The recommendation system provides the user with their needed item or service by analyzing their preference history. In recent times the location-based recommendation has played a significant role in our everyday life. User interaction towards the internet is based on the social relationships comprising User Generated Content (UGC) like online reviews. A collaborative filtering approach is a popular recommendation framework for making recommendations to a new user based on comparable user content. However, it is vulnerable to Shilling attacks, in which shills put any unethical data into the ratings or comments database in order to modify the recommendations. As a lacking of trust format, the risk of misinformation becomes a research and evaluation concern. This paper proposes a trustworthy recommendation framework using the content features of the Deceptive opinion spam corpus dataset by employing the various deep learning algorithms in predicting the truthfulness of the reviews. Among the inspired models, the proposed hybrid combination of CNN-LSTM involving content feature excels in accuracy and prediction, thereby improving the performance and stability of the recommendation system.
