Question Answering systems are generally modelled as a pipeline consisting of a sequence of steps. In such a pipeline, Entity Linking (EL) is often the first step. Several EL models first perform span detection and then entity disambiguation. In such models errors from the span detection phase cascade to later steps and result in a drop of overall accuracy. Moreover, lack of gold entity spans in training data is a limiting factor for span detector training. Hence the movement towards end-to-end…

Zero-shot Entity Linking with Less Data

This paper proposes a neuro-symbolic, multi-task learning approach that achieves superior performance on ZEL task with significantly less training data and shows that this approach achieves significantly higher performance than SOTA models when they are trained with just 0.01% or 1% of the original training data.

Tree-KGQA: An Unsupervised Approach for Question Answering Over Knowledge Graphs

The comprehensive evaluations demonstrate that the unsupervised KGQA approach outperforms other supervised state-of-the-art methods on the WebQSP-WD test set (1.4% increase in F1 score) - without training on the target dataset.

Neural Entity Linking: A Survey of Models based on Deep Learning

This work distills a generic architecture of a neural EL system and discusses its components, such as candidate generation, mention-context encoding, and entity ranking, summarizing prominent methods for each of them.

Survey on English Entity Linking on Wikidata

This survey reveals that current Wikidata-specific Entity Linking datasets do not differ in their annotation scheme from schemes for other knowledge graphs like DBpedia, and shows that the potential for multilingual and time-dependent datasets, naturally suited forWikidata, is not lifted.

Survey on English Entity Linking on Wikidata: Datasets and approaches

This survey reveals that current Wikidata-specific Entity Linking datasets do not differ in their annotation scheme from schemes for other knowledge graphs like DBpedia, and shows that the potential for multilingual and time-dependent datasets, naturally suited forWikidata, is not lifted.

On the Capabilities of Pointer Networks for Deep Deductive Reasoning

This paper applies neural pointer networks for conducting reasoning over symbolic knowledge bases to explore the benefits and limitations of encoder-decoder architectures in general and pointer networks in particular for developing accurate, generalizable and robust neuro-symbolic reasoners.

Re-ranking for joint named-entity recognition and linking

A joint model for NER and EL is presented, called NEREL, that takes a large set of candidate mentions from typical NER systems and a largeSet of candidate entity links from EL systems, and ranks the candidate mention-entity pairs together to make joint predictions.

EARL: Joint Entity and Relation Linking for Question Answering over Knowledge Graphs

This paper proposes a framework called EARL, which performs entity linking and relation linking as a joint task, and implements two different solution strategies, which significantly outperform the current state-of-the-art approaches for entity and relations linking.

Improving Neural Entity Disambiguation with Graph Embeddings

This work proposes a method that uses graph embeddings for integrating structured information from the knowledge base with unstructured information from text-based representations and confirms that graph embedDings trained on a graph of hyperlinks between Wikipedia articles improve the performances of simple feed-forward neural ED model and a state-of-the-art neural ED system.

Query-Driven On-The-Fly Knowledge Base Construction

This work proposes a novel approach to build on-the-fly knowledge bases in a query-driven manner, based on a semantic-graph representation of sentences, by which three key IE tasks are performed, namely named-entity disambiguation, co-reference resolution and relation extraction, in a light-weight and integrated manner.
