Topic distillation is the process of finding authoritative Web pages a comprehensive &quot;hubs&quot; which reciprocally endorse each other and are relevant to a given query. Hyperlink-based topic distillation has been traditionally applied to a macroscopic Web model where documents are nodes in a directed graph and hyperlinks are edges.Mas.M::[KP models miss va lua44 clues such aba4&apos;::M na viga::M paa els,as templa]M2&apos;0]K inclusions, whicha: embedded in HTML paLM using ma0KP taKP Consequently, results of ma:]6:1M2&apos; distillaKP] atillaKP have been deterioraKP] inqua:1 ya s Webpa0: a becoming more complex.

Map adaptation for users of mobile systems
Authors: Dan Chalmers, Morris Sloman, Naranker Dulay
Venue: WWW
Year: 2001

Display characteristics, network Quality of Service, and the user&apos;s current task all exhibit a wide range of variation when users interact with mobile and ubiquitous devices. It is desirable to enable applications to adapt to these variations. The user&apos;s experience in interacting with the application can be significantly enhanced by adapting the data presented. However, we find that naive degradation of data can quickly result in an unacceptable presentation. In this paper we present a means of describing compound documents and preferences according to the semantics of the data, and an algorithm for performing a selection amongst the offered data based on these descriptions. Our model of the user&apos;s preferences is more descriptive than most common specifications used for Webbased applications. These have been implemented for a map viewing application, along with application level network resource management. We present test results for adapting to network bandwidth and a download deadline. We show the technique is applicable over two orders of magnitude in bandwidth variation, and successful in meeting deadlines. By degrading the data presented in sympathy with the user&apos;s needs, the degradation has less impact on the user for any given benefit in download time than arbitrary selection.

Disconnected operation, in which a client accesses a service without relying on network connectivity, is crucial for improving availability, supporting mobility, and providing responsive performance. Because manyweb services are not cachable, disconnected access to web services may require mobile service code to execute in client caches. Unfortunately, (a) this code is untrusted, (b) this code mayhave nearly limitless resource demands due to prefetching, and (c) a large number of competing code modules must coexist. Thus, resource managementisakey problem both for preventing denial of service attacks and for providing good performance across many services. This paper addresses the feasibility of meeting the resource management needs of an environment where service code is shipped to clients, proxies, or content distribution intermediaries. It rst examines the requirements of such a system and then develops a resource-management strategy to meet these requirements by (a) providing isolation across services to prevent denial of service attacks, (b) automatically providing appropriate allocations to dierent services to provide good global performance, and (c) requiring no hand tuning across a wide range of system congurations and workloads. 1.

An admission control scheme for predictable server response time for web accesses
Authors: Xiangping Chen, Prasant Mohapatra, Huamin Chen
Venue: WWW
Year: 2001

The diversity in web object types and their resource requirements contributes to the unpredictability of web service provisioning. In this paper, an efficient admission control algorithm, PACERS, is proposed to provide different levels of services based on the server workload characteristics. Service quality is ensured by periodical allocation of system resources based on the estimation of request rate and service requirements of prioritized tasks. Admission of lower priority tasks is restricted during high load periods to prevent denial-of-services to high priority tasks. A double-queue structure is implemented to reduce the effects of estimation inaccuracy and to utilize the spare capacity of the server, thus increasing the system throughput. Response delays of the high priority tasks are bounded by the length of the prediction period. Theoretical analysis and experimental study show that the PACERS algorithm provides desirable throughput and bounded response delay to the prioritized tasks, without any significant impact on the aggregate throughput of the system under various workload.
Function-based object model towards website adaptation
Authors: Jinlin Chen, Baoyao Zhou, Jin Shi, HongJiang Zhang, Qiu Fengwu
Venue: WWW
Year: 2001

Content understanding is a crucial issue for website adaptation. In this paper we present a Function-based Object Model (FOM) that attempts to understand authors&apos; intention by identifying Object function instead of semantic understanding. Every Object in a website serves for certain functions (Basic and Specific Function) which reflect authors&apos; intention towards the purpose of an Object. Based on this consideration we have proposed the FOM model for website understanding. FOM includes two complementary parts: Basic FOM based on the basic functional properties of Object and Specific FOM based on the category of Object. An automatic approach to detect the functional properties and category of Object is presented for FOM generation. Two level adaptation rules (general rules and specific rules) based on FOM are combined for practical adaptation. A system for web content adaptation over Wireless Application Protocol (WAP) is developed as an application example of the proposed model. Experiments have shown satisfactory results and extensibility. Keywords Content Adaptation, Website Understanding, Content Function, HTML/WML Conversion 1.

Fine grained access control for SOAP E-services
Authors: Ernesto Damiani, Sabrina De Capitani di Vimercati, Stefano Paraboschi, Pierangela Samarati
Venue: WWW
Year: 2001

Lightweight protocols for remote service invocation via HTTP and XML, such as SOAP, are rapidly gaining acceptance among developers of Internet-based e-services, especially because of their rewall-traversal capabilities. However, no standard technique for access control security is currently defined for either HTTP or SOAP itself. Concerns have been raised about the possibility that different SOAP applications will deal with embedded security in different ways, leading to application-dependent security holes. In this paper, we propose an approach that relies on the XML structure of SOAP requests to support fine-grained authorizations at the level of individual XML elements and attributes that compose a SOAP call. The result is a simple, yet powerful and general, technique to enforce access restrictions to SOAP invocations.

