    • Generic text summarization for Turkish 

      Kutlu, M.; Cığır, C.; Cicekli, I. (Oxford University Press, 2010)
      In this paper, we propose a generic text summarization method that generates summaries of Turkish texts by ranking sentences according to their scores. Sentence scores are calculated using their surface-level features, and ...
    • Histogram of oriented rectangles: a new pose descriptor for human action recognition 

      İkizler, N.; Duygulu, P. (Elsevier BV, 2009-09-02)
      Most of the approaches to human action recognition tend to form complex models which require lots of parameter estimation and computation time. In this study, we show that, human actions can be simply represented by pose ...
    • Image classification using subgraph histogram representation 

      Özdemir, Bahadır; Aksoy, Selim (IEEE, 2010)
