Purpose: The user interest in content searching in the web will be changed over by time. Design/methodology/approach: The system is in need to find the content of user over the temporal aspects. Findings: So, predicting the user interest over the time by analyzing the fluctuations of their search keyword is important. Research limitations/implications: So, predicting the user interest over the time by analyzing the fluctuations of their search keyword is important. Practical implications: In this work, fuzzy neural network techniques are used to predict the user interest fluctuation in different times in different scenarios. Social implications: In this proposed work, both the long-term and short-term interest are evaluated using the specialized user interface designed to retrieve the user interest based on the user searching activities. Originality/value: This work also categorizes the future needs of users using this proposed system. © 2020, Emerald Publishing Limited.
