Text data refers to any form of data represented in textual format, such as articles, emails, social media posts, or customer reviews.
The significance of text data lies in its richness, providing valuable insights into market trends, customer behavior, and even historical events.
Working with text data comes with its own set of hurdles such as inconsistencies, irrelevant information, and noises.
Text preprocessing is a crucial initial step in text data analysis, aimed at transforming raw textual data into a structured format.
Tokenization, Lowercasing, Removing Punctuation, Removing Stop Words, and Stemming and Lemmatization are some of the most common techniques used in text preprocessing.
Vectorization is a fundamental process in natural language processing (NLP) that transforms textual data into numerical vectors, which can be understood and processed by machine learning algorithms.
Bag-of-Words (BoW) and Term Frequency-Inverse Document Frequency (TF-IDF) are some commonly used techniques for vectorization.
N-grams help us capture the relationships and context between words, which can be crucial for tasks like sentiment analysis or topic modeling.
Text preprocessing and transformations shine in various Natural Language Processing (NLP) tasks, including Sentiment Analysis.
Text preprocessing and transformation techniques have emerged as powerful tools, transforming raw text into a format that empowers machine learning models to extract meaning and insights.
