RDF Browser for Data Discovery and Visual Query Building

Visual servoing or image-based camera control consists in specifying a task (mainly positioning or target tracking tasks) as the regulation in the image of a set of visual features

In our evaluation, we show that SAFE enables granular graph-level access control over distributed clinical RDF data cubes and efficiently reduces the query execution time when

This analysis shown in Figure 6 shows that participants found data source and triple pattern(s) related information helpful for understanding the query result derivation, but have

Below we outline a path we started from devising an RDF counterpart to relational (data warehouse) relational queries, formalizing RDF analytical (aggregate) queries (Section 3.1),

Figure 1 provides a screenshot of the interface for querying Wikidata, where we can see three components: a search panel (left pane), a visual query editor (center pane), a node

There are two options of linked node introduction into a query: either by introducing both nodes (typically, classes) into the query pane and then connecting the nodes by a link

– Query writing for the expert, exploiting the capacity of the underlying conceptual models and gathering best practices from similar systems, – Discovery of metadata

For in- stance, the configuration (2, 1, {{OPTIONAL, FILTER}, {UNION}}, 10) makes QED construct a test suite containing 10 test cases with queries that contain both OPTIONAL and
