    • Adaptive time-to-live strategies for query result caching in web search engines 

      Alici, S.; Altingovde I.S.; Ozcan, R.; Barla Cambazoglu, B.; Ulusoy O. (2012)
      An important research problem that has recently started to receive attention is the freshness issue in search engine result caches. In the current techniques in literature, the cached search result pages are associated ...
    • Efficient result caching mechanisms in search engines 

      Sazoğlu, Fethi Burak (Bilkent University, 2014)
      The performance of a search engine depends on its components such as crawler, indexer and processor. The query latency, accuracy and recency of the results play crucial role in determining the performance. High performance ...
    • Strategies for setting time-to-live values in result caches 

      Sazoglu, F. B.; Cambazoglu, B. B.; Ozcan, R.; Altingovde, I. S.; Ulusoy, Ö. (2013)
      In web query result caching, staleness of queries are often bounded via a time-to-live (TTL) mechanism, which expires the validity of cached query results at some point in time. In this work, we evaluate the performance ...
    • Timestamp-based result cache invalidation for web search engines 

      Alici, S.; Altingovde I.S.; Ozcan, R.; Cambazoglu, B.B.; Ulusoy O. (2011)
      The result cache is a vital component for efficiency of large-scale web search engines, and maintaining the freshness of cached query results is the current research challenge. As a remedy to this problem, our work proposes ...
