ABSTRACT:
A hot topic extraction apparatus for extracting a hot topic from information includes an information collection unit, an information storage unit, and a hot topic extraction unit. The information collection unit collects a document from an information source. The information storage unit stores collected information. The hot topic extraction unit extracts a document from the information storage unit while the information collection unit collects the document, and retrieves a document from the retrieved document, thereby extracting a hot topic from information contained in various information sources, not extracting a hot topic from a given document.
