Research on Online Publicity Effect Evaluation of Significant Subject

As the problem of that traditional evaluation system is difficult to reflect the media effect in the process of information dissemination, this paper proposed a scheme to evaluate the significant subjects' online publicity. The scheme used the combination weighting to build an indicator system. Six parallel indexes are chosen as the evaluation criterion. The ranking result is obtained after the analysis of exemplary cases. The iterative ratio is revised based on Mc Quail 's information processing theory and "Final ranking corresponds to six First level index". The final score corresponds to the description of publicity effect in communication effect theory.
