    Abstract
    Social networks evolve over time with the addition and removal of nodes and links to survive and thrive in their environments. Previous studies have shown that the link-formation process in such networks is influenced by a set of facilitators. However, there have been few empirical evaluations to determine the important facilitators. In a research partnership with law enforcement agencies, we used dynamic social-network analysis methods to examine several plausible facilitators of co-offending relationships in a large-scale narcotics network consisting of individuals and vehicles. Multivariate Cox regression and a two-proportion z-test on cyclic and focal closures of the network showed that mutual acquaintance and vehicle affiliations were significant facilitators for the network under study. We also found that homophily with respect to age, race, and gender were not good predictors of future link formation in these networks. Moreover, we examined the social causes and policy implications for the significance and insignificance of various facilitators including common jails on future co-offending. These findings provide important insights into the link-formation processes and the resilience of social networks. In addition, they can be used to aid in the prediction of future links. The methods described can also help in understanding the driving forces behind the formation and evolution of social networks facilitated by mobile and Web technologies.

    Abstract
    In this research, we aim to identify factors that significantly affect the clickthrough of Web searchers. Our underlying goal is determine more efficient methods to optimize the clickthrough rate. We devise a clickthrough metric for measuring customer satisfaction of search engine results using the number of links visited, number of queries a user submits, and rank of clicked links. We use a neural network to detect the significant influence of searching characteristics on future user clickthrough. Our results show that high occurrences of query reformulation, lengthy searching duration, longer query length, and the higher ranking of prior clicked links correlate positively with future clickthrough. We provide recommendations for leveraging these findings for improving the performance of search engine retrieval and result ranking, along with implications for search engine marketing.

    Abstract
    This paper focuses on the need for knowledge organization (KO) tools, such as library classifications, thesauri and subject heading systems, to be fully disclosed and available in the open network environment. The authors look at the place and value of traditional library knowledge organization tools in relation to the technical environment and expectations of the Semantic Web. Future requirements in this context are explored, stressing the need for KO systems to support semantic interoperability. In order to be fully shareable KO tools need to be reframed and reshaped in terms of conceptual and data models. The authors suggest that some useful approaches to this already exist in methodological and technical developments within the fields of ontology modelling and lexicographic and terminological data interchange.

    Abstract
    The aim of this paper is to study the link relationships in the Nordic academic web space - comprised of 23 Finnish, 11 Danish and 28 Swedish academic web domains with the European one. Through social networks analysis we intend to detect sub-networks within the Nordic network, the position and role of the different university web domains and to understand the structural topology of this web space. Co-link analysis, with asymmetrical matrices and cosine measure, is used to identify thematic clusters. Results show that the Nordic network is a cohesive network, set up by three well-defined sub-networks and it rests on the Finnish and Swedish sub-networks. We conclude that the Danish network has less visibility than other Nordic countries. The Swedish one is the principal Nordic sub-network and the Finland network is a slightly isolated from Europe, with the exception of the University of Helsinki.

    Abstract
    This article analyzes the structure of the hyperlink network formed by the Web pages of Japanese public libraries and its relationship with the network formed by Inter-Library Loans (ILLs), the traditional system of cooperation among public libraries. Our results indicate that (a) the hyperlink network is effectively connected in the sense that each library is reachable from other libraries by clicking a few links and (b) the network has many groups of libraries that cooperate with each other. Most of the cliques consist of prefectural libraries or libraries in the same prefecture. The hyperlink network shows two of the same tendencies as the ILL network: (a) The connection among libraries that are geographically close to each other or in the same administrative unit is strong, and (b) prefectural libraries occupy the central position. There are differences between them, however, in terms of the amount of ILLs and cliques. We conclude that Japanese public libraries have formed a network on the Web that is strongly affected by traditional cooperation, but also incorporates some new types of cooperation from the perspective of cliques.

    Abstract
    This article argues that individual Web sites form hyperlink-affiliations with others for the purpose of strengthening their individual trust, expertness, and safety. It describes the hyperlink-affiliation network structure of Korea's top 152 Web sites. The data were obtained from their Web sites for October 2000. The results indicate that financial Web sites, such as credit card and stock Web sites, occupy the most central position in the network. A cluster analysis reveals that the structure of the hyperlink-affiliation network is influenced by the financial Web sites with which others are affiliated. These findings are discussed from the perspective of Web site credibility.

