Natural Language Relies on Grammar and Meaning

Definition

Natural Language

The language humans use to communicate, such as English, Spanish, or Mandarin.

It is complex and ambiguous, making it challenging for computers to understand.
To process natural language, computers need to break it down into smaller components and analyze its structure and meaning.

Note

Key Terms:
- Noun: A word that represents a person, place, thing, or idea (e.g., "dog," "city," "happiness").
- Verb: A word that describes an action or state (e.g., "run," "is," "think").
- Syntax: The rules that govern the structure of sentences (e.g., word order, punctuation).
- Semantics: The meaning of words and sentences.

Key Structures of Natural Language

Parts of speech are categories of words that perform specific functions in a sentence.
1. The main parts of speech include:
  1. Nouns: Represent people, places, things, or ideas.
  2. Verbs: Describe actions or states.
  3. Adjectives: Modify nouns (e.g., "red," "happy").
  4. Adverbs: Modify verbs, adjectives, or other adverbs (e.g., "quickly," "very").
