      Can, E. F.; Can, F.; Duygulu, P.; Kalpakli, M. (De Gruyter Akademie Forschung, 2014)
      Authorship attribution and identifying time period of literary works are fundamental problems in quantitative analysis of languages. We investigate two fundamentally different machine learning text categorization methods, ...
    • Automatic performance evaluation of Web search engines 

      Can, F.; Nuray, R.; Sevdik, A. B. (Elsevier, 2004)
      Measuring the information retrieval effectiveness of World Wide Web search engines is costly because of human relevance judgments involved. However, both for business enterprises and people it is important to know the most ...
    • 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 ...
    • Automatic tag expansion using visual similarity for photo sharing websites 

      Sevil, S. G.; Kucuktunc, O.; Duygulu, P.; Can, F. (Springer New York LLC, 2010)
      In this paper we present an automatic photo tag expansion method designed for photo sharing websites. The purpose of the method is to suggest tags that are relevant to the visual content of a given photo at upload time. ...
    • Change of word characteristics in 20th-century Turkish literature: a statistical analysis 

      Can, F.; Patton, J. M. (Routledge, 2010)
      This article provides a century-wide quantitative analysis of the Turkish literature using 40 novels of 40 authors. We divide the century into four eras or quarter-centuries; allocate 10 novels to each era, and partition ...
    • Chat mining: predicting user and message attributes in computer-mediated communication 

      Kucukyilmaz T.; Cambazoglu, B. B.; Aykanat, Cevdet; Can, F. (Elsevier Ltd, 2008-07)
      The focus of this paper is to investigate the possibility of predicting several user and message attributes in text-based, real-time, online messaging services. For this purpose, a large collection of chat messages is ...
    • Discovering story chains: a framework based on zigzagged search and news actors 

      Toraman C.; Can, F. (John Wiley and Sons Inc., 2017)
      A story chain is a set of related news articles that reveal how different events are connected. This study presents a framework for discovering story chains, given an input document, in a text collection. The framework has ...
    • Efficiency and effectiveness of query processing in cluster-based retrieval 

      Can, F.; Altingövde I.S.; Demir, E. (Elsevier, 2004)
      Our research shows that for large databases, without considerable additional storage overhead, cluster-based retrieval (CBR) can compete with the time efficiency and effectiveness of the inverted index-based full search ...
    • A front-page news-selection algorithm based on topic modelling using raw text 

      Toroman, C.; Can, F. (Sage Publications Ltd., 2015)
      Front-page news selection is the task of finding important news articles in news aggregators. In this study, we examine news selection for public front pages using raw text, without any meta-attributes such as click counts. ...
    • Incremental cluster-based retrieval using compressed cluster-skipping inverted files 

      Altingovde, I. S.; Demir, E.; Can, F.; Ulusoy, Özgür (Association for Computing Machinery, 2008-06)
      We propose a unique cluster-based retrieval (CBR) strategy using a new cluster-skipping inverted file for improving query processing efficiency. The new inverted file incorporates cluster membership and centroid information ...
    • Information retrieval on Turkish texts 

      Can, F.; Kocberber, S.; Balcik, E.; Kaynak, C.; Ocalan, H. C.; Vursavas, O. M. (John Wiley & Sons, Inc., 2008-02)
      In this study, we investigate information retrieval (IR) on Turkish texts using a large-scale test collection that contains 408,305 documents and 72 ad hoc queries. We examine the effects of several stemming options and ...
    • Message from the IEEE/ACM ASONAM 2012 general chairs 

      Can, F.; Carley, K. M.; King, I.; Yu, P. S. (2012)
    • New event detection and topic tracking in Turkish 

      Can, F.; Kocberber, S.; Baglioglu, O.; Kardas, S.; Ocalan, H. C.; Uyar, E. (John Wiley & Sons, Inc., 2010)
      Topic detection and tracking (TDT) applications aim to organize the temporally ordered stories of a news stream according to the events. Two major problems in TDT are new event detection (NED) and topic tracking (TT). These ...
    • Novelty detection for topic tracking 

      Aksoy, C.; Can, F.; Kocberber, S. (John Wiley & Sons, Inc., 2012)
      Multisource web news portals provide various advantages such as richness in news content and an opportunity to follow developments from different perspectives. However, in such environments, news variety and quantity can ...
    • Optimization of signature file parameters for databases with varying record lengths 

      Kocberber, S.; Can, F.; Patton, J. M. (Oxford University Press, 1999)
      For signature files we propose a new false drop estimation method for databases with varying record lengths. Our approach provides more accurate estimation of the number of false drops by considering the lengths of individual ...
    • 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 ...
