Abstract: As people participate in the thousands of global conversations that comprise Usenet news, one thing they do is post their opinions of web resources. Phoaks is a collaborative filtering system that continuously parses, classifies, abstracts and tallies those opinions. About 3,500 users per day consult Phoaks web pages that reflect the results. Phoaks also features a general architecture for building similar collaborative filtering interfaces to conversational data. We report here on the Phoaks resource recommendation interface, the architecture, and the issues and experience that make up its rationale.

Abstract: Various methods of caching web resources include caching in accordance with a number of times accessed, a frequency of access, or a duration of access. One method of caching web resources includes the step of accessing a first web resource. The first web resource is cached, if no other web resource is accessed after a pre-determined period of time. Another method of caching web resources includes the step of accessing a first web resource. The first web resource is cached, if the first web resource is subsequently accessed more than a pre-determined number of times. Another method of caching web resources includes the step of accessing a plurality of web resources. The accessed web resources are cached as cached web resources in accordance with at least one of a number of times accessed, a frequency of access, or a duration of access. An apparatus comprises storage media containing caching logic for caching web resources. The caching logic includes instructions to cache selected web resources as cached web resources in accordance with at least one of a number of times accessed, a frequency of access, or a duration of access. The selected web resources correspond to a subset of a plurality of accessed web resources.

Abstract: This paper addresses the problems related to multipoint distribution of Web documents over Internet. We present a multicast Web application which allows the sharing of Web resources among a group of people by using the MBONE technology. We describe a general-purposed light-weight reliable multicast transport protocol (LRMP) which is an important building block of the application. We will also discuss other technical issues related to the design of such applications, such as caching, Web browser interface, and embedded objects.

Abstract: This tutorial shows you how to unlock the hidden resources of the Internet and the World Wide Web. After a description of its history, we demystify the Internet's terminology and procedures by exploring electronic mail, addressing, mail lists, news groups, and the World Wide Web. We illustrate Web use in two domains, personal and professional. In the personal domain we show a number of useful, time-saving resources for: travel and leisure, investments and finance; personal shopping; medicine; real estate; museums; weather; games; and finding, retrieving, and managing information on any topic whatsoever. In the professional domain we show how to access Web resources in such areas as elementary, secondary, and university-level education; computers; legal advice; libraries; news and current events; science and engineering; telecommunications, teleconferencing, telemedicine, and telecommuting. We close with a review of the "hot topics" of 1997: privacy and security, electronic payment systems, and low-cost and high speed Internet access.

Abstract: Motivated by the potential opportunities that lie in providing cooperation among Web-Servers, we propose a generic and scalable approach for dynamic server-interconnectivity, and present the WebRule framework which embodies this approach. WebRule is based on the Event Condition Action rule formalism, which enables to specify declaratively various modes of cooperation between Web servers, including synchronus vs. asynchronus interaction, on-line vs. off-line, and automatic chaining of cooperative actions. WebRule requires no centralized encoding, control or administration, thereby enabling to utilize and deploy Web resources in a truly decentralized manner. WebRule has been implemented in Java as a server plug-in, seamelessly integrated with standard Web server technology and protocols.

Abstract: In this paper we discuss some of the problems of the current Web and show how the introduction of object-orientation provides flexible and extensible solutions. Web resources become encapsulated as objects, with well-defined interfaces through which all interactions occur. The interfaces and their implementations can be inherited by builders of objects, and methods (operations) can be redefined to better suit the object. New characteristics, such as concurrency control and persistence, can be obtained by inheriting from suitable base classes, without necessarily requiring any changes to users of these resources. We describe the W3Object model which we have developed based upon these ideas, and show, through a prototype implementation, how we have used the model to address the problems of referential integrity and transparent object (resource) migration. We also give indications of future work.

