What is natural language processing?

Natural Language Processing (NLP) is a branch of AI that enables computers to understand and interpret text and spoken words, similar to how humans do. In today’s digital landscape, organizations accumulate vast amounts of data from different sources, such as emails, text messages, social media posts, videos, and audio recordings. NLP allows organizations to process and make sense of this data automatically. With NLP, computers can analyze the intent and sentiment behind human communication. From customer service chatbots in retailing to interpreting and summarizing electronic health records in medicine, NLP plays an important role in enhancing user experiences and interactions across industries.

Text Preprocessing in NLP

Natural Language Processing (NLP) has seen tremendous growth and development, becoming an integral part of various applications, from chatbots to sentiment analysis. One of the foundational steps in NLP is text preprocessing, which involves cleaning and preparing raw text data for further analysis or model training. Proper text preprocessing can significantly impact the performance and accuracy of NLP models. Working in natural language processing (NLP) typically involves using computational techniques to analyze and understand human language. This can include tasks such as language understanding, language generation, and language interaction. It includes steps such as Text Input and Data Collection, Text Preprocessing, Text Representation, Feature Extraction, Model Selection and Training, Model Deployment and Inference, Evaluation and Optimization, Iteration and Improvement.

1. Tokenization

Splits the input text into individual words or tokens for downstream processing.

Example: "Hello world" → ["Hello", "world"]

2. Stop Words Removal

Filters out common meaningless words (e.g., and, in, to) to retain semantic content.

Example: "book in room" → ["book", "room"]

3. Stemming

Cuts off word suffixes heuristically to extract root stems.

Example: "running, runner" → "run"

4. Lemmatization

Reduces inflected words to dictionary base form (Lemma).

Example: "better, best" → "good"

5. POS Tagging

Identifies the grammatical role of each word (Noun, Verb, Adjective, etc.).

Example: "Cat runs" → [Cat: NOUN, runs: VERB]

6. Word Frequency

Counts exact occurrences of each word in the text.

Example: "apple banana apple" → {apple: 2, banana: 1}

7. NER Entities

Extracts named entities like persons, locations, and organizations.

Example: "Visit Paris" → [Paris: LOCATION]

8. Chunking

Groups tokens into syntactic phrases like Noun Phrases (NP).

Example: "The red car" → [NP: The red car]

9. Chinking

Removes specific sub-structures from chunked phrases.

Example: Removing adjectives from "red car"

10. Sentence Segmentation

Breaks a paragraph down into individual sentences.

Example: "Hi! How are you?" → 2 sentences

11. N-Grams

Generates continuous sequences of N items (Bigrams, Trigrams).

Example: "Machine learning model" → Bigrams

12. Sentiment Analysis

Determines the emotional tone or polarity (Positive/Negative).

Example: "I love this tool!" → Positive (0.9)

13. Keywords

Extracts the most representative keywords from input text.

Example: AI article → ["AI", "NLP", "Model"]

14. Language Detection

Identifies whether text is Kurdish, Persian, or English.

Example: "سڵاو" → Kurdish (KU)

15. Readability

Calculates text complexity, word averages, and reading time.

Example: Estimated reading time in seconds

16. Normalization

Standardizes orthography (e.g. converting Arabic k/y to standard forms).

Example: "ك" → "ک"

17. Corpus Stats

Measures lexical richness (TTR ratio) and total vocabulary statistics.

Example: TTR = Unique words / Total words

18. Prompt Simulator

Simulates AI prompt engineering structures and response generation.

Example: [Prompt → Simulated LLM Output]
