Abstract:   (2096 Views)
The blogosphere is an effective communication platform where users publish and exchange their opinions. By analyzing user behavior, current and future trends of a community can be discovered. The proposed model for processing the social data of users first extracts related sentiments of weblog comments. An improved PSO algorithm is then employed to detect the trend of users in the TRDT (TRend DeTection) phase. By the discovery of trends at a reasonable time and appropriate precision, this model predicts future trends of the blogosphere using the Q-learning algorithm in the TRPT (TRend PredicTion) phase. Given the ever-increasing processing requirements and a huge volume of data, our approach provides a distributed processing/storage platform for TRDT and TRPT phases. The precision and performance of the proposed model in the TRDT phase are measured by the Chi-squared standard test. Moreover, the evaluation of the TRPT phase shows the comparable precision of the proposed approach with real-world scenarios such as the Netflix predictive system.
