The day mankind met with smart-phones, a new era started. Since then, daily mobile internet usage rates are increasing everyday and people have developed new habits like frequently sharing information (photo, video, location, etc.) on online social networks. Location Based Social Networks (LBSNs) are the platforms that empowers users to share place/location information with friends. As all other social networks, LBSNs aim to acquire more users with a smart friend recommendation. Solution for smart friend recommendation problem is studied under link prediction field by researchers. Check-in information is the main data for link prediction in LBSNs. Data extracted from check-in information plays vital role for predictor performance. In this study, we attempt to make use of detailed analysis of place category in order to exploit possible information gain enhancements through such semantic information. We proposed two new feature groups; Common Place Check-in Count Product Sum and Common Category Check-in Count Sum Product. For any link candidate pair; those features are calculated for each category. Use of new features improved the link prediction performance for multiple data subsets.

Examining the relationship between personality traits and nomophobia among preservice teachers Akhoroz, Mehmet; Yıldırım, İbrahim Soner; Department of Computer Education and Instructional Technology (2019) In the last decade, the uptake of mobile information and communication technologies, especially smartphones, has undoubtedly had a substantial impact on how people communicate, work, learn, entertain, and even live. While smartphones have obvious benefits due to the capabilities they provide, such as instant access to information and constant connectivity to family and friends, problems associated with smartphones constitute a growing concern for end users, parents, teachers, experts, and researchers. One s...
Cryptographic Misuse Detection Tools Koru, Emine Selin; Cenk, Murat; Gürkan Balıkçıoğlu, Pınar; Department of Cryptography (2021-9-24) Today digital devices are an inevitable part of our lives. We use these devices for things like sharing photos, communicating with friends, and exchanging money. All these actions need privacy. In fact, properly used cryptographic systems can fulfill this need for privacy. However, in some cases developers can make mistakes, because of the reason such as lack of knowledge about cryptography and hard usage of cryptographic APIs. Thus, cryptographic misuse detection has become a new field of study and tools h...
Development and improvement of analog circuit design: a message passing interface parallel computing approach with genetic algorithms Kalınlı, Adem; Aksu, Özgür (IOS Press, 2010-02-01) The world, we live and will live in the future, is Analog. Everything we can see, hear and perceive in life is Analog, from voice, music and seismic activity to visual perception, voice recognition and energy delivery. 20th Century scientists are still trying to understand and formulate world events. For this aim they have produced a system, which is different human machine language, name is Digital Systems. Digital Systems is only human known and used systems. If anything in the world is wanted to be done ...
Exploring the relationship between college students’ mobile phone affinity and their mobile phone usage Bilü, Hacer; Yıldırım, İbrahim Soner; Department of Information Systems (2017) Mobile phones have become a part of our everyday life thanks to being used anytime and anywhere. They offer many features to users, which have turned them into devices that used for much more than calling and messaging. Moreover, previous studies indicate that mobile phones have drawbacks for users as well as benefits. Users have become addicted to their mobile phones and they experience negative emotions in case of separation from them. In addition, the use of mobile phones directly/indirectly affects the ...
A SYSTEMATIC REVIEW ON SMART CITY SERVICES AND IOT-BASED TECHNOLOGIES Özkan Yıldırım, Sevgi (2019-03-21) Due to the technological developments, Internet of things (IoT) has become a real phenomenon. Accordingly, many IoT-based smart concepts appeared in our daily lives such as smart home, smart healthcare and smart city. There are several factors accelerating or hindering the adoption of such new services and concepts. So, the acceptance of IoT-based smart services is critical and should be analyzed carefully. In this study, we aimed to prepare a proper starting point for future studies on end user acceptance ...
