Please recommend one!

  • Example sentence: “I’m so happy the plane is delayed.”

The Internet

It just so happens that any language used online takes its own form. The economy of language and the Internet as a medium result in poor spelling, abbreviations, acronyms, lack of capitals and poor grammar. Analyzing such pieces of writing may cause problems for sentiment analysis algorithms.

How to do sentiment analysis?

Now let’s say what’s the best way to do sentiment analysis.

There’s a couple of sentiment analysis tools on the market. What’s interesting, most of social media monitoring tools can perform such an analysis.
