Summarization definition

Summarization definition refers to the computational process of automatically condensing lengthy documents, articles, or text into concise, coherent summaries that preserve essential information and key insights. This natural language processing task involves extracting or generating shortened versions of source content while maintaining factual accuracy, logical flow, and contextual relevance. Summarization encompasses two primary approaches: extractive summarization, which selects and combines existing sentences from the original text, and abstractive summarization, which generates new text that captures the core meaning using different words and phrases. Modern AI summarization systems leverage transformer models, attention mechanisms, and neural networks to understand document structure, identify salient points, and produce human-like summaries. This capability powers applications in news aggregation, research synthesis, document management, and content curation, enabling users to quickly comprehend large volumes of information. Effective summarization requires balancing brevity with completeness, ensuring critical details are preserved while eliminating redundancy and tangential information.
