Introduction
Lab instructions
Semantic Web -aware tools and technologies are around….
Annotating flickr images:
-
Follow the instructions and generate RDF data for the image
Copy the source (
there is no need to understand it - this is messy XML syntax so we won't use it) and paste it in the
W3C RDF Validator - choose
Triples and Graph
option and click
Parse RDF
.
Analyze the triples (in table) and the graph. Copy it into the
report .
2 Common Vocabularies [10 minutes]
-
Answer the questions:
What is each vocabulary for?
What applications use them?
Browse thruogh more semantic vocabularies
here. Choose one vocabulary and describe it shortly in your report
.
3 FOAF [10 minutes]
-
Save your FOAF file. Put it in the report
.
Publish your file so that it can be referenced with
URL. Put the
URL into the report
-
Add more friends using their FOAF files. Visualize again.
4 Linked Open Data [20 minutes]
-
-
Analyze the
clickable LOD diagram, choose 5 datasets and in a few words describe them in the report (what information do they contain?)
Browse the following websites and get to know various Semantic Web tools and applications:
ConverterToRdf: which in your opinion are the most important? What Converter would you add (converting from what format)?
-
Sweet Tools: select one Annotator (tool for semantically annotating resources; you can simply put „Annotator” in search box) and describe it's capabilities.
-
Control questions
