- Abstract
- This report introduces the Dublin Core Microformats (DCMF) project, a new way to use the DC element set within X/HTML. The DC microformats encode explicit semantic expressions in an X/HTML webpage, by using a specific list of terms for values of the attributes "rev" and "rel" for <a> and <link> elements, and "class" and "id" of other elements. Microformats can be easily processed by user agents and software, enabling a high level of interoperability. These characteristics are crucial for the growing number of social applications allowing users to participate in the Web 2.0 environment as information creators and consumers. This report reviews the origins of microformats; illustrates the coding of DC microformats using the Dublin Core Metadata Gen tool, and a Firefox extension for extraction and visualization; and discusses the benefits of creating Web services utilizing DC microformats.

- Abstract
- Google News and other newsbots have automated the process of news selection, providing Internet users with a virtually limitless array of news and public information dynamically culled from thousands of news organizations all over the world. In order to help users cope with the resultant overload of information, news leads are typically accompanied by three cues: (a) the name of the primary source from which the headline and lead were borrowed, (b) the time elapsed since the story broke, and (c) the number of related articles written about this story by other news organizations tracked by the newsbot. This article investigates the psychological significance of these cues by positing that the information scent transmitted by each cue triggers a distinct heuristic (mental shortcut) that tends to influence online users' perceptions of a given news item, with implications for their assessment of the item's relevance to their information needs and interests. A large 2 x 3 x 6 withinsubjects online experiment (N = 523) systematically varied two levels of the source credibility cue, three levels of the upload recency cue and six levels of the number-ofrelated-articles cue in an effort to investigate their effects upon perceived message credibility, newsworthiness, and likelihood of clicking on the news lead. Results showed evidence for source primacy effect, and some indication of a cue-cumulation effect when source credibility is low. Findings are discussed in the context of machine and bandwagon heuristics.

- "Für die meisten Surfer unsichtbar sind die so genannten Darknets. Dabei handelt es sich um Gruppen von Menschen und auch Unternehmen, die sich mit moderner Software im Internet völlig abkapseln und miteinander vernetzen, um Daten und Ideen auszutauschen. Die Mitglieder eines Darknet schützen sich mit Passwörtern und Codes. Wenn sie merken, dass es einen Verräter in den eigenen Reihen gibt, der diese. Sicherheitsschlüssel unbefugt weitergegeben hat, lösen sie sich kurzerhand auf. Dann wird ein neuer Geheim Treff geschaffen mit neuen digitalen Schutzmauern. Ein bekanntes, offiziell zugegebenes Darknet betreibt der amerikanische Pharmagigant GlaxoSmithKline. Seine Chemiker und Biologen arbeiten an einem neuen Mittel zum Abnehmen. Nicht nur alle, die intern an diesem Projekt arbeiten, sind mittels eines Darknets untereinander verbunden, sondern angeschlossen sind auch - weltweit - einige Forscher an Universitäten und Labors, so dass auch mit ihnen Informationen ausgetauscht werden können. Dieses Unternehmens-Darknet soll verhindern, dass die Konkurrenz von dem Geheimprojekt Wind bekommt. - Verschlüsselung zum Aufbau politischer Wehrdörfer - Auch Hewlett-Packard und Siemens sollen sich der Darknet Technologie zugewendet haben, um sehr sensitive Daten zu schützen. Ein cleverer 17-jähriger US-Schüler, der sich lediglich als "Trader X" zu erkennen gegeben hat; schuf sich unter der Bezeichnung Direct Connect (DC) sein eigenes Darknet. In dieser Digital-Burg, zu der vorwiegend Schüler und Studenten Zutritt haben, tauschen die Mitglieder frisch-fromm-fröhlich-frei kostenlos heruntergeladene DVDs und CDs aus. Sie scheren sich einen Teufel um die Drohungen und Klagen der US-Platten- oder Musikindustrie, mit der die Weitergabe von CDs unterbunden werden soll. Mit den technischen Möglichkeiten von Darknets hat Hollywood offensichtlich nie gerechnet. "So lange das Internet existiert, wird es auch einen solchen Austausch geben", verkündet Trader X" selbstbewusst. Die Darknets sind jedoch auch politische Wehrdörfer. Sie sind in Staaten aktiv, in denen es keine Presse- und Informationsfreiheit gibt. In China etwa sorgen die Darknet-Konstrukteure dafür, dass einer ausgewählten Gruppe von Personen der Zugang zu Nachrichten - etwa cnn.com - ermöglicht wird. Auch im Iran, in Nordkorea und Syrien sind Darknet-Aktivisten zu Gange. Für die Einrichtung von Darknets wird spezielle Software benötigt. Sie wird beispielsweise kostenlos durch Freenet und invisibleNET (www.invisiblenet.com) zur Verfügung gestellt. Auch AOL bot eine Zeitlang die kostenlos herunterzuladende Software namens "Waste". an. Sie soll besonders sicher sein, denn sie schützt ihre Klienten nicht nur durch Passwörter und Zugangscodes, sie verschlüsselt auch noch alle Daten, die von privaten Gruppen ausgetauscht werden. Solche Gruppen übrigens firmieren im Internet-Lexikon als Mesh. AOL hat das Angebot inzwischen aus dem Cyberspace wieder verbannt, existierende Kopien aber werden von PCFreaks weiter entwickelt und vertrieben."

- Abstract
- In order to transfer the Chinese Classified Thesaurus (CCT) into a machine-processable format and provide CCT-based Web services, a pilot study has been conducted in which a variety of selected CCT classes and mapped thesaurus entries are encoded with SKOS. OWL and RDFS are also used to encode the same contents for the purposes of feasibility and cost-benefit comparison. CCT is a collected effort led by the National Library of China. It is an integration of the national standards Chinese Library Classification (CLC) 4th edition and Chinese Thesaurus (CT). As a manually created mapping product, CCT provides for each of the classes the corresponding thesaurus terms, and vice versa. The coverage of CCT includes four major clusters: philosophy, social sciences and humanities, natural sciences and technologies, and general works. There are 22 main-classes, 52,992 sub-classes and divisions, 110,837 preferred thesaurus terms, 35,690 entry terms (non-preferred terms), and 59,738 pre-coordinated headings (Chinese Classified Thesaurus, 2005) Major challenges of encoding this large vocabulary comes from its integrated structure. CCT is a result of the combination of two structures (illustrated in Figure 1): a thesaurus that uses ISO-2788 standardized structure and a classification scheme that is basically enumerative, but provides some flexibility for several kinds of synthetic mechanisms Other challenges include the complex relationships caused by differences of granularities of two original schemes and their presentation with various levels of SKOS elements; as well as the diverse coordination of entries due to the use of auxiliary tables and pre-coordinated headings derived from combining classes, subdivisions, and thesaurus terms, which do not correspond to existing unique identifiers. The poster reports the progress, shares the sample SKOS entries, and summarizes problems identified during the SKOS encoding process. Although OWL Lite and OWL Full provide richer expressiveness, the cost-benefit issues and the final purposes of encoding CCT raise questions of using such approaches.
