Testing the S4 Services

The demo interface of the S4 Management console allows for testing the various text analytics services of S4 with sample data and for executing sample SPARQL queries against DBpedia, GeoNames and Freebase datasets:

Testing the Text Analytics Services

You can copy & paste some sample data (news article, a tweet, or a biomedical document), select the proper text analytics service and see the results of the processing. For example, copying & pasting text from this sample news article will produce the following results, with various persons, organisations, locations, and relations automatically identified from the text content:

Testing the Linked Open Dataset Access

For testing the Linked Open Data access via S4 the demo interface provides a set of sample queries. When you select a query, its SPARQL source will be shown and then you can execute it and view the resulting triples.

This sample query uses data from DBpedia and performs a lookup for airports within 50 miles radius of London:

Finally, the results of the query are visualised:

The Preferences section allows for communication and notification preferences to be specified

Monthly Usage Report

The monthly usage report is optional, and it provides a summary of the usage of the text analytics and LOD services for the most recent reporting period:

API Key Management

The API Key Management section allows for API keys to be created, deleted, disabled/enabled.

Note: You must store the private part of the API key at a secure location. Otherwise, if you lose your API key, you will need to generate a new one.


The Reports section provides access to usage reports from up to 6 months back in time. The monthly reports can also be sent via email, if this setting is enabled from the Preferences section.

REST Services

The REST Services section provides details about the service endpoints and links to the relevant documentation at


The Database section provides a management UI for the fully managed RDF database (DBaaS) on S4. The functionality includes: creating/deleting a database, specifying various database parameters, backup & restore, full data export

When creating a database the user has to specify the database name, the type of database (Micro, XS, S, M or L), the requested IO performance, as well as whether the database's SPARQL endpoint should allow public read-only access (without the need for API key pairs)

When creating a repository user has to specify the repository id, the repository title(description), ruleset, base-URL , use of predicate indices and proportion for cache distribution between repositories.
