Provenance in Web Feed Mash-Up Systems

The recent emergence of web 2.0 technologies and rich internet applications is driving the development of a new class of applications that combines data from diverse sources which we refer to as “mash-ups.” One of the most popular mash-ups comes in the form of web feed mash-ups relying on syndication technologies such as RSS and Atom. This kind of mash-ups aggregates web feeds derived from multiple news websites or blogs and then timely presents them in a single interface. In such systems, it is difficult to know exactly how feed results in data mash-ups are generated. In particular, it is difficult for users to make determinations about whether information is trusted. Therefore, it is necessary that web feed mash-ups have to support a mechanism that is capable of recording and querying provenance information - the information about the process that led to result data. In this paper, the author proposes a provenance tracking solution that enables provenance functionality to be facilitated in web feed mash-ups. He demonstrates how the provenance of feed mash-up results to be determined by means of a provenance query algorithm. To tackle the storage problem resulting from the persistence of intermediate web feeds, a novel storage optimization method is introduced. Finally, the author evaluates his provenance solution in terms of storage consumption for provenance collection, demonstrating significant reductions in storage size and achieving reasonable storage overheads.

Content-Based Publish/Subscribe System for Web Syndication

Content syndication has become a popular way for timely delivery of frequently updated information on the Web. Today, web syndication technologies such as RSS or Atom are used in a wide variety of applications spreading from large-scale news broadcasting to medium-scale information sharing in scientific and professional communities. However, they exhibit serious limitations for dealing with information overload in Web 2.0. There is a vital need for efficient real-time filtering methods across feeds, to allow users to effectively follow personally interesting information. We investigate in this paper three indexing techniques for users’ subscriptions based on inverted lists or on an ordered trie for exact and partial matching. We present analytical models for memory requirements and matching time and we conduct a thorough experimental evaluation to exhibit the impact of critical parameters of realistic web syndication workloads.

An Access Dispersion Algorithm for Dynamic Contents Delivery

With increasing use of internet services on mobile terminals, the importance of contents syndication technology is growing in order to provide services desired by users. In general, client-initiated periodic update environment may lower the efficiency of resource use because the network is overloaded by the simultaneous connection of multiple clients. In order to solve this problem, we propose an access dispersion algorithm that can disperse multiple connections by providing each of multiple clients with a different next access time.

사용자 중심의 블로그 정보 검색 기법

최근 빠른 주기로 많은 양의 새로운 정보가 생성되기 때문에, 사용자 중심의 정보 검색을 위해 RSS라는 신디케이션 기술이 제공되고 있다. RSS는 새롭게 갱신된 콘텐츠를 자동으로 전달받을 수 있어 신규 정보를 찾기 위해 사이트에 지속적으로 접근하지 않아도 된다. 본 논문에서는 블로그 정보 검색을 위해 RSS 문서의 주소를 수집하는 수집기와 사용자 질의에 따른 RSS 문서의 순위결정 방법을 제안한다. 제안하는 정보 검색 기법을 이용하면 사용자가 RSS 문서를 효과적으로 검색할 수 있다. Due to the recent tremendous growth of internet information, RSS, syndication technology provides internet users with a user-friendly information search. RSS enables you to automatically receive newly updated contents, so users do not need to constantly access web sites to obtain new information. This paper proposes the way of managing the web crawler, which collects the sites of RSS documents and helps the users efficiently use the RSS documents. And it also suggests the proper way of ranking the RSS documents based on the users' popularity. Users can efficiently search out the documents they need by using the proposed information searching methods.

Internet-Based Dissemination of Educational Video Presentations: A Primer in Video Podcasting

Video "podcasting" is an Internet-based publication and syndication technology that is defined as the process of capturing, editing, distributing, and downloading audio, video, and general multimedia productions. The expanded capacity for visual components allows radiologists to view still and animated media. These image-viewing characteristics and the ease of widespread delivery are well suited for radiologic education. This article presents detailed information about how to generate and distribute a video podcast using a Macintosh platform.

Does Web Syndication Technology Facilitate Investor Decision Making?

ABSTRACT: Web syndication is an emerging technology that “feeds” website information to subscribers. It allows Internet users to collect, organize, and view frequently updated information from multiple sources effortlessly. We investigated whether using web syndication technology helps nonprofessional investors acquire and integrate relevant information which has been updated frequently and is from multiple sources when the investors make decisions. We obtained evidence of this new technology's effects using an experiment where subjects visited either a syndicated web page or a nonsyndicated web page and assessed two fictional companies' critical financial ratios and investment perspectives. Our results indicate that individuals who use syndication technology are more effective in acquiring relevant information updated frequently and integrating information for investment decision making than individuals who do not use such technology. The results suggest that web syndication may be used as an information integration tool for nonprofessional investors in assisting their decision making.

Applications of RSS in Health Sciences Libraries

SUMMARY RSS is a syndication technology based on XML. RSS can be used for current awareness and as a SDI tool for clinicians and information professionals alike, delivering syndicated information as it becomes available from blogs, databases, and other online information sources. RSS can also be used to create dynamic content on health sciences library Web sites. With a great number of free tools available, RSS can be integrated into library services simply and seamlessly, enhancing library service offerings at extremely low cost to health sciences libraries.

Follow the St. Petersburg College Library as they Enter the Blogosphere

Abstract Libraries throughout history have utilized some method of communicating resources and services to their communities. Verbal communication progressed into newsletters, event calendars, bookmarks, and posters. More recently, technological advancements have allowed individuals to communicate ideas beyond the confined pages of a book or newsletter and into the vastness of cyberspace. Web logs, or blogs, are considered a “new” cultural phenomenon, and they certainly have impacted the mainstream media. Libraries are, again, on the cutting edge of this technology. So, follow St. Petersburg College Library as they enter into the blogosphere. This article will outline the development of St. Petersburg College's Library Blog (SPCLB)-including the mission of the blog, posting procedures and policies, selecting blog authoring/management software, the overall template design and code changes, and unique site visit statistics, all while introducing syndication technology and other blogging advancements, such a...
