- Abstract
- Mit der Suchmaschine Google, den Satelitenkarten auf Google Maps, mit der Volltextsuche in Google Books, mit dem Bildprogramm Picasa, dem Mail-Programm Google Mail, Google Docs und vielen weiteren Services entwickelt sich die Firma von Larry Page und Sergej Brin zur unkontrollierten Weltmacht im Internet: Immer mehr Firmen entwickeln Dienste und Geräte, die ausschließlich auf Google abgestimmt sind. Praktisch zählt nur mehr das Wissen, das man über Google findet. Diese Monopolstellung ist für eine Wissensgesellschaft gefährlich. Sie erleichtert die politische Zensur, wie sie bei Google in China stattfindet, und sie erleichtert das Ausspionieren unserer Privatsphäre. Denn jede Suchanfrage bleibt bei Google über Jahre gespeichert: In den USA wird derzeit eine Frau des Mordes an ihrem Mann verdächtigt, weil sie einmal in Google den Suchbegriff "murder" eingetippt hat.

- Abstract
- Eleven middle school children constructed hierarchical maps for two science categories selected from two Web directories, Yahooligans! and KidsClick! For each category, children constructed a pair of maps: one without links and one with links. Forty-tour maps were analyzed to identify similarities and differences. The structures of the maps were compared to the structures employed by the directories. Children were able to construct hierarchical maps and articulate the relationships among the concepts. At the global level (whole map), children's maps were not alike and did not match the structures of the Web directories. At the local levels (superordinate and subordinate), however, children shared similarities in the conceptual configurations, especially for the concrete concepts. For these concepts, substantial overlap was found between the children's structures and those employed in the directories. For the abstract concepts the configurations were diverse and did not match those in the directories. The findings of this study have impl!cations for design of systems that are more supportive of children's conceptual structures.

- The View From Above Browsing for a particular piece on information on the Web can often feel like being stuck in an unfamiliar part of town walking around at street level looking for a particular store. You know the store is around there somewhere, but your viewpoint at ground level is constrained. What you really want is to get above the streets, hovering half a mile or so up in the air, to see the whole neighbourhood. This kind of birds-eye view function has been memorably described by David D. Clark, Senior Research Scientist at MIT's Laboratory for Computer Science and the Chairman of the Invisible Worlds Protocol Advisory Board, as the missing "up button" on the browser [3] . ET-Map is a nice example of a prototype for Clark's "up-button" view of an information space. The goal of information maps, like ET-Map, is to provide the browser with a sense of the lie of the information landscape, what is where, the location of clusters and hotspots, what is related to what. Ideally, this 'big-picture' all-in-one visual summary needs to fit on a single standard computer screen. ET-Map is one of my favourite examples, but there are many other interesting information maps being developed by other researchers and companies (see inset at the bottom of this page). How does ET-Map work? Here is a sequence of screenshots of a typical browsing session with ET-Map, which ends with access to Web pages on jazz musician Miles Davis. You can also tryout ET-Map for yourself, using a fully working demo on the AI Lab's website [4] . We begin with the top-level map showing forty odd broad entertainment 'subject regions' represented by regularly shaped tiles. Each tile is a visual summary of a group of Web pages with similar content. These tiles are shaded different colours to differentiate them, while labels identify the subject of the tile and the number in brackets telling you how many individual Web page links it contains. ET-Map uses two important, but common-sense, spatial concepts in its organisation and representation of the Web. Firstly, the 'subject regions' size is directly related to the number of Web pages in that category. For example, the 'MUSIC' subject area contains over 11,000 pages and so has a much larger area than the neighbouring area of 'LIVE' which only has 4,300 odd pages. This is intuitively meaningful, as the largest tiles are visually more prominent on the map and are likely to be more significant as they contain the most links. In addition, a second spatial concept, that of neighbourhood proximity, is applied so 'subject regions' closely related in term of content are plotted close to each other on the map. For example, 'FILM' and 'YEAR'S OSCARS', at the bottom left, are neighbours in both semantic and spatial space. This make senses as many things in the real-world are ordered in this way, with things that are alike being spatially close together (e.g. layout of goods in a store, or books in a library). Importantly, ET-Map is also a multi-layer map, with sub-maps showing greater informational resolution through a finer degree of categorization. So for any subject region that contains more than two hundred Web pages, a second-level map, with more detailed categories is generated. This subdivision of information space is repeated down the hierarchy as far as necessary. In the example, the user selected the 'MUSIC' subject region which, not surprisingly, contained many thousands of pages. A second-level map with numerous different music categories is then presented to the user. Delving deeper, the user wants to learn more about jazz music, so clicking on the 'JAZZ' tile leads to a third-level map, a fine-grained map of jazz related Web pages. Finally, selecting the 'MILES DAVIS' subject region leads to more a conventional looking ranking of pages from which the user selects one to download.
Information Maps There are many other fascinating examples that employ two dimensional interactive maps to provide a 'birds-eye' view of information. They use various underlying techniques of textual analysis and clustering to turn the mass of information into a useful summary map (see "Mining in Textual Mountains" in Mappa.Mundi Magazine). In terms of visual representations they can be divided into two groups, those that generate smooth surfaces and those that produce regular, tiled maps. Unfortunately, we don't have space to examine them in detail, but they are well worth spending some time exploring. I will be covering some of them in future columns.

