Breaking the filter bubble: Democracy and design

It has been argued that the Internet and social media increase the number of available viewpoints, perspectives, ideas and opinions available, leading to a very diverse pool of information. However, critics have argued that algorithms used by search engines, social networking platforms and other large online intermediaries actually decrease...

Bursting the Filter Bubble: Democracy, Design, and Ethics

Online web services such as Google and Facebook started using personalization algorithms. Because information is customized per user by the algorithms of these services, two users who use the same search query or have the same friend list may get different results. Online services argue that by using personalization algorithms, they may show the...

Analyzing viewpoint diversity in twitter

Information diversity has a long tradition in human history. Recently there have been claims that diversity is diminishing in information available in social networks. On the other hand, some studies suggest that diversity is actually quite high in social networks such as Twitter. However these studies only focus on the concept of source...

Performance Testing of Data Delivery Techniques for AJAX Applications

Preprint of paper published in: Journal of Web Engineering (Rinton Press), 8 (4), 2009 AJAX applications are designed to have high user interactivity and low user-perceived latency. Real-time dynamic web data such as news headlines, stock tickers, and auction updates need to be propagated to the users as soon as possible. However, AJAX still...

An Adaptive Push/Pull Algorithm for AJAX Applications

Preprint of paper published in: AEWSE 2008 - Proceedings of the Third International Workshop on Adaptation and Evolution in Web Systems Engineering, 16 July 2008 Even though the AJAX paradigm helps web applications to become more responsive, AJAX alone does not provide an efficient mechanism for real-time data delivery. Use cases of applications...

Crawling AJAX by Inferring User Interface State Changes

Preprint of paper published in: ICWE 2008 - 8th International Conference on Web Engineering, 14-18 July 2008; doi:10.1109/ICWE.2008.24 AJAX is a very promising approach for improving rich interactivity and responsiveness of web applications. At the same time, AJAX techniques shatter the metaphor of a web "page" upon which general search crawlers...

A Comparison of Push and Pull Techniques for AJAX

AJAX applications are designed to have high user interactivity and low user-perceived latency. Real-time dynamic web data such as news headlines, stock tickers, and auction updates need to be propagated to the users as soon as possible. However, AJAX still suffers from the limitations of the Web’s request/response architecture which prevents...

Values in the filter bubble Ethics of Personalization Algorithms in Cloud Computing

Cloud services such as Facebook and Google search started to use personalization algorithms in order to deal with growing amount of data online. This is often done in order to reduce the “information overload”. User’s interaction with the system is recorded in a single identity, and the information is personalized for the user using this...
