QA-GNN: Reasoning with Language Models and Knowledge Graphs for Question Answering
michiyasunaga/qagnn
•
•
NAACL 2021
The problem of answering questions using knowledge from pre-trained language models (LMs) and knowledge graphs (KGs) presents two challenges: given a QA context (question and answer choice), methods need to (i) identify relevant knowledge from large KGs, and (ii) perform joint reasoning over the QA context and KG.
Repurposing Entailment for Multi-Hop Question Answering Tasks

NAACL 2019
We introduce Multee, a general architecture that can effectively use entailment models for multi-hop QA tasks.
Multi-hop Question Answering via Reasoning Chains
soujanyarbhat/aNswER_multirc
•
•
Our analysis shows the properties of chains that are crucial for high performance: in particular, modeling extraction sequentially is important, as is dealing with each candidate sentence in a context-aware way.
MuSiQue: Multihop Questions via Single-hop Question Composition
Multihop reasoning remains an elusive goal as existing multihop benchmarks are known to be largely solvable via shortcuts.
End-to-End Beam Retrieval for Multi-Hop Question Answering
This approach models the multi-hop retrieval process in an end-to-end manner by jointly optimizing an encoder and two classification heads across all hops.
Commonsense for Generative Multi-Hop Question Answering Tasks
yicheng-w/CommonSenseMultiHopQA
•
•
EMNLP 2018
We instead focus on a more challenging multi-hop generative task (NarrativeQA), which requires the model to reason, gather, and synthesize disjoint pieces of information within the context to generate an answer.
HotpotQA: A Dataset for Diverse, Explainable Multi-hop Question Answering
hotpotqa/hotpot
•
•
EMNLP 2018
Existing question answering (QA) datasets fail to train QA systems to perform complex reasoning and provide explanations for answers.
Cognitive Graph for Multi-Hop Reading Comprehension at Scale
THUDM/CogQA
•
•
ACL 2019
We propose a new CogQA framework for multi-hop question answering in web-scale documents.
HybridQA: A Dataset of Multi-Hop Question Answering over Tabular and Textual Data

3) a hybrid model that combines heterogeneous information to find the answer.
Improving Multi-hop Question Answering over Knowledge Graphs using Knowledge Base Embeddings
malllabiisc/EmbedKGQA
•
•
ACL 2020
In a separate line of research, KG embedding methods have been proposed to reduce KG sparsity by performing missing link prediction.
