Skelett mit Sonnenbrille Hirsch sitzt in einem grell erleuchteten Konferenzraum. In der rechten Ecke steht ein Skelett, dem jemand eine Sonnenbrille aufgeklemmt hat. In der Hand hält Hirsch ein Modellgehirn, auf dem er im Rhythmus seines Sprachflusses mit den Fingern trommelt. Obwohl im Verlauf der nächsten Stunden erschreckend verwickelte Netzdiagramme zum Einsatz kommen, hält Hirsch sich an die Suggestivkraft des Bildes. Er sagt: "Das Primärerlebnis der Maschine ist bei Google das eines Jägers. Sie pirscht sich an eine Internetseite heran." Man denkt: "Genauso fühlt es sich an: Suchbegriff eingeben, 'enter' drücken, Website schießen!", schon kommt die Komplementärmetapher geschmeidig aus dem Köcher: Im Gegensatz zum Google-Jäger, sagt Hirsch, sei der eyePlorer ein Sammler, der stöbere, organisiere und dann von allem nasche. Hier werden Informationen, auf die handelsübliche Suchmaschinen nur verweisen, kulinarisch aufbereitet und zu Schwerpunkten verknüpft. Im Gegensatz zu ihren Vorgängern ist die Maschine ansatzweise intelligent. Sie findet im Laufe einer Sitzung heraus, worum es dem Benutzer geht, versteht den Zusammenhang von Suche und Inhalt und ist deshalb in der Lage, Empfehlungen auszusprechen.

Abstract

With the terrific growth of data volume and data being produced every second on millions of devices across the globe, there is a desperate need to manage the unstructured data available on web pages efficiently. Semantic Web or also known as Web of Trust structures the scattered data on the Internet according to the needs of the user. It is an extension of the World Wide Web (WWW) which focuses on manipulating web data on behalf of Humans. Due to the ability of the Semantic Web to integrate data from disparate sources and hence makes it more user-friendly, it is an emerging trend. Tim Berners-Lee first introduced the term Semantic Web and since then it has come a long way to become a more intelligent and intuitive web. Data Visualization plays an essential role in explaining complex concepts in a universal manner through pictorial representation, and the Semantic Web helps in broadening the potential of Data Visualization and thus making it an appropriate combination. The objective of this chapter is to provide fundamental insights concerning the semantic web technologies and in addition to that it also elucidates the issues as well as the solutions regarding the semantic web. The purpose of this chapter is to highlight the semantic web architecture in detail while also comparing it with the traditional search system. It classifies the semantic web architecture into three major pillars i.e. RDF, Ontology, and XML. Moreover, it describes different semantic web tools used in the framework and technology. It attempts to illustrate different approaches of the semantic web search engines. Besides stating numerous challenges faced by the semantic web it also illustrates the solutions.

As the team describe in a paper posted (http://arxiv.org/abs/1605.04951) on arXiv, they found that figures did indeed matter-but not all in the same way. An average paper in PubMed Central has about one diagram for every three pages and gets 1.67 citations. Papers with more diagrams per page and, to a lesser extent, plots per page tended to be more influential (on average, a paper accrued two more citations for every extra diagram per page, and one more for every extra plot per page). By contrast, including photographs and equations seemed to decrease the chances of a paper being cited by others. That agrees with a study from 2012, whose authors counted (by hand) the number of mathematical expressions in over 600 biology papers and found that each additional equation per page reduced the number of citations a paper received by 22%. This does not mean that researchers should rush to include more diagrams in their next paper. Dr Howe has not shown what is behind the effect, which may merely be one of correlation, rather than causation. It could, for example, be that papers with lots of diagrams tend to be those that illustrate new concepts, and thus start a whole new field of inquiry. Such papers will certainly be cited a lot. On the other hand, the presence of equations really might reduce citations. Biologists (as are most of those who write and read the papers in PubMed Central) are notoriously mathsaverse. If that is the case, looking in a physics archive would probably produce a different result.
