Why extract keywords?Įxtracting keywords is one of the most important tasks while working with text data in the domain of Text Mining, Information Retrieval and Natural Language Processing. Although they may sound distinct,but they all serve the same purpose: characterization of the topic discussed in a document. “Key phrases”, “ key terms”, “ key segments” or just “ keywords” are the different nomenclatures often used for defining the terms that represent the most relevant information contained in the document. Keyword extraction is nothing but the task of identification of terms that best describe the subject of a document.
