3. But just to have it a bit more clear….
• Open it with your favourite ontology editor 

4. Lets try to model some Twitter data with SIOC
• Lets remind which sort of data Twitter give us…
– Information about the post
– Information about the user

• Lets remind which sort of data Twitter give us…
– Entities, including hashtags, user mentions and urls

This Gists contains three main files:
– SIOCTWitterParser.java: contains the code that you need to parse
Twitter data and transform it into SIOC format
– pom.xml: contains the dependencies. If you prefer not to use a maven
project, just go to jena and JSON-Liband download the corresponding
libraries
– siocTwitterParser.properties: this is the properties file that you need to
set up, including
• siocOntologyFolder. This is the local folder in your computer where you
store the SIOC ontology
• jsonInputFile. This is an example of a Twitter JSON file. Note that you
can can directly connect, download Twitter data and transform it! :)
• rdfOutputFile. This is the output file containing SIOC transformed Twitter
data
