Niclas Heilig, Jan Kirchhoff, Florian Stumpe, Joan Plepi, Lucie Flek, Heiko Paulheim
2022 arXiv   pre-print
Such knowledge can be coded in a knowledge graph -- encompassing diseases, symptoms, and diagnosis paths.  ...  At the same time, for deployment in a hospital, the diagnosis must be explainable and transparent. In this paper, we present an approach using diagnosis paths in a medical knowledge graph.  ...  We introduce the medicalvalues knowledge graph in section 3, and outline our refinement approach in section 4, followed by an evaluation in section 5.  ...

Integration of semantic-based bipartite graph representation and mutual refinement strategy for biomedical literature clustering

Illhoi Yoo, Xiaohua Hu, Il-Yeol Song
2006 Proceedings of the 12th ACM SIGKDD international conference on Knowledge discovery and data mining - KDD '06  
We introduce a novel document clustering approach that overcomes those problems by combining a semantic-based bipartite graph representation and a mutual refinement strategy.  ...  The primary contributions of this paper are the following. First, we introduce a new representation of documents using a bipartite graph between documents and co-occurrence concepts in the documents.  ...  ACKNOWLEDGEMENTS This research work is supported in part from the NSF Career grant (NSF IIS 0448023), NSF CCF 0514679 and the research grant from PA Dept of Health  ...

K-Graph: Knowledgeable Graph for Text Documents

Varsha Mittal, Durgaprasad Gangodkar, Bhaskar Pant
2021 Journal of KONBiN  
An approach called Knowledgeable graphs (K-Graph) is proposed to capture semantic knowledge. Documents are stored using graph nodes.  ...  The authors propose an approach that will reduce the data redundancy to a larger extent.  ...  But the approaches that work on graph similarity-based methods are computationally expensive [19] .  ...

Knowledge-driven Site Selection via Urban Knowledge Graph [article]

Yu Liu, Jingtao Ding, Yong Li
2021 arXiv   pre-print
To get rid of the dilemma, in this work, we borrow ideas from knowledge graph (KG), and propose a knowledge-driven model for site selection, short for KnowSite.  ...  However, existing data-driven methods heavily rely on feature engineering, facing the issues of business generalization and complex relationship modeling.  ...  With domain entities as nodes and semantic relations as edges, KG could integrate multisource data into a graph structure, and then powerful knowledge representation learning (KRL) methods are developed  ...

Object Detection Meets Knowledge Graphs

Yuan Fang, Kingsley Kuan, Jie Lin, Cheston Tan, Vijay Chandrasekhar
2017 Proceedings of the Twenty-Sixth International Joint Conference on Artificial Intelligence  
In this paper, we propose a novel framework of knowledge-aware object detection, which enables the integration of external knowledge such as knowledge graphs into any object detection algorithm.  ...  The framework employs the notion of semantic consistency to quantify and generalize knowledge, which improves object detection through a re-optimization process to achieve better consistency with background  ...  Evaluation We empirically evaluate the proposed approach on two benchmark datasets.  ...

CSKG: The CommonSense Knowledge Graph [article]

Filip Ilievski, Pedro Szekely, Bin Zhang
2021 arXiv   pre-print
Sources of commonsense knowledge support applications in natural language understanding, computer vision, and knowledge graphs. Given their complementarity, their integration is desired.  ...  We analyze CSKG and its various text and graph embeddings, showing that CSKG is well-connected and that its embeddings provide a useful entry point to the graph.  ...  We applied this representation approach to consolidate a commonsense knowledge graph (CSKG) from seven very diverse and disjoint sources: a textbased commonsense knowledge graph ConceptNet, a general-purpose  ...
