    • An analysis of social networks based on tera-scale telecommunication datasets 

      Aksu, Hidayet; Körpeoğlu, İbrahim; Ulusoy, Özgür (IEEE Computer Society, 2019)
      With the popularization of mobile phone usage, telecommunication networks have turned into a socially binding medium. Considering the traces of human communication held inside these networks, telecommunication networks are ...
    • Cascade-aware partitioning of large graph databases 

      Demirci, Gündüz Vehbi; Ferhatosmanoğlu, H.; Aykanat, Cevdet (Springer, 2019)
      Graph partitioning is an essential task for scalable data management and analysis. The current partitioning methods utilize the structure of the graph, and the query log if available. Some queries performed on the database ...
    • The effect of social networks on the quality of political thinking 

      Erisen, E.; Erisen, C. (Wiley-Blackwell Publishing, Inc., 2012)
      In this article we investigate the effect of social networks on the quality of political thinking. First, the article introduces new social network concepts into the literature and develops the corresponding measures. ...
    • Embracing American culture: structures of social identity and social networks among first-generation biculturals 

      Mok, A.; Morris, M. W.; Benet-Martínez, V.; Karakitapoğlu-Aygün, Z. (Sage Publications, 2007)
      This study examines the relationship between bicultural individuals' identity structure and their friendship network. A key dimension of identity structure for first-generation immigrants is the degree to which the secondary, ...
    • Estimating network structure via random sampling: cognitive social structures and the adaptive threshold method 

      Siciliano, M. D.; Yenigun, D.; Ertan, G. (Elsevier, 2012-10)
      This paper introduces and tests a novel methodology for measuring networks. Rather than collecting data to observe a network or several networks in full, which is typically costly or impossible, we randomly sample a portion ...
    • Identifying the most valuable developers using artifact traceability graphs 

      Çetin, H. Alperen (Association for Computing Machinery, Inc, 2019)
      Finding the most valuable and indispensable developers is a crucial task in software development. We categorize these valuable developers into two categories: connector and maven. A typical connector represents a developer ...
    • Integrating social factors into mobile local search 

      Kahveci, Basri (Bilkent University, 2015-08)
      As availability of internet access on mobile devices develops year after year, users have been able to make use of mobile internet and search services while on the go. Location information on these devices has enabled ...
    • Mathematical model of causal inference in social networks 

      Şimsek, Mustafa; Delibalta, İ.; Baruh, L.; Kozat, Süleyman Serdar (IEEE, 2016)
      In this article, we model the effects of machine learning algorithms on different Social Network users by using a causal inference framework, making estimation about the underlying system and design systems to control ...
    • A noncooperative dynamic game model of opinion dynamics in multilayer social networks 

      Niazi, Muhammad Umar B. (Bilkent University, 2017-08)
      How do people living in a society form their opinions on daily or prevalent topics? A noncooperative di erential (dynamic) game model of opinion dynamics, where the agents' motives are shaped by how susceptible they are ...
    • Online contextual influence maximization with costly observations 

      Saritac, A. O.; Karakurt, A.; Tekin, C. (Institute of Electrical and Electronics Engineers, 2018)
      In the Online Contextual Influence Maximization Problem with Costly Observations, the learner faces a series of epochs in each of which a different influence spread process takes place over a network. At the beginning of ...

      Sarıtaç, Anıl Ömer; Karakurt, Altuğ; Tekin, Cem (IEEE, 2019-06)
      In the online contextual influence maximization problem with costly observations, the learner faces a series of epochs in each of which a different influence spread process takes place over a network. At the beginning of ...
    • Partitioning models for scaling distributed graph computations 

      Demirci, Gündüz Vehbi (Bilkent University, 2019-09)
      The focus of this thesis is intelligent partitioning models and methods for scaling the performance of parallel graph computations on distributed-memory systems. Distributed databases utilize graph partitioning to provide ...
    • Social networks and credit access in Indonesia 

      Okten, C.; Osili, U. O. (Pergamon Press, 2004)
      In this paper, we investigate how family and community networks affect an individual's access to credit institutions using new data from the Indonesia Family Life Surveys. Our theoretical framework emphasizes the family ...
