    • Cluster searching strategies for collaborative recommendation systems 

      Altingovde, I. S.; Subakan, Ö. N.; Ulusoy, Özgür (2013)
      In-memory nearest neighbor computation is a typical collaborative filtering approach for high recommendation accuracy. However, this approach is not scalable given the huge number of customers and items in typical commercial ...

    • Exploiting query views for static index pruning in web search engines 

      Altıngövde, İsmail Şengör; Özcan, Rıfat; Ulusoy, Özgür (ACM, 2009-11)
      We propose incorporating query views in a number of static pruning strategies, namely term-centric, document-centric and access-based approaches. These query-view based strategies considerably outperform their counterparts ...

    • Memory resident parallel inverted index construction 

      Küçükyılmaz, Tayfun; Türk, Ata; Aykanat, Cevdet (Springer, London, 2012)
      Advances in cloud computing, 64-bit architectures and huge RAMs enable performing many search related tasks in memory.We argue that term-based partitioned parallel inverted index construction is among such tasks, and provide ...

    • SONIC: streaming overlapping community detection 

      Sarıyüce, A. E.; Gedik, B.; Jacques-Silva, G.; Wu, Kun-Lung; Catalyurek, U.V. (Springer, 2016)
      A community within a graph can be broadly defined as a set of vertices that exhibit high cohesiveness (relatively high number of edges within the set) and low conductance (relatively low number of edges leaving the set). ...