    Etliche Software-Anbieter preisen derzeit Webservices als eine zentrale Technologie, die viele Probleme der Informationstechnologie löst. Allen voran sehen die drei Software-Riesen IBM, Microsoft und Sun Webservices als wesentlichen Pfeiler ihrer neuen Produktstrategien, die sie mit klangvollen Namen wie Websphere_NET und Sun One (Sun Open Network Environment) schmücken. Und obwohl die drei zum Teil erbitterte Konkurrenzkämpfe austragen, wollen sie glauben machen, dass Webservices-basierende Software untereinander vollständig kompatibel ist. - Grundkonzept - Der Begriff Webservices ist zunächst einmal eher verwirrend als hilfreich, da er im Sinne von Webdiensten vollkommen unpräzise ist. Der Grundgedanke von Webservices ist an sich nicht vollkommen neu, sondern entspricht vielmehr der Idee der komponentenorientierten Software-Entwicklung. Während bei den üblichen Web-Anwendungen Daten für Menschen lesbar in einem Webbrowser dargestellt werden, ermöglichen die Webservices-Stan-dards den automatischen Datenaustausch zwischen verteilt verfügbaren Software-Bausteinen, ohne eine direkte Interaktion menschlicher Nutzer. Der wesentliche Unterschied zu den bereits seit einigen Jahren verfügbaren komponentenorientierten Entwicklungsstandards DCOM (Distributed Component Object Model) und Corba (Common Object Request Broker Architecture) ist die Unabhängigkeit von lokalen Netzwerken. Die Kommunikation zwischen den Komponenten über HTTP, prinzipiell aber auch über andere Protokolle, erfolgt durch XML-Dokumente. Derzeit versteht man unter Webservices Software-Module, die eine Schnittstelle nach dem SOAP-Standard aufweisen, per WSDL beschrieben sind und über UDDI gefunden werden können. Eine Übersicht über diese und einige weitere wichtige Webservices-Standards bietet die Tabelle auf S.28. Wesentliche technische Grundlage ist XML. Da XML als Metasprache nur beschreibt, wie man etwas beschreibt, wurde darauf aufbauend SOAP entwickelt. Es stellt das zentrale Portokoll zum Austausch von Nachrichten und Operationsaufrufen zwischen den einzelnen Software-Komponenten dar.

    Abstract
    Six years ago in this magazine, Tim Berners-Lee, James Hendler and Ora Lassila unveiled a nascent vision of the Semantic Web: a highly interconnected network of data that could be easily accessed and understood by any desktop or handheld machine. They painted a future of intelligent software agents that would head out on the World Wide Web and automatically book flights and hotels for our trips, update our medical records and give us a single, customized answer to a particular question without our having to search for information or pore through results. They also presented the young technologies that would make this vision come true: a common language for representing data that could be understood by all kinds of software agents; ontologies--sets of statements--that translate information from disparate databases into common terms; and rules that allow software agents to reason about the information described in those terms. The data format, ontologies and reasoning software would operate like one big application on the World Wide Web, analyzing all the raw data stored in online databases as well as all the data about the text, images, video and communications the Web contained. Like the Web itself, the Semantic Web would grow in a grassroots fashion, only this time aided by working groups within the World Wide Web Consortium, which helps to advance the global medium. Since then skeptics have said the Semantic Web would be too difficult for people to understand or exploit. Not so. The enabling technologies have come of age. A vibrant community of early adopters has agreed on standards that have steadily made the Semantic Web practical to use. Large companies have major projects under way that will greatly improve the efficiencies of in-house operations and of scientific research. Other firms are using the Semantic Web to enhance business-to-business interactions and to build the hidden data-processing structures, or back ends, behind new consumer services. And like an iceberg, the tip of this large body of work is emerging in direct consumer applications, too.

    Abstract
    The proposal is to use clusters, graphs and networks as models in order to analyse the Web structure. Clusters, graphs and networks provide knowledge representation and organization. Clusters were generated by co-site analysis. The sample is a set of academic Web sites from the countries belonging to the European Union. These clusters are here revisited from the point of view of graph theory and social network analysis. This is a quantitative and structural analysis. In fact, the Internet is a computer network that connects people and organizations. Thus we may consider it to be a social network. The set of Web academic sites represents an empirical social network, and is viewed as a virtual community. The network structural properties are here analysed applying together cluster analysis, graph theory and social network analysis. This is a work having taken place in the EICSTES project. EICSTES means European Indicators, Cyberspace, and the Science-Technology-Economy System. It is a research project supported by the Fifth Framework Program of R&D of the European Commission (IST-1999-20350)

    Abstract
    Issues of becoming an Internet user primarily in non-work contexts are discussed. The author reviews individual, social and economic factors motivating network use. Main findings of an empirical study based on the interviews of 23 Finns in 1997 are analysed. In addition, comparisons are made with the findings of the Consumer Research Project (1996-98), conducted in Finland. The main motivating factors leading to network use were the requirements of work and study; also making everyday transactions easier, for example by home banking, was seen as important. The network connections were also acquired for keeping in contact with others and for hobbies, whereas entertainment purposes were not valued.
