SENTIMENT ANALYSIS Meaning and
Definition
-
Sentiment analysis, also known as opinion mining, is a computational linguistic technique that involves automatically determining the sentiment or emotional tone expressed in a piece of text, such as a tweet, review, or news article. It utilizes natural language processing (NLP), machine learning, and text analytics to identify and extract subjective information from textual data.
The main goal of sentiment analysis is to classify the sentiment of a given text as positive, negative, or neutral. By analyzing the use of words, phrases, and context, sentiment analysis aims to understand the underlying sentiment, emotions, and opinions conveyed in the text. This analysis may also involve identifying and categorizing specific emotions, including happiness, sadness, anger, or fear.
Sentiment analysis has numerous applications in diverse fields. In marketing, it can help companies monitor and analyze customer feedback and reviews to measure brand reputation and customer satisfaction. In finance, sentiment analysis can be used to predict stock market trends based on public opinions expressed in financial news articles or social media conversations. It is also employed in customer service, social media monitoring, political analysis, and public opinion research, among others.
Trained on a labeled dataset, sentiment analysis algorithms use different techniques, such as machine learning, rule-based systems, or lexicon-based approaches, to classify sentiments. However, due to the complexity and inherent subjectivity of human language, accurately determining sentiment from text remains a challenging task in natural language processing.
