Keyword extraction is a process used in natural language processing (NLP) and information retrieval to automatically identify and extract the most important words or phrases (keywords) from a piece of text, such as a document, article, or webpage.
The goal of keyword extraction is to:
1. *Summarize content*: Identify the main topics or themes of the text.
2. *Improve searchability*: Help search engines understand the content and relevance of the text.
3. *Enhance discoverability*: Make it easier for users to find the content when searching for specific keywords.
Keyword extraction techniques can be used in various applications, such as:
1. *Search engine optimization (SEO)*
2. *Content analysis*
3. *Text classification*
4. *Information retrieval*
There are different approaches to keyword extraction, including:
1. *Frequency-based methods*: Identifying words that appear frequently in the text.
2. *Part-of-speech tagging*: Identifying words based on their grammatical category (e.g., nouns, verbs).
3. *Machine learning algorithms*: Using trained models to identify keywords.
