also be found by applying CF-IOF [4] on a training corpus (when available),
in order to perform a classication that is more relevant to the data under
analysis. After seed concepts are identied, the module spreads their values
across the IsaCore graph. This operation, an approximation of many steps
of spreading activation, transfers the most activation to concepts that are
connected to the seed concepts by short paths or many different paths in
affective common-sense knowledge. Therefore, the concepts of each SBoC
provided by the sentic parser are projected on the matrix resulting from
spectral association in order to calculate their semantic relatedness to each
seed concept and, hence, their degree of belong ...
