Data Graph Summary Samples

Below is a list of Data Graph Summary samples. For each of them, we list the SPARQL endpoint on which they were computed from. The availability of some endpoints, and may be down at any time.

To start using them, follow the Installation Instruction under the Configuring the Webapp section. Basically, you have to ingest a sample in a SPARQL endpoint, and edit the config.xml file of the SPARQLed as below:

<recommender>
    <backend>HTTP</backend>
    <backendArgs>http://path/to/endpoint-with-summary</backendArgs>
</recommender>

<proxy>
    <backend>HTTP</backend>
    <backendArgs>http://path/to/endpoint</backendArgs>
</proxy>

http://path/to/endpoint-with-summary is the endpoint where the summary sample is, and http://path/to/endpoint is the endpoint which contains the associated dataset.

• DBpedia3.7 sample (252 MB gzip compressed, NTriple format).

• Dataset endpoint: http://dbpedia.org/sparql

• Due to its size, it is advised to set a limit to the number of recommendations retrieved: recommender.limit = 1000.

• HCLS sample (62 KB gzip compressed, NTriple format)

• Dataset endpoint: http://hcls.sindicetech.com/sparql