A unified constraint model for XML
Authors: Wenfei Fan, Gabriel M. Kuper, Jérôme Siméon
Venue: WWW
Year: 2001

Integrity constraints are an essential part of modern schema denition languages. They are useful for semantic specication, update consistency control, query optimization, information preservation, etc. In this paper, we propose UCM, a model of integrity constraints for XML that is both simple and expressive. Because it relies on a single notion of keys and foreign keys, the UCM model is easy to use and makes formal reasoning possible. Becauseitreliesonapowerful type system, the UCM model is expressive, capturing in a single framework the constraints found in relational databases, objectoriented schemas and XML DTDs. We study the problem of consistency of UCM constraints, the interaction between constraints and subtyping, and algorithms for implementing these constraints.

Personal DJ, an architecture for personalised content delivery
Authors: Adam Field, Pieter H. Hartel, Wim Mooij
Venue: WWW
Year: 2001

Automated Personalised Audio is a relatively new concept, currently making its debut on the Web. Personalised audio relies on the existence of information about the music (music metadata) and information about the users (listener profiles). By gathering profile information, personalised audio systems attempt to select appropriate content for each user. This paper introduces the Personal DJ architecture for personalised audio. An evaluation of the concept is presented on the basis of data gathered from user tests. These tests were performed with a prototype developed from this architecture using simple mood based music metadata.

sTeam - Designing an integrative infrastructure for Web-based computer-supported cooperative learning
Authors: Thorsten Hampel, Reinhard Keil-Slawik
Venue: WWW
Year: 2001

Learning is a socially embedded design process. But most of today&apos;s hypermedia systems fail to properly support both the design-related and the social aspects of learning. Authoring and web-publishing systems aim to support the authors&apos; design process. Consequently, learners&apos; activities are confined to selecting and reading. Based on some fundamental reflections on the role of technology in learning processes, we conclude that top priority must be given to the construction of infrastructures that support cooperative learning processes if we are to properly harness technology&apos;s potential. We present a learner-centered -- wholly web-based -- approach for structuring information in teams (sTeam). The key concept in sTeam is virtual space. It draws together cooperation and communication, at the same time embodying the common external memory of a (virtual) learning group. The focus is not, then, on interactive systems for individual accessing of knowledge bases, but rather on the cooperative management and structuring of distributed knowledge bases.

Web-based personalization and management of interactive video
Authors: Rune Hjelsvold, Subu Vdaygiri, Yves Léauté
Venue: WWW
Year: 2001

This paper describes an application framework for providing and managing personalized, interactive video on the web. The application framework enables content providers and aggregators to stream personalized content to end-users. The server stores video and multimedia content that is structured and profiled. The content profile is matched against an end-user&apos;s interest profile to determine which parts of the video to include and what hotspots and hyperlinks to provide to the user. The server generates SMIL files that represent the personalized content and returns their unique URLs to the client when responding to end-user requests.

Combining RDF and XML schemas to enhance interoperability between metadata application profiles
Authors: Jane Hunter, Carl Lagoze
Venue: WWW
Year: 2001

The term "application profile" has recently become highly topical. Heery and Patel [1] define application profiles as metadata schemas which consist of metadata elements drawn from one or more namespaces, combined together by implementers and optimised for a particular local application. They state that the principal characteristics of an application profile are that: it may draw on one or more existing namespaces; does not introduce new metadata elements; it can specify permitted schemes and values; and it can refine standard metadata elements. Significant new initiatives such as TV-Anytime [2], MPEG-21 [3] and the Open Archives Initiative (OAI) [4] are demanding application profiles which combine elements from a number of different existing standardized metadata schemas whilst maintaining interoperability and satisfying their own specific requirements through refinements, extensions and additions. So far approaches to application profiles have been based on either RDF Schemas [5] or XML Schemas [6,7,8]. The SCHEMAS project [9] has adopted a purely RDF Schema approach. Justification for a pure XML Schema approach to application profiles is given in [10]. Despite high level assurances of unification from the W3C [11, 12], a purist and competitive attitude has prevailed amongst implementers. This has been because the demarcation of roles and the interface between these two disparate W3C Candidate Recommendations has been fuzzy; no low level details or implementations describing interface mechanisms have been provided; and implementers have been afraid of compromising interoperability. In this paper we describe a hybrid collaborative approach which combines the semantic knowledge of RDF Schemas with the explicit structural, cardinality and datatyping constraints provided by XML Schemas in a complementary manner. First we describe our view of how XML Schema and RDF Schema fit into the overall web metadata architecture. We then describe possible schema interface mechanisms. Finally using examples and mapping implementations based on XSLT and a metadata ontology, we demonstrate how interoperability between application profiles can be enhanced by using a dual schema approach.
A RTP to HTTP video gateway
Authors: Mathias Johanson
Venue: WWW
Year: 2001

Multicast audio and video conferences are today commonplace in certain parts of the Internet. The vast majority of Internet users, however, are not able to participate in these events because they either lack multicast network connectivity, are located behind firewalls, have insufficient network resources available or don&apos;t have access to the proper software tools. In many cases all of these restrictions apply. This paper presents an effort to extend the scope of multicast video conferencing by the development of an Internet video gateway that interconnects multicast networks with the World Wide Web. The overall design of the gateway software is outlined and a novel algorithm for rate control of the multicast video flows is described. Some performance tests that show the efficacy of the system in terms of resource utilisation and scalability are presented. Keywords Multimedia gateways, Multicast, Video, RTP, HTTP 1.
