Causality, especially when presented in visual form, is especially suited to the task since it is intuitive to understand and to use, and at the same time, it's rich enough to create a semantic network between the representations of real world facts. We give some examples of the suggested system workflow and we present guidelines for its implementation. date: 2011 publication: SSRN Electronic Journal number: 184657 publisher: SSRN pages: 12 id_number: doi:10.2139/ssrn.1846575 institution: IMT Institute for Advanced Studies Lucca official_url: http://dx.doi.org/10.2139/ssrn.1846575 citation: Paolucci, Mario and Picascia, Stefano and Quattrociocchi, Walter Causality in collective filtering.
