Detecting opinion spams through supervised boosting approach.

摘要: Product reviews are the individual’s opinions, judgement or belief about a certain product service provided by companies. Such serve as guides for these companies to plan and monitor their business ventures in terms of increasing productivity enhancing product/service qualities. can also increase profits convincing future customers products which they have interest in. In mobile application marketplace such Google Playstore, star ratings used indicators quality. However, among all reviews, hereby known spams exist, disrupt online balance. Previous studies time series neural network approach (which require lot computational power) detect opinion spams. detection performance be restricted accuracy because focusses on basic, discrete document level features only thereby, projecting little statistical relationships. Aiming improve marketplace, this study proposes using based that modelled through supervised boosting Extreme Gradient Boost (XGBoost) Generalized Boosted Regression Model (GBM) evaluate two multilingual datasets (i.e. English Malay language). From evaluation done, it was found XGBoost is most suitable detecting dataset while GBM Gaussian dataset. The comparative analysis indicates implementation proposed had achieved rate 87.43 per cent 86.13
