DOBBS: Towards a Comprehensive Dataset to Study the Browsing Behavior of Online Users

The investigation of the browsing behavior of users provides useful information to optimize web site design, web browser design, search engines offerings, and online advertisement. This has been a topic of active research since the Web started and a large body of work exists. However, new online services as well as advances in Web and mobile technologies clearly changed the meaning behind "browsing the Web" and require a fresh look at the problem and research, specifically in respect to whether the used models are still appropriate. Platforms such as YouTube, Netflix or last.fm have started to replace the traditional media channels (cinema, television, radio) and media distribution formats (CD, DVD, Blu-ray). Social networks (e.g., Facebook) and platforms for browser games attracted whole new, particularly less tech-savvy audiences. Furthermore, advances in mobile technologies and devices made browsing "on-the-move" the norm and changed the user behavior as in the mobile case browsing is often being influenced by the user's location and context in the physical world. Commonly used datasets, such as web server access logs or search engines transaction logs, are inherently not capable of capturing the browsing behavior of users in all these facets. DOBBS (DERI Online Behavior Study) is an effort to create such a dataset in a non-intrusive, completely anonymous and privacy-preserving way. To this end, DOBBS provides a browser add-on that users can install, which keeps track of their browsing behavior (e.g., how much time they spent on the Web, how long they stay on a website, how often they visit a website, how they use their browser, etc.). In this paper, we outline the motivation behind DOBBS, describe the add-on and captured data in detail, and present some first results to highlight the strengths of DOBBS

CHORUS Deliverable 2.2: Second report - identification of multi-disciplinary key issues for gap analysis toward EU multimedia search engines roadmap

After addressing the state-of-the-art during the first year of Chorus and establishing the existing landscape in multimedia search engines, we have identified and analyzed gaps within European research effort during our second year. In this period we focused on three directions, notably technological issues, user-centred issues and use-cases and socio- economic and legal aspects. These were assessed by two central studies: firstly, a concerted vision of functional breakdown of generic multimedia search engine, and secondly, a representative use-cases descriptions with the related discussion on requirement for technological challenges. Both studies have been carried out in cooperation and consultation with the community at large through EC concertation meetings (multimedia search engines cluster), several meetings with our Think-Tank, presentations in international conferences, and surveys addressed to EU projects coordinators as well as National initiatives coordinators. Based on the obtained feedback we identified two types of gaps, namely core technological gaps that involve research challenges, and “enablers”, which are not necessarily technical research challenges, but have impact on innovation progress. New socio-economic trends are presented as well as emerging legal challenges

A Privacy Protection in Personalized Web Search for Knowledge Mining: A Survey

The web search engines (e.g. Google, Yahoo etc.) help the users to find required useful information on the World Wide Web (WWW). But it has become increasingly difficult to get the expected results from the web search engine because contentsare available in web is very vast and ambiguous.Due to tremendous data opportunities in the internet, the privacy protection is very essential to preserve user search behaviors and their profiles. In this paper system present a novel protocol specially designed to protect the users’ privacy in front of web search profiling. Personalized web search (PWS) has demonstrated its effectiveness in improving the quality of various search services on the Internet. Our runtime generalization aims at striking a balance between two predictive metrics that evaluate the utility of personalization and the privacy risk of exposing the generalized profile. System proposed two greedy algorithms namely GreedyDP and GreedyIL. These two algorithms are used for runtime generalization.The proposed protocol preserves the privacy of the individuals who deal with a web search engine.System provides a distorted user profile to the web search engine. It offers implementation details and computational and communication results that show that the proposed protocol improves the existing solutions in terms of query delay

Privacy preserving cooperative computation for personalized web search applications

With the emergence of connected objects and the development of Artificial Intelligence (AI) mechanisms and algorithms, personalized applications are gaining an expanding interest, providing services tailored to each single user needs and expectations. They mainly rely on the massive collection of personal data generated by a large number of applications hosted from different connected devices. In this paper, we present CoWSA, a privacy preserving Cooperative computation framework for personalized Web Search peripheral Applications. The proposed framework is multi-fold. First, it provides the empowerment to end-users to control the disclosed personal data to third parties, while leveraging the trade-off between privacy and utility. Second, as a decentralized solution, CoWSA mitigates single points of failures, while ensuring the security of queries, the anonymity of submitting users, and the incentive of contributing nodes. Third, CoWSA is scalable as it provides acceptable computation and communication costs compared to most closely related schemes

