The new growing generation of the communication technology has been gaining enormous popularity in the past few years. Location-based social network as one of the platforms in this field, has been providing services and facilities to enhance user experience to explore their surrenders and new places. Among current services, point of interest (POI) recommendation and activity recommendation draws significant attention of users, which makes it a potential field of the study. However, despite of all the developments performed in this field, activity recommendation system still requires further improvements, since only a few related studies concentrated on this topic so far. In order to develop the activity recommendation system, we present two approaches using different ideas by extending existing location-based collaborative filtering (CF) recommendation models. One of them focuses on the temporal feature of the data and the other one emphasizes on the correlation between activities to estimate the probability of selecting each activity. We evaluated our systems on a medium-scale real data set gained by the combination of the Gowalla and Foursqaure. The experimental results confirm that both our proposed methods remarkably outperform the basic CF model. In addition, we study several extensions on the location-based techniques as the minor contributions of this thesis.

A Context-aware application recommendation system for mobile device users
Bayram, Gamze; Koçyiğit, Altan; Department of Information Systems (2015)
Development of smartphones and applications has opened a whole new world for mobile device users. Although this new world has many benefits due to a large diversity, regarding specific application domains, it is getting more complex day by day. In this study, a context-aware application recommendation system that recognizes the situation of users, predicts, and recommends the interactions that are likely to happen by the users in their specific context is developed. The proposed system is based on a hybridi...
Improved probabilistic matrix factorization model for sparse datasets /
Ar, Yılmaz; Taşkaya Temizel, Tuğba; Department of Information Systems (2014)
The amount of information on the World Wide Web has increased significantly owing to advancing web and information technologies. This has made it difficult for users to obtain relevant and useful information thus there is a need for information filtering. Recommender Systems (RS) have emerged as a technique to overcome the problem. Collaborative Filtering (CF) that is one of the widely used RS approaches aims to predict users’ preference concerning an item. The main idea behind CF is the users who agreed in...
A novel user activity prediction model for context aware computing systems
Peker, Serhat; Koçyiğit, Altan; Department of Information Systems (2011)
In the last decade, with the extensive use of mobile electronic and wireless communication devices, there is a growing need for context aware applications and many pervasive computing applications have become integral parts of our daily lives. Context aware recommender systems are one of the popular ones in this area. Such systems surround the users and integrate with the environment; hence, they are aware of the users' context and use that information to deliver personalized recommendations about everyday ...
GUI testing of android applications: a systematic mapping
Aydın, Muzaffer; Betin Can, Aysu; Garousi, Vahid; Department of Information Systems (2014)
Popularity of mobile devices is increasing rapidly all around the world. These devices can be used on various systems which are commonly used by the society. These systems are predicted to overtake desktop platform's popularity in the near future. Therefore the quality of mobile applications has vital importance. High quality applications can only be developed with good testing environments. Considering that multi-featured mobile applications have complex user interfaces, we decided to focus on graphical us...
E-government adoption model based on theory of planned behavior: empirical investigation
Kanat, İrfan Emrah; Özkan Yıldırım, Sevgi; Department of Information Systems (2009)
The e-government phenomena has become more important with the ever increasing number of implementations world wide. A model explaining the e-government adoption and the related measurement instrument a survey had been developed and validated in this study. In a post technology acceptance model (TAM) approach, theory of planned behavior (TPB) was extended to t the requirements of e-government context. The adoption of student loans service of the higher education student loans and accommodation association...
