Abstract |
|
With the increase in the customer reviews, feedbacks, suggestions posted in the web forum, blogs led to the emergence
of spam. Spam detection is important for both the customer and service providers to arrive at a proper decision while purchasing
as well as marketing the product. Most of the research works has been developed only for sentiment classification for the past few
decades which favors the spammers to write fake reviews. Hence it is important to detect the spam reviews but the major issues in
spam review detection are the high dimensionality of feature space which contains redundant, noisy and irrelevant features. To resolve
this, optimization method for selecting subset of features is necessary. Hence, this paper proposes Hybridization of Improved Binary
Particle Swarm Optimization (iBPSO) and Binary Flower Pollination Algorithm (BFPA) utilized with Naive Bayes and k-NN for
optimization process to improve the classification performance. Experimentation result proves that hybrid iBPSO BFPA outperformed
the existing approach by obtaining the maximum accuracy of 94.43% for review spam dataset when compared with existing Cuckoo
Search NB(CS) and Shuffled Frog Leaping Algorithm NB (SFLA) which achieved only 81.87% and 88.23%. The experimental result
proves that the proposed hybrid method increases the classification accuracy |
