Keyword Extraction

Keyword Extraction identifies the most important terms or phrases in a document — supporting search indexing, content tagging, summarization, SEO, and analytics. Classical approaches include TF-IDF, RAKE (Rapid Automatic Keyword Extraction), TextRank (a graph-based algorithm inspired by PageRank), and YAKE. Modern approaches use BERT-based extractors (KeyBERT) or LLM prompting ("extract 10 keywords from this article"). Common business applications include SEO content analysis, tagging blog posts and product descriptions, analyzing customer feedback for trending topics, building keyword dashboards for marketing, and routing support tickets based on extracted topics. Tools include MonkeyLearn, AWS Comprehend, Azure AI Language, and the keyword extraction features in major NLP libraries. AI governance, AI compliance, and AI risk management programs use keyword extraction to scan large document repositories for sensitive terms (PII, IP, regulated topics) — supporting responsible AI through scalable content discovery in enterprise AI deployments.
