PPP-QuestionParsing-Grammatical

Question Parsing module for the PPP using a grammatical approach.

Introduction

The purpose of this Question Parsing module is to transform questions into trees of triples, as described into our datamodel, which can be handled by backend modules.

For instance, we aim at producing the triple (Rwanda,president,?) from the question Who is the president of Rwanda?. The formal representation of this triple is:

{
    "type": "triple",
    "subject": {
        "value": "Rwanda",
        "type": "resource"
    },
    "predicate": {
        "value": "president",
        "type": "resource"
    },
    "object": {
        "type": "missing"
    }
}

See our website to learn more about the project and test our question answering tool.
