What can you use sentiment analysis for?

Analyze news articles, blogs, forums, and more to gauge brand sentiment, and target certain demographics or regions, as desired. Automatically categorize the urgency of all brand mentions and route them instantly to designated team members. Most marketing departments are already tuned into online mentions as far as volume – they measure more chatter as more brand awareness.

natural language processing sentiment analysis

Maybe you want to track brand sentiment so you can detect disgruntled customers immediately and respond as soon as possible. Maybe you want to compare sentiment from one quarter to the next to see if you need to take action. Then you could dig deeper into your qualitative data to see why sentiment is falling or rising. One of the downsides of using lexicons is that people express emotions in different ways.

Machine Learning (Natural Language Processing – NLP) : Sentiment Analysis II

In this study, it is aimed to indicate accuracy of various machine learning algorithms on Turkish sentiment analysis with using different datasets and preprocessing steps over Twitter data. Moreover, it will contribute with other Turkish studies that already exist and give insights for the next researchers about compatibilities of machine learning algorithms with the sentiment analysis in Turkish language. Kirelli and Arslankaya carried out a study that is Turkish sentiment analysis on global warming topic over random tweets from Twitter with using SVM, K-NN, and Bayesian. The dataset was created with the labelling data based on emoticons; therefore, the accuracy could be little less than that of the manually labeled datasets. However, our study differentiates with using different algorithms and datasets with different topics.

This is often not possible to do manually simply because there is too much data. Specialized SaaS tools have made it easier for businesses to gain deeper insights into their text data. This could include everything from customer reviews to employee surveys and social media posts. The sentiment data from these sources can be used to inform key business decisions. Hybrid sentiment analysis systems combine natural language processing with machine learning to identify weighted sentiment phrases within their larger context. Some types of sentiment analysis overlap with other broad machine learning topics.

Shi, “Study on SVM compared with the other text classification methods,” in Proceedings of the 2nd International Workshop on Education Technology and Computer Science, pp. 219–222, Wuhan, China, March 2010. “dear @verizonsupport your service is straight 💩 in dallas.. been with y’all over a decade and this is all time low for y’all. i’m talking no internet at all.” → Would be tagged as “Negative”. In the example below you can see the overall sentiment across several different channels.


Organizations can determine customer feedback about a service or product by identifying and extracting information in sources like social media. This sentiment analysis can provide significant information about customers’ choices and decision natural language processing sentiment analysis drivers. By combining machine learning, computational linguistics, and computer science, NLP allows a machine to understand natural language including people’s sentiments, evaluations, attitudes, and emotions from written language.

Step Acquire data:

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’). On a daily basis, opinions influence our daily behaviors and are at the core of almost all human activities. One valuable technique tied to these processes is known as natural language processing , which is a field of artificial intelligence that provides the ability to read, understand and derive meaning from human languages. NLP is used in many different types of data analytics processes, including the following.

In the end, if you need to do an analysis detecting subtle differences in meaning, you must look for a tool that employs both machine learning and natural language processing techniques. As seen before, an efficient sentiment analysis system must contain rules for every word combination in its sentiment library. And, after all, strict rules can’t always keep up with the evolution of natural language.

To this end, several machine learning and natural language processing techniques must be combined allowing enterprises to get more accurate results. Sentiment Analysis is a procedure used to determine if a chunk of text is positive, negative or neutral. In text analytics, natural language processing and machine learning techniques are combined to assign sentiment scores to the topics, categories or entities within a phrase.

  • Sentiment analysis has moved beyond merely an interesting, high-tech whim, and will soon become an indispensable tool for all companies of the modern age.
  • There are different algorithms you can implement in sentiment analysis models, depending on how much data you need to analyze, and how accurate you need your model to be.
  • Because evaluation of sentiment analysis is becoming more and more task based, each implementation needs a separate training model to get a more accurate representation of sentiment for a given data set.
  • In the example above words like ‘considerate” and “magnificent” would be classified as positive in sentiment.

As the name suggests, it means to identify the view or emotion behind a situation. Part of Speech taggingis the process of identifying the structural elements of a text document, such as verbs, nouns, adjectives, and adverbs. Both sentences discuss a similar subject, the loss of a baseball game.
