The impact of document structure on keyphrase extraction
Katja Hofmann, Manos Tsagkias, Edgar Meij, Maarten de Rijke · 2009
Keyphrases are short phrases that reflect the main topic of a document. Because manually annotating documents with keyphrases is a time-consuming process, several automatic approaches have been developed. Typically, candidate phrases are extracted using features such as position or frequency in the document text. Document structure may contain useful information about which parts or phrases of a document are important, but has rarely been considered as a source of information for keyphrase extraction.
