NLTK Text Processing Examples

Experiment 4: Basic Text Preprocessing

This section demonstrates fundamental text preprocessing steps using NLTK, including tokenization, stop word removal, filtering for alphabetic tokens, and stemming.

import nltk
from nltk.corpus import stopwords
from nltk.tokenize import word_tokenize
from nltk.stem import PorterStemmer
from nltk.corpus import words

text = "Random sampling is a method of choosing a sample of observations from a population to make assumptions about the population"

tokens = word_tokenize(text)
stop_words = set(stopwords.words('english'))
stemmer = PorterStemmer()

# 1. Lowercase and filter for alphabetic tokens
alpha_tokens = [token.lower() for token in tokens if token.isalpha()]

# 2. Filter

1. Emulsions: Preparation and Stability

Definition: An emulsion is a biphasic liquid dosage form in which one immiscible liquid is dispersed as fine droplets in another liquid with the aid of an emulsifying agent.

Types: Oil-in-water (O/W) and water-in-oil (W/O).

Methods of Preparation

• Dry gum method: Oil, gum, and water are generally used in a 4:2:1 ratio. Gum is triturated with oil, followed by rapid addition of water to form the primary emulsion.
• Wet gum method: Gum is first triturated with water to form mucilage; oil is then added gradually with continuous trituration.
• Bottle method: Suitable mainly for volatile or low-viscosity oils. Ingredients are placed in a bottle and shaken thoroughly.

Identification and Stability
