Adaptive Web Crawling Strategies Based on Ontological User Interest Modeling for Personalized Content Retrieval

The exponential growth of web content necessitates efficient and personalized methods for information retrieval. This research introduces an innovative approach to web crawling, centered on adaptive strategies guided by ontological user interest modeling, aiming to enhance the precision of personalized content retrieval. The proposed method employs a dynamic user interest model, constructed, and continually refined through user interactions, leveraging ontology to represent and understand the complex and evolving nature of user interests. In contrast to traditional web crawlers that operate on fixed algorithms, the adaptive crawler anticipates changes in user interests and adjusts its strategies, accordingly, ensuring relevance and timeliness of the retrieved content. The system architecture integrates a multi-faceted profiling mechanism that captures and evolves with user preferences, combined with an intelligent crawling algorithm that prioritizes content based on predicted user interest levels. Empirical results demonstrate a significant improvement in retrieval precision and efficiency, highlighting the crawler's ability to discern and adapt to the nuanced shifts in user interests. Furthermore, the research delves into the implications of such personalized crawling on user privacy and web dynamics, offering insights and recommendations for a balanced approach. This work contributes to the fields of semantic web, personalized content retrieval, and adaptive systems, proposing a novel pathway for the next generation of intelligent web crawlers.
