- Abstract: Online reviews are potent sources for industry owners and buyers, however
opportunistic people may try to destruct or promote their desired product by
publishing fake comments named spam opinion. So far, many models have been
developed to detect spam opinions, but none have addressed the issue of spam
attack. It is a way a smart spammer can deceive the system in a manner in which
he can continue generating spams without the fear of being detected and blocked
by the system. In this paper, the spam attacks are discussed. Moreover, a
robust graph-based spam detection method is proposed. The method respectively
estimates honesty, trust and reliability values of reviews, reviewers, and
products considering possible deception scenarios. The paper also presents the
efficiency of the proposed method as compared to other graph-based methods
through some case studies.

Backdoor attacks aim to surreptitiously insert malicious triggers into DNN models, granting unauthorized control during testing scenarios.
Existing methods lack robustness against defense strategies and predominantly focus on enhancing trigger stealthiness while randomly selecting poisoned samples.
We introduce a straightforward yet highly effective sampling methodology that leverages confidence scores. Specifically, it selects samples with lower confidence scores, significantly increasing the challenge for defenders in identifying and countering these attacks.

We introduce the novel approach towards fake text reviews detection in collaborative filtering recommender systems.
The existing algorithms concentrate on detecting the fake reviews, generated by language models and ignore the texts, written by dishonest users.
We propose the contrastive learning-based architecture, which utilizes the user demographic characteristics, along with the text reviews, as the additional evidence against fakes.

In many online sites, there are options for posting reviews, and thus creating scopes for fake paid reviews or untruthful reviews.
These concocted reviews can mislead the general public and put them in a perplexity whether to believe the review or not.
Prominent machine learning techniques have been introduced to solve the problem of spam review detection.

Malicious reviewers strategically bid in order to unethically manipulate the paper assignment.
A critical impediment towards creating and evaluating methods to mitigate this issue is the lack of publicly-available data on malicious paper bidding.
We release a novel dataset, collected from a mock conference activity where participants were instructed to bid either honestly or maliciously.
