DataEx: Interactive Relationship Explorer of Freebase Knowledge Repository

摘要

In this paper we present DataEx, a HTML5 client-side Web application, which aims to make Web data more accessible by utilizing visualization as an useful approach to explore and navigate through large amounts of data and ultimately emphasize the relations between them. In order to provide several examples, we choose Freebase as a knowledge repository and its API in order to process data in real-time. In our case, the user interaction with such a large knowledge space is facilitated by different navigation and visualization techniques. Furthermore the main focus of the application lies on highlighting and analyzing the existing relationships between the data from the Freebase knowledge repository.
