Task1: Rhizomik viz service
1. Use the lemon pattern service to generate RDF
http://services.lider-project.eu/lemonpatterns
2. Use Rhizomik viz service to visualize your RDF

Task2: Use Lemon Assistant
• Using Lemon Assistant
– Create some lemon pattern
– Copy the lemon pattern code in the lemon pattern
service
– Generate code
– Visualize it with Rhizomik

Task3: Become a master of the
linguistic LOD universe!!
• Using Leire
– Store your triples in a Fuseki triple store
• There is a running Fuseki triple store for each group
– If you are group X, use
» User interface
• http://lider2.dia.fi.upm.es:304X/sparql.tpl
» SPARQL EP
• http://lider2.dia.fi.upm.es:304X/ds/sparql

The last slide
• In the lexicalization process
– Forget RDF with
• Lemon Patterns
– Lemon Assistant
• Enjoy RDF with RDF visualizers (like Rhizomik)
– Forget SPARQL with
• Leire
• Enjoy the exercises 
P.D.: collaborators are welcome!
