    • Automatic ranking of information retrieval systems using data fusion 

      Nuray, R.; Can, F. (Elsevier Ltd, 2006-05)
      Measuring effectiveness of information retrieval (IR) systems is essential for research and development and for monitoring search quality in dynamic environments. In this study, we employ new methods for automatic ranking ...
    • Cache-based query processing for search engines 

      Cambazoglu, B. B.; Altıngovde, I. S.; Ozcan, R.; Ulusoy, Ö. (Association for Computing Machinery, 2012-11-01)
      In practice, a search engine may fail to serve a query due to various reasons such as hardware/network failures, excessive query load, lack of matching documents, or service contract limitations (e.g., the query rate limits ...
    • Compiler directed network-on-chip reliability enhancement for chip multiprocessors 

      Ozturk, O.; Kandemir, M.; Irwin, M. J.; Narayanan, S.H. K. (Association for Computing Machinery, 2010-04)
      Chip multiprocessors (CMPs) are expected to be the building blocks for future computer systems. While architecting these emerging CMPs is a challenging problem on its own, programming them is even more challenging. As the ...
    • Evolution of web search results within years 

      Altingovde, I. S.; Ozcan, R.; Ulusoy, O. (2011)
      We provide a first large-scale analysis of the evolution of query results obtained from a real search engine at two distant points in time, namely, in 2007 and 2010, for a set of 630,000 real queries.
    • A model of boundedly rational learning in dynamic games 

      Aksoy, Hakan (Bilkent University, 1997)
      There are various computer-based algorithms about boundedly rational players’ learning how to behave in dynamic games, including classifier systems, genetic algorithms and neural networks. Some examples of studies using ...
    • My imaginary world: an analysis of styles in polish animation in terms of invention and experimentation 

      Brzozowska, Maria (Bilkent University, 2016-05)
      This thesis accompanies my short animation My Imaginary World. The paper explores experimentation with animation. The thesis looks at experimental animation; it’s meaning and explores whether there is a specific way of ...
    • Optimizing shared cache behavior of chip multiprocessors 

      Kandemir, M.; Muralidhara, S.P.; Narayanan, S.H.K.; Zhang, Y.; Ozturk O. (2009)
      One of the critical problems associated with emerging chip multiprocessors (CMPs) is the management of on-chip shared cache space. Unfortunately, single processor centric data locality optimization schemes may not work ...
    • Querying web metadata: Native score management and text support in databases 

      Özsoyoǧlu, G.; Altingövde, I. S.; Al-Hamdani, A.; Özel, S. A.; Ulusoy, Ö.; Özsoyoǧlu, Z. M. (Association for Computing Machinery, 2004)
      In this article, we discuss the issues involved in adding a native score management system to object-relational databases, to be used in querying Web metadata (that describes the semantic content of Web resources). The Web ...
    • Second chance: a hybrid approach for dynamic result caching and prefetching in search engines 

      Ozcan, R.; Altingovde, I. S.; Cambazoglu, B. B.; Ulusoy, O. (Association for Computing Machinery, 2013-12)
      Web search engines are known to cache the results of previously issued queries. The stored results typically contain the document summaries and some data that is used to construct the final search result page returned to ...
