A visual language for querying and updating graphs


SPARQL is not only a standard query language, but also a protocol for communicating with RDF databases.Graph DB stays compliant with the protocol specification and allows querying data with standard HTTP requests.Rosalba Giugno Universita' di Catania Dipartimento di Matematica e Informatica [email protected] Shasha Courant Institute of Mathematical Sciences Department of Computer Science New York University [email protected] What is Graph Grep?Compare Graph Blast Demo Download Graph Grep is a software package to search for a query graph in a database of graphs.You can see a complicated diagram showing only the top relationships, where each of them is a bundle of links between the individual instances of two classes.Each link is an RDF statement where the subject is an instance of one class, the object is an instance of another class, and the link is the predicate.Click on a node to see a menu for the following actions To explore the connectedness of a given class, double click the class circle or the Domain-Range Graph button from the side panel.



The components of Graph Grep are the following: Graph Grep manipulates heterogeneous graph collections and does not depend on a specific application. Many applications in industry, science, and engineering depend on efficient information retrieval methods from structured or semistructured databases.

Depending on the number of links between the instances of two classes, the bundle can be thicker or thinner and gets the colour of the class with more incoming links. In the example below, you can see the relationships between the classes of the News sample dataset provided in the distribution folder.

    In computing, a graph database is a database that uses graph structures for semantic queries with nodes, edges and properties to represent and store data. A key concept of the system is the graph or edge or relationship, which directly relates data items in the store. The relationships allow data in the store to be linked.…
