A Knowledge-Based Filtering Method for Open Relations among Geo-Entities

Li Yu, Peiyuan Qiu, Jialiang Gao, Feng Lu
2019 ISPRS International Journal of Geo-Information  
We propose a method for filtering geo-entity relations based on existing knowledge bases (KBs).  ...  Our method takes full advantage of existing KBs to assess the quality of geographical information in web text, which is helpful to improve the richness and freshness of geographical KGs.  ...  Acknowledgments: We also thank the anonymous referees for their helpful comments and suggestions. Conflicts of Interest: The authors declare no conflict of interest.  ...

On Evaluating Embedding Models for Knowledge Base Completion

Yanjie Wang, Daniel Ruffinelli, Rainer Gemulla, Samuel Broscheit, Christian Meilicke
2019 Proceedings of the 4th Workshop on Representation Learning for NLP (RepL4NLP-2019)  
In this paper, we study the question of how well recent embedding models perform for the task of knowledge base completion, i.e., the task of inferring new facts from an incomplete knowledge base.  ...  These models learn latent semantic representations for the entities and relations in a given knowledge base; the representations can be used to infer missing knowledge.  ...  In this paper, we aim to study the performance of popular embedding models for the task of knowledge base completion (KBC): given a relation of a knowledge base (bornIn), infer true missing facts ((Einstein  ...

Hypergraph-of-Entity: A General Model for Entity-Oriented Search [article]

José Devezas, Sérgio Nunes
2021 arXiv   pre-print
The hypergraph-of-entity was conceptually proposed as a general model for entity-oriented search. However, only the performance for ad hoc document retrieval had been assessed.  ...  We find this to be a viable model that is, to our knowledge, the first attempt at a generalization in information retrieval, in particular by supporting a universal ranking function for multiple entity-oriented  ...  in the knowledge base.  ...
