Every day millions of information available so to achieve information becomes harder. To get the correct information trusted web sites and search engines are used. Trusted web sites have links between themselves, and users can reach correct and relevant information. Search engines are using crawler to follow links between pages. The context available to such crawlers can guide the navigation of links with the goal of efficiently locating highly relevant target pages. Crawler takes seed pages from search engines and follows these links using multi-agents. After first search, the results are inserted to database and they are used for seed pages for another search. The aim is the get access more reliable information using more seed pages in a short time.Yayın The risk perception of it outsourcing in Turkey(Işık Üniversitesi, 2013-08-28) Bingöl, Erdem; Sevgi, Cüneyt; Işık Üniversitesi, Fen Bilimleri Enstitüsü, Enformasyon Teknolojileri Yüksek Lisans ProgramıThe competition in today's business is getting stronger each day. Due to its proven cost reduction potential the usage of Information Technology (IT) outsourcing and the flexibility it provided are among the attractive and effective features to both SMEs (Small Medium enterprises) and large enterprises. Most enterprises with different sizes decide to transfer some or all of their IT services to outsourcing vendors. Implementing IT outsourcing has some advantages such as decreasing time required to enter a market, increasing quality, enhancing customer satisfaction, and allowing an organization to focus on its core areas. However, the use of IT outsourcing comes with many risks which need to be carefully evaluated before any engagement. This thesis surveys the recent literature for the most important risk factors inherent to the IT outsourcing such as increase in expenses, increased dependence on outsourcing firm, confidentiality and communication problems, etc. Herein, we focus on identifying the IT outsourcing usage characteristics and understanding the perception of IT outsourcing risk factors by conducting a survey in both IT companies and IT departments of the companies in Turkey. The conducted data obtained by the survey is used to discover the variance among the management levels of IT personnel, in the perceived factors that may lead to IT outsourcing risks. We analyze the survey data and portrayed the current situation of risks of IT outsourcing perceived by IT practitioners in Turkey.Yayın Transforming Hacivat-Karagöz shadow play to an interactive-educational computer game(Işık Üniversitesi, 2014-04-21) Öğretmen, Okan Efe; Ünel, Gülay; Işık Üniversitesi, Fen Bilimleri Enstitüsü, Enformasyon Teknolojileri Yüksek Lisans ProgramıIt is a known fact that computer games are influential on cognitive performance and that they have a huge potential if used as learning tools. In this study, the aim is to design an educational computer game based on Hacivat-Karagöz play, i.e. a Turkish shadow theater play. Instead of a classic shadow theater play, the current design lets children direct the characters and tell their improvised story. The game is designed to be helpful for improving the social abilities of children and as a side benefit it can help for keeping this valuable tradition alive. In this study, the outline of this game is provided and the classic Hacivat-Karagöz characters are re-designed in 3D. The chosen interaction medium is Leap Motion. HCI of leap motion is tested and the results indicate that the designed UI is successful enough to let children simulate the basic shadow theater tools. The redesign of these 2D-shadow theater characters in 3D was one of the most challenging steps. In order to tackle the task at hand, artistic skills were found to be equally important as technical skills. Although the current design is sufficiently capable of what was initially required, the current game concept needs to be revised with people from different backgrounds in order to create a more elaborate educational tool and to take the developed concept a step further.Yayın Designing innovative applications using near field communications (NFC) technology(Işık Üniversitesi, 2012-01-26) Özdenizci Köse, Büşra; Coşkun, Vedat; Işık Üniversitesi, Fen Bilimleri Enstitüsü, Enformasyon Teknolojileri Yüksek Lisans ProgramıNowadays, there is a growing interest on rapid development and adoption of information technologies (IT) especially in contactless smart cards and mobile communication technologies.

Social network is a social structure including individuals or organizations and different types of relationships such as friendship, common interests, work, city, etc. The main factor that separates online social networks and social networks is: in the online case, there is no face to face interaction between the nodes of the network. Since the 1970s, the role of social networks in terms of illness, distress, disease and disability; and in understanding how people identify and respond to these crises, has become a mainstay of social and behavioral science research [3]. In this thesis, we investigated trust relationships and information passing in online social networks that focus on health. There is a significant amount of related work in this area conducted on consumer choice prediction, consumer influence factors and information on eBay, Amazon and other early adapter big e-commerce Web sites all over the world. In this thesis, we particularly focused on the content of a Web site called doktorsitesi.com. This is the largest online social network in Turkey related to health that is managed by professionals. We collected data from this domain and investigated how the work on information passing in social networks can be used in this domain.Yayın Clinical decision making system for early diagnosis of types of SMA disease(Işık Üniversitesi, 2019-07-29) Taner, Çağlayan Onur; Çavdaroğlu, Gülsüm Çiğdem; Işık Üniversitesi, Fen Bilimleri Enstitüsü, Enformasyon Teknolojileri Yüksek Lisans ProgramıSpinal muscular atrophy (SMA) is a strict neuromuscular disease that is the most common in infancy, and the third one among young people under 18 years.

In multi-agent systems; actors that interact with the system are modeled as software entities called "agents". These software agents can show autonomous and intelligent behaviour. Also when a supporting runtime environment (or platform) is available, agents show mobility and can move between interconnected platforms that form the system. With these properties agents try to satisfy the expectations of their respective owner actors by using their knowledge and belief bases (derived from the actors). An implementation of a multi-agent system can both be used for simulation purposes (by initialising agents based on reference test data) and as an actual information system by attaching agents to real world actors. This work aims at analysing a university as a complex social system and creating a corresponding multi-agent model. In the designed model academic and administrative units and students are represented by intelligent and mobile agents that can be implemented using JADE multi-agent system development framework. To provide a satisfactory mobile environment faculties and administrative units are de ned to have their own (separate) agent platforms.
