An analysis of social networks based on tera-scale telecommunication datasets
(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 ... -
Analyzing developer contributions using artifact traceability graphs
(Bilkent University, 2020-12)Software artifacts are the by-products of the development process. Throughout the life cycle of a project, developers produce different artifacts such as source files and bug reports. To analyze developer contributions, we ... -
Cascade-aware partitioning of large graph databases
(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
(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. ... -
Efficient quantification of profile matching risk in social networks using belief propagation
(Springer Science and Business Media Deutschland GmbH, 2020)Many individuals share their opinions (e.g., on political issues) or sensitive information about them (e.g., health status) on the internet in an anonymous way to protect their privacy. However, anonymous data sharing has ... -
Embracing American culture: structures of social identity and social networks among first-generation biculturals
(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
(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 key developers using artifact traceability graphs
(Association for Computing Machinery, 2020)Developers are the most important resource to build and maintain software projects. Due to various reasons, some developers take more responsibility, and this type of developers are more valuable and indispensable for the ... -
Identifying the most valuable developers using artifact traceability graphs
(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
(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
(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
(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
(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
(Bilkent University, 2019-08)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 ... -
Profile matching across online social networks
(Springer Science and Business Media Deutschland GmbH, 2020)In this work, we study the privacy risk due to profile matching across online social networks (OSNs), in which anonymous profiles of OSN users are matched to their real identities using auxiliary information about them. ... -
Social networks and credit access in Indonesia
(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 ...