Abstract: More and more, education is looking to connect up to global and community based resources to enrich learning. As schools begin to reach a critical mass of networked hardware and software resources, the path towards true pedagogical change becomes clearer. Access to the Internet and World Wide Web is becoming a top priority. The National Center for Education. Statistics, in a survey conducted during the fall, 1996 found that 65% of U.S. public schools has access to the Internet while 95% expected a connection by the year 2000.[1] Even though networked connectivity is occurring fairly rapidly, it is not happening too soon - especially for students. A USA Today poll conduct jointly with CNN and the National Science Foundation last spring,[2] talks about "techno-teens", rich or poor, male or female, embracing technology in all its forms. Eschewing TV and video games, they apply their time working on computers and the Internet. This study of 7th - 12th graders showed a proclivity towards using the technology when it was available.[2] Are students concerned about acquiring technology skills? The survey reported that 82% think they won't make a good living unless they have strong computer skills, and 65% feel schools should be teaching more in terms of computer education.[2] Any causal observation of how most kids interact with current technology combined with research results like the above, make it obvious what needs to be done to accomplish real structural change in the classroom. It may be obvious, but the task is neither easy nor inexpensive. Many teachers are still intimidated by technology and the facile way students use it. Technology change is happening at an incredibly rapid pace. Those school districts who take a conservative approach and who don't do their homework, end up taking delivery of hardware and software that either doesn't work well with the existing infrastructure or is already obsolete. Moving to a "technology rich" school environment is costly. One projection from Educational Testing Service is that it will take $15 billion to accomplish it.[3] Currently, the annual expenditure on technology is around $3 billion. A Preview of What Our New Network Does for Us In this article, we outline how our school is finding its way through this maze of technology issues and report on how we are integrating some new and powerful software tools with existing hardware to launch and manage our school's intranet. Even more important, of course, is what our students, faculty and staff, and parents gain from this new networked environment. This article provides some detailed examples as well as general observations. For example, all of our publications, from calendars to the school's newspaper Tiger Prints, are created and distributed this way. Teachers are building Web pages for personal and students' instructional use. Our special education students, from the efforts of an energized department staff, get an extra benefit. Using Web resources as a springboard, their learning experiences are being enhanced in very un-digital ways. Our social studies teachers led their students into first national political studies. Students then made their own way to local city government Web-based resources, popularizing them with all of the institution. Mainstreaming of the technology is seen in the rise of e-mail and use of FTP between people, and of course, more and more Web pages being created by everyone. Access from home is beginning to be noted by students, staff and parents. Videoconferencing is starting to be explored. And Web access to and from the community's public library is under review. Our Infrastructure We gained Internet access during the first semester of 1996. Our Internet gateway is established through a Sun SPARC server running I*Gear software. This software suite for K-12 includes components to filter both incoming and outgoing material, add and manage student and teacher accounts, and monitor system use -- all through an HTML format. …

Abstract: The regular occurrence of human rights abuses makes timely dissemination of information imperative. Much as the fax machine alerted those outside China's borders to its student pro‐democracy movement, the Internet has become a key instrument of communication to individuals and organizations engaged in more recent human rights activities. The many organizational, regional, and country Internet sites, networks, documents, alerts, documentation projects, and news services on human rights provide vital information to those interested or directly involved in protection of human rights. In this article, Carter and Davidson present a cross‐section of Internet sites, chiefly from the World Wide Web.

