The TALP participation at ERD 2014

2014 Proceedings of the first international workshop on Entity recognition & disambiguation - ERD '14  
To this end, we presented our system taking advantage of a topic modeling approach to rank candidates of each entity mentions occurring in the query text.  ...  The objective of this evaluation track is to recognize mentions of entities in a given short text, disambiguate them and map them to the entities in a given collection of knowledge base.  ...  In the short text track, given a query text for each query, the ERD system should use all available context to select the correct KB candidate of each entity surface form occurring in the query text.  ...

Entity Disambiguation with Web Links

Andrew Chisholm, Ben Hachey
2015 Transactions of the Association for Computational Linguistics  
We explore whether web links can replace a curated encyclopaedia, obtaining entity prior, name, context, and coherence models from a corpus of web pages with links to Wikipedia.  ...  Combining web link and Wikipedia models produces the best-known disambiguation accuracy of 88.7 on standard newswire test data.  ...  Using deep neural networks, they learn entity representations based on similarity between link contexts and article text in Wikipedia.  ...

Natural Language Interfaces to Data

Abdul Quamar, Vasilis Efthymiou, Chuan Lei, Fatma Özcan
2022 Foundations and Trends in Databases  
There are three main challenges in natural language querying: (1) identifying the entities involved in the user utterance, (2) connecting the different entities in a meaningful way over the underlying  ...  There are two main approaches in the literature for interpreting a user's natural language query. Rule-based systems make use of semantic indices, ontologies, and knowledge  ...  With the advances in deep learning-based language models, there have been many text-to-SQL approaches that try to interpret the query holistically using deep learning models.  ...

Robust and Collective Entity Disambiguation through Semantic Embeddings

Stefan Zwicklbauer, Christin Seifert, Michael Granitzer
2016 Proceedings of the 39th International ACM SIGIR conference on Research and Development in Information Retrieval - SIGIR '16  
We propose a new collective, graph-based disambiguation algorithm utilizing semantic entity and document embeddings for robust entity disambiguation.  ...  Our approach is also able to abstain if no appropriate entity can be found for a specific surface form.  ...  Semantic embeddings have also been used for entity disambiguation. In 2013, He et al. [13] proposed an entity disambiguation model, based on Deep Neural Networks.  ...

A Recurrent Model for Collective Entity Linking with Adaptive Features

Xiaoling Zhou, Yukai Miao, Wei Wang, Jianbin Qin
2020 PROCEEDINGS OF THE THIRTIETH AAAI CONFERENCE ON ARTIFICIAL INTELLIGENCE AND THE TWENTY-EIGHTH INNOVATIVE APPLICATIONS OF ARTIFICIAL INTELLIGENCE CONFERENCE  
Traditional machine learning based methods for NED were outperformed and made obsolete by the state-of-the-art deep learning based models.  ...  We propose novel adaptive features that focus on extracting discriminative features to better model similarities between candidate entities and the mention's context.  ...  The Titan V used for this research was donated by the NVIDIA Corporation.  ...

A Sequence Learning Method for Domain-Specific Entity Linking

Emrah Inan, Oguz Dikenelli
2018 Proceedings of the Seventh Named Entities Workshop  
Second, we resolve more ambiguous pairs using bidirectional Long Short-Term Memory and CRF models for the entity disambiguation.  ...  Also, semantic embeddings only indicate relatedness between entity pairs without considering sequences. In this paper, we address these problems by introducing a two-fold neural model.  ...  Most recent deep learning approaches have been presented as a way to support better generalization for the similarity measurement of context, mention and entity (Sun et al., 2015) .  ...

Scalable Disambiguation System Capturing Individualities of Mentions [chapter]

Tiep Mai, Bichen Shi, Patrick K. Nicholson, Deepak Ajwani, Alessandra Sala
2017 Lecture Notes in Computer Science  
In this paper, we propose a new system that learns specialized features and models for disambiguating each ambiguous phrase in the English language.  ...  Entity disambiguation, or mapping a phrase to its canonical representation in a knowledge base, is a fundamental step in many natural language processing applications.  ...  However, due to the utilization of pairwise wordentity, entity-entity interactions or even combinatorial interactions, many joint disambiguation approaches suffer from slow query time.  ...

Leveraging Deep Neural Networks and Knowledge Graphs for Entity Disambiguation [article]

Hongzhao Huang and Larry Heck and Heng Ji
2015 arXiv   pre-print
This paper presents a novel deep semantic relatedness model (DSRM) based on deep neural networks (DNN) and semantic knowledge graphs (KGs) to measure entity semantic relatedness for topical coherence modeling  ...  Modeling topical coherence is crucial for this task based on the assumption that information from the same semantic context tends to belong to the same topic.  ...  Then we apply the approach to model topical coherence for entity disambiguation, as opposed to Web search.  ...
