Abstract
Semantic cache diminishes the expectancies of data retrieval over distributed system like cloud-based systems, by reusing already extracted data. It improves the performance of the retrieval system with limited bandwidth which is a key requirement in cloud, fog, edge and other mobile computing technologies. Cache management and query processing over semantic cache are two key activities which should be handled carefully. Query dispensation performs a significant part in terms of reusability in already retrieved data efficiently. Competent query dispensation algorithms made the semantic cache more efficient. This paper identifies four issues that cause decreasing the efficiency of query processing algorithm. The solution is provided to the identified issues to improve the efficiency of query processing. Improvement in efficiency is discussed along each of the issues. Efficiency analysis for enhanced algorithm is also provided and compared with state-of-the-art algorithms in the field. The proposed approach significantly improves the efficiency in many ways.
