With Aard- versus a village suggest some useful principles for designing vark, users ask a question, either by instant message, email, a social search engine. In a library, people use keywords to web input, text message, or voice. Aardvark then routes the search, the knowledge base is created by a small number of question to the person in the user’s extended social network content publishers before the questions are asked, and trust most likely to be able to answer that question. As compared is based on authority. In a village, by contrast, people use to a traditional web search engine, where the challenge lies natural language to ask questions, answers are generated in in finding the right document to satisfy a user’s information real-time by anyone in the community, and trust is based need, the challenge in a social search engine like Aardvark on intimacy. These properties have cascading effects — for lies in finding the right person to satisfy a user’s information example, real-time responses from socially proximal respon- need. Further, while trust in a traditional search engine is ders tend to elicit (and work well for) highly contextualized based on authority, in a social search engine like Aardvark, and subjective queries. For example, the query“Do you have trust is based on intimacy. -

Abstract The Web is increasingly important for all aspects of our society, culture and economy. Web archiving is the process of gathering digital materials from the Web, ingesting it, ensuring that these materials are preserved in an archive, and making the collected materials available for future use and research. Web archiving is a difficult problem due to organizational and technical reasons. We focus on the technical aspects of Web archiving. -

Detecting Malicious Websites with Low-Interaction Honeyclients
Monkey-Spider: Detecting Malicious Websites with Low-Interaction Honeyclients Ali Ikinci Thorsten Holz Felix Freiling University of Mannheim Mannheim, Germany Abstract: Client-side attacks are on the rise: malicious websites that exploit vulner- abilities in the visitor’s browser are posing a serious threat to client security, compro- mising innocent users who visit these sites without having a patched web browser. Currently, there is neither a freely available comprehensive database of threats on the Web nor sufficient freely available tools to build such a database. In this work, we in- troduce the Monkey-Spider project [Mon]. Utilizing it as a client honeypot, we portray the challenge in such an approach and evaluate our system as a high-speed, Internet- scale analysis tool to build a database of threats found in the wild. Furthermore, we evaluate the system by analyzing different crawls performed during a period of three months and present the lessons learned. 1 Introduction The Internet is growing and evolving every day. More and more people are becoming part of the so-called Internet community. With this growth, also the amount of threats for these people is increasing. Online criminals who want to destroy, cheat, con others, or steal goods are evolving rapidly [Ver03]. Currently, there is no comprehensive and free database to study malicious websites found on the Internet. Malicious websites are websites which have any kind of content that could be a threat for the security of the clients requesting these sites. For example, a malicious website could exploit a vulnerability in the visitor’s web browser and use this to compromise the system and install malware on it. -
The Importance of RSS in the Exchange of Medical Information
The Importance of RSS in the Exchange of Medical Information Frankie Dolan and Nancy Shepherd 1 MedWorm.com [email protected] 2 Shepherd Research LLC. [email protected] Abstract. This paper investigates the role of RSS in providing a so- lution to the problem of medical information overload, speeding up the dissemination of information and improving communications between all those with an interest in health. It compares the exchange and use of medical information on the Internet before and after the use of RSS and also shares a vision for the future, using MedWorm, a medical search engine and RSS newsfeed provider, as an example. The conclusion high- lights how RSS has opened a new dimension of information exchange which has the potential to enable giant steps forward in the ¯eld of medicine. To realise its full potential, both publishers and users of medi- cal information need to recognise the importance of RSS, ensure thought- ful implementation of RSS feeds to announce publication, and provide for education regarding its everyday use. 1 Introduction The Internet has enabled access to a wealth of in depth research and medically related information not previously available, but it has also given rise to a new set of problems for todays physician. Medical practitioners are now inundated with information[1], short of time [2] and yet obliged to keep up to date at all times with the very latest developments. Patients are researching their own conditions and often expect their doctors to have expert and recent knowledge on a vast range of topics. This paper briefly describes RSS (really simple syndication) [3] and inves- tigates the way in which RSS is starting to provide a solution to the problem of medical information overload, speeding up the dissemination of information across the Internet and improving communications between all those with an interest in health.
