Templator

Templator is a module for dependency-driven SPARQL template generation from natural language. It is part of the OKBQA question answering framework and currently works for English and Korean.

REST service

The module is running on http://110.45.246.131:1555/templategeneration/templator. The repository contains two examples files (src/test/test_en.json and src/test/test_ko.json) you can use for testing:

curl -i -H "Content-Type: application/json" -X POST -d @test_ko.json http://110.45.246.131:1555/templategeneration/templator

Example

Input:

{ "string": "어떤 강이 군산을 흐르는가?", "language":"ko" }

Output (for expansionDepth=0):

[{"score":"1.0","slots":[{"p":"is","s":"v5","o":"http:\/\/lodqa.org\/vocabulary\/sort_of"},{"p":"is","s":"v4","o":"rdf:Resource|rdfs:Literal"},{"p":"verbalization","s":"v4","o":"군산을"},{"p":"is","s":"v3","o":"rdf:Property"},{"p":"verbalization","s":"v3","o":"흐르는가"},{"p":"is","s":"v1","o":"rdf:Class"},{"p":"verbalization","s":"v1","o":"강이"}],"query":"SELECT ?v2 WHERE { ?v2 ?v3 ?v4 ; ?v5 ?v1 . } "}]

Which expresses the following SPARQL template:

SELECT  ?v2
WHERE
  { ?v2  ?v5  ?v1 ;
         ?v3  ?v4 .
  }

 v5 - (<http://lodqa.org/vocabulary/sort_of>)
 v1 강이 (rdf:Class)
 v3 흐르는가 (rdf:Property)
 v4 군산을 (rdf:Resource|rdfs:Literal)

Score: 1.0
