This paper introduces FOLCOM, a FOLksonomy Cost estimatiOn Method that uses a story-points-approach to quantitatively assess the efforts that are cumulatively associated with tagging a collection of information objects by a community of users. The method was evaluated through individual, face-to-face structured interviews with eight knowledge management experts from several large ICT enterprises interested in either adopting tagging internally as a knowledge management solution, or just in tangible evidence of its added value. As a second theme of our evaluation, we calibrated the parameters of the method based on data collected from a series of six user experiments, reaching a promising prediction accuracy within a margin of ±25% in 75% of the cases.
