    • Haber videolarında nesne tanıma ve otomatik etiketleme 

      Baştan, Muhammet; Duygulu, Pınar (IEEE, 2006-04)
      We propose a new approach to object recognition problem motivated by the availability of large annotated image and video collections. Similar to translation from one language to another, this approach considers the object ...
    • Language evolution and information theory 

      Ahlswede, R.; Arıkan, Erdal; Bäumer, L.; Deppe, C. (IEEE, 2004-06-07)
      The use of Nowak's model to study the language evolution and to settle a conjecture by Nowak was discussed. These models explained the ways by which natural selection can lead to the gradual emergence of human language. ...
    • Lexical cohesion based topic modeling for summarization 

      Ercan, Gönenç; Çiçekli, İlyas (Springer, 2008-02)
      In this paper, we attack the problem of forming extracts for text summarization. Forming extracts involves selecting the most representative and significant sentences from the text. Our method takes advantage of the lexical ...
    • On document relevance and lexical cohesion between query terms 

      Vechtomova, O.; Karamuftuoglu, M.; Robertson, S. E. (Elsevier, 2006)
      Lexical cohesion is a property of text, achieved through lexical-semantic relations between words in text. Most information retrieval systems make use of lexical relations in text only to a limited extent. In this paper ...
    • Query expansion with terms selected using lexical cohesion analysis of documents 

      Vechtomova, O.; Karamuftuoglu, M. (Elsevier Ltd, 2007-07)
      We present new methods of query expansion using terms that form lexical cohesive links between the contexts of distinct query terms in documents (i.e., words surrounding the query terms in text). The link-forming terms ...
    • Retrieval of Ottoman documents 

      Ataer, Esra; Duygulu, Pınar (ACM, 2006-10)
      There is a growing need to access historical Ottoman documents stored in large archives and therefore managing tools for automatic searching, indexing and transcription of these documents is required. In this paper, we ...
