In the world of information, internet becomes the most important information source. However, internet contains vast amount of information and this information is not filtered. In such an environment, the people who seek for an information is overwhelmed in the alternatives that s/he can reach via the web. Recommender systems have their real importance in this kind of situations. To overcome said overwhelming problems, recommender systems are developed to determine the people needs and to recommend suitable alternatives to them. The current recommendation methods are classified under three main categories: collaborative filtering, content-based and hybrid approaches. Classical content-based recommendation approaches include the content information of the items. In this thesis work, we propose a user preference boosted content-based recommendation methodology. In addition to the items content information, we aimed to define a novel approach to the problem of including user’s preference information to the information filtering process. The novel solution that we explained in this thesis work uses the users past like and dislike rate information related to the specific items to predict recommendation scores related to the unseen items. The results which we obtained by implementing the proposed user preference boosted content based recommendation approach indicates that; by including the users' preference information to the items content information more accurate recommendations can be done and more reliable results can be gathered. We present the implementation details and comparative evaluation results of the proposed novel approach in this thesis.

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...
Tweet recommendation under user interest modeling with named entity recognition
Karatay, Deniz; Karagöz, Pınar; Department of Computer Engineering (2014)
Twitter has become one of the most important communication channels with its ability of providing the most up-to-date and newsworthy information. Considering wide use of Twitter as the source of information, reaching an interesting tweet for a user among a bunch of tweets is challenging. As a result of huge amount of tweets sent per day by hundred millions of users, information overload is inevitable. In order for users to reach the information that they are interested easily, recommendation of tweets is an...
Personalized time-aware outdoor activity recommendation system
Rahimiaghdam, Shakiba; Karagöz, Pınar; Mutlu, Alev; Department of Computer Engineering (2015)
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 develo...
A Comparison of different recommendation techniques for a hybrid mobile game recommender system
Cabir, Hassane Natu Hassane; Alpaslan, Ferda Nur; Çakıcı, Ruket; Department of Computer Engineering (2012)
As information continues to grow at a very fast pace, our ability to access this information effectively does not, and we are often realize how harder is getting to locate an object quickly and easily. The so-called personalization technology is one of the best solutions to this information overload problem: by automatically learning the user profile, personalized information services have the potential to offer users a more proactive and intelligent form of information access that is designed to assist us ...
A hybrid recommendation system capturing the effect of time and demographic data
Oktay, Fulya; Alpaslan, Ferda Nur; Department of Computer Engineering (2010)
The information that World Wide Web (WWW) provides have grown up very rapidly in recent years, which resulted in new approaches for people to reach the information they need. Although web pages and search engines are indeed strong enough for us to reach what we want, it is not an efficient solution to present data and wait people to reach it. Some more creative and beneficial methods had to be developed for decreasing the time to reach the information and increase the quality of the information. Recommendat...
