Query generation

A query generation module is responsible for generating SPARQL queries based on the outputs of preceding two modules, a template generation and a disambiguation modules.

Input

Example query: How many students does the Free University in Amsterdam have?

  • one pseudo query (from the output of template generation)

  • one set of disambiguation (from the output of disambiguation)

{

"template":{

"query": "SELECT ?v2 WHERE { ?v1 ?p1 ?v2 . }",

"slots":[

{"s":"v1", "p":"a", "o":"owl:NamedIndividual"},

{"s":"v1", "p":"verbalization", "o":"owl:NamedIndividual"},

{"s" "var": "v1", "form": "Free University in Amsterdam", "annotation": },

{"var": "p1", "form": "students", "annotation": "owl:DatatypeProperty" }

],

"score": 0.5

},
