Sentiment Analysis for Better Decision‑Making: Empowering Businesses

Sentiment analysis, often referred to as opinion mining, is a machine-learning technique used to analyze the emotional tone of a text. It functions by extracting subjective information to classify the text sentiment as positive, negative, or neutral. It looks at the attitudes, opinions, and emotions conveyed through the text. Opinion mining looks at positive and negative words to determine sentiment scores and provide insights into the language you use.

Sentiment analysis tools provide valuable insights into how positive and negative words may be perceived by readers. Text analysis can indicate how people interact with certain topics and provide meaningful insights to help businesses better understand public opinion. Deeper insights reflect how customers feel about the text, which can have a huge influence on how they interact with a business in the future.

The main goal of sentiment analysis algorithms is to understand human language and the sentiment behind the text. Sentiment analysis is a technique within natural language processing (NLP), a field of artificial intelligence. NLP is a machine learning technique used to enable computers to comprehend, interpret, and produce human language. Here are the main aspects of NLP:

• Text preprocessing: Preprocessing textual data involves splitting text into words or tokens, removing punctuation, and handling special symbols in an effort to standardize the text for deeper analysis.
• Morphological analysis: Techniques such as stemming and lemmatization take morphological variations such as plural forms or verb tenses into consideration to reduce word variations in the analysis.
• Part-of-speech tagging: Assigning grammatical tags to each word in a sentence to understand the relationships between words (noun, verb, adjective, etc.)
• Syntactic parsing: Analyzing the grammatical structure of a sentence to determine the hierarchical structure and provide insight into syntax.
• Semantic analysis: Understanding textual meaning beyond grammar by identifying the roles of each word in a sentence.
• Sentiment analysis: Determining the emotions expressed in a sentence to help understand opinions and reception of various texts.
• Machine learning and deep learning: Many NLP functions, including sentiment analysis, employ machine learning techniques to streamline the process and label data to make future predictions.

Techniques and methods used in sentiment analysis

There are several methods for implementing a sentiment analysis. Some of the most common sentiment analysis models include rule-based approaches, machine learning algorithms, and hybrid approaches.

Rule-based systems use predefined guidelines and linguistic patterns to identify sentiment. This approach relies on a set of rules manually created by experts. The rules define sentiment-bearing words or phrases in correlation with defined sentiments. Patterns are derived from semantic, contextual, or syntactic implications.

For example, when sentiment analysis tools identify negation words in proximity to sentiment-bearing words, they can easily conclude the flipped polarity of sentiment. Similarly, the use of intensifiers and modifiers such as "extremely" or "barely" impact the intensity of adjacent sentiment-bearing words or phrases. Linguists and experts analyze the performance of the rule-based system to maintain the set of rules and adapt as needed.

On the other hand, the machine learning approach involves training a machine learning system to recognize patterns in the data to determine sentiment. The advantage of implementing machine learning techniques is the automation of sentiment analysis and the ability to analyze complex patterns and relationships.

Unlike rule-based sentiment analysis, experts are not required to define and maintain a set of rules. Rather, this sentiment analysis tool is trained on datasets for increased automation. First, the dataset needs to be created by labeling texts with neutral, negative, or positive sentiments.

The next step involves extracting features such as word frequenting and syntactic dependencies from the data. These two steps train the machine learning model so it can easily recognize patterns in the features.

Another sentiment analysis system is the hybrid approach. Some systems combine several techniques to gather the best possible results. Accurate sentiment analysis is key for utilizing the learnings gained. A hybrid approach may combine a rule-based approach with a machine-learning model to understand more complex patterns.

Sentiment analysis can provide key insights for your business. Understanding how you portray your business can help you improve your brand image and connect on a deeper level with your customers. It's important to perform sentiment analysis regularly to understand the overall sentiment you are portraying and whether this aligns with your brand mission.
