Text summarization is the process of distilling the key information from a text while preserving its main ideas and meaning. There are generally two approaches to text summarization:
Extractive Summarization: This method involves selecting important sentences or phrases directly from the original text and combining them to form a summary. Extractive summarization techniques typically use algorithms to rank sentences based on criteria such as relevance, importance, and coherence.
Abstractive Summarization: In contrast to extractive summarization, abstractive summarization involves generating new sentences that convey the main ideas of the original text but may not necessarily exist in the source document. This approach often employs natural language processing (NLP) and machine learning techniques to understand the content of the text and produce concise summaries.
Text summarization finds applications in various fields such as news summarization, document summarization, and summarization of social media posts. It helps users quickly grasp the essential information from large volumes of text, saving time and effort.
