What is Sentiment Analysis? A Definitive Guide Text Analysis and Sentiment Analysis Solutions

Why should my business use sentiment analysis?

Implementing the long short term memory is a fascinating architecture to process natural language. It starts reading the sentence from the first word to the last word. Later after processing each word, it tries to figure out the sentiment of the sentence. According to Tomas Mikolov, you can also do this by the method called Doc2Vec.

Also, a feature of the same item may receive different sentiments from different users. Users’ sentiments on the features can be regarded as a multi-dimensional rating score, reflecting their preference on the items. However, predicting only the emotion and sentiment does not always convey complete information. The degree or level of emotions and sentiments often plays a crucial role in understanding the exact feeling within a single class (e.g., ‘good’ versus ‘awesome’). Rather than relying on a set of manually created and updated rules, automatic sentiment analysis systems are trained using machine learning techniques. In this case, machine learning refers to algorithms that use deep learning to become more accurate each time they hit a roadblock, require human intervention, or receive user feedback.


All was well, except for the screeching violin they chose as background music. Most marketing departments are already tuned into online mentions as far as volume – they measure more chatter as more brand awareness. But businesses need to look beyond the numbers for deeper insights. Sentiment analysis is a tremendously difficult task even for humans. On average, inter-annotator agreement (a measure of how well two human labelers can make the same annotation decision) is pretty low when it comes to sentiment analysis. And since machines learn from labeled data, sentiment analysis classifiers might not be as precise as other types of classifiers.

Emotions are essential, not only in personal life but in business as well. How your customers and target audience feel about your products or brand provides you with the context necessary to evaluate and improve the product, business, marketing, and communications strategy. Sentiment analysis or opinion mining helps researchers and companies extract insights from user-generated social media and web content. This way, brands can gauge public opinion, conduct detailed market research and review monitoring.

Can it handle many different data sources?

Follow your brand and your competition in real time on social media. Uncover trends just as they emerge, or follow long-term market leanings through analysis of formal market reports and business journals. Sentiment analysis is one of the hardest tasks in natural types of sentiment analysis language processing because even humans struggle to analyze sentiments accurately. So, to help you understand how sentiment analysis could benefit your business, let’s take a look at some examples of texts that you could analyze using sentiment analysis.

Topic-based sentiment analysis finds the sentiment related to a specific topic. This model identifies and extracts topics in the data through keywords and aggregate scoring. A machine learning model can be trained for each of these topics and customized as per the business or industry requirement. For example, topics within healthcare can be the ER, prescription dosage, patient wait-time, etc., while in hospitality, it can be food, reservations, or service. When evaluating online reviews, aspect-based sentiment analysis is most commonly utilized.

Using Thematic For Powerful Sentiment Analysis Insights

It looks at natural language processing, big data, and statistical methodologies. For those who want a really detailed understanding of sentiment analysis there are some great books out there. One of the classics is “Sentiment Analysis and Opinion Mining” by Bing Liu. His book is great at explaining sentiment analysis in a technical yet accessible way.

If you’re looking to understand what your customers think about your brand, that’s a good sign that you might need a sentiment analysis tool. Brandwatch processes 496 million social posts each day, in addition to the more than 1.4 trillion posts in its database. It creates customer insights for you based on sentiments found within all of this social content. It doesn’t consider itself a “sentiment analysis tool” per se, but a data science platform that does text mining in unstructured data to figure out sentiment. ParallelDots is a sentiment analyzer that’s geared towards retail businesses. What’s unique is it comes with image recognition along with text analysis features that are designed to evaluate open-ended responses from customers and pinpoint sentiments within them.

What is the use of sentiment analysis?

In addition, users have a different command of the English language and their grammar or vocabulary might be poor. Users often misspell words, use incorrect sentence constructions, etc., which makes it difficult to use sentiment analysis because of the inconsistency of various users’ language. Traditional social media monitoring often focuses on measuring the number of likes, comments and shares a post gets.

This makes it really easy for stakeholders to understand at a glance what is influencing key business metrics. This allows you to quickly identify the areas of your business where customers are not satisfied. You can then use these insights to types of sentiment analysis drive your business strategy and make improvements. OpenNLP is an Apache toolkit which uses machine learning to process natural language text. It supports tokenization, part-of-speech tagging, named entity extraction, parsing, and much more.

You may need to hire or reassign a team of data engineers and programmers. Deadlines can easily be missed if the team runs into unexpected problems. It’s a custom-built solution so only the tech team that created it will be familiar with how it all works. Luckily there are many online resources to help you as well as automated SaaS sentiment analysis solutions. Or you might choose to build your own solution using open source tools.

This makes it possible to measure the sentiment on processor speed even when people use slightly different words. For example, “slow to load” or “speed issues” which would both contribute to a negative sentiment for the “processor speed” aspect of the laptop. Each class’s collections of words or phrase indicators are defined for to locate desirable patterns on unannotated text. For subjective expression, a different word list has been created. Lists of subjective indicators in words or phrases have been developed by multiple researchers in the linguist and natural language processing field states in Riloff et al..

Tomas Mikolov created a new way to represent words in a vector space. He trains the neural network model on a vast corpus that defines the term “ants” by the hidden layer’s output vector. These word vectors capture the semantic information as it captures enough data to analyze the statistical repartition of the word that follows “ant” in the sentence.

He was invited to be a speaker and judge on international hackathons and conferences like PyData, Google DevFest, and NASA’s international space app challenge. Sentiment analysis is the process of studying people’s opinions and emotions. People are using forums, social networks, blogs, and other platforms to share their opinion, thereby generating a huge amount of data. Meanwhile, users or consumers want to know which product to buy or which movie to watch, so they also read reviews and try to make their decisions accordingly. If sentiments are the things people feel about your company, emotions are the things they feel in general.


The best companies understand the importance of understanding their customers’ sentiments – what they are saying, what they mean and how they are saying. You can use sentiment analysis to identify customer sentiment in comments, reviews, tweets, or social media platforms where people mention your brand. Major brands and businesses often integrate third-party sentiment analysis APIs into their customer support and social media monitoring and management solutions. It helps them analyze the complaints, opinions, and suggestions of customers.

  • Since no emotions are expressed, an analysis system would be unable to tell if this sentence is positive, neutral, or negative.
  • Take the example of a company who has recently launched a new product.
  • Using this tool, you can spot negative social media comments and reply to them on a priority basis.
  • As soon as we introduce a modification, we know which parts of it are greeted with enthusiasm, and which need more work.

There are various ways to calculate a sentiment score, but the most common method is to use a dictionary of negative, neutral, or positive words. The text is then analyzed to see how many negative and positive words it contains. This can give us a good idea of the overall sentiment of the text.
