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

      Alıcı, Sadiye; Altıngövde, I. Ş.; Rıfat, Özcan; Cambazoğlu, B. Barla; Ulusoy, Özgür (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 ...
    • Chat mining for gender prediction 

      Küçükyılmaz, Tayfun; Cambazoğlu, B. Barla; Aykanat, Cevdet; Can, Fazlı (Springer, 2006-10)
      The aim of this paper is to investigate the feasibility of predicting the gender of a text document's author using linguistic evidence. For this purpose, term- and style-based classification techniques are evaluated over ...
    • Effect of inverted index partitioning schemes on performance of query processing in parallel text retrieval systems 

      Cambazoğlu, B. Barla; Çatal, A.; Aykanat, Cevdet (Springer, 2006-11)
      Shared-nothing, parallel text retrieval systems require an inverted index, representing a document collection, to be partitioned among a number of processors. In general, the index can be partitioned based on either the ...
    • Hypergraph-theoretic partitioning models for parallel web crawling 

      Türk, Ata; Cambazoğlu, B. Barla; Aykanat, Cevdet (Springer, London, 2012)
      Parallel web crawling is an important technique employed by large-scale search engines for content acquisition. A commonly used inter-processor coordination scheme in parallel crawling systems is the link exchange scheme, ...
    • SE4SEE: A grid-enabled search engine for South-East Europe 

      Cambazoğlu, B. Barla; Turk, Ata; Karaca, Evren; Aykanat, Cevdet; Ucar, Bora; Küçükyılmaz, Tayfun; Temizsoylu O. (2005)
      Search Engine for South-East Europe (SE4SEE) is an application project aiming to develop a grid-enabled search engine that specifically targets the countries in the South-East Europe. It is one of the two selected regional ...
    • A web-site-based partitioning technique for reducing preprocessing overhead of parallel PageRank computation 

      Cevahir, Ali; Aykanat, Cevdet; Turk, Ata; Cambazoğlu, B. Barla (Springer, Berlin, Heidelberg, 2007)
      A power method formulation, which efficiently handles the problem of dangling pages, is investigated for parallelization of PageRank computation. Hypergraph-partitioning-based sparse matrix partitioning methods can be ...