- Abstract
- The desalination industry involves the desalting of sea or brackish water and achieves the purpose of increasing the worls's effective water supply. There are approximately 4.000 desalination Web sites. The six major Internet search engines were used to determine, according to each of the six, the top twenty sites for desalination. Each site was visited and the 120 gross returns were pared down to the final ten - the 'Top Ten'. The Top Ten were then analyzed to determine what it was that made the sites useful and informative. The major attributes were: a) currency (up-to-date); b) search site capability; c) access to articles on desalination; d) newsletters; e) databases; f) product information; g) online conferencing; h) valuable links to other sites; l) communication links; j) site maps; and k) case studies. Reasons for having a Web site and the current status and prospects for Internet commerce are discussed

- Diese "soziale" Ebene legt Google künftig über quasi alle seine Produkte. So zeigen die neu gestalteten Google Maps einem Kunstliebhaber einen Stadtplan mit allen Galerien und Museen, während einem Shopaholic dagegen bevorzugt Boutiquen und Kaufhäuser auf denselben Karten ausschnitt gezeichnet werden. Außerdem werden Informationen über Unfälle auf den Straßen direkt in Google Maps eingebunden . Zudem wurde ein neuer Streaming-Musikdienst vorgestellt, bei dem die Songs direkt aus dem Netz abgespielt werden. Das Abo-Angebot mit dem Namen Google Play Music All Access ist zunächst in den USA verfügbar. Für die Google-Anwender heißt dies zunächst, dass die Dienste des Internet-Giganten im Zweifelsfall noch praktischer werden als sie es heute ohnehin schon sind. Gleichzeitig müssen sich die User aber auch vor Augen halten, wie sehr sie sich vom Wohl und Wehe eines einzelnen Un- ternehmens abhängig machen und welche Datenschätze sie diesem Konzern anvertrauen. Diese Befürchtungen dürften auch der Grund dafür gewesen sein, dass Google-Chef Larry Page sich zum Ende der Keynote mit der grundsätzlichen Frage beschäftigte, welche Ängste neue Technologien wie die Cyberbrille Google Glass bei Menschen auslösen können. Page räumte ein, dass die rasanten Veränderungsprozesse Menschen in eine unkom- fortable Lage versetzten. "In der Technologie(entwicklung) sollten wir einige sichere Plätze haben, an denen wir neue Dinge ausprobieren und herausfinden können, wie der Effekt auf die Gesellschaft und auf die Menschen ist. Dazu sollten wir nicht gezwungen sein, diese Neuheiten auf der ganzen Welt ausrollen." "
