Zero-Shot Question Generation from Knowledge Graphs for Unseen Predicates and Entity Types

1 code implementation • NAACL 2018 • Hady Elsahar, Christophe Gravier, Frederique Laforest

We present a neural model for question generation from knowledge base triples in a "Zero-Shot" setup, that is generating questions for triples containing predicates, subject types or object types that were not seen at training time.

1 code implementation • 1 Nov 2017 • Pavlos Vougiouklis, Hady Elsahar, Lucie-Aimée Kaffee, Christoph Gravier, Frederique Laforest, Jonathon Hare, Elena Simperl

We explore the problem of generating natural language summaries for Semantic Web data.

High Recall Open IE for Relation Discovery

no code implementations • IJCNLP 2017 • Hady Elsahar, Christophe Gravier, Frederique Laforest

Relation Discovery discovers predicates (relation types) from a text corpus relying on the co-occurrence of two named entities in the same sentence.
