7 Effective NLP Techniques To help Data Science

Natural Language Processing (NLP) techniques are essential tools in data science for analyzing and understanding text data. Key techniques include text tokenization (breaking text into smaller units like words or sentences), sentiment analysis (identifying emotions or opinions), and named entity recognition (NER) (extracting important names, dates, or places). Other methods like text summarization condense large texts into key points, while topic modeling groups similar ideas or themes. Word embeddings transform words into numerical formats for better analysis, and language translation helps analyze multilingual data. These techniques make handling unstructured text data efficient and insightful for decision-making.

  1. What is NLP? NLP (Natural Language Processing) is how computers

    understand and use human language. Why Use NLP in Data Science? It helps analyze text, extract insights, and solve problems using language data. www.ashokveda.com Introduction
  2. Purpose: Clean and prepare text data. Steps: Remove punctuation, lowercase

    text, remove stopwords (e.g., “and,” “the”). www.ashokveda.com Text Preprocessing
  3. What Is It: Break sentences into words or phrases (tokens).

    Why It Helps: Makes text easier to analyze. www.ashokveda.com Tokenization
  4. What Is It: Identify emotions in text (positive, negative, neutral).

    Example: Analyzing customer reviews to find out how they feel about a product. www.ashokveda.com Sentiment Analysis
  5. What Is It: Identify names, places, dates, etc., in text.

    Why It’s Useful: Helps extract key information from unstructured text. www.ashokveda.com Named Entity Recognition (NER)
  6. What Is It: Organize text into categories (e.g., spam or

    not spam). Where It’s Used: Email filtering, topic detection. www.ashokveda.com Text Classification
  7. What Is It: Discover main themes in a collection of

    text. Why It’s Useful: Helps summarize and understand large datasets. www.ashokveda.com Topic Modeling
  8. What Are They: Represent words as numbers (vectors) to capture

    meaning. Popular Methods: Word2Vec, GloVe, BERT. www.ashokveda.com Word Embeddings
