Semantic Web’s Linked Data Installation for Web at 25
All around the world people are celebrating the 25th anniversary of the invention of the Web. The Semantic Web Journal is participating in these festivities by launching its new Linked Data-powered digital installation.
The installation takes bibliographic data from WWW conferences between 1994 and 2014 and currently consists of two major components. The first component consists of a timeline where the top 100 keywords per WWW conference year are shown in different font sizes. The font size in the term cloud depicts the relative importance (frequency) of this keyword for that conference. While some obvious variations of the same keyword were merged (e.g., the singular and plural versions), other syntactic variations were kept deliberately. For instance, it is interesting to see how the term World Wide Web is increasingly replaced by WWW or simply the Web.
Moving away from a purely temporal perspective, the second component shows the spatial and spatiotemporal characteristics of the WWW bibliographic data. One can access the module by double-clicking on a term in the timeline. This will map the specific term-year tuple. It is possible to change the range and to add or remove certain keywords. The new range can be mapped, or the year-by-year change can be shown using an animation. It is worth mentioning that the list of mappable keywords includes all extracted keywords, not just the top 100 from the timeline.
