Abstract

Keywords are defined as phrases that capture the main topics discussed in a document. As they offer a brief yet precise summary of document content, they can be utilized for various applications. In an IR (information retrieval) environment, they serve as an indication of document relevance for users, as the list of keywords can quickly help to determine whether a given document is relevant to their interest. As keywords reflect a document's main topics, they can be utilized to classify documents into groups by measuring the overlap between the keywords assigned to them. Keywords are also used proactively in information retrieval (i.e., in indexing).