CHORUS Deliverable 3.3: Vision Document - Intermediate version

The goal of the CHORUS vision document is to create a high level vision on audio-visual search engines in order to give guidance to the future R&D work in this area (in line with the mandate of CHORUS as a Coordination Action). This current intermediate draft of the CHORUS vision document (D3.3) is based on the previous CHORUS vision documents D3.1 to D3.2 and on the results of the six CHORUS Think-Tank meetings held in March, September and November 2007 as well as in April, July and October 2008, and on the feedback from other CHORUS events. The outcome of the six Think-Thank meetings will not just be to the benefit of the participants which are stakeholders and experts from academia and industry – CHORUS, as a coordination action of the EC, will feed back the findings (see Summary) to the projects under its purview and, via its website, to the whole community working in the domain of AV content search. A few subjections of this deliverable are to be completed after the eights (and presumably last) Think-Tank meeting in spring 2009

CHORUS Deliverable 3.4: Vision Document

The goal of the CHORUS Vision Document is to create a high level vision on audio-visual search engines in order to give guidance to the future R&D work in this area and to highlight trends and challenges in this domain. The vision of CHORUS is strongly connected to the CHORUS Roadmap Document (D2.3). A concise document integrating the outcomes of the two deliverables will be prepared for the end of the project (NEM Summit)

Internet Nondiscrimination Principles: Commercial Ethics for Carriers and Search Engines

Unaccountable power at any layer of online life can stifle innovation elsewhere. Dominant search engines rightly worry that carriers will use their control of the physical layer of internet infrastructure to pick winners among content and application providers. Though they advocate net neutrality, they have been much less quick to recognize the threat to openness and fair play their own practices may pose. Just as dominant search engines fear an unfairly tiered online world, they should be required to provide access to their archives and indices in a nondiscriminatory manner. If dominant search engines want carriers to disclose their traffic management tactics, they should submit to regulation that bans stealth marketing and reliably verifies the absence of the practice. Finally, search engines\u27 concern about the applications and content disadvantaged by carrier fast-tracking should lead them to provide annotation remedies to indexed sites whose marks have been unfairly occluded by the search process. Fair competition online demands common commercial ethics for both dominant search engines and dominant carriers

Filtering, Piracy Surveillance and Disobedience

There has always been a cyclical relationship between the prevention of piracy and the protection of civil liberties. While civil liberties advocates previously warned about the aggressive nature of copyright protection initiatives, more recently, a number of major players in the music industry have eventually ceded to less direct forms of control over consumer behavior. As more aggressive forms of consumer control, like litigation, have receded, we have also seen a rise in more passive forms of consumer surveillance. Moreover, even as technology has developed more perfect means for filtering and surveillance over online piracy, a number of major players have opted in favor of “tolerated use,” a term coined by Professor Tim Wu to denote the allowance of uses that may be otherwise infringing, but that are allowed to exist for public use and enjoyment. Thus, while the eventual specter of copyright enforcement and monitoring remains a pervasive digital reality, the market may fuel a broad degree of consumer freedom through the toleration or taxation of certain kinds of activities. This Article is meant largely to address and to evaluate these shifts by drawing attention to the unique confluence of these two important moments: the growth of tolerated uses, coupled with an increasing trend towards more passive forms of piracy surveillance in light of the balance between copyright enforcement and civil liberties. The content industries may draw upon a broad definition of disobedience in their campaigns to educate the public about copyright law, but the market’s allowance of DRM-free content suggests an altogether different definition. The divide in turn between copyright enforcement and civil liberties results in a perfect storm of uncertainty, suggesting the development of an even further division between the role of the law and the role of the marketplace in copyright enforcement and innovation, respectively
