Nowadays, microblogging services are seen as a source of information. It brings us a question. Can we trust information in a microblogging service? In this paper, we focus on one of the popular microblogging services, Twitter, and try to answer which information in Twitter is credible. Newsworthiness, importance and correctness are the dimensions to be measured in this study. We propose a hybrid credibility analysis which combines feature based and graph based approaches. Our model is based on three types of structures, which are tweet, user and topic. Initially, we use feature based learning to construct a prediction model. In the second step, we use the results of this model as input to authority transfer and further refine the credibility scores for each type of node. The same process is used for measuring each of the dimensions of newsworthiness, importance and correctness. Experimental results show that the proposed hybrid method improves the prediction accuracy for each of these credibility dimensions.

A study for the requirements of a quality maturity framework for it facilities in organizations: a case for quality assessment in Turkish institutions Oray, Emre; Arifoğlu, Ali; Department of Information Systems (2010) Nowadays, almost all organizations use information technologies (IT) in some extent that they have gained many advantages from it. However, the wrong management of IT processes may cause big problems for organizations. It is first required to reach the quality to successfully govern IT and its processes. At this point, it is essential to have a quality maturity framework that organizations could use to follow a logical path in achieving quality. This thesis represents a study for determining the general qua...
A Hybrid method for toponym recognition on informal Turkish text Sağcan, Meryem; Karagöz, Pınar; Department of Computer Engineering (2014) Since accessing the Internet is getting easier and people are more willing to share information on the Internet than the previous generations, the data on such kind of reachable sources are growing very rapidly day by day. Moreover, because of the popularity and widely usage of those sources, the information which researchers and organizations are interested in can be found somewhere in these data collection. The purpose of Information Extraction (IE) is to analyze this information cloud and to extract the ...
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...
A Context Aware Notification Architecture Based on Distributed Focused Crawling in the Big Data Era AKYOL, MEHMET ALİ; Gökalp, Mert Onuralp; Kayabay, Kerem; Eren, Pekin Erhan; Koçyiğit, Altan (2017-09-08) The amount of data created in various sources over the Web is tremendously increasing. Trying to keep track of relevant sources is an increasingly time-consuming task. The traditional way of accessing information over the Web is pull-based. Users need to query data sources in certain time intervals where an important piece of information can be lately recognized or even missed completely. Technologies including RSS help users to get push-based notifications from websites. Discovering the relevant informatio...
