Keywords can be considered as a set of words which are important and subject correlated cohesively in a document. Therefore, an automatic keyword extraction method based on density clustering is proposed in this paper. Web pages are segmented, and the words are clustered based on their co-occurrence. Co-occurrence relations between words are analyzed, and keywords that capture the main topics of the document are extracted.
