This paper reports on an evaluation of the keywords produced by Yahoo API context-based term extractor compared to a folksonomy set for the same website. The evaluation process is made in two ways: automatically, by measuring the percentage of overlap between the folksonomy set and Yahoo keywords set; and subjectively, by asking a human indexer to rate the quality of the generated keywords from both systems. The result of the experiment will be considered as an evidence for the rich semantics of folksonomies, thus, they can be used in generating “Semantic Metadata” for annotating web resources stored in del.icio.us.
