title: Function-based Semantic-ware Cache Replacement Algorithm for Web Systems

abstract: As the web expands overwhelmingly in our daily lives, the pressure to improve the performance of web servers increases. A significant optimization technique that enables scalable web servers to serve clients more efficiently and with lower resource demands consists in caching requested web objects on intermediate cache servers. At the core of the cache server operation is the replacement algorithm, which is responsible for selecting, according to a cache replacement policy, the cached pages that should be removed in order to make space for new pages. Traditional replacement policies used in practice take advantage of temporal reference locality by removing the least recently/frequently requested pages from the cache. Lately, due to the properties of semantic content in of web page, there are some new attempts to implement cache replacement based on multiple parameters including semantic content. This report presents a semantic-aware caching policy enhanced with the use of function-based cache value. Our algorithm is believed to outperform traditional methods in terms of hit rate, which can be useful for website with many small and equal-size web objects.
