SynSetExpan: An Iterative Framework for Joint Entity Set Expansion and Synonym Discovery [article]

Jiaming Shen and Wenda Qiu and Jingbo Shang and Michelle Vanni and Xiang Ren and Jiawei Han
2020 arXiv   pre-print
In this work, we hypothesize that these two tasks are tightly coupled because two synonymous entities tend to have similar likelihoods of belonging to various semantic classes.  ...  Meanwhile, the set expansion model, being able to determine whether an entity belongs to a semantic class, can generate pseudo training data to fine-tune the synonym discovery model towards better accuracy  ...  Finally, we rank all entities in the vocabulary based on their predicted probabilities. Two Models' Mutual Enhancements Set Expansion Enhanced Synonym Discovery.  ...

Enhancing Knowledge Graph Embedding with Probabilistic Negative Sampling

Vibhor Kanojia, Hideyuki Maeda, Riku Togashi, Sumio Fujita
2017 Proceedings of the 26th International Conference on World Wide Web Companion - WWW '17 Companion  
Link Prediction using Knowledge graph embedding projects symbolic entities and relations into low dimensional vector space, thereby learning the semantic relations between entities.  ...  The enhancements enable the model to smartly generate corrupted triplets during negative sampling, which significantly improves the training time and performance of TransR.  ...  We used two measures as our evaluation metric: (1) Mean Rank of correct entities; and (2) proportion of correct entities in top-10 ranked entities (Hits@10). Ranking is decided by score function fr.  ...

Toward a Deep Neural Approach for Knowledge-Based IR [article]

Gia-Hung Nguyen, Lynda Tamine, Laure Soulier, Nathalie Bricon-Souf
2016 arXiv   pre-print
In this paper, we review the main approaches of neural-based document ranking as well as those approaches for latent representation of entities and relations via KBs.  ...  More particularly, this paper advocates that KBs can be used either to support enhanced latent representations of queries and documents based on both distributional and relational semantics or to serve  ...  their symbolic semantics in the KB (e.g., the embedding of concepts extracted in common in both entities).  ...

Entity-Based Stochastic Analysis Of Search Results For Query Expansion And Results Re-Ranking

Pavlos Fafalios, Yannis Tzitzikas
2015 Zenodo  
In this paper we introduce a method that exploits entities from the emerging Web of Data for enhancing various Information Retrieval services.  ...  The approach is based on named-entity recognition applied in a set of search results, and on a graph of documents and identified entities that is constructed dynamically and analyzed stochastically using  ...  The document and entity scores (given by the probabilistic analysis) are exploited for enhancing various IR services, e.g. for query expansion and results re-ranking.  ...

2022 arXiv   pre-print
Passage re-ranking is to obtain a permutation over the candidate passage set from retrieval stage.  ...  Specifically, we employ the existing knowledge graph which is incomplete and noisy, and first apply it in passage re-ranking task.  ...  Thus we propose Knowledge Enhanced Re-ranking Model (KERM), which utilizes external knowledge to explicitly enhance the semantic matching process in PLM based re-rankers.  ...

2020 IEEE Access  
This paper proposes a novel text-enhanced knowledge graph representation model, which can utilize textual information to enhance the knowledge representations.  ...  However, previous work fails to incorporate the complex structural signals (from structure representation) and semantic signals (from text representation).  ...  To overcome this problem, we seek help from the beneficial semantic signal from knowledge graph representation learning for enhance the semantic robustness of textual relation representation learning,  ...
