To understand consumer behavior in the business world, proper analysis is needed to measure it, one of which is sentiment analysis. This analysis is used in various contexts, including business, social media, market research, and others.
In financial market analysis, for example, investors can use sentiment analysis to understand how the market responds to certain news or events that can affect the price of stocks or other assets.
On the other hand, sentiment analysis also has a significant impact on the crypto asset market. For example, positive or negative news circulating on social media, the news, or other online platforms can dramatically affect the price of cryptocurrencies.
Positive sentiment can push prices up, while negative sentiment can cause a sharp decline.
So, to better understand what sentiment analysis is, its types, how it works, and the relationship between sentiment and the crypto market, see the following review.
What is Sentiment Analysis?
Basically, sentiment analysis is the process of identifying, measuring, and understanding the views, emotions, or opinions contained in text or other non-numeric data.
In another sense, sentiment analysis is the process of identifying, classifying, and evaluating opinions, feelings, or sentiments contained in texts, such as product reviews, social media comments, or news articles.
Meanwhile, the main purpose of sentiment analysis is to extract information about how people feel about a particular subject, product, service, or event.
This analysis uses natural language processing (NLP) techniques and machine learning to recognize and classify text into different categories, such as positive, negative, or neutral.
Why is Sentiment Analysis Important?
Sentiment analysis plays an important role in a variety of contexts, including the general world and crypto markets. Basically, sentiment analysis will help in understanding the opinions, views, and emotions expressed by the public. In an era when information spreads quickly through social media and online platforms, understanding how people respond to news, events, or products is, of course, very valuable.
On the other hand, for companies and brands, sentiment analysis helps monitor their image in the eyes of the public. This allows them to respond quickly to changing public views and emotions and address issues that may affect their reputation.
Furthermore, sentiment analysis also helps companies understand how customers feel about their products or services. This will assist in designing a more targeted marketing strategy and identifying needs or problems that need to be addressed.
As for the financial world, including the crypto market, sentiment analysis can provide investors with important insights into how the market responds to certain news, trends, and events. This can help them make better investment decisions.
In the crypto world, sentiment analysis has significant implications. For example, news, rumors, or opinions spread on social media and crypto platforms can affect price movements dramatically. Positive sentiment can trigger price spikes, while negative sentiment can cause sharp declines.
In addition, through sentiment analysis, traders and investors can identify emerging market trends. For example, if positive sentiments constantly emerge about a certain crypto project, it can be an indicator that the project is getting a lot of attention and support.
Types of Sentiment Analysis
Please note that sentiment analysis consists of various types. An understanding of these different types of sentiment analysis will be key to extracting deeper insights from text data and non-numeric information.
In the end, you can also choose the type of sentiment analysis that best suits your business needs. The following are several types of sentiment analysis that are important to understand:
1. Fine Grained
The first type of sentiment analysis is fine grained. This type of analysis has a specific assessment and will help users get a wider range of assessments.
In general, fine grained is used more often in e-commerce reviews. For those who value polarity precision, this analysis is a great choice because it can include different positive and negative levels.
An example of fine grained sentiment analysis is a rating system with stars. For example, five stars are for a very positive response, while one star is for a very negative response.
2. Intent Based
The next type is intent based. This one sentiment analysis will help to find out the intent of customer opinions based on a text. This type of sentiment analysis can dig deeper into the customer’s intentions in writing, whether they include criticism, complaints, suggestions, opinions, or appreciation of the product.
Take, for example, when a customer mentions the word “gile” in the context of the sentence, “Gile, it’s delicious!”, Using this type of intent-based sentiment analysis, it can be understood that the meaning of the word “gile” mentioned by the customer earlier is a positive word, even though the word ” gile” may have a negative meaning.
3. Aspect Based
Finally, there is an aspect-based analysis type. This type of sentiment analysis is used to find out about aspects that have neutral, negative, or positive ratings from customers. By using this one sentiment analysis, users can understand sentences that describe positive or negative responses to the product.
How Does Sentiment Analysis Work?
After knowing the meaning and types, now is the time to understand how sentiment analysis works. Understanding how sentiment analysis works has several important benefits. Primarily in the context of natural language processing and data analysis. In collecting data, the way sentiment analysis works is divided into three steps, namely as follows:
The first step is classification. In this case, the machine will classify the data as an opinion from a text. In the sentiment analysis method, there are 3 classifications that can be made, including:
Machine learning: A number of features available here can recognize a person’s sentiment or point of view in a text. This one method is now becoming increasingly popular because it is considered representative.
Lexicon-based: This method uses a number of words that are considered with a polarity score in order to find out the user’s response to a topic. The advantage is that it does not require training data, while the weakness lies in the number of words that are not included in the lexicon
The next step is evaluation. This step uses an evaluation matrix, including recall, precision, accuracy, and an F-score. This step also involves measuring averages, for example, macro, micro, and weighted F1 scores, when handling data that falls into 2 or more classifications. Meanwhile, the metrics used are based on the balance of the classification of data sets.
3. Data Visualization
Finally, the step taken is data visualization, namely by using a chart according to the needs of the company or anyone who uses the data. As usual, most people will use techniques that are already popular, for example, histograms, matrices, or graphs.
However, the end result of this sentiment analysis will vary widely. In addition, the available data can be accompanied by other domains involved. Therefore, data visualization techniques such as interactive maps, sparkline styles, and word clouds are quite effective in displaying analysis results.
The Relationship Between Sentiments and Crypto Markets
It should also be noted that the relationship between public sentiment and the crypto asset market is very close because the crypto market is heavily influenced by the collective perceptions and emotions of market participants. Positive or negative sentiments that develop in society and are expressed through news, social media, and other online platforms can trigger price changes and market trends.
Generally, positive sentiment is followed by an increase in crypto prices as investors tend to be more inclined to buy assets. On the other hand, negative sentiment can trigger mass sales and price reductions. Market trends such as bull markets and bear markets are also often closely related to the dominant sentiment in the market.
On the other hand, volatile sentiment can result in high volatility in crypto asset prices. Given that the crypto market is relatively new and not very stable, changes in sentiment can have a big impact on prices in a short period of time.
Furthermore, when positive or negative sentiment appears in one place, for example, in big news, it can trigger a chain reaction on other online platforms.
For an example of how news announcements and events impact sentiment and prices of crypto assets, suppose there is news that a crypto project has announced that they will be integrating with a well-known e-commerce platform for payments.
In this regard, the positive sentiment is that investors and the crypto community responded enthusiastically and saw the integration as a big step in adopting crypto in everyday life.
Meanwhile, the impact on the price is that the price of the crypto will increase sharply within hours of the announcement due to high buying demand.
In conclusion, sentiment analysis plays a very important role in the crypto world. In an environment where news, opinion, and emotion travel so quickly, understanding fundamental market sentiment can provide valuable insight into price movements, trends, and reactions to events and announcements.
In this case, positive sentiments can lead to price increases and investor participation, while negative sentiments can lead to falling prices and uncertainty in the crypto market.
In addition, the use of sentiment analysis helps market participants respond quickly to changes in sentiment and understand how public views can affect market dynamics. This will help investors and traders make more informed decisions, as well as identify potential opportunities and risks.
However, keep in mind that sentiment analysis is not a guarantee of success or a perfect method. This is because market sentiment can change quickly and is influenced by various factors, including speculation, market manipulation, and unforeseen external issues. Therefore, while sentiment analysis provides valuable insights, sound decision-making must still be supported by sound fundamental and technical analysis.
