Mobile Location-Driven Associative Search in DBpedia with Tag Clouds

A primary contextual source for today’s context-sensitive mobile phone apps is the user’s location. The recent surge in the availability of open linked data can provide location-oriented semantic context, still wanting to be explored in innovative ways. In PediaCloud, the Android tool described here, we show how we can use the associative structure of the Semantic Web at a geographical location, visualize location information with tag clouds, and allow users to follow the associations of the Semantic Web enabled by the tag cloud, with the aim of enabling the users to construct an understanding of the “place” around them. The data we use are found through DBpedia, a project a project aimed to lift the information in WikiPedia into the Semantic Web.
