Abstract: In this research, we are trying to investigate the behavior of fake accounts on Yelp data set to generate fake negative/positive reviews for competitors or itself and identify the fake reviews based on several « review-centric » and « reviewer-centric » features, which contribute the most fake reviews in entire data set. It has been observed that the existing machine learning methods fail to classify the fake reviews and provide the low classification results. Therefore, we are trying to propose a deep learning-based fake review detection framework (FRDF) that detects fake reviews after extracting some unique and novel features from the data set and employ their collective behavior in a unified manner.

Bias in Artificial Intelligence

Abstract: Applying AI to business application gives us the capacity to automate repetitive tasks as well as to increase business revenues by adapting to users’ needs, profiles and behaviors. However, machine learning data, algorithms, and other design choices that shape AI systems may reflect and amplify existing cultural bias and prejudices. Consequently, when we develop data-driven AI products and feed them data, we should be careful that we are neither simply confirming existing biases nor introducing new ones. This research will help advancing the state-of-art from heuristic repairing, to proactive and theoretically supported prevention tackling the bias problematic from both an algorithmic and a design perspectives