Abstract: INTRODUCTION The World Wide Web holds the promise of being the most powerful tool for accessing information in a wide range of subject areas. Because our nation places a high value on education, particularly in the areas of science, engineering and math, knowledge of Web-based resources in these areas is essential for people with disabilities. Researching this article has lead this author to two disturbing conclusions. There are very few specific special education resources in the area of science, engineering and math (SEM), and many of these resources are not offered in an accessible format. Many of the urls listed here are given as potential resources with comments as to why they were chosen. Plane Math http://www.planemath.com This site was created with help from NASA and was developed with special needs students in mind. A text version of the page is the first item that one encounters upon retrieving the page, which makes it accessible to all users. Math problems are designed around situations that might occur in dealing with airplanes. Frank Potter's Science Gems http://www-sci.lib.uci.edu/SEP/SEP.html If you visit this site, make sure you pack a lunch because it is packed with information in each of the areas covered in this article. The developer does a nice job of categorizing areas by subject and grade level. Although the site was not designed with access in mind, it is relatively user-friendly. Smart Elec Page--Calculators http://www.geocities.com/CapeCanaveral/5510/index.html Although this page is not user friendly, it deserves mention because there are a number of calculators here that show promise for use by special needs students. Blue Web'n Mathematics http://www.kn.pacbell.com/wired/bluewebn/fr_Mathematics.html This site would be difficult to access for users who have difficulty navigating frames, but there are a number of resources linked from the page that have real value. The KQED Center for Life Long Learning is one of these resources. MegaMath http://www.c3.lanl.gov/mega-math/menu.html This site deserves mention both for content and accessibility. The url given is for the textual menu version of the site. There is a rich graphical version as well. Some unusual lessons, such as the mathematics of knots, are featured. The Math Forum http://forum.swarthmore.edu/ The Math Forum is valuable for the resources in higher math. The site is organized around four basic components which helps the user navigate successfully and quickly. The four parts are: Student's Center, Teacher's Place, Research Division, and Parents and Citizens. The MIT Biology Hypertext Book http://esg-www.mit.edu:8001/esgbio/ While it takes some time to get where you are going here (which is the actual hypertext book), the route is fairly clear. …

Abstract: This paper describes an Internet search for the phrases radiation protection and health physics using major search engines and discusses the search procedure and the related problems. Depending on the search engine used, the number of hits ranged from 10,000 to only 17. The author presents some of the most relevant Web sites for radiation protection and health physics, and gives their URLs. As expected, these are mainly the sites of major national and international organizations. The author discusses a model for citation of WWW resources and refers to Internet links where this issue has been elaborated in more detail. Numerous links to various institutions and Web resources are given as well.

Abstract: The objective of this project is to create a compilation of educational resources in remote sensing accessible through the World-Wide Web (WWW). This compilation will be useful to anyone interested in learning about remote sensing. Educators might also find it useful as a place to locate useful resources for teaching courses in remote sensing. The remote sensing web resources were organized into several categories in the authors' web pages. These categories include: (1) Remote Sensing Missions, (2) Remote Sensing Applications, (3) Notes on Remote Sensing and (4) Interesting Images. The authors hope to provide a one-stop web page for accessing educational resources in remote sensing on the World Wide Web.

Abstract: This paper describes the Online Learning Academy (OLLA), a World Wide Web-based presence that supports the use of telecomputing in the classroom by: connecting teachers to each other and Internet educational resources; fostering the use of online resources and collaboration; encouraging and enabling the sharing of classroom experiences; and supporting and mentoring educators. Through a partnership among the application developers, educational technologists, curriculum specialists, and end users (teachers), the success of OLLA is based on the deployment of its three important components--appropriate content, continual professional development, and technology. The OLLA environment includes a personalized virtual classroom, "Kids Did This!" (collection of Web publications and student projects), resource center, mailing list, and personal journals. Units of study include selected and organized Web resources, presented around a theme. Initial results from pilot use with 20 elementary school teachers within the Department of Defense Educational Activity (DoDEA) schools during the 1996-1997 school year indicated OLLA's success. Teachers reported that OLLA: provided the means for communicating with other classrooms and teachers located at a distance; helped them to reach students who were difficult to reach using other approaches; is a great motivator for students and teachers alike; and is changing the way teachers think and teach.

Abstract: One of most serious problems plaguing the World Wide Web today is that of broken hypertext links, which are a major annoyance to browsing users and also a cause of tarnished reputation and possible loss of opportunity for information providers. The root of the problem lies in the current Web architecture's lack of support for referential integrity. This paper presents a model for the provision of referential integrity for Web resources which supports resource migration and tolerates site and communication failures. The approach is object-oriented, highly flexible, completely distributed, and does not require any global administration. An attractive feature of our design is the provision of a lightweight mechanism which provides referential integrity, and which may be customised on a per resource basis to provide increased fault-tolerance and performance. Our system follows an evolutionary approach, supporting parallel operation with the existing Web, allowing users to gain the additional benefits of referential integrity while allowing continued access through trusted software components.
