Spam Detection Using Rating and Review Processing Method

Abstract: In recent times, e-commerce sites have become an essential part of people lifestyle. Viewers give feedback and firsthand account of the online products, and these reviews thus play an important role in decision making of the other buyers. So, in order to increase or decrease sales of products, spam reviews are generated by the companies. Hence, there is a need to detect and filter the spam reviews to provide customers genuine reviews of the product. In this paper, a review processing method is proposed. Some parameters have been suggested to find the usefulness of reviews. These parameters show the variation of a particular review from other, thus increasing the probability of it being spam. This method introduced classifies the review as helpful or non-helpful depending on the score assigned to the review.

Staggered Checkpointing and Recovery in Cluster Based Mobile Ad Hoc Networks

Abstract: Checkpointing uses stable storage available in the distributed system for saving the consistent states of processes to which they can rollback at the time of recovery. But the checkpointing techniques for wired and cellular mobile systems are not trivially applicable to ad hoc networks as these networks have limited stable storage and wireless links are of low bandwidth. Moreover if synchronous checkpointing is employed, the processes contend for these limited resources at the time of checkpointing. This paper addresses the application of checkpointing to ad hoc networks and proposes a staggered approach to avoid simultaneous contention for resources. The staggering causes events, which would normally happen at the same time, to start or happen at different times. The proposed protocol does not need FIFO channels and logs minimum number of messages. It supports concurrent checkpoint initiation and successfully handles the overlapping failures in ad hoc networks.

MaDHS: Many-objective discrete harmony search to improve existing package design

Abstract: Recently, many computational intelligence algorithms have been proposed to address software remodularization problem. Unfortunately, it has been observed that the performance of optimizers degrades with the optimization problem containing more than three objectives. In this paper, we propose a many‐objective discrete harmony search (MaDHS) to address the software remodularization problem having more than three objectives. The basic idea of MaDHS is that it uses the quality indicator Iϵ + and external archive to rank and store the nondominated solutions. Along with MaDHS, five remodularization objectives, ie, low coupling, high cohesion, low modification degree, quality of class distribution, and low package instability have also been adapted to improve the package structure of existing object‐oriented software systems. To improve the accuracy of modularization solution, the coupling and cohesion objectives are formulated in terms of various dimensions of direct coupling relationships. To test the supremacy of the proposed approach, it is evaluated over eight real‐world object‐oriented software systems. Simulation results show that the proposed approach outperforms the other existing approaches in terms of couplings, cohesion, modularization quality, modularization merit factor, rate per refactoring of achieved improvement, and external developers view.
