    • Application of map/reduce paradigm in supercomputing systems 

      Demirci, Gündüz Vehbi (Bilkent University, 2013)
      Map/Reduce is a framework first introduced by Google in order to rapidly develop big data analytic applications on distributed computing systems. Even though the Map/Reduce paradigm had a game changing impact on certain ...
    • Design and evaluation of a new transaction execution model for multidatabase systems 

      Devirmiş, T.; Ulusoy, Özgür (Elsevier, 1997)
      In this paper, we present a new transaction execution model that captures the formalism and semantics of various extended transaction models and adopts them to a multidatabase system (MDBS) environment. The proposed model ...
    • Efficiency and effectiveness of XML keyword search using a full element index 

      Atılgan, Duygu (Bilkent University, 2010)
      In the last decade, both the academia and industry proposed several techniques to allow keyword search on XML databases and document collections. A common data structure employed in most of these approaches is an inverted ...
    • Error-tolerant retrieval of trees 

      Oflazer, K. (IEEE, 1997)
      We present an efficient algorithm for retrieving from a database of trees, all trees that differ from a given query tree by a small number additional or missing leaves, or leaf label changes. It has natural language ...
    • Partial evaluation of queries for bit-sliced signature files 

      Kocberber, S.; Can, F. (Elsevier, 1996)
      Our research extends the bit-sliced signature organization by introducing a partial evaluation approach for queries. The partial evaluation approach minimizes the response time by using a subset of the on-bits of the query ...
    • Prosody-based automatic segmentation of speech into sentences and topics 

      Shriberg, E.; Stolcke, A.; Hakkani-Tür, D.; Tür, G. (Elsevier, 2000)
      A crucial step in processing speech audio data for information extraction, topic detection, or browsing/playback is to segment the input into sentence and topic units. Speech segmentation is challenging, since the cues ...
